Key Oxidative Stability Tests
Peroxide Value (PV)
What It Measures
Residual antioxidants refer to the remaining antioxidant compounds in a material (such as food, polymers, or biological systems) after processing, storage, or exposure to environmental factors. This measurement assesses the stability and effectiveness of antioxidants that prevent oxidative degradation.
Why It Matters:
- Food and Nutrition: Residual antioxidants in food help determine shelf life, nutrient retention, and protection against rancidity in fats and oil.
Oxidative Stability Index (OSI)
What It Measures:
OSI measures the induction period of an oil or fat before rapid oxidation begins under accelerated conditions.
Why It Matters:
- A longer OSI indicates greater resistance to oxidation.
- OSI is a reliable predictor of the shelf life of products stabilized with antioxidants.
Anisidine Value (AV)
What It Measures:
Anisidine Value testing detects secondary oxidation products, such as aldehydes, which contribute to off-flavors and odors in fats and oils.
Why It Matters:
- AV reflects the later stages of oxidation, providing a comprehensive picture of overall oxidative stability.
- Monitoring both PV and AV offers a complete understanding of antioxidant performance throughout the oxidation process.
Shelf-Life Testing
In addition to oxidative stability tests, shelf-life studies are conducted to evaluate the long-term performance of our antioxidants under real-world storage and handling conditions.
What It Involves:
- Products are stored under controlled conditions (ambient, elevated, or accelerated temperatures).
- Regular sampling is performed to assess changes in PV, OSI, and AV, as well as sensory qualities like taste and odor.
Why It Matters:
Shelf-life testing ensures that our antioxidants effectively extend the freshness and nutritional value of your products throughout their intended lifespan.
Residual Testing
What It Measures
Residual antioxidants refer to the remaining antioxidant compounds in a material (such as food, polymers, or biological systems) after processing, storage, or exposure to environmental factors. This measurement assesses the stability and effectiveness of antioxidants that prevent oxidative degradation.
Why It Matters:
- Food and Nutrition: Residual antioxidants in food help determine shelf life, nutrient retention, and protection against rancidity in fats and oil.
