菊芋叶叶绿素的提取及稳定性研究

Study on Chlorophyll Extraction and Stability from Jerusalem artichoke Leaf

从菊芋叶中提取的天然叶绿素是一种安全无毒的食用色素。本文对菊芋叶叶绿素的提取条件进行了系统的研究，采用L9（3^4）正交试验法确定了最佳提取条件。同时还研究了光照、pH值、氧化剂、还原剂、常用食品添加剂、各种金属离子等对菊芋叶叶绿素稳定性的影响，为菊芋叶叶绿素的开发、利用提供了理论依据。

The natural chlorophyll extracted from Jerusalem artichoke leaf is a kind of safe and non-toxic edible pigment. The systematical studies have been performed on the extracting conditions of the chlorophyll from Jerusalem artichoke leaf. The optimum extraction conditions were obtained by L9 （3^4） experiment. This test also studied the effects of light, pH value, oxidants, reductants, several kinds of food additives, metal ions on the stability of the chlorophyll extracted from Jerusalem artichoke leaf. These researches provided academic basis for the use and exploitation of the chlorophyll extracted from Jerusalem artichoke leaf.
