Diallyl Disulfide (DADS) is a food-grade primary organosulfur compound in garlic oil.We supply bulk Diallyl Disulfide sourced from leading China manufacturers, available in liquid and oil forms for food and beverage manufacturers worldwide. Our Diallyl Disulfide is widely used in garlic flavour formulations, food flavouring, health supplement active ingredient, antimicrobial food preservation and pharmaceutical research.
Diallyl Disulfide (CH₂=CHCH₂SSCH₂CH=CH₂) is the most abundant organosulfur compound in steam-distilled garlic oil (40-50%).
It is formed by allicin decomposition during garlic processing. DADS provides the characteristic pungent, cooked-garlic flavour and is responsible for many of garlic's health-promoting properties including antimicrobial, cardiovascular-protective and anticancer activities.
