摘要
目的:探究对比有机溶剂提取法和水蒸气蒸馏法两种提取方法得到的草果精油.方法:以草果为主材料,通过单因素试验优化精油的提取工艺条件.结果:有机溶剂提取法的最佳工艺条件为:液料比1:10、浸提时间2 h、提取温度 40℃,提取率为3.25%;水蒸气蒸馏法的最佳工艺条件为:粒径大小为20目、液料比1:9、浸提时间6 h,提取率为0.8267%.有机溶剂提取法提取率约为水蒸气蒸馏法的4倍,但得到的精油颜色较深、杂质较多;水蒸气蒸馏法提取得到的精油无明显杂质,质量较高,且具有更明显的草果香气.结论:本研究为草果精油的高效提取提供可靠的参数,也为草果精油的进一步开发与应用提供科学依据.
Abstract
[Objective]The two extraction methods of organic solvent extraction and steam distillation were explored and compared.[Method]Using Amomum tsaoko as the main material,the extraction process conditions of essential oil in Amomum tsaoko were optimized through single factor experiments and response surface methodology,and the extraction model with high yield was established.[Result]The optimum technological parameters of organic solvent extraction were solid to solvent ratio of 1:11,extraction time of 2 h,extraction temperature of 40.0℃,extraction rate of 3.25%,while the optimum technological parameters of of steam distillation method were particle size 20 mesh,liquid material ratio 1:9,extraction time 6 h,and extraction rate 0.826 7%.The extraction rate of organic solvent extraction is about 4 times that of steam distillation method,but the essential oil obtained is darker and has more impurities,while the essential oil extracted by steam distillation has no obvious impurities,high quality,and more obvious Amomum tsaoko aroma.[Conclusion]This study can provide reliable parameters for the efficient extraction of essential oil in Amomum tsaoko,and lay scientific foundation for further development and application of essential oil in Amomum tsaoko.
