| 摘 要： | 研究水溶性大豆多糖(SSPS)、羧甲基纤维素钠(CMC)和高酯果胶(HMP)在含乳饮料中的粒径分布和离心沉淀率。结果表明：在SSPS、CMC和HMP的质量分数大于0.3%时，酸性含乳饮料的体系开始趋于稳定，当HMP添加量为0.3%、SSPS和CMC的添加量分别为0.5%时，含乳饮料体系稳定性最好，而且粒径分析与离心沉淀率结果相一致。通过分析含乳饮料的粒径分布和离心沉淀率可以快速、准确的判断所添加稳定剂的含量在含乳饮料体系中应用的可行性。

| Abstract: | In this paper,particle size distribution and centrifugal sedimentation rate of water-soluble soybean polysaccharide(SSPS),sodium carboxymethyl cellulose(CMC) and high ester pectin(HMP) in milk beverage were studied.The results showed that the acidic milk beverage system exhibited an increased stability when the concentrations of SSPS,CMC and HMP were higher than 0.3%.The best stability of the acidic milk system was achieved when HMP,SSPS and CMC were added at 0.3%,0.5% and 0.5%,respectively.Meanwhile,partic... |
