摘要
以蘘荷穗状花序苞片为原料提取红色素,比较了微波烫漂辅助法与其它不同方法及不同溶剂对红色素提取得率的影响,利用单因素实验和正交L16(44)实验研究了微波烫漂后蘘荷苞片红色素提取的工艺条件,结果表明经微波烫漂处理后,用酸性乙醇提取蘘荷苞片红色素效果较好;最佳工艺条件为:体积分数60%的酸性乙醇为提取剂,料液比1∶60(g/mL),提取温度55℃,时间40min,此条件下红色素的得率为345.8mg/100g。
The red pigment was extracted from Zingiber mioga Rosc.Microwave blanching and other methods were compared while the effects on extraction of different solvents were also investigated.The optimum extracting conditions of red pigment in Zingiber mioga Rosc were studied by using single factor analysis and orthogonal test L16 （44）.Results showed that the optimum extraction conditions were 60% acidic alcohol to extract 40min at 55%, with the ratio of material to solution 1：60（g/mL） ,and the red pigment was 345.8mg/100g.
