Rosemary Extract
Rosemary extract is a concentrated antioxidant fraction from Rosmarinus officinalis leaves, rich in phenolic diterpenes such as carnosic acid and carnosol, often with rosmarinic acid depending on process. Food technologists use oil-soluble and water-dispersible grades to protect meat, oils, fried snacks, and pet foods from oxidative rancidity under a clean-label botanical story. Deodorised grades strip most herb aroma so the extract can work in neutral fat systems without shouting “rosemary.” Quality material has a declared carnosic acid content, low residual solvent where applicable, and a colour from pale green-gold to brownish depending on concentration. It is not a full antimicrobial preservative package; it targets lipid oxidation. Overdose can still add bitter herbal notes. Store cool and dark in sealed containers. Distinct from culinary rosemary herb: this leaf is the refined antioxidant extract.
Also known as: E392, Rosemary extract, Rosemary extract, Extracto de romero, Extrait de romarin, Mannenrō ekisu

History
Mediterranean cooks preserved meats with rosemary long before phenolic antioxidants were identified.
Laboratory work isolated carnosic acid and related diterpenes as potent lipid antioxidants.
Commercial deodorised rosemary extracts entered meat and oil industries as natural antioxidant alternatives.
E392 authorised rosemary extracts as antioxidants under European additive regulations.
Standardised carnosic-acid grades and water-dispersible forms widened snack, emulsion, and clean-label use.
