Abstract: A functional soybean acid-precipitated protein(SAPP)-polysaccharide conjugate was prepared by dry-heated storage at 60℃ and 79% relative humidity for 5 days, and various factors affecting the maillard reaction of SAPP-polysaccharide were studied in a series of experiments. The molecular structure features of SAPP and its conjugated dextran were analyzed through the UV-spectrums.

Key words: SAPP, emulsifying properties, maillard, dry-heating
