How is glucose syrup made ?

How is glucose syrup made? Usually the raw material could be rice and all kinds of starch (corn starch, potato starch, cassava starch etc.) If the raw material is grain, such as corn, potato and cassava tubers etc, firstly extract starch slurry from raw grain, and then produce glucose from starch slurry. If the raw material is rice or starch powder, firstly mix starch with water and get starch slurry, then make glucose from starch milk.
How is glucose syrup made from starch? The procedures could be divided into several steps: starch mixing process, liquefaction process, protein-removing process, saccharification process, decoloration process, activated carbon separating process, ion exchange process and evaporation process.
Saccharification tank
Generally, how is glucose syrup made from starch consists of three main section: glucose making process, glucose cleaning and refining process, and glucose concentration process.
1st section of how is glucose syrup made-glucose making process. The process is the key procedures that converting starch polysaccharide into glucose monosaccharide by hydrolysis of enzymes. Firstly mix starch with certain volume of water and get required density starch milk. Then pump the starch milk into the liquefaction tank. By the function of jet cooker, temperature increase quickly in the tank and starch granules get rapidly swell and become transparent paste liquid, called gelatinization, which makes it more suitable for liquefaction enzymes. After liquefaction, we will get dextrin that is prepared for the next process saccharification. The saccharification process is actually create an environment that is suitable for saccharification enzymes reaction, mainly the adjustment of pH and temperature. The liquefied liquid dextrin is first adjusted with acid to adjust the pH, and then cooled down by using cooling water to obtain a suitable temperature. Finally, the saccharification enzyme is used to complete the liquefaction solution. The final hydrolysis gives crude sugar solution in the process for how is glucose syrup made.
Filter press machine
2nd section of how is glucose syrup made-glucose cleaning and refining process. In the first section of glucose making, we have got crude glucose solution. This section is mainly to purify the crude glucose and get high quality glucose as final product. Firstly is the decoloration of liquid glucose. Here activated carbon is used. Activated carbon has strong adsorption ability to organic impurities. And activated carbon is insoluble in water. After decoloration is finished, we can use filter press machine to remove the activated carbon as well as removes organic impurities from the sugar solution. Even though, there are still inorganic ion impurities exiting in the liquid. The function of ion exchange column is applied to eliminate ion impurities. By the exchange of ion impurities with H+ and OH- on columns, they will be removed in form of water.
Ion exchange column
3rd section of how is glucose syrup made- glucose concentration process. The process is also called evaporation process, which is to remove excess water from liquid glucose and get certain DS value glucose syrup. The step will use evaporator and three-effect evaporator is commonly used. Three-effect evaporator can make full use of heating steam. Usually after evaporation, the DE value of final glucose is about 80%, which is better for storage and transportation for how is glucose syrup made.
