Preservatives

Preservatives are substances added to food to prevent or inhibit spoilage caused by microorganisms like bacteria, yeasts, and moulds. They can be naturally occurring compounds or synthetically produced. Their primary function is to extend the shelf life of food products by maintaining their quality and safety.

Manufacturers add preservatives to a wide variety of foods to prevent spoilage and maintain freshness. They are commonly found in baked goods, dairy products, processed meats, beverages, and condiments. By inhibiting microbial growth, preservatives help to ensure food remains safe and appealing for longer periods.

Preservatives are authorised food additives in Great Britain and are listed on the Register of Food Additive Authorisations. Their use is regulated to ensure they are safe at intended levels. While generally considered safe at typical intake levels, some individuals may experience sensitivities to certain preservatives. Evidence regarding long-term health effects at typical consumption levels is subject to ongoing scientific review.
