摘要: 本文用扫描电镜(SEM)和透射电镜(TEM)对凝固型酸奶的凝胶体的超微结构进行了观察。酸凝乳凝胶的超微结构呈一种纤维网状立体结构,网状纤维中间形成无数有规则的空隙。空隙呈有规则的六棱形。凝胶体纤维网状立体结构的支架是由变性酪蛋白颗粒堆积形成。脂肪球和乳酸菌镶嵌于凝胶体纤维网中。

Abstract: The ultrastructure of yoghourt was investigated with SEM and TEM. The ultrastructure of yoghourt gel showeditself a tridimensional fibronet structure. There were a large number of regular holes in the fibronet of regular hexagon shape. Thetridimensional fibronet structure was supported by denatured casein granules. The fat globules and lactobacilli were inlaid in thetridimensional fibronet structure.
