Trypsin inhibitor (TI) levels in the crop seeds varied between 0.0 in Adansonia digitata
and 40.8 TIU/mg in Pterocarpus osun
. Efficiency of inactivation of TI by autoclaving ranged from 58.1% in Millettia thonningii
to 100% in Sesbania pachycarpa
and Lonchocarpus. sericeus
. It is concluded that the effect of heat treatment on TI varies with plant species and could be dependent on the structural formula of each TI.
