    Standardisation and acceptability of dairy products with cocoa mass
    (Department of Home Science, College of Horticulture, Vellanikkara, 2002) Sunita, Nair; KAU; Usha, V
    Standardisation and acceptability of dairy products namely milk chocolate, burfi, fudge, biscuits and ice cream were conducted by incorporating cocoa mass at 5 per cent and 10 per cent levels. The cocoa beans were roasted for 5 minutes and 10 minutes Shelf life of cocoa mass for three months was also assessed under ambient conditions. The results of the study indicated that the cocoa mass which was initially a powder got clumped by the third month and was insoluble in warm water. The microbial count and peroxide values in cocoa mass increased gradually for both 5 minutes and 10 minutes roasting and recorded highest during the third month. Comparatively cocoa mass made by 10 minutes roasting had significantly low microbial count and peroxide value. The sensory evaluation of milk chocolate showed the products incorporated with cocoa mass at 5 per cent level were more acceptable. Ten per cent level was acceptable if the cocoa beans were roasted for 5 minutes The sensory evaluation of burfi showed 5 per cent level of incorporation of cocoa mass to be more acceptable. Five per cent level and roasted for 5 minutes were found to have optimum scores. Ten minute roasting with 10 per cent incorporation of cocoa mass made the product bitter and flowy. The sensory evaluation of fudge showed that there was a significant decrease in the Period mean of acceptability of texture and taste of fudge by the third month, thus 5 per cent incorporation of cocoa mass with cocoa beans roasted for 5 minutes was found to have the highest acceptability. The Period mean of taste of biscuit increased upto the second month. During the third month significant decrease was observed. Five per cent level incorporation of cocoa mass was more acceptable. The taste of ice cream showed a significant decrease in Period mean by the third month. Five per cent level incorporation of cocoa mass was. found to have better acceptance in all criterias. Thus it was observed that 10 per cent level of cocoa mass incorporation hich was roasted for 10 minutes, resulted in least acceptable products. If the cocoa beans were roasted for 5 minutes, it was better accepted. All the products were found to be highly acceptable at 5 per cent level incorporation of cocoa mass especially 5 minutes roasting gave a better result. All the five products were more acceptable by the panel members selected from college going students.

    Dietary antioxidants and lipid profile of smokers
    (Department of Home Science, College of Agriculture, Vellayani, 2002) Prethi, N R; KAU; Nandini, P V
    The study entitled 'Dietary antioxidants and lipid profile of smokers' comprises information on the influence of various socio - economic and dietary profiles, as well as smoking habits on the health profile of selected respondents. The study was conducted among 100 adult males, who used more than 10 cigarettes a day and were in the habit of smoking for at least the past 10 years. Analysis of the smoking habit of respondents revealed that more than 50 per cent of the respondents were in the habit of smoking 10 to 15 cigarettes a day, while 14 per cent smoked more than 30 cigarettes a day. More number of them had been smoking for the past 10 to 15 years. The socio-economic profile of the smokers indicated that most of the respondents were in the age group of 36 to 40 years. Majority of the respondents were having an educational status of high school level. The occupational distribution of the respondents were more or less the same. Most of the respondents were married and were residing in nuclear families with four members. Majority of the respondents surveyed were having a monthly income between Rs. 2501 to 5000 On assessing the frequency of use of antioxidant rich food items. most of them used foods like milk and fats and oi Is most frequently while the least popular foods were flesh foods. Assessment of the influence of Smoking Index (SI) developed upon the various variables revealed that socio-economic profile and anthropometry has a strong influence on SI. Influence of SI on the anthropometry revealed significant negative correlation with MUAC, TST and weight, whereas no particular influence of a SI observed on the dietary pattern. Analysis of data pertaining to actual food intake revealed that the diets of respondents were inadequate and insufficient except for roots and tubers and milk. Nutrient intake of the respondents also did not meet the RDA specifications especially calorie, protein, iron and vitamin A. The serum analysis of the respondents revealed that smokers have reduced levels of serum antioxidants and elevated levels of serum lipid profile, when compared with normal standards. Assessment of the influence of different food groups upon the serum anti oxidant and lipid profile revealed that consumption of antioxidant rich foods not only helps to Improve the serum antioxidant profile but also helps to control the serum lipid profile. Frequent consumption of fat rich foods were found to increase the serum lipid profile. Frequent consumption of fat rich foods were found to increase the serum lipid profile while not influencing the serum antioxidant constituents. Data regarding the association between the serum profile and SI of the respondents revealed a significant positive association with total cholesterol and triglycerides.

    Learning disabilities in malnourished children
    (Department of Home Science, College of Agriculture, Vellayani, 2001) Sandhya, Chandran; KAU; Syamakumari, S
    The study entitled "Learning Disabilities in Malnourished Children" undertaken in the rural areas of Trivandrum district was conducted to study the relative effect of malnutrition on the learning disabilities of children between five to ten years. The study was carried out in Trivandrum district among children between five to ten years selected from three Lower Primary Schools, a Primary Health Centre and Institute of Rehabilitation of children with Cognitive and Communication Disorders (IRCCCD), a sister concern of Sree Chithra Thirunal Hospital.

The variables selected for the study were grouped into dependent and independent ones for convenience of statistical analysis. The dependent variables in the study included. the assessment scores of LD. nutritional s t a t u s , intelligence and overall development. While the independent ones consisted of those regarding demographic. socio-economic, developmental, health and nutritional as well as dietary aspects.Zo2.. The results in course of this investigation revealed the following salient findings. i) The demographic and socio economic status of the subjects studied revealed a heterogenous group of rural population ranging from low to middle. socio-economic background with random representation of the th~ee religions viz, Hindu, Christian and Muslim and predominently from backward caste. ii) The health and developmental history showed comparatively high prevalence of low birth weight, premature babies to lesser duration of breast feeding and with higher incidences of illnesses, developmental and behavioural problems, among the groups comprised of low rankers (Group Ill), malnourished (Group IV) and learning disabled subjects (Gro¥p V).
