摘要
通过单因素实验法优化了南瓜黄色素的提取工艺条件,并对其及稳定性进行了评价,确定了南瓜黄色素提取的最佳工艺条件为:在搅拌条件下,以95%乙醇为提取剂,1∶15的料液比,温度为60℃,提取时间为3 h。色素稳定性试验表明:在常温下南瓜黄色素具有一定抗氧化性和抗还原性,对金属离子稳定,随时间分解缓慢,但高温和光照对色素有破坏作用。
Extracting process for yellow pigment from pumpkin was studied according to the single factor experiment.The optimized conditions were as follows： stirring,95% ethanol as extracting agent,the ratio of pumpkin to extracting agent was 1∶15,the temperature was 60 ℃,extracting 3 h. The experiment about stability of pumpkin yellow pigment showed that at room temperature,yellow pigment had certain inoxidability,reduction- resistant,stability to metallic ion,and decompose slowly. However,yellow pigment from pumpkin would be decomposed speed up at high temperature and illumination.
