Abstract:

A large amount of waste liquid is produced in the processing of garlic slices. The research aims to provide a basis for the comprehensive utilization of this waste liquid which has lots of bioactive components. We analyzed the bioactive components of the processing liquid and the fermentation broth by gas chromatography-mass spectrometer (GC-MS) and liquid chromatography-mass spectrometry (LC-MS). The results show that the processing liquid of garlic slices mainly contains volatile sulfur-containing compounds such as diallyl disulfide (DADS), 2-vinyl-4H-1,3-dithiene (vinyldithiins) and so on. The volatile components in the fermentation broth include methyl-l-arabinopyranoside, butyric acid and pentanoic acid. The processing liquid of garlic slices contains non-volatile components, mainly γ-L-glutamyl-S-(2-propenyl)-L-cysteine, and illisimoid A and 5'-(hydroxysulfonyloxy) jasmonic acid are the main non-volatile components in the fermentation broth. The volatile and non-volatile components in the processing liquid of garlic slices can be used as the source of effective active substances.

Key words: processing of garlic slices, processing liquid, fermentation broth, volatile components, non-volatile components
