ThesisItem Open Access Phytochemical analysis and antioxidant potential of banana (Musa spp)(Department of Home Science, College of Agriculture, Vellayani, 2016) Siji, S; KAU; Nandini, P VThe research project entitled “Phytochemical analysis and antioxidant potential of banana (Musa spp.)” was conducted at College of Agriculture, Vellayani, Trivandrum during 2014-2016 with objectives to study the phytochemical, nutrient, chemical composition and antioxidant potential of the selected banana varieties and to assess its therapeutic value. Eight varieties of banana viz., Palayankodan, Rasakadali, Poovan, Robusta, Red banana, Nendran, Kadali and Padatti were selected for the study. The banana varieties were procured (when the characteristic fruit colour develops) from Instructional Farm, Vellayani or from local markets of Trivandrum. The chemical and nutrient composition, phytochemical and antioxidant activity, sensory evaluation and therapeutic value of the selected banana varieties were ascertained. Results of chemical and nutrient composition revealed that TSS of banana varieties was ranged between 17.830 Brix to 23.900 Brix. TSS was found to be more in Kadali (23.900 Brix) followed by Rasakadali (23.830 Brix) and Nendran (220 Brix). Significant differences were noticed in the acidity of banana varieties studied. The varieties Kadali (0.46%) and Robusta (0.47%) were found to be less acidic. Maximum Acidity was noticed in Poovan (1.28%). The varieties Kadali (0.46%) and Robusta (0.47%) were found to be less acidic. The variety Nendran exhibited highest carbohydrate content (41.33g/100g) where as protein content was found to be higher in variety Poovan (1.37g/100g). Total mineral content of banana varieties ranged between 0.17g- 0.70g/100g and varieties such as Rasakadali (260 mg/100g) and Nendran ( 546.66 mg/100g) exhibited highest content of Na and K respectively. The calcium content of the selected banana varieties ranged between 0.35-1.35 mg/ 100g. Quantitative estimation of phytochemicals revealed that total alkaloid content of the banana varieties was observed to range between 0.84 – 3.76 per cent. The varieties Nendran (3.76%) and Padatti (3.72 %) were found to be having maximum alkaloid content. Whereas variety Rasakadali exhibited highest flavonoid content (9.49 mg/100). Saponin content of banana varieties was found to be ranged between 0.22 -0.82 per cent. The saponin content was found to be maximum in variety Kadali (0.82 per cent) and minimum in variety Padatti (0.22 per cent). Total phenol content was found to be more in varieties Kadali (11.6 mg/ 100g), Poovan (7.19 mg /100g), and Rasakadali (6.76 mg/100 g). The variety Palayankodan (4.28mg/100g) showed maximum tannin content and was significantly different from the other varieties. Antioxidant activity in the present study revealed that variety Red banana showed highest β carotene and (8.53 μg/100g). Ascorbic acid content of banana varieties ranged between 1.52 - 5.35 mg/100g. Highest ascorbic acid content was noticed in Red banana (5.35 mg). Highest dopamine content was exhibited in variety Robusta (13.3 mg/100g) and lowest was found in variety Rasakadali (3.2mg/100g). Free radical scavenging activity of banana varieties were studied by DPPH radical assay and total antioxidant activity using different solvents such as petroleum ether, methanol and water. The results revealed that variety Robusta had the highest DPPH activity with an IC50 value of 43.6 μg/ ml in petroleum ether solvent. With regard to total antioxidant activity, variety Padatti exhibited highest activity with an IC50 value of 41.2 μg/ ml in petroleum ether while variety Rasakadali (48.4) and Poovan (48.4) showed maximum activity in methanol followed by variety Red banana with an IC50 value of 44.4 μg/ ml in methanol. Sensory evaluation of eight banana varieties was done using a 5 point score card and 9 point hedonic rating scale. The results revealed that varieties Rasakadali and Red banana were most consumer acceptable varieties compared to other varieties. The therapeutic value of the banana varieties were studied by determining glycemic index. The lowest glycemic index was noticed in variety Padatti (60.70) followed by Poovan (61.00). Findings of the present study revealed that banana is rich in various health beneficial chemical components and nutrients, bioactive compounds such as ascorbic acid, beta carotene, dopamine, tannins, saponins, alkaloids and flavonoids having potent antioxidant activities and/ or free radical scavenging activity.ThesisItem Open Access Nutritional awareness among the participants of national nutritional anaemia prophylaxis programme(Department of Home Science, College of Agriculture, Vellayani, 2007) Bhuvaneshwari, P; KAU; Geetha, PIron deficiency anaemia is a major global nutritional problem and is prevalent in 50-80 per cent of population in different parts of India. Towards reducing anaemia, the government of India (GOI) launched the National Nutritional Anaemia Prophylaxis Programme (NNAPP) in 1970.National Anaemia control and Prophylaxis Programme has been fighting the relentless struggle to control the ailment since 1970, but has not yielded much. Hence a study entitled “Nutritional awareness among the participants of NNAPP” was undertaken to elicit the existing knowledge, attitude and practice on the programme among the participants identify the lacunae and to suggest correct preventive measures among the participants and to study its impact through KAP studies. For pre test and posttest of knowledge and attitude suitably structured and pre test checklists were used. The dietary practice was assessed through food use frequency studies before and after the education programme. The regularity in the consumption of IFA tablets by the beneficiaries was studied before and after the intervention on consumption basis. The data pertaining to the socio economic and personal characteristics, health and nutritional profile and their participation in the NNAPP of the participants were ascertained with the help of a structured and pre tested interview schedule. The collected data were tabulated, analysed statistically and the results were interpreted. Majority of the selected participants (84 per cent) in the study belonged to the age group of 21-30 years. Nearly 59 per cent belonged to Hindu community. Most of the participants were from nuclear family with medium level of education, low monthly income and moderate physical amenities. Majority of the families possessed television and radio in their homes and 72 per cent of the participants were members of one or other organization. Anthropometric measurements revealed that body mass index of 50 per cent of the women beneficiaries were found to fall in the normal range, weight for height of child beneficiaries revealed that only 31 per cent were normal, 47 per cent were stunted and remaining 20 per cent of the child beneficiaries were stunted and wasted. Haemoglobin level of the beneficiaries revealed that only 17 per cent were normal.40 percent were moderately anaemic and 37 per cent had mild anaemia. However 6 per cent were found to be severely anaemic. Mean food intake of the beneficiaries revealed that the food group, which met the RDA least, was green leafy vegetables followed by fruits, milk and milk products, fats ad oils, and even sugar. Mean nutrient intake of the women beneficiaries revealed that iron, vitamin B12, vitamin C and folic acid were far below the RDA stipulated. Mean nutrient intake of the child beneficiaries indicated that energy, protein, iron, vitamin C and folic acid were below the RDA. Nutritional Status Index of the beneficiaries indicated medium and high Nutritional Status Index among 81 per cent of the beneficiaries and only 19 per cent of the beneficiaries were in the low Nutritional Status Index. Majority of the participants relied more on the anganwadi workers than the PHC staff for iron and folic acid supplements. Less than 25 per cent of the participants participated in the meetings, campaign, nutrition and health education classes consistently.52 percent of the beneficiaries never consumed the IFA tablets. Participation Index of the beneficiaries in the programme related activities of PHC revealed that 58 per cent had medium level of Participation Index. Data collected on the constraints faced by the beneficiaries revealed that irregular supply of supplements, gastro intestinal side effects, forgetfulness, blind beliefs and lack of awareness were the constraints experienced by the beneficiaries/participants. The pre test scores revealed the lack of knowledge of the participants about various aspects of anaemia and its prevalence, role of iron and dietary modification, and anaemia control progrmme objectives. The education programme of three days duration was conducted for the benefit of the participants to impart required information on the above areas. The education programme had significant effect on the gain in knowledge as well as change in attitude and extent of adoption of practices. Correlation of selected independent variables of participants on the knowledge, attitude and practice revealed that there was significant positive correlation was observed with educational status, participation index and knowledge. Significant positive correlation was observed with age, educational status and attitude. Comparison of mean scores of pre test and post test knowledge, attitude and practice revealed that education programme had significant improvement in the awareness of the participants.ThesisItem Open Access Nutritional profile of preschool children belonging to tribal families in Thrissur district(Department of Home Science, College of Horticulture, Vellanikkara, 2016) Vidya, T A; KAU; Seeja Thomachan, PanjikkaranThe study entitled “Nutritional profile of preschool children belonging to tribal families in Thrissur district” was conducted to know the socio-economic status and food consumption pattern of the tribal families. The study also assessed the dietary habits and nutritional status of preschool children belonging to the age group of 4 to 6 years. Sample consisted of 75 preschool children of 4 to 6 years in the tribal areas of Thrissur district. The subset of tribal and non tribal families constituting 15 tribals and 25 non tribals were used for comparative evaluation of anthropometric measurements, clinical examination, food weighment and haemoglobin estimation. Nuclear family system was found in most of the families. All the families were literate. All the families lived in their own houses and majority had 2 rooms (68.00 %) with mud flooring (58.67 %) and terraced roofing (70.67%). Majority of the families earned a monthly income between Rs. 1000 - 2000. Majority of the children had low birth weight of less than 2.5 kg. Sixty four per cent of the children suffered from various types of diseases during the last one year. Immunization of the children was ascertained. Food consumption survey revealed that all of them were habitual non vegetarians with rice as their staple food. Pulses, roots and tubers and other vegetables were included frequently in their daily diet and the use of green leafy vegetables, milk and milk products and fruits were occasional. Different grades of malnutrition were identified among the children using anthropometric indicators. The mean height and weight of the preschool children were lower than the ICMR standards and the deviations were statistically significant. It was also found that the boys were taller and heavier than the girls. Mean head circumference, chest circumference and MU AC in comparison with NFI standards were significantly lower in boys as well as girls. Height for age which reflects the past nutritional status was normal only in 35.70 per cent boys and 27.70 per cent girls. The present nutritional status of the child represented by the weight for age showed mild and moderate malnourishment in 78.60 per cent boys and 87.20 per cent girls. The Quetelet index also showed prevalence of malnutrition in 60.71 per cent boys and 59.57 per cent girls. The nutritional status of the tribal preschool children was compared with the non tribal children and the tribal children were found to be more malnourished than the non tribal children. The mean height, weight, head circumference, chest circumference and MUAC were lower in all the children, with the tribes having lower measurements than the non tribals. The height for age, weight for age and Quetelet index showed higher level of malnutrition in tribal children as against the non tribal children. Food weighment survey was also carried out to know the actual food and nutrient intake. The actual food and nutrient intake asserted that all the children had an intake lesser than the RDA. Gross deficit in the intake of certain food groups such as milk and fruits and nutrients such as iron, vitamin A and vitamin C were noticed among all the preschool children. The food and nutrient intake of tribal children were lower than that of the non tribal children. Mild anaemia was noticed among 66.67 per cent of tribal and 40 per cent of non tribal children. Food security among the tribal families recorded as per USDA module revealed 64 per cent of the families as food secure and 32 per cent of the families as food insecure without hunger and 4 per cent as food insecure with moderate hunger. The present study thus assure the fact that malnourishment is still a major concern among the tribal preschool children.ThesisItem Open Access Quality assessment and development of product from annona(Annona spp.)(Department of Home Science, College of Agriculture, Vellayani, 2016) Aswathy, K M; KAU; Nirmala, CThe research project entitled “Quality assessment and development of product from Annona (Annonaspp.)” was conducted at College of Agriculture, Vellayani, Thiruvananthapuram during 2014-2016 with the objective to analyze the physico chemical and nutritional composition of Annonaceous fruits and to develop a value added product. Three spp. of fruits viz., Bullocks heart (Annona reticulata), Sweetsop (Annona squamosa)andSoursop (Annona muricata)were selected for the study. The quality of fresh fruits was assessed in terms of physical characteristics, sensory acceptability, nutrient analysis, chemical components and shelf stability. The Total Antioxidant Activity (TAA) was also studied. Fruit nectar was standardized from the extracted pulp at different proportions of 20, 25, 30, 35 per cent level and the best proportion was identified based on sensory scores. Physical characteristics such as fruit weight, pulp weight, seed weight and weight of inedible portion were noted. Annona squamosa was smaller in size and 4-5 fruits weighed 1 kg, while 3-4 fruits weighed 1 kg in case of Annona reticulata. Annona muricatawas comparatively large in size, 2 fruits weighed 1 - 1½ kg. Results of quality analysis of fresh fruits revealed that pulp weight, ranged between 344 g to 611 g/kg fruit. Highest pulp weight was observed in Annona muricata (611g/kg). Weight of seed (113.81g/kg) and weight of inedible portions (542.80g/kg)were higher in Annona reticulata.Sensory acceptability of the fruits were evaluated and the overall mean score for the selected fruits were found to range from 6.2 to 8.8. Maximum mean score was secured for Annona squamosa(8.8) followed by Annona muricata(8.6) and Annona reticulata (6.2). Keeping quality of the annonaceous fruits were assessed by noting their organoleptic parameters on alternate days until spoilage. It was found that all the three fruits had maximum keeping quality of seven days. Quantitative estimation of major nutrients revealed that highest content of carbohydrate, energy and fat were noticed in Annona reticulata (25.12 g, 108.40 kcal, 0.61mg/100g respectively). Whereas Annona muricata exhibited highest moisture content (82.46 %). Protein content was found to be higher in Annona squamosa (2.05 mg/100g). TSS content of the selected fruits ranged from 18 – 250 Brix. The fruits were rich in potassium, calcium, magnesium, phosphorus and iron.The fruits exhibited very low fat content. Annona reticulatawas composed of 65.09μg of β caroteneper 100 gram and Annona squamosarecorded a vitamin C content of 36.20 mg/100g.Oxalates and total phenol content was higher in Annona muricata (3.36 mg/100g, 21.72 mg/100g respectively). Acidity of the selected fruits ranged from 0.27 to 1.07 per cent. Total antioxidant activity of selected fruits were studied by using different solvents such as petroleum ether, methanol and aqueous medium. The results revealed that Annona squamosa had highest antioxidant activity with IC50 value of 32.00 μg/ ml in petroleum ether. Fruit nectar was standardized from fruit pulp. Four treatment with differentproportions of fruit pulp (per cent)20 (T1), 25 (T2), 30 (T3) and 35 (T4) were developed and initial sensory analysis was done to identify the best proportion for further storage study.Selected best proportions of the fruit nectarfromAnnona reticulata (T3), Annona squamosa (T3), Annona muricata (T4) were stored at room temperature for monitoring the shelf stability in terms of changes in sensory parameters, acidity and microbial contamination periodically. The samples were analysed at weekly interval during the storage period. The stored fruit nectar was analysed for bacteria, fungi and actinomycets. No bacteria, yeast, actinomycets growth was found during the storage periodupto three weeks.An increase in acidity was noted during storage.Shelf stability of the developed product fruit nectar was found to be three weeks at ambient temperature. Annonaceous fruits possess great nutritional and health benefits through the supply of natural antioxidants and other bioactive components. Among the three spp. Annona squamosa was observed with higher antioxidant activity.Annonaceous fruits keeps well for 7 days at ambient temperature. Acceptable fruit nectarwas developed from the fruits with three weeks shelf stability at ambient temperature. Hence promoting the cultivation in large scale and scaling up the production will help to improve the health status and economic prosperity.ThesisItem Open Access Quality analysis and culinary utilization of cashew apple (Anacardium occidentale L.)(Department of Home Science, College of Agriculture, Vellayani, 2016) Neethu, Mohan; KAU; Nirmala, CThe present investigation entitled “Quality analysis and culinary utilization of cashew apple (Anacardium occidentale L.)” was conducted at the Department of Home Science, College of Agriculture, Vellayani, during the period October 2015 – May 2016. The objective of the study was to analyze the qualities of cashew apple and to evaluate its use in culinary preparations. Cashew apple needed for the study was procured from State Seed Farm, Kottarakara, Instructional Farm, College of Agriculture, Vellayani and also from local sources. The collected Cashew apple was pre-treated to remove the astringent content by steaming for 5 minutes under pressure (T1), boiling in 2 per cent salt solution for 5 minutes (T2), immersing fruit in rice gruel extract for 30 minutes (T3), immersing fruit in 0.55 per cent gelatin solution for 10 minutes (T4) and immersing fruit in 5 per cent salt solution for 3 days with the change of salt solution daily (T5). Fresh cashew apple served as control (T6). After the pre - treatment process, samples were subjected to physical, chemical and nutrient analysis. Based on the analysis of samples the treatment with least content in astringent principles (polyphenol and tannin) and with highest sensory scores were selected and stored in glass containers under refrigeration for storage study. Physical appearance and colour, fruit flavour, texture, taste and overall acceptability of treated and fresh cashew apples were evaluated by a panel comprising of 10 members using a 5 point score card. Based on the mean scores, the best treatment was identified which was T2 (Cashew apple treated in 2 per cent salt solution for 5 minutes). Chemical analysis of fresh and treated Cashew apple observed that a reduction in the chemical constituents in treated Cashew apples compared to T6 (Fresh cashew apple). It was found thatT2was in least content in polyphenol (0.11 per cent) and tannin (0.07per cent) hence selected for further in depth study. Nutrient analysis showed that the values obtained for different nutrients were lower for treated cashew apple. T2 sample got comparatively higher values than other treatments in carbohydrate (11.30g) vitamin C (180.00mg) and potassium (75.20 mg) and was also on par with control (T6). Treated cashew apple sample T2 and control T6 were stored in glass containers under refrigeration for storage study. The study showed no significant change in moisture content of the stored samples. With respect to acidity,T6 showed significant increase but not in T2. Microbial growth was seen in T2 sample on the 5th day and in T6 sample on the 7th day of storage. Cashew apple powder was also prepared from selected treatment T2 and fresh cashew apple T6 and denoted as T2P and T6P which was also used in culinary preparations. Four types of culinary preparations such as Cashew apple gravy preparation (Masala curry), Cashew apple salad, Cashew apple sweet chutney and Cashew apple sweet meat product (payasam) were made from T2andT6. Sensory acceptability of these preparations was tested by 10 panel members using 5 point score card and preference was assessed using 9 point hedonic rating scale. These four preparations were also made using cashew apple powderT2P and T6P and evaluated. Results of the organoleptic evaluation of culinary preparations from T2, T6, T2P and T6Psecured highest mean preference score for cashew apple salad (8.8/9) prepared from T2 followed by Cashew apple payasam (8.7/9) from T6 and Cashew apple chutney (8.7/9) from T2P. Cashew apple masala curry got (8.6/9) from T2. From the above findings, it can be concluded that Cashew apple treated with 2 per cent salt solution (T2) lower the astringent principle and was found to be most suitable for culinary preparations such as sweet meat products, gravy preparations, chutneys and fresh salads.ThesisItem Open Access Assessment of nutritional status and life style diseases among different income groups(Department of Home Science, College of Agriculture, Vellayani, 2016) Priya, P; KAU; Rari, John KThe study entitled “Assessment of nutritional status and lifestyle diseases among different income groups” was carried out at the Department of Home Science, College of Agriculture, Vellayani during the period, 2014-2016. The main objective of the study was to assess food habits, nutritional status and life style diseases among different income groups and impart counselling for a healthy life. Ninety employees (male and female) 30 members in high income group (HIG), 30 members in middle income group (MIG) and 30 members in low income group (LIG) belonging to the age group of 30 to 45 years was selected randomly. The classification of respondents in to different income groups was done according to NSSO report, 2007-2008. Evaluations of the socio-economic characters of the respondents found that majority of the respondents in all groups were females. They were mostly Hindus and majority of them were married. Educational status revealed that43% of LIG respondents were studied up to high school, 40 % of MIG were PGs and 50 % of HIG got Doctorate degree. On evaluating the food habits of the respondents it was found that majority of the respondents in all the three groups were non vegetarian, majority of the respondents(57 % of LIG, 50% of MIG and 77% of HIG) had regularity in their meal timings. Whereas 57% of LIG, 54% of MIG and 27% of HIG respondents had a habit of meal skipping. Thirteen per cent of both LIG as well as MIG and 16% of HIG respondents regularly consumed food from outside. On considering the meal patterns majority of the respondents had cereal, pulse and vegetable combination for their breakfast, lunch and dinner with the inclusion of non vegetarian foods like egg and fish. The food consumption pattern indicates that consumption of fast food was very low. The nutrient intake study revealed that among the three groups energy, protein and calcium intake was below Recommended Dietary Allowance (RDA). The weight for height values showed that majority of the male and female respondents were having a value higher than the standard value. In the case of BMI also it was found that only 3% of males, and 27% female in LIG, 17% of males and 37% female in MIG and 7% of males and 30% of female respondents in HIG had normal values. The WHR of the respondents also indicated higher values than normal. The clinical status of the respondents revealed that symptoms of malnutrition in hair, skin and tongue were observed; thyroid gland enlargement and anaemia were observed. The biochemical assessment conducted by a clinical expert revealed that majority of the respondents in all groups of males (7%, 13%, 10% for LIG, MIG & HIG respectively) were having mild anaemia. Were in the case of females majority of the respondents (40%, 47%, and 30%) were observed in normal level. The blood sugar level of the respondents revealed that (83%) of the respondents in LIG & MIG and 90% of the respondents in HIG were having the normal blood sugar level. Lipid levels also showed similar trends. With regarding the blood pressure values 63 per cent of LIG, 57 per cent of MIG and 60 per cent of the HIG respondents had a normal value. When the health and morbidity pattern of the respondents were assessed, it was found that majority of the respondents in LIG (56%) were not having the habit of exercise and 50% of the respondents in both MIG and HIG were exercising irregularly. The stress pattern of the respondents revealed that majority of the respondents in LIG (27%) were experienced stress due to financial problems, in the case of MIG respondents majority of them expressed the reason for stress as both financial and family problems (20%). In the case of HIG the major reason for the stress was due to occupational problems. The sleeping pattern revealed that majority of the respondents in all groups were having an adequate amount of sleep and there was no relation between stress and sleeping pattern. The lifestyle habits of the respondents like alcoholism, smoking and pan chewing was also assessed and it was found that majority of them did not have these habits in their day today life. The morbidity pattern of the respondents indicates that majority of the respondents had occupational health problems like joint pain, back pain, muscle pain and head ache. The energy intake and energy expenditure of the respondents were assessed and it was found that although energy intake was less from the standards, energy deficit was not observed because the energy expenditure was less than the energy intake and due to the same reason the prevalence of obesity among the respondents was found to be high. An education class on the occurrence, prevalence and importance of lifestyle diseases was conducted for the respondents for a healthy life. A counselling class regarding healthy life was also imparted to the respondents. It was found that the knowledge of the respondents about lifestyle diseases had improved significantly after the conduct of the class. Hence, it can be concluded that although the prevalence of lifestyle diseases among the respondents was not obvious, the chances for their occurrence is very high, because of the hidden risk factors like grade I obesity, hyperlipidimia, prehypertension, hereditary factors and stress related lifestyle problems.ThesisItem Open Access Impact of dietary counseling on the food habits of fisherfolk(Department of Home Science, College of Agriculture, Vellayani, 2007) Ramlath, P H; KAU; Soffi, CherianThe study entitled “Impact of dietary counseling on the food habits of fisher folk” was undertaken with an objective to evaluate the beneficial effects of dietary counseling on the food habits & health related personal habits of fisher folk. The study was carried out among fisher folk at Adimalathura in Trivandrum district. One hundred samples, both men and women in the age group of 40-50 years who were habituated with chewing, smoking and alcoholism were screened for the study. Personal profile of the fisher folk indicated that majority of the subjects were between the age of 46-50 years and all of them belonged to Christian community. Majority of the subjects were illiterate and their occupation is fishing or fish vending. 91 per cent of the families were of nuclear type and it was found that majority of the families were medium to large sized having 6 to 8 members. Majority of the subjects had monthly income ranged between 1000-1250. Most of the families were spending more than 800 rupees on food and up to 400 rupees on medicine. Details on the personal habits of the fisher folk viz. smoking, chewing and alcoholism were collected. Out of the 60 male subjects under study 33.37 per cent of them were smokers and majority of them were accustomed to this habit for more than 20 years. The frequency of smoking revealed that all of them smoke more than 15 times a day. All the subjects both males and females were regular chewers of betel quid. All the respondents used betel, tobacco, chunna and arecanut as ingredients in their chewing quid. Sixty per cent of male and 47.50 per cent of female subjects chew more than ten times a day and also the quid was allowed to remain in the mouth for more than 1½ hours. With regard to alcohol consumption 53.33 per cent of the men folk were regular users of alcohol and the majority started taking alcohol at an early age of 15 years. None of the female subjects were habituated to alcoholism. All the subjects were non-vegetarians and none of them followed a specific meal pattern. Most of the male subjects had the habit of taking food from hotels or restaurants. Frequency of use of various foods revealed that rice, coconut, fish, sugar and beverages like coffee or tea were the food items included daily in their diet. Consumption of egg, pulses, green leafy vegetables, other vegetables and fruits were either occasional or never used in their diet. Male subjects were consuming food items like egg and meat frequently since they take meals outside home. Frequency of use of foods rich in antioxidants & phytochemicals indicated that such neutraceuticals were mostly not included in the diet or occasionally used by the fisher folk. Actual food intake of the male respondents revealed that the diet was satisfactory in all the foods except green leafy vegetables, other vegetables and fruits. Their nutrient intake was also satisfactory except β-carotene when compared to RDA. Actual food intake of the female respondents revealed that their diet was inadequate in all the foods. A deficiency in all nutrients except calcium when compared to RDA was found. Anthropometric data of the subjects showed that majority of the male subjects had normal height, weight and BMI. While majority of the female subjects had poor body parameters for weight, height and BMI. Clinical examination of the fisher folk revealed that deficiency symptoms of vitamin A, vitamin B and vitamin C were observed among the subjects. Majority of the subjects showed symptoms like mottled enamel and dental caries. Clinical manifestations of leukoplakia was observed among 53.33 per cent male and 57.58 per cent female subjects symptoms like Sub Mucous Fibrosis (SMF) and oral ulcers were also present in many of the subjects. Haemoglobin level of the subjects indicated that 18.33 per cent of male and 52.50 per cent of female subjects were anaemic. Morbidity pattern of the subjects for the previous six months of study indicated that chickungunia, chicken pox, skin diseases and malaria were the diseases occurred widely among the fisher folk. The impact of dietary counseling was assessed in terms of changes in dietary habits, personal habits, personal hygiene, general health status and knowledge gain of the subjects. The frequency score of many protective food items (vegetable & fruits) and foods rich in antioxidants & phytochemicals have been increased as an effect of dietary counseling. Counseling could bring beneficial changes in certain unhealthy personal habits of fisher folk viz. smoking, chewing and alcoholism. 30 per cent of the subjects could be motivated to reduce their frequency of smoking. As an effect of counseling majority of the subjects were persuaded to exclude tobacco in their chewing quid and 31.67 per cent of male and 36.67 per cent of female subjects were made to reduce their chewing time. Oral hygiene of the subjects could also be improved. Better personal hygienic habits could be inculcated among the respondents due to counseling. The knowledge level of the fisher folk could also be improved considerably as an impact of dietary counseling.ThesisItem Open Access Quality evaluation of germinated rice and rice products(Department of Home Science, College of Horticulture, Vellanikkara, 2012) Neethu Sathyan, T; KAU; Suman, K TThe study entitled “Quality evaluation of germinated rice and rice products” was undertaken to evaluate the physical, cooking, biochemical, nutritional, organoleptic and keeping qualities of germinated rice. The study also aimed to evaluate the physical and keeping qualities of roasted rice flour and to assess the acceptability of the products prepared with rice flour. The rice variety Jyothi was selected for the study. After soaking for 12hours, it was germinated under laboratory conditions. The treatments were T0 – Ungerminated rice, T1- Rice- soaked for 12 hours, T2 – Rice- soaked and kept for germination for 3 days and T3 – Rice- soaked and kept for germination for 6 days. Milling recovery was found to be very low in germinated rice which in turn resulted in higher milling loss. Total milled rice and head rice recovery of germinated rice decreased significantly during storage when compared to control. Significant variation among treatments was observed with respect to thousand grain weight and thousand grain volume. To obtain optimum cooked rice, a cooking time of 22.33 to 29.33 minutes was noticed among different treatments. A positive correlation between water uptake, volume expansion and grain elongation was noticed in all the treatments. Germination decreased the amylose content thereby affecting the gel consistency. Intermediate gelatinisation temperature index was noticed in all the treatments. Moisture content of rice from four treatments varied from 10.51 to 12.67 per cent which increased significantly during storage. A significant increase in total and reducing sugar was observed as a result of starch degradation during germination. Variations were noticed in the protein, fat and fibre content among treatments. Progressive increase in the thiamine content was observed with advancement in days of germination. Compared to control, calcium, iron and phosphorus content of germinated rice were significantly low. During germination, in vitro starch digestibility of rice from different treatments increased by 5 to 17 per cent. Significant increase in in vitro mineral availability was also noticed. Bulk density of roasted rice flour from different treatments varied from 0.78 to 0.84 g per ml. Compared to control, lower water absorption index and higher water solubility index was noticed in roasted rice flour from germinated rice. The evaluation of retrogradation property in roasted rice flour from different treatments revealed that syneresis per cent increased with advancement in days of observation. Maximum syneresis was noticed in germinated rice. The products prepared using rice (cooked rice, unniappam and kozhukatta) and rice flour (iddiappam and puttu) from germinated paddy had mean scores above 6.0 for different quality attributes. Germinated rice was found to be more suitable for the preparation of unniappam and puttu. Mean scores for various quality attributes increased when the products were prepared from stored rice and rice flour. The rice and roasted rice flour were evaluated for the presence of bacteria, fungi and yeast initially and after three months of storage. Presence of bacteria was detected in both periods under study. Fungal growth was not noticed in any of the rice and rice flour samples initially but after three months of storage fungal growth was detected in roasted rice flour of T0 and T1. Yeast count was not detected in rice and rice flour initially and after three months of storage. Insect infestation was not noticed in rice and rice flour from different treatments throughout the storage period.ThesisItem Open Access Quality evaluation of newly released KAU rice (Oryza sativa L.) varieties and their suitability for traditional food products(Department of Home Science, College of Horticulture, Vellanikkara, 2015) Chandhni, A A; KAU; Aneena, E RThe present study entitled „Quality evaluation of newly released KAU rice (Oryza sativa L.) varieties and their suitability for traditional food products‟ was conducted to evaluate the physical, biochemical, nutritional, cooking and organoleptic qualities of newly released KAU rice varieties. The study also aimed to assess the suitability of these rice varieties for the preparation of selected traditional food products. Milling per cent among rice varieties varied from 64.07 per cent in Prathyasha (MO-21) to 77.83 per cent in Ezhome-2. Vyttila-8 obtained the highest head rice recovery of 57.45 per cent while it was lowest in control variety Jyothi (41.08 per cent). The highest thousand grain weight (20.68 g) and volume weight (14.6 mm3) was observed in Vaishak (PTB-60). Based on the L/B ratio, the grain shape of Ezhome-1, Vyttila-8, Vaishak (PTB-60) and Uma were classified as bold medium. Ezhome-2, Prathyasha (MO-21) and Jyothi varieties were categorised as slender long grains. For most of the physical quality parameters, raw rice of newly released varieties were found to be superior over the control varieties Jyothi and Uma. Newly released rice varieties obtained lower total index for organoleptic qualities than control varieties. Ezhome-2 obtained highest total index for table rice among newly released varieties. Among rice varieties, lowest cooking time of 18.51(Prathyasha (MO-21)) to highest of 24.75 (Ezhome-2) minutes was noticed for obtaining optimum cooked rice. Highest water uptake of 5.74 ml/ g was observed in Ezhome-2 and lowest of 3.3 ml/ g in Jyothi. Control varieties Jyothi and Uma obtained volume expansion ratio of 5.62 and 6.07 respectively, which was higher than that of the newly released rice varieties. Among rice varieties, amylose content varied from 10.20 per cent in Prathyasha (MO-21) to 23.32 per cent in control variety Uma. Gel consistency of different rice varieties was determined and it varied from 27.50 to 145 mm. Cooking qualities of the newly released rice varieties were found to be comparable with that of the control varieties. Among newly released rice varieties, higher grain elongation ratio of 0.90 was noticed in both Ezhome-2 and Prathyasha (MO-21). Maximum keeping quality up to 12.60 hours was noticed in Vaishak (PTB-60) and minimum of 11.24 hours in Prathyasha (MO-21). The moisture content of different rice varieties ranged from 8.5 per cent in Ezhome-2 to 11.6 per cent in Ezhome -1 and Prathyasa (MO-21). The highest total carbohydrate, starch, energy, protein, zinc and phosphorous content was noticed in newly released rice variety Ezhome-2. Fat content in different rice varieties ranged from 0.30 per cent in Ezhome-2 to 0.71 per cent in Vaishak (PTB-60). The highest fibre content of 0.7 g/ 100g was noticed in Ezhome-1. Maximum thiamine content of 0.07 mg/ 100g was noticed in Vaishak (PTB-60). The highest calcium and iron content was noticed in Jyothi and Prathyasha (MO-21) respectively. Newly released rice varieties were found to be superior to control varieties in nutritional qualities. In the case of unroasted rice flour, highest bulk density of 0.73 g per ml was noticed in Ezhome-2 and the lowest of 0.63 g per ml in Jyothi. In roasted rice flour, the highest bulk density of 0.62 g per ml was observed in control variety Uma. The highest water absorption index of 25.46 was observed in unroasted rice flour of variety Jyothi (control) and 25.11in roasted rice flour of Uma (control). Highest water solubility index of 0.78 was observed in unroasted rice flour of Vyttila-8 and the lowest of 0.34 in Ezhome-1. In roasted rice flour the highest water solubility index of 0.81 was noticed in Ezhome-2 and the lowest in Vyttila-8 (0.28). At the end of the 12th day of study the highest synerisis per cent in unroasted rice flour was noticed in Vyttila-8 and that of roasted rice flour in Ezhome-1. Physical properties of rice flour of newly released rice varieties were comparable with that of the control varieties. Evaluation of microbial qualities indicated that at the end of 6th month of storage bacterial count and fungal growth was observed in raw and roasted flour of different rice variety. Yeast was not observed in any of the raw rice and roasted rice flour of different varieties till 5th month of study. Vyttila-8 was found to be the most suitable rice variety for the preparation of rice flakes and unniyappam. The most suitable variety for the preparation of cooked rice and iddli was control varieties Jyothi and Uma respectively. Prathyasha (MO-21) was found to be the most suitable variety for the preparation of appam and ada and is also suited for idli. Vaishak (PTB-60) was the most suitable rice variety for puttu. In the present study, It was observed that newly released red rice varieties were suitable for the preparation of different traditional food products.
