| 摘 要： | 通过考察豆乳添加CaCl2后理化性质的变化,研究影响豆乳粉溶解性的因素.检测了豆乳粉的溶解性,并对豆乳中离子强度,粒子含量、大小,蛋白组成,豆乳中游离巯基及表面疏水性质变化进行了分析.结果表明:随着CaCl2浓度增加,所得豆乳粉分散性有所下降,但润湿时间极显著缩短;离子强度变化对豆乳粉溶解性未产生影响;加钙豆乳中粒子含量增加、粒径增大;而粒子的蛋白组成变化并未改变豆乳的游离巯基及表面疏水基团含量.因此,豆乳中粒子含量及粒径分布足影响豆乳粉溶解性的重要因素.

| Abstract: | Factors effecting solubility of soymilk powder was studied by investigating change of its physicochemical properties after adding CaCl2.The solubility of soymilk powder under different CaCl2 concentration was determined.The physicochemical characterizations of the soymilk,including ionic strength,particle content,particle size distribution,protein composition,free sulfhydryl group and hydrophobicity were also analyzed.With the increase of CaCl2 concentration,the dispersibility of the powder decreased,while ... |
