Corn syrup production process

Jul 09, 2018 /Syrup Processing
Corn syrup production process is a process of converting corn into syrup, but actually the material used to process syrup is corn starch, although  Doing Company has mastered the technology which can use corn powder converting corn syrup directly, but if you want to produce high quality corn syrup, suggest you still used the corn starch as material to produce corn syrup. And corn syrup include the glucose, fructose and maltose, three types, use different enzyme forstarch hydrolysis can get different syrup. Then next is the brief description of the corn syrup production process:

1. Raw material preparation-corn starch making process:
Process the corn into corn starch. Corn starch specifications as below:

starch content moisture fat protein ash
85.4% 14% 0.1% 0.4% 0.1%

2. Mixing process of corn syrup production process:
The DS value of 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 suitable conditions then go to the next section.

3. Liquefaction and heating:
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. This process is important of the whole corn syrup production process.

5. Filtration and decolorization:
Corn syrup/ 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 waste activated carbon and send to the next section.

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

7. Final production storage:
Maintain the glucose syrup purity, easy for transportation. Until now, the corn syrup production process has been completed.

Corn starch is converted into ordinary corn syrup through a process called enzyme hydrolysis. In this corn syrup production process, the wet starch is mixed with a weak solution of hydrochloric enzyme and is heated under pressure. The hydrochloric enzyme and heat break down the starch molecules and convert them into a syrup. The hydrolysis can be interrupted at different key points to produce corn syrups of varying sweetness. The longer the process is allowed to proceed, the sweeter the resulting syrup. After starch hydrolysis, this syrup is then filtered or otherwise clarified to remove any objectionable flavor or color. It is further refined and evaporated to reduce the amount of water.

Quality control of corn syrup production process:


Corn syrup is primarily used as a food product. In the United States, its production and uses falls under the control of the federal Food and Drug Administration (FDA), which sets rigid quality standards. The corn refiners, working through the Corn Refiners Association, have developed comprehensive analytical procedures for testing the properties of corn products, including corn syrup, so requests the corn syrup production process must normative. Some of the important properties of corn syrup are dextrose or fructose content, carbohydrate composition, solids content, sweetness, solubility, viscosity, and acidity. In addition to monitoring the materials and processes used to make corn syrup, manufacturers also take frequent samples of the finished product for analysis. If you adopted our corn syrup production process equipment, we will equipped the quality control and checking equipment to guarantee your syrup products quality, this is essential in your corn syrup production plant.
