摘要
采用正交试验对石榴籽多酚的提取工艺进行研究。结果表明:温度和料液比对石榴籽多酚提取率的影响较为显著。石榴籽多酚的最佳提取条件为:提取溶剂50%乙醇、浸提温度50℃、提取时间2.0h、料液比1:20,在该条件下石榴籽多酚提取量可达12.07mg/g。
Abstract- Based on single factor test, orthogonal test design was applied to optimize the extraction technology of polyphenols from crushed pomegranate seed （20 mesh）. Results showed that temperature and ratio of solid to liquid had significant effects on extraction yield of polyphenols. Under optimized conditions [with 50% ethanol as extraction solvent, at the ratio of material to the solvent of 1：20 （g/ml）, extracting for 2.0 h at 50 ℃ ], the extraction yield of polyphenols reached 12.07 mg/g.
