提取陕西生姜姜油的工艺条件研究

Study on the extraction process conditions of ginger oil from fresh ginger grown in shaanxi province

以陕西本地种植的生姜为原料,以石油醚为溶剂,采用索氏提取法提取姜油,考察了料剂比、提取温度及时间对姜油产率的影响,通过GC-MS进行成分分析。结果表明,最佳提取时间为3 h,提取温度为90℃,料剂比(生姜∶石油醚)为1∶6(g∶mL)。在此条件下,提取率为10.9%,姜油中主要成分为姜烯、姜黄烯、橙花叔醇。

Wet and fresh ginger grown in Shaanxi was extracted ginger oil by Soxhelt method which used t petroleum ether as solvent. Influence of the material agent ratio, extraction temperature and time on ginger oil yield were investigated. All the ginger oil was analyzed of chemical component by GC-MS. The resuhs showed that the optimum time for extraction was 3 h, the extraction temperature was 90 ℃, and the mate- rials ratio （ ginger ： petroleum ether） was 1 ： 6 （ g ： mL）. The oil extraction rate under the most favorable conditions was 10.9%, the main ingredient is Zingiberene, curcumene and nerolidol.
