摘要

芳香槟榔儿茶是西苏门答腊岛的主要农产品之一。它含有单宁,单宁是一种有价值的化合物,广泛用于纺织工业、皮革制品制造或家具工业。从槟榔中提取单宁有望提高其经济价值。本研究旨在通过动态浸渍法提取单宁,浸渍时间分别为1、2、3、4、5小时;乙醇的溶剂浓度分别为35%,50%,65%,80%,96%。所制备的槟榔果粉网目尺寸为e”20,搅拌速度为450转/分,温度为45℃。提取结果浓缩后,用单宁酸标准溶液紫外-可见分光光度法测定。最佳产率为3.750%,浸出时间为2小时,溶剂浓度为65%乙醇。

Variation of Time and Ethanol Solvent Concentration Of Kinetic Maceration Tannin Extraction From Aromatic Areca Catechu
Aromatic areca catechu is one of the main agro commodities in West Sumatra. It contains tannin which are valuable compounds that are widely used in the textile industries, leather product manufacturing, or furniture industries. Utilization of tannin extraction from the aromatic betel nut is expected to increase its economic value. This study aims to extract tannin through kinetic maceration methods by varying the maceration duration of 1,2,3,4, and 5 hours; and varying the solvent concentration of ethanol 35%, 50%, 65%, 80%, and 96%. The scented areca nut powder used has a mesh size of e” 20, the stirring speed 450 rpm and the temperature kept constant at 45 oC. The extraction results were then concentrated and tested by UV-Vis spectrophotometric analysis with a standard solution of tannic acid. Optimal yield value is 3.750%  identified at maceration length of 2 hours with a solvent concentration of 65% ethanol.
