摘要
试验旨在探究不同因素对干姜浸提6-姜辣素的影响,确定干姜浸提6-姜辣素的最佳工艺.试验以6-姜辣素含量为指标,采用单因素试验考察粒径、提取温度、提取时间、提取溶剂、乙醇浓度、液料比和提取次数对6-姜辣素含量的影响.在此基础上,运用正交试验设计选取粒径、液料比、提取时间和提取次数为优化的4个因素,分析确定干姜浸提6-姜辣素的最佳条件.结果显示:干姜浸提6-姜辣素最佳工艺条件为粒径300目、液料比8 mL/g、提取时间40 min、提取次数3次,在此条件下测得3份样品6-姜辣素含量为1.18％～1.19％,干物质得率为7.08％～7.15％.研究表明,此浸提工艺稳定、可行,可为干姜提取物的生产提供参考.
Abstract
The experiment aimed to explore the impact of different factors on the extraction of dried ginger 6-gingerol and to determine the optimal extraction process.The experiment uses the content of 6-gingerol as the index,and adopts single-factor experiments to investigate the effects of particle size,extraction temperature,extraction time,extraction solvent,ethanol concentration,liquid-to-solid ratio,and extraction times on the content of 6-gingerol.On this basis,orthogonal experimental design was used to select particle size,liquid-to-solid ratio,extraction time,and extraction times as the four optimized factors,to determine the optimal conditions for the extraction of dried ginger.The results showed that the optimal extraction process for 6-gingerol in dried ginger was achieved with a particle size of 300 mesh,a liquid-to-solid ratio of 8 mL/g,an extraction time of 40 minutes,and three extraction times.Under these conditions,the content of 6-gingerol in three samples was measured to be between 1.18％and 1.19％,and the dry matter yield was between 7.08％and 7.15％.The study indicates that the selected extraction process is stable and feasible,which can provide a reference for the production of dried ginger extracts.
