Allyl propyl disulfide is an organosulfur compound with the chemical formula C₃H₅S₂C₃H₇. It is a volatile pale-yellow liquid with a strong odor. It is a major component of onion oil and is used in food additives and flavors.^[2]

Allyl propyl disulfide is present in garlic and onion. When onion or garlic is sliced, the substance evaporates and causes eyes to irritate.^[3] When garlic or onion is cooked, it also evaporates, ridding them of the spicy taste, and leaving a sweet taste.^{[
