【摘要】 通过单因素试验确定浸提温度、时间和料液比的适用范围,再利用正交试验法进行工艺优化,得出水浸提提取胭脂虫红色素的最佳工艺条件。结果表明,水浸提法提取胭脂虫红色素的最佳提取工艺条件为提取温度为80℃,提取时间为5h,料液比为1:4(m/V);合适的提取级数为6级,红色素提取率为41.89%,其纯度达32.15%。更多还原

【Abstract】 The effects of extraction temperature,extraction time and ratio of raw material to liquid on the extraction of cochineal dye were investigated by single-factor method.Subsequently,these factors were optimized by orthogonal array design.The optimal conditions for the maximum extraction of cochineal dye were determined as follows:with the ratio of raw material to liquid of 1:4(m/V),extraction temperature 80 ℃ for an extraction duration of 5 h,and extraction number 6.Under these conditions,the yield of red dye was 41.89%,and its purity was 32.15%.更多还原
