以红薯加工过程中产生的废弃物红薯皮为原料，提取分离红薯皮红色素，不但能够增加红薯深加工产品的附加值，而且能够解决红薯皮作为废弃物造成的环境污染问题，并且可以为食品行业提供一种新的具有保健功能和一定营养价值的天然色素。采用常规的提取方法，在酸性条件下提取制得红薯皮红色素。对制得的红薯皮红色素进行了稳定性研究，考察了温度、pH以及加入相关的金属离子、氧化剂、还原剂、盐、葡萄糖、淀粉、苹果酸等因素的影响，结果表明，制得的色素溶液，在（18~100）℃和pH为2.0~4.0时稳定性良好；氧化剂种类不同，影响效果也不同；盐和Mg2+， Al3+， Na+， Ca2+， Fe3+五种金属离子以及淀粉可使色素色度增加，有一定的增色作用。

Functional and natural pigment was prepared using the conventional extraction method from waste sweet potato peals which produced in the sweet potato processing under acidic conditions , in which the added value of sweet potato was increased and environmental pollution could be reduced. The stability of the sweet potato skin pigment was studied through the effects of temperature , pH value and the influence of added metal ions, oxidant, reducing agent, salt, starch, glucose, malic acid and other factors. The result showed that the pigment was stable at room temperature~100℃and 2.0~4.0 pH value, different kinds of oxidant can affect the stability, moreover, salt Mg2+, Al3+, Na+, Ca2+, Fe3+and starch can increase the pigment's color in a way.
