What is Preservative?

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 found in plants or produced synthetically. Their primary function is to extend the shelf life of food products by maintaining their quality and safety.

Is Preservative a major allergen?

Preservatives themselves are not among the 14 major allergens that UK law requires to be emphasised on food labels.

What is Preservative used for?

Manufacturers add preservatives to a wide range of foods, including processed meats, baked goods, sauces, and beverages, to prevent microbial growth and spoilage.

Is Preservative safe?

Preservatives are subject to strict regulation in the UK and must be authorised and listed on the Register of Food Additive Authorisations before they can be used.

Why it's used

Manufacturers add preservatives to a wide range of foods, including processed meats, baked goods, sauces, and beverages, to prevent microbial growth and spoilage. This helps to maintain the food's flavour, texture, and appearance over time. Common examples include sorbates, benzoates, and nitrites.

Health notes

Preservatives are subject to strict regulation in the UK and must be authorised and listed on the Register of Food Additive Authorisations before they can be used. European bodies like EFSA have evaluated many preservatives for safety. While generally considered safe at typical consumption levels, some individuals may experience sensitivities to certain preservatives. Research into potential long-term effects is ongoing, and regulatory bodies continue to monitor scientific evidence.

Allergen info

Preservatives themselves are not among the 14 major allergens that UK law requires to be emphasised on food labels. However, some preservatives, such as sulphur dioxide and sulphites, must be declared if present above 10 mg/kg or 10 mg/litre, as they can cause reactions in sensitive individuals.
