摘要
以新鲜苦瓜为原料,用复合溶剂提取苦瓜中叶绿素,并利用正交试验得出最佳提取条件为料液比1∶4.0,浸提时间3.0 h,浸提温度30℃,乙醇用量12.8 m L,石油醚用量30 m L时,苦瓜叶绿素提取率最高。经检测证明,在此条件下提取率最高可达0.021 5 mg/g。
The fresh Momordica charantia as raw material,extraction of balsam pear pigment by composite solvent,and play the best extraction conditions by orthogonal experiment,the experimental results show that,the optimum extraction conditions for liquid material ratio 1 ∶4.0, extraction time is 3.0 h, extraction temperature of 30 ℃, ethanol dosage is 12.8 m L,petroleum ether as extraction rate of chlorophyll a maximum of 30 m L. The test proves that under this condition the extraction rate of up to 0.021 5 mg/g.
