Modified starches are used in practically all starch applications, such as in food products as aor ; in as a ; or as binder in. They are also used in many other applications. Starches are modified to enhance their performance in different applications. Starches may and modified to increase their stability against excessive starch, acid, shear, time, cooling, or freezing; to change their ; to decrease or increase their ; to lengthen or shorten time; or to increase their. Modified starch may also be a cold-water-soluble, pregelatinized or instant starch which thickens and gels without heat, or a cook-up starch which must be cooked like regular starch. Drying methods to make starches cold-water-soluble are, or. Other starch derivatives, the starch sugars, like, starch degraded with are mainly sold as use to make a. Pre-gelatinized starch is used to thicken instantallowing the food to thicken with the addition of cold water or milk.

Genetically modified starch is of interest in the manufacture of and noncellulose feedstock in theas well as the creation of new. For example, researchers aim to alter the enzymes within living plants to create starches with desirable modified properties, and thus eliminate the need for enzymatic processing after starch is extracted from the plant.
