The main compounds responsible for that flavour are mostly sulfur-containing, non-volatile amino acids (thiosulfinates), among which alliin or S-allyl-cysteine sulfoxide (ACSO) is the most predominant garlic flavour precursor ( Block et al., 1993, Horníčková et al., 2010; Fig. Antimycobacterial and Antibacterial Activity of Allium sativum Bulbs. Garlic (Allium sativum L.) is an aromatic herbaceous plant that is consumed worldwide as food and traditional remedy for various diseases. The type of molecule that produces an odor is called an aroma compound or an odorant. When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. The major sulfur-containing compounds in intact garlic are γ-glutamyl-S-allyl-L-cysteines and S-allyl-L-cysteine sulfoxides (alliin). doi: 10.1016/j.ttbdis.2019.04.016.
