Analysis and Simulation of Volatile Aroma Constituents of Jiayongxin Preserved Beef by ASE-SAFE and SDE-GC-MS

The volatile aroma constituents of Jiayongxin preserved beef were extracted by accelerated solvent extraction-solvent assisted flavor evaporation(ASE-SAFE) and simultaneous distillation extraction(SDE),and identified by the gas chromatography-mass spectrometry.The results show that a total of 82 compounds were identified and they were 6 hydrocarbons,20 aldehydes,10 alcohols,11 ketones,4 phenols,16 acids,3 ethers,1 ester and 11 sulfur-containing compounds,nitrogen-containing compounds and heterocyclic compounds,respectively.16 compounds were all identified by two methods,including hexanal,heptanal,benzaldehyde,nonanal,2-furanmethanol,linalol,α-terpineol,(-)-terpinen-4-ol,1-hydroxy-2-propanone,acetoin,2,3-pentanedione,piperitone,eugenol,eucalyptol,anethole and dihydro-2-methyl-3(2H)-furanone.
