Rosemary Extract Antioxidant

The Evolution of Feed Preservation: Why Rosemary?

In the global livestock industry, maintaining the oxidative stability of fats, oils, and fat-soluble vitamins is critical for feed quality and animal performance. Wellgreen’s Rosemary Extract Antioxidant offers a powerful, plant-based alternative to traditional synthetic antioxidants like BHA, BHT, and Ethoxyquin.

Our extraction process focuses on Carnosic Acid, a lipid-soluble phenolic compound that acts as a "sacrificial" antioxidant, neutralizing free radicals before they can damage your feed’s nutritional integrity. By choosing our rosemary oil extract, producers can ensure a longer shelf life and better palatability without the regulatory risks associated with synthetic chemicals.

Strategic Advantages: Powder vs. Oil Formats

We recognize that different production lines require specific physical properties. Wellgreen provides two primary delivery systems:

Rosemary Extract Oil (Liquid): Ideal for direct injection into oil-addition systems or fat-coating processes in pet food and high-energy livestock feed. Our rosemary extract oil offers excellent transparency and rapid dispersion in lipid phases.

Rosemary Extract Powder (Dry): Standardized for dry premixes, mineral blends, and mash feeds. Our powder format is engineered for high flowability and consistent distribution throughout the feed matrix.

FAQ

• Which is better for fish oil, the oil or the powder? For liquid lipids like fish oil, Rosemary extract oil is highly recommended as it integrates instantly at the molecular level, providing more uniform protection.
• Can your Rosemary Extract replace Ethoxyquin completely? Yes. Many of our global partners have successfully transitioned to a Rosemary-based system, often achieving superior stability when combined with mixed tocopherols.
• Does it have a strong rosemary scent that might affect feed intake? We use advanced de-odorization technology for our feed-grade products, ensuring a very mild aroma that does not affect animal palatability.
• What is the recommended inclusion rate? Typically 100g to 1000g per ton of complete feed, depending on the fat content and the desired shelf-life target.
• Is it heat-stable for extruded pet food? Absolutely. Our Carnosic acid-rich extracts are specifically chosen for their high-temperature stability compared to other botanical antioxidants.
