| dc.description.abstract | Maize is an important cereal crop in the world providing nutrition to millions of people. In recent times, Maize cultivation is improving in our country with the release of number of varieties and hybrids. An investigation was undertaken in the department of Biotechnology, University of Agricultural Sciences, Bangalore to evaluate the physico chemical properties, biochemical composition and nutritional qualities of four selected Maize varieties viz., NAC-6002, NAC-6004, Hema and Nithyashree. Carbohydrate was calculated by difference and calorific value was computed using Atwater constants. Trace minerals were estimated by Flame photometry. Color was estimated using Hunter lab color difference meter. In vitro protein and starch digestibility were estimated. Protein fractions and β-carotene were estimated. Physical characteristics of grains, physico-chemical and functional properties of flour was estimated. The investigation revealed variations in most of the parameters studied. Variation in size of the grain, weight and density was evident, NAC-6004 exhibited good cooking quality. None of the varieties was found suitable for popping. Oil absorption capacity was highest in NAC-6002 (110.95%) and hydration capacity was highest in Nithyashree (173%). The crude fat content varied from 3.51 to 4.75 per cent. Hema was found to be richest source of β-Carotene. In vitro protein digestibility was highest in Hema (64.18%) and least in NAC-6004 (55-56%). Osborn and Mendel method was found to be efficient in extracting protein fractions. Starch content varied between 49.80 to 53.55%, and amylose content varied between 24.605 to 30.7%. Starch digestibility was highest in Hema (67.05%) and least in NAC-6004 (56.68%). | en_US |
