基于响应面法的杉木精油提取工艺优化
Optimization of extraction process of essential oil from Chinese fir based on response surface methodology
摘要
Abstract
This study aims to improve the extraction rate of essential oil from Chinese fir and promote the development and utilization of the essential oil.Chinese fir plants of 41 years old from a forest in Nanping,Fujian were used for the extraction of essential oil by the steam distillation method.A single-factor test design was adopted to study the effects of five factors including distillation time,liquid-solid ratio,soaking time,zeolite amount,and sieve mesh size on the extraction rate of essential oil from Chinese fir.An orthogonal design and Box-Behnken response surface methodology were used to optimize the extraction process,and the optimal extraction conditions were determined.The results showed that the single-factor test results indicated that the optimal extraction conditions for the essential oil of Chinese fir were as follows:distillation time of 5 h,liquid-solid ratio of 6 mL·g-1,soaking time of 6 h,zeolite amount of 2.0 g,and sieve mesh size of 3 mm.The orthogonal test results showed that the extraction rate of essential oil reached 1.255%under the distillation time of 5 h,liquid-solid ratio of 5 mL·g-1,and sieve mesh size of 3 mm.The extraction conditions optimized by the response surface methodology were distillation time of 5.1 h,liquid-solid ratio of 5.8 mL·g-1,and sieve mesh size of 3 mm,under which the predicted extraction rate was 1.275%,which was close to the measured value of 1.291%.The comprehensive analysis of the results suggested that the factors affecting the extraction rate of essential oil from Chinese fir were in a descending order of sieve mesh size>distillation time>liquid-solid ratio.关键词
