Irradiation inactivation of some antinutritional factors in plant seeds
1998
Abu-Tarboush, H.M.
Effects of gamma-irradiation (1.0-10 kGy) on trypsin, chymotrypsin, and alpha-amylase inhibitors of soybean and Moringa peregrina seeds on tannin of sorghum, gossypol of cottonseed, and in vitro digestibility of soybean were investigated. A dose of 10.0 kGy caused decreases in trypsin (by 34.9%) and chymotrypsin (by 71.4%) inhibitor activities in soybean defatted flour, whereas its in vitro digestibility increased from 79.8 to 84.2%. The alpha-amylase inhibitor activity of Al-Yassar (M. peregrina) was decreased by 43.6 and 47.8% upon treatment of 7.0 and 10.0 kGy, respectively. Doses of 10.0 and 7.0 kGy significantly reduced the tannin content in Shahlla sorghum but not in Hemaira sorghum. Total and free gossypol contents were slightly reduced by irradiation.
