Item Developing value added and diversified products from coconut(cocos nucifera L)(Department of Home Science, College of Agriculture, Vellayani, 2004) Neelofar Illiaskutty; Mary Ukkuru, PItem Documentation and quality evaluation of selected traditional foods of central zone of Kerela(Department of Home Science, College of Horticulture, Vellanikkara, 2009) Aneena, E R; Indira, VThe study entitled “Documentation and quality evaluation of traditional foods of central zone of Kerala” was taken up with the objectives of identifying and collecting information on the various traditional foods of central zone of Kerala and documenting their mode of processing, and evaluating quality characteristics of the selected less used traditional foods. The study was conducted in four districts namely Eranakualm, Thrissur, Palakkad and Malappuram comprising the central zone of Kerala. Senior citizens who possess the details of traditional food items and preparations in each locality were selected as the respondents. The respondents were categorised based on the communities they represent. Details of traditional food habits with respect to preference for traditional foods, the reasons for the preference, frequency of preparation of traditional foods, traditional foods prepared during special occasions, festivals/rituals and during physiological conditions and traditional foods included for breakfast, lunch, dinner, and snacks were collected from the selected respondents. Transition that occurred in the traditional food pattern and in the preparation of traditional foods was also collected. Quality evaluation of selected traditional foods was conducted at laboratory level with respect to chemical constituents, acceptability and microbial growth. The foods were packed in suitable packaging materials and stored under different conditions and the quality evaluation of foods was carried out during storage. Majority of the respondents preferred traditional foods due to their health benefits and palatability. Most of the respondents prepared traditional foods for break fast and lunch and also prepared different traditional snack items. Most of the respondents did not prepare traditional health foods at home due to the laborious procedure involved in the preparation and the commercial availability of these products. Respondents belonging to different communities prepared various traditional foods during special occasions, festivals/rituals and consumed traditional foods during different physiological conditions. Most of the respondents included traditional food items for breakfast and lunch. Changes were observed in the traditional food pattern and traditional foods over different years with respect to ingredients, method of preparation and vessels/ utensils used for preparation. The recent trend of food consumerism was portrayed by the increased frequency of eating out habits, purchase of instant mixes and bakery items. From the traditional food items collected, twelve traditional foods namely inderiyappam, kala kala, kaliyadakka, karinellikka, madhura puttu, manda, muttayappam, niracha pathiri, paniyaram, poruvelangai, rankayyan and vishu katta and three beverages namely, cherunaranga then vellam, inji paneeyam and paanakam which were least used, nutritionally viable and organoleptically acceptable were selected and replicated under laboratory level. Quality evaluation of these foods was conducted initially and during storage. Evaluation of the chemical composition of the traditional foods showed that most of the traditional foods are rich in certain macro and micro nutrients. Organoleptic evaluation of the replicated foods indicated that most of the traditional foods were acceptable to the younger generation. The replicated traditional foods were packed in suitable packaging materials and stored under ambient or ambient and refrigerated conditions for different intervals. Among the different replicated foods inderiyappam, muttayappam, niracha pathiri, rankayyan and vishu katta were highly perishable and could be stored only for a day. The quality attributes of paanakam, cherunaranga then vellam and inji paneeyam also decreased considerably during storage. From the present study, it was found that the selected traditional food items could be replicated under the prevailing conditions without change in their quality aspects. Hence, these technologies should be popularised as an attempt to conserve the traditional cuisines of Kerala.Item Phytochemical analysis and antioxidant potential of banana (Musa spp)(Department of Home Science, College of Agriculture, Vellayani, 2016) Siji, S; Nandini, P VItem Developing baked and confectionery products based on sweet potato(Department of Home Science, College of Agriculture, Vellayani, 1999) Elizabeth Augustine; 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.Item Qualitative and quantitative changes in stored rice(Department of Home Science, College of Agriculture, Vellayani, 1995) Geetha, Roy; 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.Item 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; 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.Item Utilization of jack fruit (antocarpus heterophyllus lam.) for product development and by- product recovery(Department of Home Science, College of Agriculture, Vellayani, 2005) Shruti Pandey; Marry Ukkru, PItem Nutritional profile of middle aged women of below poverty line (BPL) families with special reference to micronutrients(Department of Home Science, College of Agriculture, Vellayani, 2005) Anitha Chandran, C; Chellammal, SItem Food preference and dietary habits of adolescents among agricultural laboures(Department of Home Science, College of Agriculture, Vellayani, 1993) Mony Paul, E; Mary UkkuruA study entitled food preference and dietary habits of adolescents among agricultural labourers families was undertaken to assess the socio economic personal characteristics food consumption pattern food preferences and the nutritional status of adolescents boys and girls. Majority of the families surveyed belonged to Hindu community and were under privileged. The families were nuclear type with medium size. Father was the main bread winner and major share of the income was earned by the male member. The per capita income of majority of families were found to be between 100 to 200. All the surveyed adolescencts were found to be well educated. All of the surveyed adolescents were non vegetarian cereals, vegetables, roots and tubers, milk fish fats and oils , sugar and jiggery and spices were found to be high frequently used foods among the adolescents. Pulses and fruits were medium frequently used foods . Green leafy vegetables meat and egg were low frequently used foods among them. Cereal based preparation were liked by both adolescents boys and girls. They liked fried foods and sweet preparations. Adolescents most preferred foods were found to be egg, apple, grapes, plantain, sapota and cashew nuts and low preferred foods were ragi, raddish, bittergourd , ivy gourd, star gooseberry and watermelon. Food preference of adolescent boys and girls were not found to vary very much. Factors such as total income of the family, type and size of family, educational status of adolescents and their parents, and the influence of peers were not found to influence the food preferences of the studied adolescents. Consumption of cereals, and fish met above the recommended dietary allowances (RDA) and nutrients such as protein , energy thiamine and niacin was met above 90 percent of RDA in adolescent boys and girls apart from vitamin C in adolescent girls. Weight for age and height for age of the adolescents were below the NCHS standard as well as Indian standards. Anaemia, pigmentation of skin , dental caries were the most common clinical manifestations in both adolescent boys and girls. Normal haemoglobin level was observed only in negligible adolescents. Nutritional status of adolescent girls were found to be better than adolescent boys in the present study.Item Nutritional status and dietary habits of irulas of Attappady(Department of Home Science, College of Agriculture, Vellayani, 1993) Indira, V; Prema, LA study on the nutritional status and dietary habits of Irulas of Attappady was carried out among 180 families to assess the socio-economic and food consumption pattern of the tribal families and also to assess the nutritional status of the children between the age group of 5 to 15 years. The results of the study indicated that majority of the families were of nuclear type with an average family size of 4.73. Agriculture labour was the main occupation of the tribes and most of the families were below the poverty line. Housing conditions and personal hygiene of the families were found to be poor. Irula tribes in general, were habitually non-vegetarians. Major expenditure of the family income was incurred for food especially cereals. Diet was found to be monotonous with less variety. Two –meal-a-day pattern was the standard system followed by the families, which included cereals, fats and oils and spices and condiments. Boiling was the predominant cooking method followed by the Irula tribes. Gunny bags were used to store cereals and pulses. Tribal families followed certain food restrictions during illness and special food were not included either in the diet of pregnant of lactating women or in the diet of children. Prolonged breast feeding and late weaning was practiced by the Irula tribes. The nutritional status of the children between 5 to 15 years of age was deficient and it was revealed in the anthropometric measurements like height, weight, mid upper arm circumference and skinfold thickness. Food weighment survey revealed a deficient intake of all foods except cereals. The intake of most of the nutrients was low. Low to medium nutritional status was observed among most of the children and birth order of the boys was found to influence their nutritional status. Anaemia was the most important clinical symptom observed among children which was reflected in the biochemical examination of blood for haemoglobin RBC count and packed cell volume. Sickle cell anaemia and parasitic infestations were observed among the children. The respondents had a favourable attitude towards the developmental programme implemented by various agencies to improve their health status. However awareness about health and nutrition was found to be poor.
