对从紫薯中提取色素的工艺条件进行研究,并对提取的紫薯色素的稳定性进行了研究.以新鲜的紫薯为原料,采用溶剂萃取法提取紫薯色素,考察了不同提取剂对紫薯色素提取效果的影响,并通过单因素实验确定了紫薯色素的最佳提取条件为:以2%碳酸钠溶液作为提取剂,水和紫薯的质量比为1∶1,提取温度为常温,提取时间为10 min.考察了酸度、光、氧化剂对紫薯色素稳定性的影响,经研究发现紫薯色素在酸性、非光照、无氧化剂条件下较稳定.
對從紫藷中提取色素的工藝條件進行研究,併對提取的紫藷色素的穩定性進行瞭研究.以新鮮的紫藷為原料,採用溶劑萃取法提取紫藷色素,攷察瞭不同提取劑對紫藷色素提取效果的影響,併通過單因素實驗確定瞭紫藷色素的最佳提取條件為:以2%碳痠鈉溶液作為提取劑,水和紫藷的質量比為1∶1,提取溫度為常溫,提取時間為10 min.攷察瞭痠度、光、氧化劑對紫藷色素穩定性的影響,經研究髮現紫藷色素在痠性、非光照、無氧化劑條件下較穩定.

The process conditions of extracting pigment from purple sweet potato and the stability of the extracted purple sweet potato pigment are studied in this paper. Taking the fresh purple sweet potato as raw material and using solvent extraction to extract the purple sweet potato pigment, the paper analyzes the effects of different extraction solvents on the extraction of the purple sweet potato pigment. The results of the study show that the optimum extraction conditions are determined by the following factors: with 2% sodium carbonate solution as extraction agent, water and the purple potato mass ratio was 1:1, extraction temperature was room temperature, and extraction time was 10 minutes. The effects of acidity, light and oxidants on purple sweet potato pigment stability are studied to show that the purple sweet potato pigment is more stable under acidic, non-lighting, non-oxidant conditions.
