E281 is classified as a food preservative under the E number system, which categorizes food additives based on their functional characteristics. Specifically, sodium propionate is utilized primarily in baked goods, dairy products, and processed meats. Its ability to inhibit spoilage organisms, particularly molds, is particularly valuable in enhancing the longevity of bread, cakes, and other perishable items. By using E281, manufacturers can ensure their products remain safe and appealing to consumers for a more extended period.
