Recently, soybean Bowman-Birk protease inhibitor (BBPI) has gained growing interest among researchers because of its chemopreventive activity that is closely related to its chymotrypsin inhibiting activity.

Bbpi Content of Soybeans Examined

In this study, BBPI content in domestic soybean cultivars and soybean products was investigated by enzymatic method and competitive ELISA method. The overall chymotrypsin inhibiting activity and BBPI contents were 8462-14797 U/g and 400-780 mg, respectively. The correlation coefficient between C.I.A. and BBPI contents was 0.838.

Bbpi Content Higher in Hyocotyl

The BBPI contents on the basis of weight were a little higher in the hypocotyl of soybean than that in the cotyledon.
