搅拌吸附萃取结合气相色谱串联质谱法分析传统六堡茶挥发性成分
Analysis of the Volatile Components of Traditional Liupao Tea by using Adsorption Extraction Combined with Gas Chromatography-tandem Mass Spectrometry
摘要
Abstract
To explore the volatile components and key aromatic substances of traditional Liupao tea,the gas chromatography-mass spectrometry technique combined with relative odor activity value and flavor wheel techniques was used to analyze three traditional Liupao tea samples.In total,39 aromatic compounds were identified from six categories of aromatic hydrocarbons,alcohols,ketones,aldehydes,alkenes,and heteroxy compounds.The volatile components and relative contents of samples significantly differed.Nongjia Liupao tea contained high alcohol(62.66%)and oleic(26.64%)volatile compound contents,Liupao tea fruit contained high alcohol(81.10%)and aldehyde(3.62%)volatile compound contents,and Liupao old tea contained high alcohol(56.13%)and oleic(36.95%)volatile compound contents.α-cedarol exhibited the highest relative content of volatile components(38.92%～49.12%)in traditional Liupao tea samples.α-cedarol,vedranol,allocedarol,and β-linalool contents were determined by the ROAV values of the samples as volatile components(ROAV>1.00);citronellal,trans-2-octenal,2-n-amylfuran and other seven compounds had modification effects on the aroma of samples(0<ROAV≤1.00).In addition,the flavor profile and flavor wheel were constructed to determine the main flavor attributes of the samples,including woody,fruity,floral,fungal,and aged aromatic volatile components.This study provides a theoretical basis for the formation and changes of specific flavors in the production and processing of traditional Liupao tea.关键词
