Scientific Evidence
Research Findings
You might wonder if these additives really keep food safe. Scientists have tested sodium erythorbate and Isoascorbic Acid for their antioxidant power. Erythorbic acid, also called D-ascorbic acid, is a food additive with strong antioxidant effects. It does not work as well as L-ascorbic acid. It only has about 5% of L-ascorbic acid’s power. Erythorbic acid stays stable when it is dry. But it breaks down fast in water if air gets to it. This means it works best in dry foods or foods packed quickly. Sodium erythorbate helps keep color in meats and baked goods. It does not give you vitamin C, even though it looks like it. It is good for stopping food from turning brown or losing taste. Scientists agree that both additives help slow down spoilage. They help keep food fresh for a longer time.
