STARCH (Native & Modified) Starch or amylum is a carbohydrate consisting of a large number of glucose units joined together by glycosidi bonds. This polysaccharide is produced by all green plants as an energy store. It is the most important carbohydrate in the human diet and is contained in such staple foods as potatoes, wheat, maize (corn), rice, and cassava. The word "starch" is derived from Middle English sterchen, meaning to stiffen. "Amylum" is Latin for starch, from the Greek "amulon" which means "not ground at a mill". The root amyl is used in biochemistry for several compounds related to starch. Use as food additive: As an additive for food processing, food starches are typically used as thickeners and stabilizers in foods such as Turkish delights, puddings, custards, soups, sauces, gravies, pie fillings, and salad dressings, and to make noodles and pastas. Starch is also used as an excipient, a binder in medications to aid the formation of tablets.  Industrial applications: Papermaking is the largest non-food application for starches globally, consuming millions of metric tons annually. In a typical sheet of copy paper for instance, the starch content may be as high as 8%. Both chemically modified and unmodified starches are used in papermaking.  Corrugated board adhesives are the next largest application of non-food starches globally. Starch glues are mostly based on unmodified native starches, plus some additive such as borax and caustic soda. Another large non-food starch application is in the construction industry, where starch is used in the gypsum wall board manufacturing process. Chemically modified or unmodified starches are added to the stucco containing primarily gypsum. Starch is used in the manufacture of various adhesives or glues for book-binding, wallpaper adhesives, paper sack production, tube winding, gummed paper, envelop adhesives, school glues and bottle labeling.  Textile chemicals from starch are used to reduce breaking of yarns during weaving; the warp yarns are sized, especially for cotton. Starch is also used as textile printing thickener. In the printing industry, food grade starch is used in the manufacture of anti-set-off spray powder used to separate printed sheets of paper to avoid wet ink being set off.  Starch is used to produce various bioplastics, synthetic polymers that are biodegradable. An example is polylactic acid. For body powder, powdered corn starch is used as a substitute for talcum powder, and similarly in other health and beauty products.  In oil exploration, starch is used to adjust the viscosity of drilling fluid, which is used to lubricate the drill head and suspend the grinding residue in petroleum extraction. Hydrogen production can use starch as the raw material, using enzymes. |
