Carnosic Acid (E392)

Purpose and Function

Carnosic Acid (E392) is primarily used in the food industry as an antioxidant and flavoring agent. It helps prevent oxidative damage in food products, thus extending their shelf life and maintaining quality. Common applications include:

• Fats and Oils: Used to stabilize oils and fats, preventing rancidity and maintaining flavor integrity.
• Processed Foods: Added to various processed food products to protect against oxidative spoilage, which can lead to off-flavors and undesirable changes in color and texture.
• Beverages: Sometimes included in drinks to help maintain freshness and prevent oxidation.
• Confectionery: Enhances flavor and improves stability in candies and other sweets.
• Meat Products: Used in processed meats to improve flavor and preserve quality.

Carnosic Acid (E392) is derived from rosemary and is valued for its potent antioxidant properties, making it a natural alternative to synthetic preservatives.

Potential Risks and Side Effects
