摘　　要：大豆蛋白的多功能性是由其复杂的结构所决定的,对蛋白质改性的实质是进行蛋白质结构的调整,任何功能性的变化都是蛋白质结构改变的结果。提高大豆蛋白胶黏剂的耐水性能是改性研究的热点,利用Design-Expert软件,分析了响应面法优化十二烷基硫酸钠(SDS)-硼砂复合改性大豆分离蛋白胶黏剂的工艺条件,讨论了各因素对胶接强度等质量指标的交互影响,确定了最佳工艺条件:十二烷基硫酸钠加入量为大豆分离蛋白质量的0.7%,硼砂的质量为大豆分离蛋白质量的5%,反应温度55℃,耐水胶合强度为1.97MPa,并对优化结果进行了验证。The versatility of soybean protein is determined by its complicated structure. The essence of protein modification is adjustment of protein structure, any function changes are the result of a change in protein structure. Improving the water resistance of soy protein adhesives is a hotspot of research on modification. The response surface method optimization of sodium dodecyl sulfate （SDS）-borax compound modification process canditions for isolated soybean protein adhesives is analyzed by the Design-Expert software. The interaction effects of various factors on the quality indexes such as bonding strength are discussed. And the optimum technological conditions are confirmed as follows： the amount of sodium dodecyl sulfate is 0.7% of the isolated soybean protein mass, the mass of the borax is account for 5% of the isolated soybean protein mass, the reaction temperature is 55℃, and the water resistant bonding strength is 1.97MPa, and the optimization results are verified.
