焦糖色素的色率及红色指数与pH值关系的研究

Research of relation between color ratio and red index of caramel color and pH

通过测定焦糖色素的色率、红色指数在不同pH值下的变化 ,发现 :在pH 2 8～ 7 4范围内 ,焦糖色素的色率有一最低点 ,红色指数有一最高点 ,两个极值点均在pH 4 5～ 5 0。

Through test color ratio and red index of Caramel Color in different pH,we find that,there is a minimum color ratio and a maximum red index between pH 2 8～7 4,and the two extremum points are in pH 4 5～5 0
