Mannitol is a widely used additive in the food and pharmaceutical industry, it is also known by the code E421. Mannitol is a natural substance that is found in many natural foods such as olives, tomatoes, algae and mushrooms. Its chemical structure is similar to glucose, but with fewer calories and is therefore a frequently used sweetener in diabetic products and other low-calorie foods.

Mannitol is used extensively in confectionery as a sweetener and separating agent to prevent food from sticking together, as well as in chewing gum, diet foods, sugar substitutes, chocolate and other products. Its properties are also important for the pharmaceutical industry, where it is used as a filler in tablets and powders, or as a carrier for pharmaceutical substances. With its low glycemic index and low calorie content, it is ideal for diabetics and people trying to control their sugar intake. However, its use is regulated by the European Union as it can cause digestive problems at higher intakes.
