Bajaj, Malika
The effect of two processing treatments-soaking and pressure cooking on level of nutrients and antinutrientsin rice bean (Vigna umbellata) was Four Investigated types of rice bean (Vigna umbellata) viz., RBL-1, RBL-6, RBL-35 and RBL-50 were subjected to soaking (12h) and pressure cooking (15 min) and analyzed for proximate composition and antinutritional constituents. Significant per cent reduction was observed in content of phytic acid, trypsin inhibitor activity, polyphenols, saponins after soaking and pressure cooking, respectively. Soaking and pressure cooking, however, did not affect the protein, ash, fat and fiber content of rice bean varietiessignificantly. The use of domestic processing like soaking and pressure cooking significantly improved the nutritional composition by reducing the level of antinutrients to a great extent without affecting the other nutrients.
