摘要: 本研究利用β-葡萄糖苷酶水解干桂花以充分释放桂花中的香味前驱体,然后用乙醚为溶剂萃取出水解桂花中的香味产物,得到桂花浸膏产品,从而达到提高桂花浸膏产品得率和产品质量的目的。通过实验,研究了β-葡萄糖苷酶的用量、水解时间、水解温度等因素对提取效果的影响,并最终得到酶水解提取的最佳工艺参数。实验结果表明,与传统提取方法相比,采用酶水解后提取桂花浸膏,产品得率提高了40%以上,浸膏产品中的净油含量提高了11%,达到了预期的实验目的。

Abstract: In this study,β-D-glucosidase was used to hydrolyze Osmanthus fragrans in order to release flavor precursors.After the hydrolysis,the flavor precursors from Osmanthus fragrans were extracted with aether.By this way,the extraction rate and quality of Osmanthus fragrans extract were improved.The extraction conditions such as dosage of b-D-glucosidase,hydrolysis temperature and time were optimized by single factor test and orthogonal test.The experimenal results indicatd that compared with traditional extraction method the the extraction rate of Osmanthus fragrans extract is increased by 40% and the content of absolute oils in Osmanthus fragrans extract is increased by 11%.
