摘  要:
凝胶性是蛋白质的主要功能特性之一,本文介绍蛋白质凝胶形成的机理,并对超高压条件下影响食品蛋白凝胶特性的主要因素包括压力、时间、蛋白的种类和浓度等进行分析,此外对超高压处理后蛋白凝胶的形成及其分子构象如三级结构中二硫键和疏水作用的改变以及二级结构中α-螺旋、β-折叠、无规则卷曲含量的变化进行深入阐述,进一步在此基础上提出相关领域未来的发展方向。

摘  要:
Gelatin is one of the major characteristics of protein.In this paper,formation mechanism of protein gel is introduced.Meanwhile,the effects of major factors as pressure,time,and protein type and protein concentration on protein gelatin in foods under ultra-high pressure conditions are explored.In addition,an in-depth description has been made on protein gel formation and its molecular conformation after ultra-pressure treatment,such as the changes of disulfide bonds and hydrophobic interactions in tertiary structure and changes of α-helix,β-folding and non-random crispation content in the secondary structure.Moreover,the directions for the future development are proposed.
