葵花籽油微乳提取玉米黄粉中天然色素的研究
Study on the Extraction of Natural Pigment from Maize Yellow Powder with Sunflower Oil Microemulsions
摘要
Abstract
The food-grade microemulsions and its application in the extraction of natural edible pigment were investigated in this study.Based on the single factor experiment,solid/liquid ratio,temperature and extraction time were chosen as the factors to optimize technological conditions by design three-level response surface experiment.The optimum process conditions for extracting natural edible pigment from sunflower oil microemulsion were determined,and then the properties of the sunflower oil microemulsion were characterized after extracting.The results showed that the order of factors influencing the extraction rate of pigment was solid/liquid ratio ＞ temperature ＞ time.Using the response surface and SAS software to analyze the data,and the optimal extraction conditions were as follows:the ratio of solid to liquid 1∶42,temperature 71 ℃,and time 1.5 h.The actual value of extraction rate of pigment was 0.34 mg/g under the optimal extraction conditions,which had no significant difference with the theoretical value.The sunflower oil microemulsion had good performance after extracting,and its particle size had no significant change and remained good stability.关键词
