Research behind the verdict
- Calcium Tartrate Stabilizers in Food: Safety and Efficacy Analysis — Food Stabilization Research Group, Journal of Food Processing and Safety (2024). A comprehensive 2024 study evaluating calcium tartrate (E354) and related stabilizers in food applications. The research examined the compound's role in preventing crystallization and its safety profile as a food additive. Calcium tartrate demonstrated excellent safety characteristics with no adverse effects observed in toxicological studies. The study noted that calcium tartrate occurs naturally in wine-making processes and provides a safe method for tartrate stabilization. No concerns were identified regarding its use as an approved food additive.[safe]
