Nutritive profile which includes proximate principles and dietary fibre, water soluble and fat soluble vitamins, minerals and trace elements was analysed in rice (36 varieties), sorghum (36 varieties), pearl millet (5 varieties), small millet (6 varieties), wheat (38 varieties), maize (28 varieties). The average protein content, total ash and total fat content of the rice varieties were 10.76 g/100g, 0.74 g/100g and 1.16 g/100g respectively while total dietary fibre ranged from 2 (IIRR RBF-5) to 3.97 g/100g (IIRR RBF-17). Average protein content in sorghum was 12.48 g/100g while ash and total fat were 1.64 g/100g and 2.88 g/100g respectively. Total dietary fibre content of sorghum was 7.98 g/100g. The average protein content of pearl millet and small millet was found to be 12.46 g/100g and 13.55 g/100g respectively. The total dietary fibre content of rice and sorghum was comparatively lesser than that of pearl millet (10.03 g/100g), small millet (8.95 g/100g), wheat (10.19 g/100g) and maize (9.08 g/100g). The proximate principles and dietary fibre content was analysed.

 

Water soluble vitamins such as vitamin B5, B6 and B9 were analysed in all the 149 samples and reported in table 2. The highest vitamin B5 content in rice was found in IIRR RBF-13 (1.57 mg/100g) Sorghum AKSV-313 (1.05mg/100g) pearl millet; PHULE ANURADHA (1.15 mg/100g); small millet SIA-3088 (1.79 mg/100g); wheat BIO 16-10 (1.16 mg/100g);  maize HQPM-9 (1.21 mg/100g). The total vitamin B6 content of rice varieties were 0.030 to 0.69µg/100g; sorghum varieties were 0.106 to 0.235µg/100g, small millet 0.55 to 0.134 µg/100g; wheat 0.44-0.090µg/100g; maize 0.175-0.558 µg/100g. Average total folates (vitamin B9) of rice, sorghum, pearl millet, small millet, wheat and maize where 32.91 µg/100g, 34.35 µg/100g, 58.03 µg/100g, 61.91 µg/100g, 49.66 µg/100g and 42.13 µg/100g respectively.
