摘要
采用单因素试验和正交试验对内部沸腾法提取葡萄皮花色苷工艺进行研究,探讨乙醇体积分数、提取温度、提取时间和水料比对葡萄皮花色苷提取的影响。确定最佳提取工艺参数为:乙醇体积分数90%、提取温度85℃、提取时间5 min、提取水料比30 m L/g。按此优化条件,提取效果最佳,试验重现性好。
The single factor test and orthogonal test were used to study the extraction process of anthocyanin from grape skin by internal boiling method. The effects of ethanol volume fraction, extraction temperature, ex-traction time and ratio of water to material on the extraction were discussed. Optimum extraction parameters as follows： the ethanol volume fraction was 90 %, the extraction temperature was 85 ℃ , the extraction time was 5 min, and the ratio of water to material was 30 mL/ g. Under these conditions, the extraction efficiency reached the best and the test reproducibility was good.
