【摘要】 探讨了天然红心鸭蛋中色素物质的提取及抗氧化活性。结果表明:天然红心鸭蛋中的红色物质呈现类胡萝卜素的特征反应,故其色素中主要成分为类胡萝卜素类物质。以冻干红心蛋粉为原料提取红心蛋黄中的色素物质的最优提取条件为:以石油醚∶丙酮=2∶1为溶剂,温度4O℃,3次提取,每次提取时间60min,料液比为1∶4。更多还原

【Abstract】 The paper discussed the property and distilling condition of the pigment substances in the natural red yolk of duck eggs.The results indicated the pigments in the natural red yolk of duck eggs were carotenoids mostly. The best efective distilling solvent of the freeze-dried red yolk power was:petroleum etheracetone=2l.The best distilling conditionof the freeze-dried red yolk powder was:40°C,60min per time,red yolk powdersolvent=14,distilling 3 times.更多还原
