摘要 探讨了蛋白质与脂类物质在油-水及气-水界面上的物理化学特性及分子间的交互作用。蛋白质与脂类在油-水及气-水界面上表现出不同的界面特性,一些小分子乳化剂等脂类物质在界面上能够降低界面张力,达到良好的乳化效果。蛋白质在界面上形成一粘弹性的网络结构,从而能够稳定乳浊液。当蛋白质与小分子乳化剂等脂类共存时,发生竞争性吸附和合作吸附两种作用,溶液体系中其它溶质的特性及蛋白质与脂类在溶液中的比率等因素决定这两种分子发生交互作用的类型。 This paper discuss the interfacial properties of protein and lipids (especially small molecular emulsifier ) and the molecular interaction. Protein and lipid show different interfacial properties such as surface rheology, diagram, adsorption etc. Protein and lipids perform competitive adsorption and cooperative adsorption in interface, resulting in food emulsion and foam instability or stability.
