Antioxidant 392, also known by its E-number designation E-392, is rosemary extract, a potent natural antioxidant derived from the Rosmarinus officinalis plant. It is widely employed in the food industry primarily to prevent oxidation, thus extending the shelf life and maintaining the quality of various food products.
Understanding Rosemary Extract (E-392)
Rosemary extract is rich in phenolic compounds, such as carnosic acid and carnosol, which are responsible for its robust antioxidant properties. These compounds effectively scavenge free radicals and inhibit lipid peroxidation, a key process that leads to rancidity, off-flavors, and discoloration in fats and oils.
Key Characteristics of E-392:
- Natural Origin: It is a plant-derived ingredient, appealing to consumers seeking natural food additives.
- Antioxidant Power: Highly effective in neutralizing harmful free radicals that cause food spoilage.
- Versatility: Can be used in a wide range of food applications, though with specific considerations.
Why is E-392 Useful in Food?
The primary role of E-392 in food is preservation. Oxidation can drastically reduce the quality and appeal of food, especially those rich in fats. By preventing this process, rosemary extract helps maintain the freshness, taste, and nutritional value of products.
- Extends Shelf Life: Significantly delays the onset of rancidity in fatty foods.
- Preserves Flavor and Aroma: Protects sensitive flavor compounds from oxidative degradation.
- Maintains Color: Helps prevent discoloration caused by oxidation in certain food matrices.
- Supports Clean Label Trends: As a natural extract, it aligns well with consumer demand for fewer artificial ingredients.
Specific Application Insight:
Rosemary extract demonstrates particularly good performance in animal fats. This makes it a valuable additive for products like processed meats, poultry products, and fat-based snacks where maintaining freshness and preventing rancidity is critical.
Challenges and Considerations
Despite its effectiveness, rosemary extract (E-392) can present certain challenges, notably issues related to smell and taste. At higher concentrations, its inherent aromatic profile can become noticeable, potentially impacting the sensory characteristics of the final food product. Food manufacturers often address this by:
- Using specific purified extracts with lower odor profiles.
- Optimizing concentrations to achieve antioxidant benefits without sensory interference.
- Combining it with other antioxidants or flavor maskers.
- Considering the food matrix and its compatibility with rosemary's natural aroma.

Broader Context of Natural Antioxidants
Natural antioxidants like E-392 are crucial for enhancing food quality and safety without relying solely on synthetic alternatives. They work by various mechanisms to protect food components from deterioration, thereby contributing to food waste reduction and consumer satisfaction. The ongoing research into plant-derived compounds continues to expand the toolkit available to the food industry for natural preservation.
