Antioxidants, preservation and acidity: a name is not a toxicity verdict
Prepared by TengRip · Sources checked: 2026-10-14
Use ethoxyquin, BHA, BHT, TBHQ, sorbic acid and citric acid as a checking list: purpose, conditions of use and applicable rules come first.
Other common names: 抗氧化、防腐與酸度調整：名稱不是毒性結論, ethoxyquin, BHA, BHT, TBHQ, sorbic acid, citric acid
Names and function
Antioxidation, preservation and acidity control describe different functions. A synthetic name alone does not establish toxicity. FDA evaluates animal-food additives for intended uses and conditions, not every possible exposure.
What the label can and cannot show
FDA has specific animal-feed labeling and use information for ethoxyquin. It documents a U.S. context, not rules for Taiwan, Europe or every cat-food product. Human food and high-dose studies must be distinguished from feline formulations.
A practical checking process
Record the exact product, market, label and manufacturer. Ask about purpose and applicable requirements, and which additives a no-additives claim actually covers. Natural-sounding wording does not prove individual suitability.
Individual and evidence limits
Keep the package and lot. If signs follow feeding, take a full diet and time log to your vet rather than assigning blame to one additive. A label does not establish causation.
