DuPont Nutrition & Health, New Century, KS, has introduced Guardian Chelox L, a unique, patent-pending blend of natural plant extracts with antioxidant properties that combines strong metal chelation and free-radical scavenging to create a non-allergenic natural solution available for preserving the freshness of food emulsions. Guardian Chelox L gives the makers of mayonnaise, dressings, margarine and spreads a flavor-based, value-adding, natural alternative to EDTA, which has long been the industry’s traditional, synthetic chelator. The higher fat content in many emulsified foods makes them particularly vulnerable to oxidation, which leads to rancidity. Using Electron Spin Resonance (ESR) spectroscopy, DuPont has developed highly sensitive methods for detecting the metal chelating and radical scavenging activity of plant extracts. This technology proved invaluable in identifying the synergistic interaction between plant extracts that makes Guardian Chelox L such an effective inhibitor of lipid oxidation. This synergistic primary/secondary antioxidant activity gives processors a viable alternative to using such traditional, synthetic antioxidants as EDTA, BHA and BHT.
