The German word Starch means strong or hard or hard or rigid. Starch is a complex homopolysaccharide. Its molecular symbol is (C6H10O5)n. Carbohydrates or sugars produced in the process of photosynthesis are converted into starch and stored. Rice, wheat, potato, sorghum, banana, barley etc. are the main sources of starch. All these ingredients contain 70-80% starch. Round potato starch particles are the largest and 100µm. Rice starch particles are smallest and 2µm. The first reference to the extraction of starch from plants is found in the Natural History of Pliny the Elder (77-78 AD). Dr. Siddiq Publications
