摘要:

本实验用大豆分离蛋白模拟传统豆腐的凝胶形成过程,研究分子间作用力对大豆蛋白凝胶形成过程及质构特性的影响。结果表明,大豆蛋白凝胶的形成过程受多种分子间作用力的影响,其中静电作用、疏水相互作用和氢键对石膏凝固大豆蛋白凝胶的形成具有重要的影响。

关键词: 分子间作用力, 大豆蛋白, 凝胶, 质构特性

Abstract:

Soy protein isolate (SPI) and plaster were used to mimic the gelation of traditional tofu to investigate the effects of intermolecular forces on formation and texture properties of soy protein gels. The results showed that the formation of soy protein gel is influenced by multifarious intermolecular forces and electrostatic forces, and hydrophobic interactions and hydrogen bonds make predominant contributions to the gelation of SPI induced by plaster addition.

Key words: intermolecular forces, soy protein, gelation, texture properties
