Description and Uses

Carnosic Acid is a phenolic component of rosemary. It acts as a potent antioxdant and also has UV protective activity. Specifically protection for UV-A radiation and damage. Carnosic Acid also inhibits the free-radical chain reaction that leads to the oxidation of fats and oils, thereby stabilizing and increasing the shelf life of meats.
