The starch - substance is very versatile. It is possible to prepare the paste, it is possible to make a viscous substance for cooking, you can make a solution with which it is possible to give a certain rigidity to the garment. But there is another products in the food industry, which can be obtained from starch. Is glucose.
2
We all know that glucose is found in sweet fruits such as grapes and in honey. And glucose can be produced from starch. For the first time such a production has been established during the war of England against Napoleon. While many European countries were cut off from sugar-producing countries, and had to get out of the situation. Today, glucose is produced in the form of a syrup or solid, which we all know under the guise of vitamins.
3
Glucose is often called grape sugar. And get it through the hydrolysis of starch. To do this, use two industrial method of obtaining glucose from starch. This is an acid hydrolysis and partial acid hydrolysis followed by fermentation.
4
To get glucose from starch, it is necessary to heat it with the addition of diluted sulfuric acid. The surplus in the industry is neutralized with chalk. Next, the precipitate of calcium sulfate formed as a result of such heating, it is necessary to filter and work on the resulting solution. It is evaporated and through this process get glucose. But if the hydrolysis is not to finish, then formed a mixture of dextrins to glucose. And this so-called molasses, which is successfully used in the food industry.
5
And in the human body is natural production of glucose from starch. Starch with sucrose - one of the main suppliers of carbohydrates. In the body starch is undergoing a process of hydrolysis under the action of enzymes. And after that glucose is oxidized in cells to carbon dioxide and water, releasing the energy that is necessary for the functioning of the whole organism.
