摘　　要：采用紫外可见分光光度法研究了双氧水对杨梅红色素的褪色试验。对双氧水用量、溶液pH、褪色温度及时间进行了探索。在1 mol/L H_2O_2用量7.5 mL、pH=7.5、温度35℃、时间9 min能使杨梅红色完全褪色。结果表明,用双氧水作杨梅红色素的褪色剂是可行的。In this article we studied on the effect of hydrogen peroxide on Red Pigment of Myrica Rubra fading by Ultraviolet Spectrophotometry. Factors, such as dosage of hydrogen peroxide, aqueous solution PH value, temperature and time are explored. In the amount of 1mol/L H2O2 7.5 mL, pH=7.5,9 min, 35 time can make Red Pigment of Myrica Rubra completely faded. The results show that using hydrogen peroxide as a fading agent of Red Pigment ofMyrica Rubra is feasible.
