Carnosic AcidUsage

1. As a fat-soluble natural antioxidant, carnosic acid has far better antioxidant effects than synthetic antioxidants in stabilizing oils and fats.

2. It can be used in oils and fats, bio-pharmaceuticals, chemicals, cosmetics and feeds, in addition to preventing or delaying the oxidation of oils or oily foods, improving the stability of foods and prolonging the storage time of stored foods. Flavoring agents for fish and fish.

3. In Japan, rosemary extract is used in high-temperature fried foods to prevent oxidation and prevent post-package photodegradation, and can also be used in frozen foods to suppress fishy smell.

4. In Europe, rosemary extract is also used to prevent oxidation of ham and sausage products.

5. The application of a dilute seasoning oil type product with rosemary extract is very suitable for meat products.
