采用细胞浸渍/扫描电镜（cell-maceration/SEM）方法，结合虹鳟鱼、黄尾鱼和河豚鱼肌肉断裂强度的测定，研究了胶原纤维网络的三维结构。虹鳟鱼和黄尾鱼肌肉在贮藏过程中发生了嫩化，而河豚鱼肌肉在贮藏72 h后仍没有发生嫩化。组织学观察表明，虹鳟鱼和黄尾鱼肌肉在贮藏24 h后，细胞周结缔组织厚度变薄，胶原原纤维密度降低。在72 h的贮藏过程中，未观察到肌肉结构的变化。这些结果表明，胶原纤维网络的结构变化与死后的嫩化过程相一致。这一结果与以前的光学显微镜和透射电子显微镜观察结果一致。
The three-dimensional structure of a collagen fibrillar network was examined by using a cell-macer ation/SEM method combined with measuring the breaking strength of rainbow trout, yellowtail, and tiger puffer muscles. Rainbow trout and yellowtail muscles were tenderized during storage, but tiger puffer muscle showed no tenderization even after 72 h storage. According to histological observations, the thickness of pericellular connective tissue in rainbow trout and yellowtail muscles became thinner, and the density of their collagenous fibrils decreased during 24 h storage. On the other hand, no struc tural change was observed during 72 h storage in tiger puffer muscle. These results showed that the struc tural change in the collagen fibrillar network corresponded to the post-mortem tenderization. This result agreed well with previous light microscope and transmission electron microscope observations.
