Starch
Starch is a biochemical agent extracted from plants; it is extracted from grains such as corn, rice, wheat, barley, or from tubers like potatoes. It belongs to the carbohydrate group and consists of long chains of amylose sugar and amylopectin sugar to be the starch polymer, one of the most complex polysaccharides with the longest carbon chains in organic chemistry, and the chemical formula for starch is: (C6H10O5 n).
All starch varieties contain 98% starch and the rest are protein, sugar and other ingredients. Starch White powder is a little soluble in cold water and water is turbid to be deposited but it is fast soluble in hot water, and gelatin gel material will quickly dry up and become solid down temperature. The most starch producing countries are the United States of America, Canada, Australia and Japan.
Benefits of starch
Starch of complex sugars is the structure that is digested in more than one part of the digestive system. The first stage occurs in the mouth where the alpha-amylase secretion is produced. The second stage in the small intestine is converted into a double sugar by the alpha-amylase enzyme in the intestine. Binary sugar to simple sugar in the small intestine is easy for the body to absorb and use in the biological processes by a group of enzymes, such as enzyme scrazase and enzyme lipase.
Starch Uses
- Man used starch to strengthen flax seeds more than two hundred years before Christ.
- Starch is the main ingredient in the manufacture of bread, pasta and biscuits.
- Starch is used in the food industry as an adhesive for ingredients due to its gels status at high temperatures.
- Starch enters into many industries such as paper industry, carton making, packaging and packaging.
- Starch is commonly used in the pharmaceutical industry and in chemical analysis laboratories. The samples to be subjected to chemical analysis using the devices are diluted with a calculated amount of starch and then compressed and placed in the radiometer.
Benefits of starch for humans
- Starch is a high-calorie compound. It provides the cells with the energy needed to complete its vital processes. Cereals such as corn, rice, wheat, potatoes and sweet potatoes are available.
- Starch makes some kinds of sweets such as milk, which supplies the body with the necessary energy, especially in the winter.
- Starch helps to get rid of excess fatty secretions in the scalp; by scattering the starch on the scalp and leave it for a quarter of an hour to absorb fat, and then wash the hair.
