松针茶风味特征的研究
Study on the characteristic flavor of pine needle tea
-
摘要: 目的:分析自制松针茶粉中的风味特征成分。方法:采用气相色谱质谱联用仪(GC-MS),结合Kovats保留指数分别对松针精油和松针茶的挥发性成分进行鉴定,并对两者之间的成分差异进行分析。结果:松针茶粉中检出138个组分,质谱结合保留指数鉴定出19个主要成分,含量较高的组分为α-松油烯(26.7%)。而新鲜松针检出93个组分,质谱结合保留指数定性鉴定出7个主要挥发性成分,含量较高的组分为α-蒎烯(18.9%)、β-蒎烯(22.6%)、水芹烯(29.7%)。结论:实验通过对比,结果显示松针茶中的风味特征物质与松针精油差异较大。Abstract: Objective: To analyze the characteristic flavor in pine needle tea.Methods: The characteristic flavor of the fresh pine needles and pine needle tea were analyzed and identified by gas chromatography-mass spectroscopy ( GC-MS) combined with Kovats retention indices ( KI) .Results: Total 138 components in the pine needle tea were detected by GC-MS and 19 main volatile compounds were identified by MS combined with KI.The highest content of all identified compounds was α-terpinene ( 26.7%) .Total 93 components in the fresh pine needle were detected by GC-MS and 7 main volatile compounds were identified by MS combined with KI.The major components in the volatile oil were α-pinene ( 18.9%) ; β-pinene ( 22.6%) ; α-Phellandrene ( 29.7%) .Conclusion: Comparing the result of the test, the characteristic flavor in the pine needle tea and pine essential oils are quite different.
