摘要: 本实验以10%的蛋清蛋白溶液为研究对象,采用动态超高压均质处理,研究蛋清蛋白溶液平均粒度和流变性的变化。研究表明,10%的蛋清蛋白溶液的平均粒度随着压力的增加而出现明显减小的现象,其经过超高压均质后,由非牛顿流体的胀塑性流体转变为假塑性流体,均质后的蛋清蛋白溶液的表观黏度明显升高。

Abstract: This experiment dealed with the effects of microfluidization on the mean particle size and the rheological properties of egg white solutions (10%). The results indicated that: There are pronounced decrease of mean particle sizing following the increase of the pressure. Microfluidization induces the change from dilatant flow to pseudoplastic flow of non-Newtonian flow. The pronounced increase of apparent viscosity of egg white protein solution were observed after high pressure treatment.

Key words: microfluidization, high pressure, egg white protein, particle size, rheological properties, apparent viscosity
