ThesisItem Open Access Value addition and quality evaluation of holy basil (Ocimum tenuiflorum L.)(Department of Community Science, College of Agriculture , Vellanikkara, 2023-01-25) Gayathri ,M; Gayathri, M; KAUHoly basil is the most renowned medicinal herb and is known as the mother of necessities for its infinite therapeutic benefits. It is referred to as the "Queen of Herbs," and the Sanskrit word "tulsi" means "incomparable." It is one of the oldest herbs in the Lamiaceae family and is widely cultivated throughout the subcontinent. The physicochemical composition of the holy basil accession (KAU-OC25) (IC-0640854) used in this research had a moisture content of 89.4%, and the levels of the macronutrients, protein and fat per 100 g were found to be 2.99 g and 0.61 g, respectively. It was revealed that the herb had a crude fibre content of 10.48 g/100 g. In terms of vitamin content, ascorbic acid was found to be 30.4 mg/g, and the amount of beta carotene was 2826.92 µg/100 g. In 100g of the sample, the holy basil contained 26.9 mg of calcium, 28 mg of iron, 4.2 mg of zinc, and 224 mg of phosphorus, respectively. The total flavonoid and phenol levels were 41.41 mg QE (quercetin equivalent) and 66.66 mg GAE (gallic acid equivalent) respectively. Holy basil has phytate, oxalate, and tannin concentrations of 3.99 mg/100 g, 2.33 mg/100 g, and 9.74 mg/100 g, respectively. The phytochemical makeup of the herb was analysed through chromatographical tools like O-HRLCMS and GCMS/Ms. The analysis revealed thirty eight medicinally active bioactive compounds namely eugenol, methyl eugenol, kaempferol, scutellarin, rosmarinic acid, luteolin, ursolic acid, vicenin, apigenin 7-O-glucuronide, genistein 4-O- glucuronide, betaine, ϒ- aminobutyric acid (GABA), fisetin, orientin, choline, DL-stachydrine, oleanolic acid, luteolin-7-Oglucuronide, baicalin, β-caryophyllene, ostruthin, hexadecanoic acid, 5 amino pentanoic acid, taxifolin, alpha-pinene, alpha-terpineol, chavicol, alpha cubabene, eucalyptol, estragole, alpha-caryophyllene, alpha-bisabolol, beta-ocimene, terpinene-4-ol and trans-4-thujanol and carvacrol. Eugenol has a number of protective qualities against a variety of conditions that can be fatal, including cancer, oxidative stress, inflammation, hyperglycemia, and elevated cholesterol. Kaempferol and scutellarin are powerful antioxidant flavonoids while rosmarinic acid is known to be effective against microorganisms like the herpes simplex virus. Luteolin and ursolic acid were reported to have potent anti-cancer properties. The active flavonoid derivative apigenin-7-O-D-glucuronide has a variety of pharmacological properties, such as antioxidant, anti-complement, and aldose reductase inhibitory properties. Fisetin, ursolic acid and oleanolic acid have proven anti-cancer activities. ϒaminobutyric acid (GABA) has a number of physiological effects, including lowering blood pressure, boosting immunity, improving cognitive function, inhibiting the proliferation of cancer cells, and reducing sleeplessness. The flavonol taxifolin exhibits strong antioxidant, reducing, radical-scavenging, and metal chelating properties. Anti-oxidative and anti-inflammatory activities are demonstrated by luteolin-7-O-glucuronide. Baicalin significantly reduces the replication of HIV 1. Carvacrol is a potent antioxidant and a great adaptogen to treat hepatic stress. Alpha-pinene, alpha-terpineol, estragole, alpha-caryophyllene and alpha-bisabolol had potent anti-inflammatory activity whereas beta-ocimene, chavicol, terpinene-4-ol and trans-4-thujanol has proven antimicrobial activities. Docking studies of the compounds revealed that six compounds namely kaempferol, baicalin, luteolin, rosmarinic acid and eugenol can be considered for further studies regarding the treatment of type 2 diabetes mellitus and fourteen compounds namely scutellarin, vicenin, ursolic acid, genistein 4-O-glucuronide, betaine, taxifolin, apigenin 7-O-glucuronide, ϒ-aminobutyric acid (GABA), 5 amino pentanoic acid, kaempferol, baicalin, luteolin, rosmarinic acid and eugenol display noteworthy anti-covid action. The successfully docked compounds were tested for drug-likeness using ADMET analysis which revealed that rosmarinic acid, kaempferol, luteolin, and taxifolin can be regarded as potential drug candidates. A dose-dependent inhibition of MCF-7 cell growth was seen by the methanolic extract of holy basil with an IC50 value of 24.80 µg/mL thus establishing its antiproliferative activity. Considering the immense therapeutic abilities of holy basil, it was developed into hard candy lozenges with varying concentrations of holy basil (10%, 15%, 20%, 25%, 30% and 35%) ginger and amla extract. The organoleptic evaluation of the lozenges revealed that hard candy lozenges made with 30 % holy basil extract were more acceptable, owing to which the shelf life studies were done. The physicochemical evaluation of 100 g of the selected candy revealed that it had a moisture content of 2.78 per cent, protein content of 2.39 g, fat content of 0.67 g, ash content of 0.81 mg and energy content of 376.05 kcal. The moisture level of the candy increased but all other parameters, including protein, fat, ash content, and energy, were found to decrease throughout the three month storage period. The bacterial growth of the candy was seen to be within tolerable limits. Throughout the shelf-life period, no fungal or yeast growth was seen. Holy basil should be exploited endlessly for its restorative and curative properties. Currently, the herb is primarily used to make herbal tea and ayurvedic medicines. Apart from this, it can also be considered as a culinary herb, due to its potential natural antioxidant properties and its immense scope for development of value added products.ThesisItem Open Access Development and quality evaluation of a jackfruit based nutri flour(Department of Community Science, College of Agriculture, Vellanikkara, 2022) Soumya, P S; KAU; Suma, DivakarThe study entitled “Development and quality evaluation of a jackfruit based nutri flour” was carried out at the Department of Community Science, College of Agriculture, Vellayani, during the period 2018-2021. The main objectives of the study were to formulate and standardize a jackfruit based nutri flour comprised of all the edible parts of the fruit and to evaluate its qualities and invitro therapeutic efficacy. Jackfruit cv. Koozha and varikka based nutri flour was developed on the basis of glycemic index of the various parts of the fruit. Raw jack fruits (12 weeks maturity) were selected. Weight of bulbs, perigones, seeds, rind, core and testa were recorded separately to get the final yield, wet and dry weight, moisture percentage, processing loss and dry matter percentage of the product. The order of glycemic index of jackfruit parts were observed as KJRF˃ KJTF ˃VJTF ˃VJRF ˃ KJPF ˃ VJPF ˃KJCF ˃VJCF ˃ KJBF ˃KJSF ˃ VJBF ˃VJSF. The major flour was constituted with greater percentage of fruit parts with low glycaemic index (50 – 60 %) and 40 % was formed by other components in different proportions. Ten formulations of nutri flour and control were evaluated for their sensory qualities. For these three popular breakfast dishes like “puttu”, “ada” and “oratti” were developed. On the basis of analysis of mean scores of sensory parametersF9 was selected as the best combination. Among the three products based on overall acceptability scores ‘oratti’ was found to be more acceptable. Analysis of functional quality revealed that nutri flour had lower swelling power (7.65g), solubility (1.48%), water absorption capacity (4.36%) and bulk density (1.04g/ml) compared to jackfruit bulb flours. The proximate composition of carbohydrate (31.59 g/100g), protein (7.03g/100g), dietary fiber (13.58 g/100g) were significantly high in nutri flour compared with koozha and varikka bulb flours. The moisture content of nutri flour was lower (0.96%), than koozha jackfruit bulb flour and varikka jackfruit bulb flour (1.28% and 1.39%) respectively. The mineral content such as, total minerals (0.98g), calcium (114.32mg), phosphorus (47.92mg), sodium (10.21mg), potassium (418.10mg), iron (1.67mg), manganese (1.59mg), copper (0.457mg) and zinc (0.923mg) content were higher in nutri flour in comparison to koozha and varikka jackfruit bulb flours. The nutraceutical components like phenol (3.03mg) phytic acid (166.77mg), tannin (19.45mg), β carotene (65.98 μg) and antioxidant content (35.85 μg) was significantly higher in nutri flour compare to koozha and varikka jack bulb flours. The developed jackfruit nutri flour formulation (F9) was packed in metallised laminated pouches and kept for storage studies under ambient conditions for a period of six months storage. During the storage period moisture content, microbial profile and organoleptic qualities were found to be acceptable. To reduce the level of oligosaccharides and to increase the starch digestibility the flour was fermented with Saccharomyces cerevisiae @ 5g/kg for 8hrs. In HPLC analysis, at a retention time of 6.93 minutes standard stachyose, untreated and treated nutri flour. Nutri flour treated with Saccharomyces cerevisiae @ 8 hrs was found to be low in oligosaccharides compared to control. In vitro starch digestibility was significantly high in yeast treated nutri flour (82.81%) when compared to untreated nutri flour (54.84%). Anti-diabetic activity of nutri flour was investigated through α-glucosidase and α-amylase inhibitory activity, by using different solvents. A maximum inhibitory activity was observed in petroleum ether extracted of nutri flour at a concentration of 100 μg/mL in α -amylase (47.17%) and α -Glucosidase (63.93%) enzymes. Hypolipidemic activity of nutri flour showed, highest inhibition percentage with petroleum ether (78.06%) and lowest with distilled water (39.53%). Hepato protective effect of nutri flour was higher in cells treated at 50% concentration. From the above study, it can be concluded that jackfruit based nutri mix has hypoglycemic, hypolipidemic as well as hepatoprotective properties. The nutri mix is formulated from all edible parts of jackfruit, which adds on to the therapeutic value of the product. The entire fruit utilization answers the answers the problem of environmental contamination with these underutilized fruit parts.ThesisItem Open Access Nutritional status of women engaged in the coir industry(Department of Home Science, College of Agriculture, Vellayani, 1996) Lovely, Ranganath; KAU; Vimalakumari, N KThe study entitled Nutritional status of women engaged in the coir industry was carried out of assess the nutritional status of women engaged in the spinning of coir yarn and to find out its influence on the work output, which in turn could affect their socio economic status. For the evaluation of nutritional status, the study was conducted in two levels – on a macro sample of 200 coir workers and on a microsample of 40 women coir workers. Details of the socio economic survey showed that the majority of families were small nuclear type, headed by male members following Hinduism. The main occupation of the community was coir work and in all the families at least one woman was employed in a coir cooperative society in the vicinity. Many of the families had a monthly income that ranged between Rs.1000 to 2000. Lack of permanent and full time employment, high cost of living , inability to educate their children, problems related to economic burdens imposed by repayment of loans and medical expenses, lack of housing facilities and absence of male earning members in the family were the important economic problems, in the order of priority, as felt by the families, which have led them to a life of miserable existence. Their poor socio-economic background is reflected the fact that the physical amentities available to the coir worker’s household left much to be desired. All the families were found to be poverty stricken when the Rural Quality of life Index (RQLI) was calculated. The families suffered from household food insecurity that their diets were ill balanced and were deficient with respect to pulses, egg, meat, green leafy vegetables and fruits. The poverty and poor food intake by the families were reflected in the socio economic characteristics and low nutritional status of the women coir workers though they were wage earners. The poor nutritional status is reflected in their poor stature which was suggestive of low food intake and dual responsibilities of the household as well as of the work site. Apart from this the dietary inadequacy was reflected in wide prevalence of anaemia among 85.00 per cent of the respondents, from the microsample, which was found to influence their work output. The work output and nutritional status which are interrelated seemed to be further influenced by the poor working conditions, absence of physical amenities, poor food intake insanitary conditions and consequent parasitic infections and infestations. However, it is gratifying to note that occupational disorders were not prevalent to an extent that merits mention. The coir workers when spin the golden yarns of the economic and social fabric of the state of Kerala, the land of palms, re found to be tredding through a path of poverty and food insecurity leading them to poor nutritional and health status. This makes them a vulnerable lot needing economical social support from the rest of the population and from the Government, through a multidimensional approach, so that they may have better health and nutritional status so as to become the torch bearers of our heritage, who may boost our economy paving way to healthy descendants.ThesisItem Open Access Formulating fermented cassava food products Subtitle: standardisation of garl(Department of Home Science, College of Agriculture, Vellayani, 1989) Sathya, lakshmi C.; Chellammal, SThesisItem 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 Developing baked and confectionery products based on sweet potato(Department of Home Science, College of Agriculture, Vellayani, 1999) Elizabeth, Augustine; KAU; Chellammal, SA study on ‘Developing baked and confectionery products based on sweet potato' was conducted with major objective to develop value added baked and confectionery products based on sweet potato flour. The study comprised of standardisation of raw materials, product development, assessing nutritional significance, organoleptic quality studies, preference tests and shelf life studies. The five baked and five confectionery products was formulated with sweet potato flour as the basic ingredient. Three combinations were tried with different proportions of sweet potato flour. The other ingredients added to sweet potato flour were maida, egg, sugar, ghee and skimmed milk powder. The selection of best combination was based on amino acid scores chemical scores and cost benefit ratio. A combination with 50 per cent sweet potato flour and 50 per cent maida was selected as the ideal combination, since it secured higher amino acid score and chemical score. The cost of the combination was also found to be satisfactory. The nutritional composition of the food product revealed that the product contained all the nutrients in optimum quantity. The nutritional quality of the developed food products after processing with reference to calories, proteins, β carotene, calcium, phosphorous and zinc were determined through suitable laboratory techniques. ISI type tests specified to such products were administered to the developed foods and the values were comparable with ISI specification. Organoleptic studies of the developed food products was assessed by two groups of consumers viz., college students and technical experts. The parameters tested were appearance, colour, flavour, texture and taste. The analysis revealed that both the baked and confectionery products got highest scores. Baked products had a slightly higher mean score, compared to confectionary products. In the preference tests of the developed products conducted among farm women of Venganoor, Srikariyam and Kaliyoor panchayath and entrepreneurs in Thiruvananthapuram city were also showed the same result. Moisture and insect infestation were-lower in flour stored in glass and plastic containers. Effect of storage on moisture and over all acceptability were revealed that there was an increase in moisture content during the fourth week of storage period. There was an increase in moisture during storage and the difference was statistically significant. The overall acceptability was found to be decreased after storage. There was no insect infestation in the developed products during the storage period. The assessment of microbiological quality revealed that all the products were attacked by different types of microorganisms. The result of the present study suggest that new methods of processing could be introduced to add value to the crop and it is possible to develop different types of processed products based on sweet potato products which may result in increased consumption of tuber in the future and also for building up a healthy rural population.ThesisItem Open Access Food consumption pattern of rural house-holds below poverty line as influenced by food subsidies distributed through fair price shops(Department of Home Science, College of Agriculture,Vellayani, 1994) Priya Gopinath R; KAU; Prema LA Study on the food consumption pattern of rural household below poverty line as influenced by the food subsides distributed through fair prices shops was taken up to evaluate the socio – economic and personal characteristic of the beneficiaries, daily food consumption pattern and contribution of food subsidies available through fair price shops on their daily diet. On the basis of their participation in public distribution system 120 households of 4 groups with 76 to 100 percent participation , 51 to 75 percent participation , 26 to 50 percent participation and less than 25 percent participation were selected for the study. All the house holds surveyed were more or less in similar socio economic back ground. Present of the monthly income in all the four groups was incurred for food especially for cereals. It was also found that percentage cereal expenditure was increasing from group 1 to group4. Among the house holds in the four groups more percentage of house holds were spending less than ten percent of their total food expenditure for purchasing food ration. A comparison among four groups revealed that percentage of ration expenditure against total food expenditure was low in group 1 and this was gradually increasing from 1 to group 4. All households in the four groups were found to include rice, sugar, coconut, milk, spices and condiments and oil every day. Rice , wheat, sugar and oil were purchased from fair price shops. Rice and oil distributed through this shops were not adequate for the households and hence open marker services were utilized. House holds under groups 1 were found using the ration cards regularly in every week and households in group 4 were not in the habit of purchasing ration regularly. The beneficiaries had favourable views about the quantity and quality of food subsidies supplied through this system. Food consumption pattern of all households in 4 groups in revealed that the food consumption of households were better in group 1 than the house holds in other 3 groups. But the diets of all the four groups were below the recommended daily allowances. Nutritional status of different age groups was ascertained in the 20households selected (10 each from group 1 and group 4). It was found that clinical scores based on various deficiency diseases was higher for family members belonging to group 2. Teethcarries and spongy bleeding of gums were common among the children of the two groups of the house holds. Haemoglobin level was below average in adult females and adolescent females in both the groups. The present study gives an indication that public distribution system has positively influenced the regular beneficiaries and prolonged implementation of the programme is one of the methods to achieve sufficient health profile for the population in below poverty line of the country.ThesisItem Open Access Qualitative and quantitative changes in stored rice(Department of Home Science, College of Agriculture, Vellayani, 1995) Geetha, Roy; KAU; Prema, LQualitative and quantitative changes in stored rice varieties viz. PTB – 10 and Red Thriveni were determined by assuming the changes in their grain constituents, physical characteristics, insect infestation, cooking characteristics and organoleptic qualities. After six months storage effect of different storage containers such as gunny bag, pathayam and metal bin on these qualities were taken into consideration. The grain constituents like protein, nonprotein nitrogen, calcium , iron and phosphorous were found to decrease at a greater rate in PTB – 10 stored in gunny bag when compared to red thriveni. Similarly constituents like moisture, uric acid and freefatty acids were found to increase in PTB-10 than in red thriveni. Chnages in grain constituents, reducing sugars, nonreducing sugars, starch and amylose were observed both in raw as well as in cooked rice samples after storage. Increase in reducing sugar and amylose was at a greater rate in PTB-10 stored in gunny bag especially when cooked while nonreducing sugars and starch level were found to decrease in a similar order. Compared to PTB – 10 in gunny bag after storage, red Thriveni obtained lower values for thousand grain weight and total solid level, when stored in all the storage containers tried. Head rice yield and gelatinization temperature of rice samples increased in red thriveni after storage, the rate being higher in gunny bag when compared to other two storage structures. Viscosity was found to increase greatly in red thriveni stored in metal bin. Insect infestation was found to be greater in gunny bags while metal bin was found to be insect proof. PTB – 10 was affected by insects more when compared to Red thriveni. PTB-10 obtained higher values for cooking characteristics such as volume expansion and gruel loss than red thriveni, when stored in gunny bag. As as result of storage water uptake level and swelling index increased at a greater rate in red thriveni in all the storage containers tried. The rate of decrease in optimum cooking time was greater in PTB-10 stored in gunny bag while stickness was greatly reduced in red thriveni when compared to PTB-10. Raw rice samples were more acceptable before storage as quality parameter hardness increased after storage. Storage provided low scores for colour and odour which had a negative influence on consumer acceptance. Red Thriveni was more acceptable for all the quality attributes than PTB-10. The quality attributes colour and appearance obtained low scores in the two rice varieties the decrease being greater in PTB-10 than Red Thriveni. Taste, flavor and doneness was found to decrease in the two rice samples. The rate of decrease in taste. Flavor and doneness was lower in red thriveni when compared to PTB-10. Among the storage containers, metal bin was found to be a better storage structure than pathayam and gunny bag. The experiment threw light on the significant of metal bin as a storage structure and favourable facts in the shelf life qualities of evolved varieties like red thriveni.ThesisItem Open Access Quality parameters of certain pre-release cultures of rice developed at regiopnal agricultural research station,Pattambi(Department of Home Science, College of Agriculture, Vellayani, 1992) Neelofar, Illyaskutty; KAU; Prema, L“The quality parameters of certain pre – release cultures of rice developed at Regional Agricultural Research Station (RARS) Pattambi” were determined by assessing their nutritional composition, physical characteristics, cooking characteristic, as well as organoleptic qualities with Red Triveni as check. The effect of processing methods was also taken into consideration. The nutritional composition of pre – release rice cultures, with reference to calories, starch, protein, ash, calcium, phosphorus and iron were found to be high when compared to Red Triveni. The calorific value, and iron of the parboiled rice samples were also found to be higher. Among the physical characteristics all the pre – release rice cultures were observed to have low values for thousand grain weight and grain dimension, unlike for head rice yield and gelatinization temperature. A decrease on all the physical characteristics except thousand grain weight and head rice yield was observed in samples parboiled. Compared to Red Triveni pre – release rice cultures had obtained lower values for cooking characteristics such as optimum cooking time, elongation index, gruel loss and water uptake and higher value for elongation ratio, volume of expansion and amylose content. As a result of parboiling, optimum cooking time, and elongation ratio were found to increase and there was a decrease in elongation index, gruel loss, volume of expansion, water uptake, amylose content due to parboiling. The flour volume of all the pre – release rice cultures was comparatably high when compared to Red Triveni. Parboiled rice cultures had low flour yield when compared to raw cultures. The increase in batter yield after fermentation was more for Red Triveni when compared to the pre – release rice cultures. Acidity value for all the pre-release cultures were low when compared to Red Triveni. All the pre – release cultures were more acceptable as cooked rice (raw). Parboiling had a negative influence on cooked rice mainly because of less acceptable appearance and colour. Puttu was more acceptable for all the quality attributes in all the rice cultures including Red Triveni. Red Triveni was less acceptable because of its reddish colour. For idiappam, the quality attributes colour and appearance had obtained less score for Red Triveni, cultures 8770 and 871. Iddlimade from parboiled rice obtained lower score for the attributes colour, appearance and texture for all the cultures. Red Triveni had batter texture than all the cultures.
