Diallyl disulfide (DADS) is an organosulfur compound with a characteristic garlic-like odor, primarily found in garlic (Allium sativum). It is formed during the processing of garlic and is responsible for many of garlic's health benefits and culinary properties. DADS exhibits antimicrobial, antioxidant, and anti-inflammatory activities, making it significant in both food preservation and health applications. Its sensory characteristics contribute to the flavor profile of various dishes, particularly in Asian and Mediterranean cuisines. DADS is also studied for its potential anticancer properties and cardiovascular benefits.
