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