摘要
通过研究不同干燥方法(冷冻干燥和喷雾干燥)对SPC(大豆浓缩蛋白)的NSI(氮溶指数)、起泡性和乳化性的影响,并利用凝胶电泳和傅立叶红外光谱方法研究不同干燥方法对SPC结构的影响;探讨SPC功能性质改善的机理。
This paper studies the difference in NSI, emulsifying ability and foaming ability of SPC (Soy Protein Concentrate) after processing by different drying methods (spray drying and freeze drying). The structures of SPC were analyzed by electrophoresis and infra-red spectrum to study the mechanism for NSl increase and improvement in emulsifying ability and foaming ability of SPC,
