The safety of food additives, including E339, is a significant concern for consumers, regulators, and manufacturers alike. Sodium phosphates are generally recognized as safe (GRAS) by food safety authorities, including the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, like all additives, their consumption should be within recommended limits.

Another remarkable category of healthy preservatives includes antioxidants, such as vitamin C (ascorbic acid) and vitamin E (tocopherols). These natural compounds help prevent oxidative stress in food, which can lead to rancidity and spoilage. By incorporating antioxidants, food manufacturers can extend the shelf life of products while also offering added health benefits to consumers. For instance, the inclusion of vitamin C in beverages and snacks not only preserves freshness but can also boost consumers' immunity.
