摘要: 大豆蛋白分子质量大、结构较紧密、油滴吸附速率较慢,因此乳化特性较低,不能满足其在现代食品加工中的应用需求。改善大豆蛋白的乳化特性成为目前的研究热点。本文综述了挤压预处理、酶解改性和挤压预处理联合酶解过程对大豆蛋白乳化特性作用的研究进展,并分析了大豆蛋白在不同改性过程中蛋白构象的变化、蛋白与蛋白之间的相互作用及乳化特性的改善情况,为研究挤压-酶解过程改善大豆蛋白乳化特性的机制及生产应用提供理论支撑。

Abstract: Soy protein has poor emulsification characteristics due to its large molecular mass, compact structure, and slow oil droplet adsorption rate, hindering its application in food processing. Therefore, improving the emulsifying properties of soy protein is becoming a research hotspot. This article reviews the latest progress in understanding the effect of extrusion pretreatment and/or enzymatic hydrolysis on improving the emulsifying properties of soy protein. The conformational changes of soy protein during the modification processes, the protein-protein interactions, and the improvement of emulsifying properties are analyzed. We believe that this review will provide theoretical support for exploring the mechanism by which extrusion combined with enzymatic hydrolysis can improve the emulsifying properties of soy protein and for its industrial application.

Key words: soybean protein isolate; extrusion pretreatment; enzymatic hydrolysis; extrusion combined with enzymatic hydrolysis; emulsification characteristics
