title: Novel method using phytase for separating soybean beta-conglycinin and glycinin.
abstract: A novel method for separating soybean beta-conglycinin and glycinin from defatted soymilk by a phytase treatment was developed. Phytase was added to defatted soymilk (1000FYT/100 g of protein) at pH 6.0, and the mixture incubated for 1 h at 40 degrees C. This procedure separated beta-conglycinin and glycinin without needing a reducing agent or cooling into the soluble and insoluble fractions, respectively. Simultaneously, most of the phytate in both proteins was removed.
