Sugar can be got in several ways: from plants, by means of chemical industry. And here such option of sweet as glucose, it is possible to receive from usual starch.
Instruction
1. Starch - substance very multipurpose. From it it is possible to prepare paste, it is possible to make viscous substance for cooking, it is possible to make solution by means of which it is possible to give a certain rigidity to clothes. But is also one more products in the food industry which can be received from starch. It is glucose.
2. All of us got used that glucose meets in sweet fruit, for example, in grapes and also in honey. And still glucose can be extracted from starch. For the first time such production was arranged even at the time of war of England with Napoleon. Then many European countries were cut off from producing countries of sugar, and it was necessary to find a way out somehow. Today glucose is produced in the form of syrup or solid substance which all of us know under the guise of vitamins.
3. Glucose is often called glucose. And it is possible to extract it by means of conversion. For this purpose apply two industrial ways of receiving glucose from starch. It is acid hydrolysis and partial acid hydrolysis with the subsequent fermentation.
4. To receive glucose from starch, it is necessary to heat it with addition of the diluted sulfuric acid. Its surplus in the industry is neutralized chalk. Further that deposit of sulfate of calcium which was formed as a result of such heating it is necessary to filter and work further with the turned-out solution. It is uparivat and by means of this procedure receive glucose. And here if not to finish hydrolysis, then mix of dextrins with glucose is formed. And it is so-called treacle which with success is applied in the food industry.
5. And in a human body there is a natural production of glucose from starch. Starch together with sucrose - some of the main suppliers of carbohydrates. In an organism starch passes through the procedure of hydrolysis under the influence of enzymes. And further already glucose is oxidized in cages to carbon dioxide and water, emitting at the same time energy which is necessary for functioning of all organism in general.
