How to produce glucose syrup from starch ?

Glucose syrup processing plant

Glucose syrup, also known as candy glucose, is a kind sweet syrup made from the hydrolysis of starch. Maize /corn  is commonly used as the source of the starch ,so the glucose syrup is called "corn syrup" . But glucose syrup is also made from other kind starch, such as cassava starch , potato starch ,wheat starch and so on .

Then , how to produce glucose syrup from starch in glucose syrup processing plant ?

The production process of glucose syrup from  starch in modern glucose syrup processing plant is as below : 

(1) Starch milk adjustment
Starch milk coming from starch plant is adjusted to DS28-32% and proper pH and temperature. Or mix the dry starch with water to reach above condition for next section.

(2) Liquefaction
Starch milk is sent to buffer tank then liquefied by jet cooker with the aid of enzyme.

(3) Saccharification
The liquefied material is sent to enzyme saccharification tank for reaction. After being kept in holding tube the required DE value of the glucose will be reached. Then the material is sent to flash for cooling then to the neutralization tank for suitable pH value.

(4) Filtration and decoloring
Glucose is cleaned by removing the protein and other foreign items in rotary vacuum filter and filter press. Active carbon is needed for decoloring at proper temperature.

(5) Ion exchange
Tiny foreign items and bad odor is removed via ion exchanger. This equipment is used for high quality product.

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


In the world , all the corn glucose syrup processing plant use  corn to make corn starch first  , then use the corn starch to produce the glucose syrup . But now our company has the new technology , we can produce the glucose syrup from corn directly . It can save much cost than the corn to starch and starch to glucose technology.
