中山市家口红心鸡蛋色素物质的提取研究

Study on the Extraction of Carotenoids from Natural Chicken Eggs Red Yolk from Jiakou of Zhongshan City

探讨了中山市三乡镇特产家口红心鸡蛋中色素物质的提取。结果表明，三乡特产家口红心鸡蛋色素物质呈现类胡萝卜素的特征色谱，故其色素中主要成分为类胡萝卜素物质。利用正交试验结合分析与成本，以冻干天然红心鸡蛋蛋黄为原料的提取最优条件为：以石油醚：丙酮=1：2为提取溶剂，温度室温，每次提取时间60min，提取3次，料液比为1：6，可以获得最佳提取效果。

The paper probed into the extraction methods and affective factors on the stability of carotenoids pigments from the natural red yolk of chicken eggs from Sanxiang of Zhongshan city. The results showed： for extracting the carotenoids pigments of freeze-dried red yolk powder the optimum conditions were performed by petroleum ether-acetone = 2：1 （V/ V）, red yolk powder： solvent = 1 ： 6 （ W/V）, extracting 3 times with 60 rain per time and room temperature.
