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%。
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%.
