Abstract: Six different legume samples were selected for the study. Legumes were dehusked, processed and used for further experiment. The husk percentage of greengram, bengalgram, blackgram, redgram, soy bean and dolichos was 6.16, 9.90, 6.30, 9.32, 8.40 and 17.2 respectively. The SDF in present study ranged from 1.08 to 12.82 per cent. IDF content was observed in the range of 63.01 to 77.61 per cent. The TDF ranged from 64.82 to 85.99 per cent. A significant difference between treated and untreated samples (P 0.05) in the TDF content of the seed coat samples was observed. Total phenols content of samples ranged from 0.013 to 0.510 per cent. The phytic acid content of seed coat samples in present study ranged from 1.13 to 4.13 g/100g. Highest solubility index was observed in acid treated samples (11.62 %) and lowest in alkali treated (7.32). Swelling power was highest in raw samples (5.93 %) than the treated samples. The highest water absorption capacity was observed to be 3.8 g/g in the raw blackgram and dolichos seed coat. Fat absorption capacity was observed to be highest in the raw samples (4.03 g/g) than the treated samples followed by acid treated (3.76 g/g). Results revealed that seed coats are rich source of fibre.
