Rosemary Extract To Maintain Freshness

Rosemary extract is a natural antioxidant derived from the leaves of the rosemary plant (Rosmarinus officinalis). It is typically produced by extracting the active antioxidant compounds, such as carnosic acid and rosmarinic acid, using solvents like water, ethanol, or supercritical carbon dioxide.

Manufacturers add rosemary extract to foods to help maintain freshness by preventing fats and oils from becoming rancid. This antioxidant action extends the shelf life of products. It is commonly found in processed meats, baked goods, snacks, and dairy products.

In the United States, rosemary extract is generally recognized as safe (GRAS) by the FDA for use as a flavoring and antioxidant. Regulatory bodies like JECFA and EFSA have evaluated rosemary extract and its components. Research suggests that the antioxidant compounds in rosemary may have beneficial health properties, but more studies are needed to confirm these effects at typical dietary intake levels.
