Abstract

Trypsin and chymotrypsin inhibitor activities of defatted seed meals of akashmoni (Acacia auriculaeformis) and karanja (Pongamia glabra) were studied before and after detoxification. Protease inhibitor activities were significantly higher in the unprocessed seed meals when compared with the processed seed meals. Detoxification also improved the in vitro protein digestibilities of these seed meals significantly. Processed meals of these legume seeds, with lower protease inhibitor activities and higher protein digestibilities, could readily be used as animal feed.
