摘要: 采用动态超高压微射流均质机对大豆分离蛋白进行处理,研究了不同的压力对大豆分离蛋白起泡性、凝胶性的影响。结果表明动态超高压微射流处理能使大豆分离蛋白的起泡性、凝胶性得到改善,随着均质压力的逐渐增加,都有不同程度的提高,100ml的6%大豆分离蛋白经高速分散搅打后,泡沫高度可以达到180ml,16%的大豆分离蛋白凝胶强度可以达到0.08355kg。

Abstract: Soy protein isolate (SPI) was treated with dynamic high-pressure microfluidizer, the effects of foaming and gelation were studied by different pressure. As a result, dynamic high-pressure microfluidization treatment can improve the foaming and gelation properties, with the pressure increase, they were enhanced by different extent. The foam height of 100ml 6% soy protein isolate could reach 180ml after blending, the gel intensity of 16% soy protein isolation could reach 0.08355kg.
