Tartaric acid also exhibits antioxidant properties, which can help protect food products from oxidation. By preventing the oxidation of fats, oils, and certain food colorants, tartaric acid helps preserve the freshness and shelf life of products. For example, in fruit juices and fruit-based desserts, tartaric acid can prevent the degradation of vitamin C, ensuring that the product retains its nutritional value and color. As an antioxidant, it also helps maintain the flavor integrity of the product by preventing off-flavors caused by oxidation, ultimately contributing to a better consumer experience.
