Onion Oil

Onion oil is an essential oil extracted from onions, typically using steam distillation. It captures the pungent aroma and flavor of onions in a concentrated liquid form. The process involves heating onions with steam, which vaporizes the volatile compounds, and then cooling the steam to collect the oil.

Manufacturers use onion oil to impart a strong onion flavor and aroma to foods without adding the texture of chopped onions. It is frequently found in savory products like sauces, dressings, soups, snack foods, and processed meats. Its concentrated nature allows for potent flavor delivery with small amounts.

In the US, onion oil is generally recognized as safe (GRAS) by the FDA for use as a flavoring agent. Regulatory bodies like JECFA and EFSA have evaluated similar flavoring substances. At typical consumption levels found in food, onion oil is not associated with adverse health effects. Research into the specific health impacts of concentrated onion oil is ongoing, but it contains compounds also found in onions, which have been studied for various health properties.
