This research examined the effects of sodium hexametaphosphate on the physicochemical properties and the microstructure of the milk fat globule membrane (MFGM) after freezing. The particle size distribution showed that the peak of the MFGM in the controlled sample was higher than the peak in the frozen sample. The MFGM sample that contained the highest concentration of sodium hexametaphosphate displayed the highest peak. The MFGM samples with the highest concentrations of sodium hexametaphosphate were more stable than the samples with the lowest concentrations. Sodium dodecyl sulfate Polyacrylamide gel electrophoresis and scanning electron microscopy showed sizeable destruction of the MFGM after freezing.

六偏磷酸钠的添加对冷冻后液态奶中乳脂球膜（MFGM）的理化性质和微观结构的影响

这项研究检查了六偏磷酸钠对冷冻后乳脂球膜（MFGM）的理化性质和微观结构的影响。粒度分布表明，对照样品中MFGM的峰高于冷冻样品中的峰。含有最高浓度的六偏磷酸钠的MFGM样品显示出最高的峰。六偏磷酸钠浓度最高的MFGM样品比最低浓度的样品更稳定。十二烷基硫酸钠聚丙烯酰胺凝胶电泳和扫描电子显微镜显示，冷冻后MFGM受到相当大的破坏。
