Maltodextrin: what is it, where is it used and is it harmful?

01 · What is maltodextrin?

It is a mixture of shorter glucose chains formed by partially breaking down starch. The raw material may be maize, potatoes or other starch-rich plants. Individual products differ depending on how they are manufactured.

Maltodextrin may taste only slightly sweet, but it is a digestible carbohydrate. It should not be considered calorie-free simply because it does not taste like table sugar.

02 · Why is it used in food?

Manufacturers may use it as a carrier for flavourings and other ingredients, or to adjust texture, solubility or the flow of powders. In some products, it performs several technological functions at once.

Its presence alone does not determine the quality of the whole food. The amount, the complete formulation and how often the product is included in the diet all matter.

03 · Where might you find it?

Maltodextrin may be found in instant drinks, sports nutrition products, seasoning blends, powdered foods or as an auxiliary ingredient in some food supplements. Its inclusion in the ingredients list does not reveal its exact amount.

It is usually listed by the name maltodextrin. Ingredients are generally listed in descending order by weight at the time they are used in manufacture. To assess total carbohydrates, also check the nutrition information per 100 g or 100 ml and per serving.

04 · Maltodextrin and blood sugar

Digestible maltodextrin is broken down into glucose in the digestive tract and can therefore raise blood sugar. The specific response depends on the amount, the composition of the meal and the individual's condition.

A review of digestible maltodextrins notes that replacing less processed starch with maltodextrin may increase the glycaemic load of a meal.

05 · Is maltodextrin harmful?

Calling the substance harmful in every use would be inaccurate. At the same time, the amount of rapidly digestible carbohydrates in the diet should not be overlooked. Portion size, the overall food composition and individual needs all matter.

In sports nutrition, for example, a rapid carbohydrate supply may be intentional. In another product, a small amount may act as an ingredient carrier. Someone with diabetes may need to plan carbohydrate amounts more carefully. A single ingredient on a label cannot support one universal conclusion for every situation.

06 · A practical label check

1. Find maltodextrin in the ingredients list.
2. Check total carbohydrates per 100 g and per serving. The sugars figure alone is not enough.
3. Consider your actual portion size and other sources of carbohydrates in the meal.
4. If you have specific dietary needs, assess the product with a professional according to your circumstances.

Completely avoiding maltodextrin is usually not the goal. It is more useful to understand its function and make decisions based on the whole product.
