Research of the volatile composition in garlic sprouts by SPME / GC / MS method

The volatile components of garlic sprouts from four producing area were analyzed by SPME / GC / MS method.The research results showed that 100 μm PDMS extraction column was suitable for analysis of the volatile components in garlic sprouts.The sum of peak area of volatile composition in garlic sprouts from Yongnian,Huimin,Shanghe,Guangrao was separately 98.99%,92.43%,74.22% and 99.8%,among them,the volatile components.in garlic sprouts from Guangrao were the most.The common sulfocompound in garlic sprouts from four area were Diallyl disulphide,Trisulfide methyl 2- propenyl,Trisulfide di-2- propenyl,1- Propene 3,3'- thiobis,Disulfide methyl2- propenyl,3- Vinyl- 1,2- dithiacyclohex- 4- ene,1,3- Dithiole- 2- thione,3,4- Dimethylthiophene,1,3- Dithiane,Diallyl disulphide content were the highest among them.Further analysis showed that the sulfocompounds content from different parts of garlic sprouts had some differences,sulfocompounds content order was root > central stem> upper stem. This research had great significance to promote garlic sprouts processing and broaden garlic sprouts industry chain.
