The trypsin-inhibitor activity was lowest in both acid treated and protein isolate of roasted guarmeal and highest in the raw guarmeal. In vitro protein digestibility of acid-treated and protein isolate of raw guarmeal was highest followed by acid-treated and protein isolates of roasted guarmeal as compared to raw or roasted guar-meal. However, lower levels of trypsin inhibitor activity improved the in-vivo protein digestibility in protein isolate and acid-treated of roasted guarmeal as well as roasted guarmeal. Raw guarmeal and its protein isolates were lethal in in-vivo system
