EDTA (ethylenediaminetetraacetic acid) is a powerful chelating compound that forms stable complexes with divalent and trivalent metal ions. In food processing, it is used to prevent metal-catalyzed oxidation, discoloration, and flavor degradation.
EDTA is particularly effective at extending the shelf life of products containing fats and oils susceptible to oxidative rancidity. It works synergistically with other antioxidants and preservatives to provide comprehensive product protection. The compound is available in various salt forms to suit different food processing requirements and pH conditions.
