摘要
以长白山野生刺五加浆果为原料提取红色素,在单因素试验基础上,通过响应面法优化提取工艺。结果表明,最佳提取工艺条件为乙醇体积分数36.83%、液料比23.78:1(mL/g)、提取时间2.05h,此条件下刺五加浆果红色素吸光度的预测值为0.756,验证实验吸光度为0.751。
Based on one-factor-at-a-time experiments,response surface methodology was used to optimize the extraction of red pigments from the fresh fruits of Acanthopanax senticosus Harms wildly grown in Changbai Mountain.The optimal extraction conditions were found as follows： 36.83% ethanol as extraction solvent,23.78：1 material-to-liquid ratio,and 2.05 h extraction time.Under these conditions,the predicted and experimental absorbance values at 525 nm of extracts was 0.756 and 0.751,respectively.
