Corn starch
 |
Cornstarch, or cornflour, is the starch of the maize grain, commonly known as corn. It is also ground from the endosperm, or white heart, of the corn kernel. It has a distinctive appearance and feel when mixed raw with water or milk, giving easily to gentle pressure but resisting sudden pressure (see Non-Newtonian fluid). It is usually included as an anti-caking agent in powdered sugar (10X or confectioner's sugar). For this reason, recipes calling for powdered sugar often call for at least light cooking to remove the raw cornstarch taste.
Amylophagia is a condition involving the compulsive consumption of excessive amounts of purified starch, often cornstarch.[1]
Uses
Cornstarch is often used as a binder in puddings and similar foods. Most of the packaged pudding mixes available in grocery stores include cornstarch. Cornstarch puddings may be easily made at home, benefiting from the use of a double boiler. The most basic such pudding may be made only from milk, sugar, cornstarch and a flavoring agent.
It is also used as a thickener in many recipes. Cornstarch is best dissolved in cold water, as it forms obstinate lumps when mixed with warm or hot water.
Cornstarch also has many uses in the manufacturing of environmentally-friendly products. For example, in 2004, the Japanese company Pioneer announced a biodegradable Blu-Ray disc made out of cornstarch. [2]
Cornstarch has been used as a replacement for talc in baby powder.
A mixture of 1 parts water to 1.5–2 parts cornstarch is a popular classroom demonstration of a dilatant (shear-thickening) fluid. When struck, cut with a knife, or worked vigorously in the hands, it behaves like a pliable solid, but if allowed to sit for a few seconds, it flows as a viscous liquid.
Other names
In Britain, Australia, parts of Canada, Asia and most of the Commonwealth, this substance is known as cornflour.
