摘要: 采用有机溶剂萃取法对香荚兰浸膏进行精制,通过电子鼻、感官评定确定最佳溶剂,以主要化合物含量为指标优化溶剂比例及萃取次数,利用气相色谱-质谱法检测浸膏精制前后挥发性成分相对含量。结果表明:最佳溶剂为乙酸乙酯-正丁醇、溶剂体积比3∶7、萃取3次时香草醛相对含量最高为9.48%,香荚兰浸膏精制效果较好;浸膏精制后,芳香族类化合物相对含量由35.58%增加至51.00%,烷烃类化合物相对含量由4.42%减少至0.78%。该研究结果可为香荚兰浸膏综合利用及产品研发提供理论参考及技术支持。

Abstract: Vanilla extract was refined by organic solvent extraction. Different solvents were tested for their extractability using electronic nose and sensory evaluation. Solvent composition and number of extraction cycles were optimized for higher retention rates of major components. The volatile components before and after the extraction were compared by gas-chromatography-mass spectrometry (GC-MS). The results showed that the optimized conditions that provide maximum vanillin content (9.48%) were found to be extraction performed 3 times using a mixture (3:7, V/V) of ethyl acetate and n-butanol as extraction solvent. After the extraction, the proportion of aromatic compounds was increased from 35.58% to 51.00%, along with a decrease in the proportion of alkanes from 4.42% to 0.78%. These results can provide a theoretical basis and technical support for the comprehensive utilization of vanilla extract and product development.
