Abstract

Similarly to other industries wineries also increasingly attempt to minimize and utilize waste to protect our environment. The aim of this study was to determine the optimal parameters (temperature, solvent concentration, and time) of extracting total polyphenol content (TPC) from Tokaji Aszú marc using two different extraction solvents: ethanol–water and isopropanol–water (1:4 solid/liquid ratio). The extractions were achieved based on Central Composite Design with Response Surface Method (CCRD–RSM). The optimal extraction parameters in the case of ethanol–water solvent: 60 °C temperature, 59.5% ethanol concentration in solvent, 5 h. At these parameters the probable TPC concentration is 23966.2 uM GAE/L. The optimal extraction parameters in the case of isopropanol–water solvent: 60 °C temperature, 52% ethanol concentration in solvent, 5 h. At these parameters the probable TPC concentration is 7188.44 uM GAE/L. In both cases the binary solvent was better than the mono-solvent. Ethanol–water solvent was more efficient than the isopropanol–water solvent.

响应面法优化Tokaji Aszú marc中酚类化合物的提取工艺

与其他行业类似，酿酒厂也越来越多地尝试减少和利用废物来保护我们的环境。以乙醇-水和异丙醇-水(料液比1:4)为提取溶剂，确定提取托卡伊Aszú中总多酚含量(TPC)的最佳工艺条件(温度、溶剂浓度和时间)。基于响应面法(CCRD-RSM)的中心复合设计实现提取。以乙醇-水为溶剂的最佳提取条件为:温度60℃，溶剂中乙醇浓度为59.5%，提取时间为5 h。在此条件下，TPC的可能浓度为23966.2 uM GAE/L。以异丙醇-水为溶剂的最佳提取条件为:60℃温度，52%乙醇浓度，5 h。在此条件下，TPC的可能浓度为7188.44 uM GAE/L。在这两种情况下，二元溶剂均优于单溶剂。乙醇-水溶剂的效率高于异丙醇-水溶剂。
