摘　　要：选取红甘蓝色素提取时间、提取温度和料液比3个因素进行中心组合设计,利用响应面法对其提取工艺参数进行优化研究。利用Design Expert软件对红甘蓝色素提取产量的二次多项数学模型解逆矩阵分析表明:在提取温度为43.6℃,提取时间37.9 m in,料液比1∶21.3时,红甘蓝色素提取产量最高,最大提取产量预测值为8.957 mg.g-1,与实测值相符。利用优化工艺参数提取红甘蓝色素时,具有最大的提取产量。The effects of different temperature, time and the ratio of solid to solution on the extraction yield of red cabbage pigments （RCP） from red cabbage （Brassia oleracea L var. capitata） were investigated based on a three-level three-factor Box-Behnken design. The extraction technique parameters were optimized with Response Surface Methodology. Experimental data were analyzed by solving the regression equation with Design Expert software. It was indicated that the optimum extraction parameters were temperature 43.6 ℃, time 37. 9 minutes and the ratio of solid to solution 1 ： 21.3. Under those conditions, the predicted value of pigments extraction yield from red cabbage was 8. 957 mg·g^-1, which was in consistent with the measured value. It had maximal extraction yield of RCP with optimized technique parameters.
