What gives allium vegetables their distinct taste and aroma?
Allium vegetables, such as garlic, onions, leeks, and shallots, owe their distinct taste and aroma to the presence of a specific compound called alliin. Alliin is a flavor precursor that is stored in the cells of the plant and is converted into allicin, a potent sulfur-containing compound, when the vegetable is bruised, chopped, or crushed. Allicin is responsible for the characteristic pungency, flavor, and aroma of allium vegetables. When allicin is released, it reacts with oxygen to form sulfenic acid, which is further broken down into syn-propanethial-S-oxide, a volatile compound that is responsible for the tear-inducing properties of onions and garlic. The combination of allicin, sulfenic acid, and syn-propanethial-S-oxide is what creates the complex and intense flavor profile of allium vegetables, making them a staple ingredient in many cuisines around the world.
