摘  要:
采用溶剂法对酿酒后的葡萄皮渣中酒石酸的提取工艺进行了研究。试验以酒石酸的提取率为考察指标,通过单因素和正交试验对酒石酸提取工艺进行优化。结果表明,最佳提取工艺为:料液比1∶12(g/mL),提取温度85℃,提取时间4.0 h,提取剂pH 4.0,在此条件下,葡萄皮渣中酒石酸平均提取率为1.079%。

摘  要:
The tartaric acid was extracted from the grape pomace after brewing by solvent method. Using the extraction rate of tartaric acid as indicators, the extraction processes were optimized with single-factor and orthogonal test. The results showed that the optimal extraction processes were as follows: solid and liquid ratio 1∶12(g / mL), extraction for 4 hours at 85 ℃ and under pH 4.0. Under thoptimal condition, the average extraction rate of tartaric acid was 1.079%.
