摘要:

为建立高效、便捷的罗汉果多酚的提取工艺,采用闪式法提取罗汉果多酚,并利用响应面分析法确定罗汉果多酚的最佳提取条件为液料比25:1(mL/g)、电压153V、温度8.5℃、时间3.5min,在此条件下罗汉果多酚的提取率达到2.73%。本研究建立了闪式提取法提取罗汉果多酚的数学模型,并得到了最佳的提取条件。

关键词: 罗汉果, 多酚, 闪式提取, 响应面分析法

Abstract:

The flash extraction method was employed to extract polyphenols from the fruits of Siraitia grosvenorii, and the extraction parameters were optimized by means of response surface methodology. The optimum conditions were obtained as follows: biomass-to-solvent ratio 1:25, voltage 153 V, temperature 8.5 ℃, time 3.5 min, and the polyphenols yield 2.73%. The mathematical model of flash extraction of polyphenols from Siraitia grosvenorii was established and the optimal condition was obtained, which offered reference for the industrial extraction of polyphenols of Siraitia grosvenorii.

Key words: Siraitia grosvenorii, polyphenols, flash extraction, response surface methodology
