Abstract

Millets have the potential to contribute to food security and nutrition, but still these are underutilized crops. The present study was undertaken with a view to analyse the physico-chemical, functional and nutritional composition of foxtail millet, barnyard millet and rice and to compare the sensory quality and nutritive value of food products from foxtail and barnyard millet with rice. Analysis of physico- chemical and functional characteristics revealed that the thousand kernel weight of foxtail millet, barnyard millet and rice was 2.5, 3.0 and 18.3xa0g, respectively and thousand kernel volume was 1.6, 13 2.0 and 7.1xa0ml, respectively. The water absorption capacity of foxtail millet, barnyard millet and rice was 1.90, 1.96 and 1.98xa0ml/g, respectively and water solubility index was 2.8, 1.2 and 1.0xa0%, respectively. Viscosity was measured for foxtail millet (1650.6 cps), barnyard millet (1581 cps) and rice (1668.3 cps). Analysis of nutritional composition showed that the moisture content of foxtail millet, barnyard millet and rice was 9.35, 11.93 and 11.91xa0%, respectively. The total ash, crude protein, crude fat, crude fibre and carbohydrate of foxtail millet were 3.10, 10.29, 3.06, 4.25 and 69.95xa0%, respectively, for barnyard millet were 4.27, 6.93, 2.02, 2.98 and 71.87xa0%, respectively and the corresponding values for rice were 0.59, 6.19, 0.53, 0.21 and 80.58xa0%, respectively. The energy value for foxtail millet, barnyard millet and rice was 349, 407 and 352xa0Kcal, respectively. The foxtail millet contained 30.10xa0mg/100xa0g calcium and 3.73xa0mg/100xa0g iron whereas barnyard millet contained 23.16xa0mg/100xa0g calcium and 6.91xa0mg/100xa0g iron. Values of 10xa0mg/100xa0g calcium and 0.10xa0mg/100xa0g iron were observed for rice. The formulated products viz. laddu, halwa and biryani from foxtail millet, barnyard millet and rice (control) were analysed for their sensory qualities. Among the products prepared, there was non significant difference with regard to the colour, flavor, texture, appearance and overall acceptability of foxtail and barnyard millet laddu and halwa when compared to control. Foxtail millet biryani was most acceptable compared to barnyard millet and control biryani. Nutritive value of formulated products was calculated and it was compared with the rice. The protein, fat and fibre content of the formulated products from foxtail and barnyard millet were higher than the rice products. Thus from the present study it was concluded that the foxtail millet and barnyard millet are superior in nutritive value to rice and have potential for use in traditional food products.
