rice starch

Rice starch is a carbohydrate derived from rice grains, primarily used in laundry work. It is typically prepared from broken white rice. The process involves steeping the grains in a caustic soda solution, followed by washing, grinding, and then settling or centrifuging to separate the starch. The starch liquor is dewatered, washed, and dried into crystals.1

Starch, in general, is a white, granular organic chemical produced by green plants as a reserve food supply. Its basic chemical formula is (C₆H₁₀O₅)_n. Starch is a polysaccharide composed of glucose monomers and is stored in various plant parts, including the seeds of rice. It serves as a major source of carbohydrates in the human diet, providing energy. Beyond food, starch and its derivatives have significant industrial applications in paper, textile, and adhesive manufacturing.23
