摘要： 以色素吸光度的变化定量方法对以甘蔗汁酒精废液为原料提取得到的色素的稳定性进行了研究。结果表明，甘蔗汁酒精废液色素对Ca²⁺、Al³⁺、Mg²⁺、热、蔗糖、山梨酸钾以及柠檬酸具有良好的稳定性；而Fe³⁺、Fe²⁺、Cu²⁺、Zn²⁺、高pH值以及还原剂亚硝酸钠对色素具有不同程度的增色效果，其吸光度分别增加了72.72%、99.00%、21.73%、19.11%、13.31%、19.49%；氧化剂双氧水、还原剂维生素C、紫外光均可使色素产生不同程度的褪色，其吸光度较原来分别下降了87.56%、90.06%、30.54%。

Abstract: Stability of the pigment extracted from the wastewater in sugarcane juice alcohol production has been studied using the change in absorbance. The results showed that Ca²⁺，Al³⁺，Mg²⁺，heat，sucrose，potassium sorbate and citric acid have no obvious influence on the stability of the pigment. Fe³⁺，Fe²⁺，Cu²⁺，Zn²⁺，higher pH value and NaNO₂ can enrich the color of the pigment and the absorbance is increased by 72.72%，99.00%，21.73%，19.11%，13.31% and 19.49% respectively. However，H₂O₂，ascorbic acid and ultraviolet light have significant influence on the stability of the pigment and make the color of the pigment degrade seriously，the absorbance is decreased by 87.56%，90.06% and 30.54% respectively as compared with the original pigment.
