How to make corn syrup from corn starch ?
2018-08-20 / FAQ
Starch is the main raw material to make glucose syrup. All kinds of starch, such as cassava starch, potato starch, sweet potato starch, wheat starch and corn starch etc., can be used as raw material in glucose syrup production. Compared with other starch, corn starch is the best for glucose making. If one have enough supply of corn starch, he may ask "how to make corn syrup from corn starch".
Procedures for how to make corn syrup from corn starch mainly divided into three parts: raw material selection and mixing process, liquefaction and saccharification process, refining and purification process, evaporation and concentration process. In short, the process of glucose making is the process that starch is hydrolyzed into glucose unit molecule.
Corn starch is a good material to produce syrup
How to make corn syrup from corn starch? The first and important one is the raw material selection. To make high quality glucose syrup, you need to make sure the high quality of raw material. Protein content and other impurities should be controlled as low as possible. That's to say the corn starch quality directly influenced the syrup quality.
The process of make corn syrup out of corn starch
Next part is the liquefaction process, which can be divided into three sub-steps: starch slurry mixing→1st jet cooking→temperature maintenance→2nd jet cooking. Firstly mixing starch and certain water to get the certain density slurry, then adding enzyme and adjusting pH value. Then the liquid will go to the 1st jet cooking. 1st jet cooker increases the temperature to about 110, the starch particles quickly absorb water and swell into a transparent paste-like liquid, known as gelatinization, making it more suitable for the liquefaction enzymes; After gelatinization, the temperature is maintained at about 95 for 90-120 minutes, so that the starch slurry was fully liquefied; 2nd jet cooker increases the temperature to around 135, which caused all previously added liquefaction enzymes eliminated. About the question how to make corn syrup from corn starch, this liquefaction process large influenced the speed.

After liquefaction process, we will get liquid dextrin. Liquid dextrin which has been through temperature ejection shall move into filter process for mechanical extrusion. Filter press will separate protein and other solid impurities from liquid dextrin. After that, adding enzyme into the liquid and it starts saccharification reaction inside saccharification tank for the process in the answer for how to make corn syrup from corn starch.
In the refining and purification process, protein removing is the first step to remove protein and other solid impurities. After saccharification process, we need to make liquid glucose as transparent as possible. Usually activated carbon will be used in decolorization process. After that, waste activated carbon must be separated from liquid glucose by filter press machine. To complete decolorization thoroughly, the normal sequence is: 1st decolorization →1st decarburization→2nd decolorization →2nd decarburization. This part directly influence the syrup taste to answer how to make corn syrup from corn starch.

In above process of how to make corn syrup from corn starch, protein and other solid impurities, colored organic impurities, waste carbon etc. are eliminated chronologically. But there are anions and cations left in the liquid glucose. To finish last step of refining and purification process, ion exchange column is applied. The cation in the sugar liquid exchanges with the H+ on the cation exchange resin, the anions in the sugar liquid exchanges with the OH- on the anion exchange resin, and finally the H+ and OH- exchanged into the sugar liquid combine into water, and the sugar liquid inorganic impurities have become the corresponding amount of water removed.

Next is the last step to the answer for how to make corn syrup from corn starch. After refining and purification process, we get purified syrup liquid. In order to obtain the desired density of syrup, excess water is evaporated in the following process, which is called evaporation and concentration process. Three-effect evaporator is applied here to remove excess water. The final DS value we get finally is normally between 75-82%, which is the best state for storage.
How to make corn syrup from corn starch? To sum up, the procedures are: starch slurry mixing→liquefaction→deproteinization→saccharification→decolorization→decarburization→ion exchange→evaporation.
