Additionally, E223 acts as an antioxidant. It prevents the oxidation of certain food components, helping to maintain the color, flavor, and nutritional value of food items. For example, in fruit juices and wines, sodium metabisulfite can help maintain the vibrant colors and fresh flavors that are appealing to consumers.

One of the primary reasons for the widespread use of nitrites in the food industry is their effectiveness as a preservative. By preventing the growth of bacteria, nitrites help extend the shelf life of products and reduce the risk of foodborne illnesses. Moreover, nitrite preservatives also act as antioxidants, which can help prevent rancidity and improve the overall quality of the meat.

The use of anti-caking agents is not only limited to powdered food products like flour, sugar, and salt; they are also commonly found in various processed foods, seasonings, and spice blends. For instance, when you reach for a container of grated cheese, you may notice an anti-caking agent included in the ingredient list. This agent is crucial in preventing the cheese from sticking together, ensuring that it can be easily poured or sprinkled on dishes.
