Trypsin Inhibitor Activity in Soybean Seed as Influenced by Stage of its Development and Different Treatments, and the Distribution in its Anatomical Parts

Proteinase inhibitors are widely distributed in plants and food crops and their association in grain legumes in particular is well recognised. The distribution of trypsin inhibitor in plant parts is reported to vary from crop to crop. Halim et al showed that endosperm of corn contained higher level of trypsin inhibitor than the embryo. Others have suggested that soybean trypsin inhibitor is one of the factors responsible for the poor utilisation of its protein in the raw state.
