Abstract

Stevia (Stevia rebaudiana Bertoni) is one of the natural sweeteners which contains low calorie and can be used as a substitute for sugar. The purpose of this study was to determine the effects of solvent ratio and extraction time to the physicochemical characteristics of stevia leaf liquid extract using microwave assisted extraction methods. The observed characteristics were yield of extraction, total soluble solids content, specific gravity and color. The method used in this research was a laboratory experiment with descriptive analysis using 3 different extraction time, which is 4, 5 and 6 minutes. The solvent ratio used in this study were 3 levels, which is 1:30; 1:35 and 1:40 (w/v). The result of this study indicated that extraction variations with material:solvent ratio of 1:30 (w/v) and extraction time of 6 minutes produced the best total soluble solid contents with a value of 2oBrix, meanwhile extraction variations with material:solvent ratio of 1:40 (w/v) and extraction time of 4 minutes produced the best yield of extraction with a value of 87.95%.

微波辅助提取甜菊叶萃取液中溶剂比和提取时间对其理化特性的影响

甜菊糖(Stevia rebaudiana Bertoni)是一种低热量的天然甜味剂，可以作为糖的替代品。采用微波辅助提取的方法，研究了溶剂比和提取时间对甜菊叶萃取液理化特性的影响。考察了其提取率、总可溶性固形物含量、比重和颜色。本研究采用的方法是描述性分析的实验室实验，使用3种不同的提取时间，分别为4,5和6分钟。本研究采用的溶剂比为3级，即1:30;1:35和1:40 (w/v)。结果表明:料液比为1:30 (w/v)、提取时间为6 min时，总可溶性固形物含量最高，为2oBrix;料液比为1:40 (w/v)、提取时间为4 min时，总可溶性固形物提取率最高，为87.95%。
