Protease inhibitor activity in seed flour of local bean (Phaseolus vulgaris L.) cultivars

In the present study, nine Phaseolus vulgaris L. cultivars of Himalayan region were analyzed for trypsin and-amylase inhibitor activity. Trypsin inhibitor activity (TUI) per gram seed flour wasmaximumin Baspa cultivar (3100.833±2.674) and minimum in Luxmi cultivar (1026.250±4.070), while the total soluble protein(mg per gram seedflour) was maximum in Capsule cultivar (154.984±0.384) and minimum in Contender cultivar (105.034±0.408). α-Amylase instead activity (AIA) per gram seed flour was found maximum in Triloki cultivar and it was found to be 4.974±0.006, 10.257±0.016 and 8.170±0.014 respectively. The minimum α-amylase inhibitor activity per gram seed flour (2.211±0.015) was foundin Baspa cultivar.
