Starch

In nature, starch is available in abundance surpassed only by cellulose as a naturally occurring organic compound. The most common sources of starch are corn, potato, wheat, tapioca and rice.

Corn starch is extracted from the kernel through a process of wet milling. The process employs techniques of grinding, screening and centrifugation to separate purified starch from fiber, oil and tightly bound protein. The wet milling process begins with softening the kernel by steeping it in a diluted acidic solution. Coarse grinding splits the kernel to remove the oil-containing germ. Finer milling separates the fiber from the endosperm which is then centrifuged to separate the less dense protein from the more dense starch. The starch is then washed and dried or left in a slurry for further processing.
