Romans used it also in cosmetic creams, to powder the hair and to thicken sauces. The extraction of starch is first described in the Natural History of Pliny the Elder around AD 77–79. Pure extracted wheat starch paste was used in Ancient Egypt possibly to glue papyrus. Starch grains from sorghum were found on grind stones in caves in Ngalue, Mozambique dating up to 100,000 years ago.
Starch grains from the rhizomes of Typha (cattails, bullrushes) as flour have been identified from grinding stones in Europe dating back to 30,000 years ago. It provides the root amyl, which is used as a prefix for several 5-carbon compounds related to or derived from starch (e.g. The Greek term for starch, "amylon" (ἄμυλον), which means "not milled", is also related. Modern German Stärke (strength) is related and referring for centuries main application, the use in textile: sizing yarn for weaving and starching linen. The word "starch" is from its Germanic root with the meanings "strong, stiff, strengthen, stiffen".
§ Clothing starch can be applied to certain textile goods before ironing, to stiffen them. The greatest industrial non-food use of starch is as an adhesive in the papermaking process. Mixing most starches in warm water produces a paste, such as wheatpaste, which can be used as a thickening, stiffening or gluing agent. It is processed to produce many of the sugars used in processed foods. In industry, starch is converted into sugars, for example by malting, and fermented to produce ethanol in the manufacture of beer, whisky and biofuel. Glycogen, the energy reserve of animals, is a more highly branched version of amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. Worldwide, it is the most common carbohydrate in human diets, and is contained in large amounts in staple foods such as wheat, potatoes, maize (corn), rice, and cassava (manioc). This polysaccharide is produced by most green plants for energy storage. I’ve made a couple of different origami flowers before (you can find my origami tulip here and my origami lotus here) but I think you’ll love how quick and easy these are compared to how intricate they look.Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds.
