(C H O ) also know as Corn Starch or 6 10 5 n Corn flour is a fundamental ingredient in
most of the packaged food and industrial products; it is extracted from the corn
kernel and has a distinctive appearance and feed . Maize starch in natural ,modified, pregeletanized and dextrinized forms provides viscosity, texture and other desired properties to all types of food & paper, products from canned chilled frozen to microwaveable goods, dry mixes and extruded snacks. Practically every industry in existence uses Starch or its derivatives in one form or another.
Functional Advantages
Thickening & Gelling agent
Maize Starch is most commonly used as a thickening and gelling agent for puddings
sauces soups , etc it provid e s a n economical and reliable substitute to other
ingredients which are unstable at higher temps.
Texture and clarity
Corn Starch helps in achieving the right degree of clarity structure and mouth feel.
It is also used to achieve chewiness in gums. They are equally useful as molding
powders and as ingredients of paste food.
Binder & stabilizer (Exciepient)
Corn starch is an effective binder as it allows homogenous dispersion of water in
foodstuffs, and acts as a stabilizer. It is an ingredient of choice (along with other
modified Starches) in the manufacture of soups salad dressings bakery products,
various desserts. It is a binder and filler or choice in the pharma industry for tableting
on the application. It acts diluents disintegrating agent.
Sizing- paper and Textiles
Native Starch is used to provide dry strength and as a surface improvement aid
in alkaline papermaking, Starch is a critical part of wet-end sizing it is an integral part of micro-particle retention and works as a binder water holding agent and carrier for
surface sizing chemicals and other
Bio-Plastics
Since the Starch is totally biodegradable in a wide variety of environments it allows for the development of totally degradable products for specific market needs. Bio
plastics from renewable origin are a new generation of plastics able to significantly reduce the environmental impact in terms of energy consumption and green-house effect in specific applications. Bio plastics perform as traditional plastics when in use and are completely biodegradable within a composting cycle. Examples fast food service-ware (cups, cutlery, plates straws, etc.) packaging (soluble foams for industrial packaging, film
wrapping, laminated paper, food containers)Agriculture (much films, nursery pots, plant labels) Hygiene (diaper back sheet, cotton swabs).
Handling and Storage
Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risks. Ground all equipment containing material Do not breathe dust. Keep away from incompatible(s) such as oxidizing agents. Keep container tightly closed. Keep container in a cool well ventilated area. Do not store above 230 C.
functional additives. In the manufacture of textiles Starch keeps the yarn straight and
strong significantly improving its ability to chemical's withstand the stress of weaving.
Corn Sweeteners
Native corn Starch forms the basic ingredient for all corn sweeteners. A variety of enzymatic and acid-catalyzed processes are used for the manufacture of corn sweeteners which are used in food to provide clean sweet taste retain moisture,
clean sweet taste retain moisture control crystallization and freezing points, contribute to texture provide gloss maintain color inhibit spoilage and modified density. Corn sweeteners are a major commodity and include products such as Sorbitol, Malto -Dextrins, Glucose syrups, dextrose, high maltose syrups, etc.
Ethanol
Corn Starch is an economical fermentation feedstock to produce many organic chemicals The most widely know bio product is ethanol it is made by fermenting sugars produced from corn Starch ethanol produced from corn Starch promised a renewable source of fuels for care and other engines with environmental advantages.
CycloDextrines
Another fascinating type of compound produced from corn Starch by the action of
a cyclodextrin-transglycosylase enzyme is the cyclodextrins (Shardinger dextrin's
cycloamyloses) cyclodextrins stabilize substance's that are degradable or
sensitive to light heat oxygen and ions reduce volatility and bad odor transform
viscous oily liquids to stable flowing powders enhance solubility and bioavailability provide retarded effect by slow release: remove unwanted flavors in juices and beverages. These properties would be usefulinthe fields of pharmaceutical's processed Food's cosmetic's Toiletries and Agro-chemical's.
