Manufacturers produce corn syrup by removing corn starch from the grains of corn and using acid hydrolysis to convert the starches to dextrose, a simple sugar that is less sweet than table sugar.

Further refining with decolorization by activated carbon and  purity by Ion exchangers , at last use the evaporator to increase the DS of corn syrup to the buyer requirement .


The corn syrup production process is as below :

1. Corn starch making process of corn syrup production process:
Use the traditional wet milling method to making corn starch from corn .

2. Mixing process of corn syrup production process:
The DS value of the corn starch that came from corn starch making process is adjusted to 28-32% and control a proper value of PH and temperature. Or adding a certain amount of water to achieve the above conditions then go to the next section.

3. Liquefaction and heating of corn syrup production process:
Starch milk is sent to buffer tank then liquefied by jet cooker with the aid of enzyme.

4.Saccharification process:
The liquefied material keeps reaction for a certain time under the action of enzyme. The required DE value of the glucose will be produced. Then the material is sent to the enzyme killer to kill the enzyme.

5.Filtration and decolorization:
Glucose gets through the filter to remove protein and other impurities, then at the appropriate temperature passes by active carbon to decoloring, finally send to filters to remove activated carbon and send to the next section.

6 .Evaporation:
The glucose is totally cleaned through safety filter machine then sent to evaporator for concentrating to reach the required DS as final product.

7. Final production storage:
Maintain the glucose syrup purity, easy transportation.
