摘要: 研究了葡萄糖氧化酶(GOD)和溴酸钾对小麦粉蛋白中巯基的影响,同时测定了清蛋白、球蛋白、麦谷蛋白、麦胶蛋白提取率的变化及面筋蛋白中氨基酸的组成变化。结果表明,葡萄糖氧化酶对小麦粉中蛋白质的改性作用较溴酸钾速度快且作用强烈,同时,过量的葡萄糖氧化酶可能会造成氧化过度。

Abstract: The influence of the glucose oxidase (GOD) and potassium bromate on the -SH in wheat flour protein was studied. The variation of the extract content of albumin, globulin, gliadin, glutenin in wheat flour and the composition change of the amino acid in gluten protein was aslo investigated. The results indicated that compared with potassium bromate, GOD has a strong effect on denaturing the wheat flour protein and in addition, excessive GOD might result in overoxidation.
