E353 Metatartaric acid

What is E353 or Metatartaric acid?

E353 Metatartaric Acid is a food additive derived from tartaric acid, primarily used as an acidity regulator and stabilizer in beverages, particularly wines. It helps prevent crystallization and controls the tartness of products to maintain a consistent flavor profile.

Why do I have an intolerance?

Intolerance to metatartaric acid may occur due to difficulties in processing tartaric acid, leading to symptoms such as digestive discomfort, bloating, or nausea. Some individuals may also be sensitive to acids used as preservatives or acidity regulators, which can irritate the stomach lining.

What can I do about it?

If you suspect intolerance, it is best to avoid foods and drinks containing E353, especially wines and processed beverages. Checking labels for additives and choosing products with minimal acidity regulators can help prevent symptoms. Maintaining a balanced diet with natural, unprocessed foods can also reduce exposure to tartaric acid.
