Dextriner

Dextrin is a complex carbohydrate, a type of polysaccharide, that is produced by the partial hydrolysis of starch. It is a white, powdery substance that is soluble in water and forms viscous solutions. Dextrin is used as a food additive and has various industrial applications.

Dextrin is derived from starch by the action of heat, acid, or enzymes. This process breaks down the long chains of glucose molecules in starch into shorter chains, resulting in a mixture of different dextrin molecules. The most common types are white dextrin, yellow dextrin, and British gum. The structure consists of glucose units linked by α-1,4 and α-1,6 glycosidic bonds.

In the food industry, dextrin is used as a thickener, binder, and texturing agent. It is often added to sauces, gravies, and processed foods to improve consistency and stability. It is also used as a coating for tablets and capsules in the pharmaceutical industry to control the release of medication. Dextrin is also used as an adhesive in the paper and textile industries.

Dextrin has several important properties. It is non-fermentable by yeast, which makes it useful in baked goods where a non-fermenting, stable texture is desired. It has a neutral taste and is generally considered safe for consumption. Dextrin solutions are clear and can be used to create films or coatings due to their adhesive properties.

The production of dextrin has a long history, dating back to ancient times when it was used as a food thickener. Modern industrial production involves the controlled hydrolysis of starch from sources like corn, wheat, or potatoes. The resulting dextrin is then purified and processed into various forms for different applications.
