What happens when adding maltodextrin to beer?

Maltodextrin when added to the beer enhances the mouthfeel, body, and head retention. It is a non-fermentable sugar that does not affect the fermentation of beer and just enhances the beer taste and body without altering its basic features.

Adding maltodextrin to beer:

Addition of maltodextrin to beer results in the enhancement of body, mouthfeel, and head retention of beer. It is a sugar that is non-fermentable, flavorless and colorless, and deprived of calories which are used to impart some certain features to the beer through addition in it.

The addition of maltodextrin in beer increases the level of dextrin in beer. Dextrin is a sugar that is non-fermentable and adds body to the beer as a result of which a mouthfeel develops in the beer-making it a more liked and consumed product among the consumers.

Maltodextrin, obtained from the malted grains, provides a certain flavor and aroma to the maltodextrin that when added to some other products can develop a unique taste in them. But in the case of commonly used maltodextrin, it can affect the taste to some extent but usually does not contribute to any sweetness at a significant level.

Recommended concentration:

Every addition in a product should be maintained in a specific range of quantities. The same is the case with the addition of maltodextrin in beer. There is no hard and fast rule but usually, the recommended amount of maltodextrin is 0.8-1.6 oz per gallon (1.6 – 3.2 lbs per bbl) of beer.

Beer enhancers:

Beer enhancers are substances mainly used to enhance the flavors in beer. These can be fermentable or non-fermentable ingredients or a mixture of both. Among non-fermentable beer enhancers, maltodextrin is a well-known sugar that gives the beer a unique mouthfeel and body to let the consumers enjoy it.


Maltodextrin is a sugar, a polysaccharide, used as a food additive. It is mainly obtained from the starches of different vegetables through the process of partial hydrolysis. It is usually found in the form of a white hygroscopic powder that has been dried through various drying techniques.

The process of preparation includes the hydrolysis of the vegetable starches. The method simply includes putting the starch, water, enzymes, and acids in a container. The enzymes break down the starches into smaller pieces resulting in the formation of a white powder mainly consistent with sugary molecules.

Maltodextrin is a digestible protein and can be absorbed easily just like glucose when ingested in the diet. While talking about its flavor, it is either flavorless or mildly sweet. The extent of sweetness depends upon the degree of polymerization.

Maltodextrin also acts as a preservative that can enhance the shelf life of many products. It is mainly used to lower the caloric contents of processed foods by cutting down their sugars or fats in most processed foods.
