Modification of barley foam-active protein by graft with monosaccharide
Using barley foam-active protein as raw material,the modified protein was prepared in heating. The optimal processing was investigated through orthogonal test,which led to the conclusion that the optimum graft reaction conditions were as follows:the weight ratio of glucose to protein 1∶2,pH 9.5,60 min would yield graft reaction products with DG was 23.89% and browning index was 0.179. Compared with unmodified sample,the foam-active protein developed excellent foaming properties. These results indicated that graft reaction could be used as an efficient method to improve functional properties of foam-active protein.
