Food Grade Superoxide Dismutase (SOD)
Superoxide Dismutase (SOD) is a key antioxidant enzyme that defends cells against oxidative damage. It catalyzes the conversion of superoxide radicals into oxygen and hydrogen
peroxide, helping to protect bio-macromolecules such as lipids, proteins, and DNA from oxidative stress. Our food grade SOD is produced by advanced microbial fermentation and refined by
multi-step purification, making it suitable for use in food, beverage, and cosmetic manufacturing.
The product is supplied with a declared enzyme activity of 10,000 U/g, providing strong and consistent antioxidant performance in a wide range of applications.
Key Benefits
- Powerful antioxidant activity – efficiently scavenges superoxide radicals and helps reduce oxidative stress.
- Antioxidant function – catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide, used as a functional ingredient in food manufacturing and cosmetic formulations.
- Versatile application – used in functional beverages, cosmetic formulations, animal feed, and food manufacturing.
- Food grade quality – produced under strictly controlled conditions and suitable for inclusion in food manufacturing and commercial applications.
- Good stability – stable within typical food processing pH and temperature ranges when properly handled.
Mechanism of Action
SOD is the first-line enzymatic defense system in many living organisms. It catalyzes the dismutation of superoxide anion radicals (O2•−) into molecular oxygen (O2) and hydrogen peroxide (H2O2):
2 O2•− + 2 H+ → O2 + H2O2
By controlling the level of superoxide radicals, SOD helps prevent lipid peroxidation and oxidative chain reactions. It is commonly found in several isoforms, including Cu/Zn-SOD, Mn-SOD and Fe-SOD, each with specific cofactor metal ions. In formulations, SOD is often used in combination with other antioxidants (e.g. vitamin C, vitamin E) to achieve synergistic effects.

Formulation & Processing Guidance
- Add SOD during the cool-down stage of processing whenever possible to minimize heat inactivation.
- Avoid prolonged exposure to temperatures above its recommended working range.
- Maintain the product within a mild pH environment; extreme acidic or alkaline conditions may reduce activity.
- Use in combination with other antioxidants (e.g. vitamin C, polyphenols) for synergistic protection.
- Exact dosage should be determined through pilot trials based on desired SOD activity in the final product and regulatory considerations in the target market.
