Humectant

Humectants are ingredients that help retain moisture in food products. They are typically hygroscopic, meaning they attract and hold water from the surrounding environment. Common sources include glycerol (also known as glycerine), sorbitol, and certain sugars or sugar alcohols.

Manufacturers use humectants to prevent food from drying out, maintaining its texture and extending shelf life. They are often found in baked goods like cakes and pastries, confectionery, and dried fruits. By keeping products moist, humectants ensure a desirable eating experience.

Humectants such as glycerol and sorbitol are authorised food additives in Great Britain, listed on the Register of Food Additive Authorisations. At typical levels of consumption found in food, they are generally considered safe. Some sugar alcohols, if consumed in very large quantities, can have a laxative effect.
