Analysis of Volatile Components of'Qingpi'Fig with Different Maturity Based on HS-SPME-GC-MS
In order to explore the volatile components of Weihai'Qingpi'fig at different maturity stages,the volatile components of fresh fig were analyzed by solid phase microextraction(SPME)and gas chromatography-mass spectrometry(GC-MS),and the flavor components were quantitatively analyzed by internal standard method.The results showed that a total of 73 volatile components were detected,mainly esters,aldehydes,alcohols,olefins,alkanes,etc.Among them,33 species were detected in six mature figs,29 species were detected in eight mature figs,and 36 species were detected in ten mature figs.The volatile components,types and contents of characteristic flavor substances of fig with different maturity were significantly different with the increase of maturity.
