摘要
在超声波辅助作用下,通过单因素和L9(34)正交试验优化紫甘蓝色素提取工艺,并对提取的紫甘蓝色素稳定性进行研究。结果表明,最佳提取条件:提取剂为蒸馏水、温度60℃、时间50 min、pH值为3、料液比1:35。Fe3+、Sn2+、苯甲酸钠、光照对色素稳定性具有一定的影响。
With ultrasound-assisted extraction technology, by single-factor and L9（34） orthogonal test, extraction conditions of pigment from purple cabbage were optimized, and the effects on the stability of pigment from purple cabbage were investigated. The results showed that the optimum technological conditions of the extraction of pigment from purple cabbage were distilled water for extraction agents, 60℃ for extraction temperature, 50 min for extraction time, pH value for 3, 1：35 for the ratio of the solid and liquid. Metal ions including Fe3＋ and Sn2＋, sodium benzoate, light could have effects on the stability of pigment.
