草莓果与叶中色素的提取方法和性质研究

Study on the Extraction of Pigment from Strawberry and Its Leaves

以草莓果与叶为原料 ,提取红色素与绿色素 ,并对色素理化性质进行了研究 .结果表明 :酸性乙醇溶液提取红色素效果最佳 ;加入Zn2 +或Cu2 +的 75 %乙醇溶液提取绿色素效果最佳 ;红色素水溶性好、绿色素酯溶性好 ;两色素耐光性、耐热性均好 ;柠檬酸、维生素C、蔗糖。

Extracting haematochrome and chlorophyll from strawberry and its leaves and studying their physical and chemical properties results show the method of extracting haematochrome with acidulous grain alcohol is the best;Extracting chlorophyll with seventy five per cent grain alcohol solution of Zn 2+ and Cu 2+ is the best;The concept of chlorophyll Zn was firstly put forward to here.These pigments have good properties on solubility light and heat resisting,citric acid,vitamin C,cane sugar,sodium bicarbonate and food additive have little effect on the pigment.
