鱼糜微结构的几何描述及分析

Geometric Describing and Analysis on the Microstructure of Minced Fish

鱼糜流变特性的研究，可以为鱼糜加工机械的开发研制、鱼糜加工工艺的设计、加工生产过程中的监控等提供必要的理论依据鱼糜的微结构与其流变特性密切相关，鱼糜微结构的定量描述一直困扰着该研究领域的人们，因此，笔者用显微图像技术探讨了鲢鱼糜的微结构通过分析不同实验条件下鱼糜的微结构，得出可用鱼糜微结构中孔隙平均径。

The research on rheological behaviour of minced fish can provide the necessary theoretical bases for the processing machinery development,processing technique design and processing monitor of minced fish production. The structure of minced fish is relative to its rheological behaviour.The quantitative analysis of its structure confused people in the domain of its research. The minced fish microstructure was studied using micro-graph technology in this paper. Based on analysis of minced fish microstructure under different operating conditions(solid contents,processing time), it is found out that the average diameter and its cumulative distribution, the distance dimension between total mass center and the mass center of porous, could be used to describe the minced fish microstructure.
