摘要
以石榴皮为原料,利用水作溶剂提取石榴色素,通过正交实验,研究了提取温度、提取时间和提取的pH值等因素对石榴色素提取率的影响,结果表明石榴皮在60℃和pH为8~9条件下浸提30min,石榴色素提取率较好,且符合当前社会＂绿色环保＂、＂节能减排＂和＂清洁生产＂的要求.
Pomegranate pigment were extracted by using pomegranate peel as raw materials and water as solvent,the effects of the temperature,time and pH values were discussed by means of orthogonal experiments.The results show that under the conditions of 60℃,30min and pH 8~9,the extraction rate of pomegranate pigments is better,and the extraction technology accord with＂green environment protection＂,＂energy saving and pollutant reductions＂ and ＂cleanly production＂.
