Chemical Composition

Garlic contains a wealth of sulfur compounds; most important for the taste is allicin (diallyl disulphide oxide), which is produced enzymatically from alliin (S-2-propenyl-L-cysteine sulfoxide) if cells are damaged; its biological function is to repel herbivorous animals. Allicin is deactivated to diallyl dysulphide; therefore, minced garlic changes its aroma if not used immediately. In the essential oil from steam distillation, diallyl dysulphide (60%) is found besides diallyl trisulphide (20%), diallyl sulfide, ajoene and minor amounts of other di- and polysulphides.
