Abstract:Objective: To study the main volatile aroma components in chicory extracts. Methods: The volatile components in chicory extracts were analyzed by headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC/MS), the content of volatile components was analyzed by semi quantitative method, and the main volatile aroma components were analyzed by volatile component content/sensory threshold value (odor activity value, OAV). Results: A total of 78 volatile components were detected in the sample. The sequence of volatile components with relative content>1% was propylene glycol>5-hydroxymethylfurfural>acetic acid>1,2-propanediol dicarboxylate>formic acid>1,2-propanediol 2-acetate; The aroma activity values of 24 aroma components were analyzed. The main volatile aroma components with OAV greater than 1 were acetic acid>methyl isobutyrate>ethyl cinnamate>formic acid>methyl cyclopentaenol ketone>2,4-di-tert-butylphenol>5-methylfurfural>propylene glycol. Conclusion: The main volatile components in chicory extract were propylene glycol, 5-hydroxymethylfurfural, acetic acid, 1,2-propanediol dicarboxylate, formic acid, 1,2-propanediol 2-acetate, and the main volatile aroma components are acetic acid, methyl isobutyrate, ethyl cinnamate, formic acid, methyl cyclopentanol ketone, 2,4-di-tert-butylphenol, 5-methylfurfural, propylene glycol.
