There starch, corn starch and a variety of modified starch into two categories widely used in food and industrial. Food use corn starch is widely used in food formulations, such as baked goods, also small food and cassava extruded beads used in the production. Starch or starch derivatives have been used as a thickener, binder, bulking agent and stabilizer, it is the best extenders, sweeteners, flavoring carrier and fat substitutes. Use Thai tapioca starch foods, including canned food, frozen food, dry mix food, baked goods, snack foods, condiments, soups, sausages, dairy products, meat and fish products, and baby food. Beverage starch as a colloidal stabilizer in beverages containing solid ingredients. In beverages, corn starch sweetener than sugar, because the former improves the process and strengthen the product features, combined with other sweeteners, can fully meet consumer demand. High degree of hydrolysis of corn starch hydrolyzate syrup form is brewing in an ideal source of readily fermentable sugars. Candy corn starch and a variety of modified starch in the candy production has many uses, such as gelling, thickening, stabilizing system, enhanced foam, controlled crystallization, bond, film, adding gloss. Low viscosity of cassava starch is widely used in gum candies, such as jelly and gum. The most commonly used is the acid hydrolysis of starch, because it has excellent reversibility and gelling ability, the case of sugar, the more significant of these features. Dry starch is used as a release agent in candy making. Polysaccharide starch-based sugar-free gum to achieve a production. Chemical corn starch-based syrup by acid hydrolysis or enzymatic hydrolysis process to achieve low-cost production, which as a raw material for the production of various chemicals, such as sodium glutamate, amino acids, organic acids, alcohol, ketones, vitamins and antibiotics. Corn starch dextrin adhesives and glue is an excellent adhesive, widely used, including corrugated cardboard, paper, plywood, adhesive tape, adhesive tape, labels, stamps and envelopes. Papermaking modified starch used in paper industry to improve paper quality, increase productivity and pulp utilization. Cationic starch for flocculation of pulp and improve the efficiency of dehydration wet, you can use a higher machine speed and higher pulp utilization. It remains in the finished paper starch as an internal sizing agent to increase paper strength. Low viscosity starches such as oxidized starch, ink receptivity used as surface sizing agent to improve the paper strength and improve printing and writing time. Starch is also used as an adhesive coating pigments to produce a smooth, white high-grade paper. Textile in the textile industry in order to improve the efficiency of the textile, corn starch is often used as a sizing agent to harden and protect the yarn; used as a finishing agent to produce smooth feel of the fabric; the toner used in order to obtain a clear, wear-resistant cloth material . For textile use mild cooked starch better results. Biodegradable material corn starch and modified starch can be mixed with petroleum-based or synthetic polymer materials to improve material is biodegradable, so that the production cost of such environmentally friendly materials to a minimum.
