摘  要:
采用微波蒸馏法提取孜然精油,考察微波溶剂提取和无溶剂提取孜然精油工艺中微波提取时间、微波功率、粒度和液料比等因素对孜然精油提取率的影响。同时以枯茗醛含量作为精油品质的评价指标,并通过GC对孜然精油进行分析。研究结果表明,微波溶剂提取孜然精油的最佳工艺条件为:液料比6:1、微波提取时间90min、微波功率300W,此条件下精油提取率为3.501%,精油中枯茗醛含量为19.121%。微波无溶剂提取孜然精油的最佳工艺条件为:浸泡时间30min、微波提取时间45min、微波功率200W,此条件下精油提取率为2.461%,精油中枯茗醛含量为23.910%。

摘  要:
The microwave-assisted hydrodistillation(MAHD) and solvent-free microwave extraction(SFME) processes of essential oil from cumin seed were optimized through orthogonal test respectively,and the quality of essential oil was analyzed by GC with the content of cuminaldehyde as the evaluation index.Results showed that the optimum conditions of MAHD extraction are as follows:extraction time 90 min,microwave power 300 W,ratio of solvent to raw material 6:1,and under these conditions the extraction yield and the content of cuminaldehyde are 3.501% and 19.121%,respectively.The optimum conditions of SFME extraction are as follows:extraction time 45 min,soaking time 30 min,microwave power 200 W,and under these conditions the extraction yield and the content of cuminaldehyde are 2.461% and 23.910%,respectively.
