Starch is a plant sugar store, composed of particles of glucose produced in the process of photosynthesis (α-D-glucoses linked by α-1,4-glucosidic bonds), and is equivalent to the animal glycogen; belonging to the groups of basic carbohydrates. It consists of amylose and amylopectin. It is insoluble in water, after soaking swells making better filling of the gastrointestinal tract and reduces hunger. During the heating the gelatinization starch takes place. Starches can be divided into: native (achieved e.g. potato, corn, wheat) and wax (e.g. In the waxy maize). Native starch used in the starch production (stiffening agent) and puddings and jellies. The waxy starch amylopectin prevails.
