| 摘 要： | 以食用紫甘蓝菜为原料,用pH值为2的盐酸溶液浸提得到紫甘蓝色素.着重研究了蔗糖、柠檬酸、抗坏血酸、金属离子、氧化剂、还原剂对紫甘蓝色素稳定性的影响.结果表明:紫甘蓝色素水溶性好,在酸溶液中很容易被提取.该色素在酸性条件下对常用的食品添加剂蔗糖、柠檬酸具有较好的稳定性;金属离子Fe3+、Sn2+、氧化剂、还原剂对色素的稳定性影响较大.

| Abstract: | Extract the violet cabbage pigment from the edible violet cabbage by hydrochloric acid of pH = 2.Study on the influence of sucrose,citric acid,ascorbic acid,ion metals,oxidizer,reductant etc.to the stability of violet cabbage pigment.The results show that the violet cabbage pigment has a good water-soluble,it can be easily extracted in acid solution.This pigment has a better stability to food additive such as sucrose,citric acid in common use under acid condition;but has a worse stability under Fe3 ,Sn2 ,oxidizer,reductant condition. |
