Dextrins are polysaccharides formed by heating dry or acid-modified starches in a process called pyrolysis. They can be used at higher solids levels than native or modified starches, creating stronger bonds, more tack and faster-drying properties than pastes made from unmodified starch. Dextrin pastes provide excellent machinability and also can be used in adhesives and coatings that come into contact with food products, child-safe school pastes, remoistenable wallpaper, bag/envelope seams and paper and textile sizing. Dextrin can also be used for encapsulation or granulation of active ingredients such as pharmaceuticals that are produced by fermentation.
