正交组合设计法优化红甘蓝色素提取工艺参数

Optimization of Extraction Technique of Red Cabbage Pigments via Orthogonal Combined Experiment Design

研究了红甘蓝色素提取过程中温度、提取时间对提取产量的影响。在单因素试验的条件下,采用正交试验方法对提取过程的工艺条件进行了优化,确定了红甘蓝色素提取的最佳工艺参数:在料液比为l∶15的条件下,提取时间40 min,提取温度40℃,提取得到的红甘蓝色素产量最高;验证性试验也取得同样的结果。

Effects of temperature and time on extraction yield were investigated in this paper, On the condition of single factor experiment, the extraction technique parameters were optimized with orthogonal experiment design and optimal extracting technique parameters of red cabbage pigments were estimated, which were 40 min, 40 ℃, and meanwhile the ratio of solid to solution was 1：15, Result of proving test had the same technique parameters.
