摘 要: 研究了不同相对分子质量的多元醇对大豆蛋白喷雾干燥的影响。结果表明:添加多元醇后喷雾干燥所得大豆蛋白的性质发生了明显变化;随着多元醇相对分子质量的增加,大豆蛋白的氮溶指数提高,乳化活性提高,粒径减小,热稳定性提高,热变性程度降低。 The effects of different relative molecular weight polyols on soy protein spray drying were studied. The results indicated that adding polyols could change the properties of spray - dried soy protein significantly; with the increase of the relative molecular weight of polyols, the nitrogen solubility index, emulsifying activity and thermal stability of the soy protein improved, but the radius and thermal denaturation of the soy protein reduced.
