Abstract

A comparison of the effectiveness of two procedures, ammonium sulfate fractionation and concanavalin A affinity (Con A) chromatography, for the purification of β‐conglycinin from soy flour was made. In addition, the effect of toasting on the effectiveness of these two procedures for purifying β‐conglycinin was studied. Results indicated that Con A affinity chromatography was less effective than the ammonium sulfate fractionation for the purification of β‐conglycinin. The ammonium sulfate fractionation produced nearly homogeneous β‐conglycinin; however, the yield from this procedure was very low (4.1%). Toasting the soy flour decreased the purification effectiveness of both procedures.
