Application

Starch from rice serves a versatile purpose as a natural carbohydrate obtained in powder form, notable for its neutrality in odor and taste. This starch is composed of glucose units forming two key polymers: amylose and amylopectin, which provide distinct properties advantageous in various applications. Primarily, rice starch acts as an important thickening agent in foods, contributing to texture and consistency. It is insoluble in cold water but swells upon heating, creating a gelatinous paste. In pharmaceuticals, it serves as a binder, diluent, and disintegrant in oral dosage forms, enhancing drug stability and delivery. Rice starch is specifically valued for its fine powdery form, which aids in topical applications due to its liquid absorbency. Additionally, its role extends to novel drug delivery systems and clinical nutrition, where high amylose content makes it an effective insoluble fiber for targeted nutritional therapies. Rice starch is pivotal in manufacturing processes, including extrusion and spheronization, due to its high gelatinization temperature. Thus, rice starch proves essential across diverse fields, from culinary arts to pharmaceutical innovations.
