What it is

Food preservatives are substances added to food to prevent spoilage caused by microorganisms like bacteria, yeasts, and molds. They can be naturally occurring or synthetic. Preservatives help extend the shelf life of food products, allowing them to be stored and transported for longer periods.

Why it's used

Manufacturers add preservatives to maintain the quality and safety of food products. They prevent the growth of microbes that can cause food to spoil, change texture, or become unsafe to eat. Common foods that contain preservatives include baked goods, processed meats, dairy products, and snack foods.

Health notes

In the U.S., the FDA regulates food additives, including preservatives, to ensure they are safe for consumption. Many preservatives are Generally Recognized As Safe (GRAS) or approved for specific uses. International bodies like JECFA and EFSA have also evaluated many preservatives. While generally safe at typical intake levels, some individuals may have sensitivities to certain preservatives. Research continues to explore the long-term health effects of various preservatives.

Allergen info

Most common food preservatives are not derived from the major allergens. However, if a preservative is derived from a source like wheat or soy, it would be considered a derivative of a major allergen. Always check the ingredient list for specific sourcing.
