ThesisItem Open Access Nutritional status of women engaged in fishvending in Thivandurm district(Department of Home Science, College of Agriculture, Vellayani, 1993) Karuna, M S; KAU; Prema, LThe study on the “Nutritional status of women engaged in fishvending in Trivandrum District” comprises of the socio-economic and food consumption pattern of the fisherwomen families with special reference to their actual food intake, energy expenditure and nutritional status. Families surveyed were nuclear type belonging to under privileged communities. Main occupation of the families was fishing and fishvending. Most of the families belonged to the income groups of Rs.1000 to 2000. In these families as the income increased the percentage of income spent on food items decreased. Expenditure on education and health was very low. Male members spent much money for their faulty habits like alcoholism and playing cards. Most of the families were in debts and only women were responsible for the economic management of the families. Index developed from various socio-economic variables revealed that all the families lived below the poverty line. All the families were non-vegetarians and fish was the main nonvegetarian food in their diet. However, consumption of vegetables, pulses, eggs and green leafy vegetables was less due to lack of knowledge about nutritious food. Preparation of food is not upto the standard and this results in the poor quality of the food. Unbalanced, monotonous meal pattern was observed in the community. Compared to other stages of life, special attention was given only during infancy and pre-school period. Besides fishvending women were responsible for household tasks and child care practices. The women got employment for 7 months in a year. Most of the women sold the fish either in the markets in the city or by home to home delivery. Income getting from fishvending was not in proportion to the distance covered. Time spent for fishvending activity was more than the time they spent for other activities. Most of the household activities were combined with fishvending activities. It was found that total time spent for fishvending and household activities was more than 10 hours in a day. Time spent for fishvending activities was positively associated with family income, age of the fisherwomen and income of the fisherwomen. Compared to recommended daily allowance, higher energy expenditure was noticed in all the fisherwomen studied. Majority of the women were below the normal weight. Body Mass Index of the women showed that 33.33 percent suffered from energy deficiency. Nutritional status index was developed from height, weight and body mass index. The index developed ranged from 14.04 to 18.58. A highly significant positive association was observed in between nutritional status index of the women and their height, weight, BMI, Index developed from socio-economic factors and their energy expenditure. Clinical examination of the fisherwomen revealed that 95.33 percent of the women were suffering from any one of the nutritional deficiency disorders. Consumption of food quantity and availability of nutrients from the food were not satisfactory. The nutrients like energy, calcium, iron , retinol, thiamine , niacin and riboflavin and Vitamin C were deficient in their diets. As a result nutritional deficiency symptoms were more prevalent among them. Energy expenditure was more than the intake of energy. Blood constituents like haemoglobin, total protein albumin and Vitamin A were deficient in many of the women studied. From the above findings it was concluded that the nutritional status of the fisherwomen was found to be affected by geographic, environmental and disease factors.ThesisItem Open Access Effect of iron and vitamin supplementation on iron profile of anemic adolescent girls(Department of Home Science, College of Agriculture, Vellayani, 1999) Kavita, M S; KAU; Prema, LThe study entitled, "Effect of iron and vitamin supplementation on iron profile of anemic adolescent girls", was conducted to assess the magnitude of iron deficiency anemia among adolescent girls; to find out the direct and indirect effects of causative factors and to evaluate the relative effect of supplementation of iron with vitamins on the iron status of anemic adolescent females. The study was limited to Neyyattinkara, Nedumangadu and Trivandurn Taluks of Trivandrum district. Rapid assessment technique was administered to determine haemoglobin and to indentify 225 adolescent girls suffering from iron deficiency anemia (with Hb ::::;; 12g1dl). Socio economic status of the girls was determined by using a suitably structured schedule while nutritional variables responsible for the incidence of anemia were determined through assessing their mean food intake by 24 hour recall method and by ascertaining their anthropometric measurements using universally accepted techniques. Clinical examination was conducted to assess the health variables responsible for iron deficiency anemia. A metabolic experiment of two months duration was conducted to find the effect of iron and vitamin supplementation on iron profile of the moderately anemic girls. For this, the basal diet which gave RDA of nutrients was supplemented by 60 mg iron and 500 ug folic acid, 600 /-lg equivalent vitamin A, 1.2 mg equivalent vitamin B~ and ~ 40 mg equivalent vitamin C in different treatment groups either in the form of tablets 351 Supplements in the form of tablets produced highest and rapid changes in haematological and iron profile while the greatest positive changes in growth and physical endurance were observed when the supplements were given in the form of food. Hence for proper iron nutriture, iron source with high bioavailable iron is necessary along with balanced intake of other nutrients.ThesisItem Open Access Nutritional status of ICDS (Integrated child development services) beneficiaries with respect to participation(Department of Home Science, College of Agriculture, Vellayani, 1993) Mary Ukkuru, Pulikkottil; KAU; Prema, LA study entitled “Nutritional status of ICDS (Integrated Child Development Services) beneficiaries with respect to participation" was carried out' in Malappuram district selecting 170 beneficiaries representing three categories via preschool children, pregnant mothers and lactating mothers and 70 nonbeneficiaries from similar socio-economic background far parnparison. The study enlightened the socio-economic and personal characteristics of the respondents, appraisal of the programme implemented in the area, nutritional status of the respondents through dietary, food consumption, anthropometric, clinical and biochemical parameters, participation index and nutrtianal status index of the respondents, and the interre1 ationhip between participation index and nutritional status index. Major findings Majority of the respondents were from Hindu community. Joint family system with 'small family norm' prevailed in the area. Major expenditure is for food. Beneficiaries had the correct perception about the ICDS programme. Their, highest preference was for supplementary nutrition' and least for referral service. Beneficiaries considered supplementary nutrition most useful followed by immunization and ‘health check-ups'. "Sharing of the food supplement", incomplete utilization of immunization, Irregular supply of vitamin supplements, lack of motivation for health education calsses, under utilization of referral services were some of the lacunae identified. Anthropometric measurements of the preschool children and that of mother beneficiaries were superior to that of their counterparts in the contorl group. Dietary and food consumption pattern of the experimental group was better than the control group. Nutrient intake was adequate with respect to calories and proteins in both the groups, while other nutrients such as vitamin A, vitamin C, and riboflavin were inadequately met, and were much lower in the control group. Clinical evidence of various deficiency diseases were lower in the experimental group compared to the control group. So also the biochemical parameters. Various socio-economic personal characteristics were not found to influence either the participation or the participation levels of the respondents. The nutritional status index developed wa.s significantly better in the experimental group. Participation index of the beneficiaries was found to be high and nutritional status index increased significantly with participation index in the beneficiaries except in pregnant mothersThesisItem Open Access Developing complementary food products based on Cassava and Sweet Potato(Department of Home Science, College of Agriculture, Vellayani, 1995) Chellammal, S; KAU; Prema, LThe present study on developing complementary foods based on cassava and sweet potato was under taken to utilize the high energy root crops such as cassava and sweet potato for the development of complementary foods and to ascertain their nutritional adequacy, physiological tolerance, organoleptic and shelf life qualities. The survey on the consumption of processed foods indicated that all the families surveyed were aware of the different processed foods available in the market irrespective of the family income. Variables like, food expenditure family income, educational status of the housewife, number of children in the family and family size were found to have a positive correlation with the consumption of processed foods. The employment status of the women had a significant correlation with the consumption of the processed foods. In high income families, the consumption of processed foods was more among unemployed women. Employed women of high middle income families consumed more processed foods than unemployed women of that category. But the employment status of women did not make any significant difference among the middle income families with regard to the consumption of processed foods. Type tests administered for the raw ingredients revealed that the moisture content for all the raw ingredients were lower than ISI specified values. And low moisture values were advantageous in product development. Protein and ash content of certain ingredients were slightly lower than ISI prescribed values but the difference was not statistically significant. Type tests administered for the products revealed that all the characteristics were comparable with ISI specifications. Regarding physical characteristics sweet potato noodles secured lower scores than cassava and standard noodles for different quality parameters. However the developed macaronis were equal or better in physical characteristics. Cooking time for the extruded foods were on par with standard products. The bulk density of standard noodles was significantly lower than cassava and sweet potato noodles. Bulk density of macroni was higher than that of noodles in all the three categories. All the foods developed had essential nutrients in optimum quantity. When the nutrients were computed they were observed to be slightly higher indication loss during processing. The loss was statistically significant for protein and carotene in the extruded foods. Assessment on the physiological tolerance revealed that among the experimental groups weaning mixes exhibited higher values for P.E.R. B.V, D.C and N.P.U which were comparable with the control group. The PER of the developed foods were 1.99 and above, indicating that the quality of protein is good. The study on the organoleptic qualities of the developed food revealed that cassava based foods could be rated as equal or even better on certain quality parameters than standard. Sweet potato based foods secured lower scores. Women from high income group who were the predominant consumers of processed foods, fully agreed with the judgment of technical experts. All the foods developed, were rated positively by majority of the farm women. Regarding shelf life qualities, the storage containers had significant effect on the moisture level and peroxide value of the stored products. However the storage containers did not have any significant influence on the total sugar content. There was increase in all the three quality parameters throughout storage period, the highest being in polythene bags followed by steel containers. There was no insect infestation upto 6 months of storage period irrespective of containers and products . Products stored in glass and plastic containers were free of insect infestation through out the storage period of one year. Among the other two containers the infestation was more in polythene bags than in products stored in steel containers. The insects identified were S.orysae, T.castaneum and A. Fasciculatus. Microbial status after the storage period, revealed that there were five samples in which there was neither fungal nor bacterial growth. Though there was fungal or bacterial growth in other samples the count was within the maximum limit specified by ISI. The technologies developed in the present study could be transferred to unemployed youth and women so that they can start small scale processing units which is the present lacunae in food processing industry in our country.ThesisItem Open Access Assessment of quality of selected varieties of green gram and grain cowpea(Department of Home Science, College of Agriculture, Vellayani, 1996) Jessy Philip; KAU; Prema, LPulses contain several imbibed inhibitors, antinutritional substances and flatulence causing factors which negatively influences their nutritional significance, digestibility and utility value. Studies on processing pulses, indicate a reduction in the above undesirable factors. Comprehensive information regarding the quality of different varieties of pulses evolved and recommended by Kerala Agricultural University are at present not available. Hence in this study, a critical assessment of the quality parameters in selected varieties of cow pea (C 152, V 118, Pournami, Kozhinjipayar and Kanakamany) and greengram (Mg 161, M 3, Co 2, Pusa 8793 and Pusa Baisakhi) were envisaged. The physical, cooking, nutritional and antinutritional qualities were critically assessed to screen the varieties of the two pulses. Effect of processing and cooking methods on the above quality parameters were also ascertained. Salient findings of the study are: 1. Based on the physical, cooking and nutritional characteristics Kanakamany in cowpea and Pusa 8793, M 3 and Mg 161 in greengram were found to be better than other varieties .. pa 2. In Cowpea varieties tannin, phytin and trypsin inhibitorswere lowest in V 118, raffinose in C 152; and stachyose and verbascose in Kozhinjipayar, 3. Among greengram varieties tannin, and verbascose were lowest in M 3; phytin and stachyose in Co 2, trypsin in Mg 161 and raffinose in Pusa 8793. 4. Gel electrophoretic analysis of cowpea and greengram protein revealed their heterogenic nature. 5. Limiting amino acids such as methionine and cystine were highest in Kanakamany (cowpea) and Mg 161 (greengram). 6. Biological experiments revealed that among cowpeavarieties PER and NPUwere high- est for Pournami (1.92) and V 118 (86.13) respectively and in greengram varieties, PER was maximum for Mg 161 (2.83) and NPU was highest for Pusa Baisakhi (84.27). 7. Incorporation of Kanakamany (which was lysine and arginine ratio as 1) in high fat high cholesterol diet decreased the lipid level in liver and serum of experimental ani- mals indicating the hypocholesterolemic effect of Kanakamany. 8. An increase in protein content was observed in the two pulses during germination and germination followed by steaming. 9. A reduction in antinutrients were found during various processing and cooking methods. 10. Soaking and boiling caused maximum reduction in tannin, phytin and trypsin inhibi- tor in the two pulses. 11. Germination and steaming were found to be the most effective method in reducing the flatus producing oligosaccharides viz raffinose, stachyose and verbascose in the two pulses. 12. Application of suitable statistical techniques on the above data revealed the superior- ity of Kanakamany (cowpea) and Mg 161 (greengram) over other varieties.ThesisItem Open Access Multi variate approach to define the quality of rice(Department of Home Science, College of Agriculture, Vellayani, 1995) Nandini, P V; KAU; Prema, LA study on “ a multi variate approach to define the quality of rice” was carried out assets the major quality parameters such as physical characteristics, cooking characteristics, organoleptic qualities and nutritional composition. Sixty rice varieties (thirty hybrid derivatives, twenty eight traditional / local varieties and two other improved / market varieties ) were selected. The programme envisaged not only a detailed study on different quality parameters like physical characteristics, cooking characteristics, organoleptic qualities but also the suitability of the varieties to rice based preparations. Importance was paid to nutritional quality of the varieties. All the above indicators were tested both for raw as well as for parboiled rice. Among the various indicators studied under physical characteristics, in general, thousand grain weight was found to be higher in hybrid derivatives of rice while head rice yield and moisture content in traditional varieties. Process of parboiling was found to increase the thousand grain weight and head rice yield. Less cooking time, less gruel loss, lower viscosity , higher elongation index and elongation ratio were noticed in other improved varieties while higher water uptake and volume of expansion after cooking a desirable trait were noticed in hybrid derivates of rice. As a result of parboiling, optimum cooking time, elongation index and gelatinization temperature were found to increase and there was a decrease in gruel loss, volume expansion and water uptake due to parboiling. Rice based preparations using different cooking methods such as boiling, fermenting and steaming , fermenting and shallow frying, powdering, roasting and steaming, powdering , roasting and boiling and baking attempted. The overall acceptability of the quality attributes revealed the market varieties were found to obtain highest score, followed by traditional and hybrid derivatives. Cluster analysis was carried out to group/cluster the various rice varieties based on their multiple characters. The D2 analysis based on organoleptic qualities revealed that thirty five varieties were found to be homogeneous with respect to the above qualities for the preparation of cooked rice using raw and parboiled rice. Seventeen varieties were selected for nutrient composition on the basis of D2 analysis using physical and cooking characteristics of rice varieties. Parboiling had a positive influence on calorific value, ash and mineral content while negative effect on starch, amylase and protein in all the selected rice varieties. Discriminant function approach was used to discriminate the various varieties of rice based on multiple characters relating to the quality parameters and individual indices were developed for quality parameters and also for various rice based preparations. A comprehensive index was also developed based on physical , cooking , organoleptic and nutritional composition of selected rice varieties. Hybrid derivatives like Vyttila -3, Hraswa and remya were found to obtain high index scores among the seventeen varieties. Apart from these, traditional varieties like Veluthari Thavalakannan, Kutticheradi and Chuvannari Tavalakannan were also found to obtain high index scores. Hybrid derivatives such as bhadra, Nila, Jayanthi, Asha and traditional variety Kavungin Poothala were found to be least acceptable on the basis of index scores optained.ThesisItem Open Access Nutritional profile of middle-aged women of below poverty line (bpl) families with special reference to micronutrients(Kerala Agricultural University;Thiruvananthapuram, 2005) Anitha Chandran, C.; KAU; Chellammal, S.ThesisItem Open Access Utilization of jack fruit (Artocarpus heterophyllus Lam.) for product development and by-product recovery(Kerala Agricultural University;Thiruvananthapuram, 2005) Pandey, Shruti; KAU; Ukkuru, P.
