Looking for a food grade ester stabilizer

[Tōtōchtin]

Know of any? I have read about them in the medical and plastic industry, but I found nothing for the food industry. I'm bad at putting the best form of a question to Google. There must be some additive they put in food to stop the reverse. I've seen hints of zinc and sulfuric acid mentioned in other fields.looking for someone who has stumbled further down the alleys of Rum then myself or a chemist.
