How is HFCS high fructose corn syrup produced ?

Fructose corn syrup also called high fructose corn syrup or isomer syrup. Its process mainly raw material is starch, so any raw grains contain starch can be the raw material to produce high fructose corn syrup, like corn, rice, potato, cassava. The How is HFCS high fructose corn syrup produced, actually it is produced by the glucose isomerism to change part of glucose into fructose, its manufacturing process is according to the enzyme method to saccharify starch, then the saccharification solution under the isomerism enzyme process change the glucose into fructose.

On the following use the starch for example to answer the question how is HFCS high fructose corn syrup produced. High fructose corn syrup manufacturing process mainly include three section, that is starch liquefaction, saccharification and isomerism process. The high fructose corn syrup detail produced process flowchart as below:

High fructose corn syrup produced process

Liquefaction:

Starch slurry mixed with 30-35% dry solids and adjust its PH value to 6.0-6.4. Before put into α-enzyme, first add calcium, because calcium ions can stabilize the enzyme. Then mixed heat-stable α-enzyme (Novo’s Termamyl 120L) into the starch slurry, the slurry is instantaneously heated to 100 ℃ and held at this temperature for 10 min before it is cooled to 90 ℃. This temperature is maintained for 1-3h service for further hydrolyze the starch. This process directly decided the yield of the high fructose corn syrup, also can understand this as the starch using rate of the answer for how is HFCS high fructose corn syrup produced.

Liquefaction process technical parameters:

After this liquefying process complete of the how is HFCS high fructose corn syrup produced, the starch has been transfered into dextrins with a dextrose equivalent (DE) between 15 and 20. (The physical properties of thesyrup changed with the DE and the method of manufacture difference.) DE is the total reducing sugar in the syrup expressed as dextrose on a dry weight basis.

Saccharification process introduction:

After liquefaction, the pH value is reduced to between 4.2 and 4.5, after the solution is cooled to 60 ℃. Added the glucomylase (Novo’s AMG 300L) immediately. The reaction time for saccharification is usually between 24-48 hour depending on enzyme reaction speed. Glucoamylase releases single glucose units from the ends of dextrin molecule. Syrups of 95% glucose or higher are manufactured. This is the saccharification process for the F42 high fructose corn syrup manufacturing process. This section high influenced on the flavour of the high fructose corn syrup. Also an important part in the answer for how is HFCS high fructose corn syrup produced.

Saccharification process technical paramters:

It's worth to tell you the liquefaction and saccharification step is the most important two parts of the high fructose corn syrup manufacturing. These steps performance influenced the glucose products quality directly. So the advanced technology and equipments is very important. All in all, when you asked how is HFCS high fructose corn syrup produced, except the technology process, you also need to concenrn the equipments quality.

Isomerism:

The purified glucose solution is isomerized by a reactor containing immobilized isomerase to obtain fructose syrup with 42% fructose content. It's honor to tell you that the isomerase we are using is a kind of immobilized enzyme. Converted from soluble state into immobilized state, the stability of isomerism will be increased significantly and it can be uses repeatedly in the high fructose corn syrup produced. This immobilized enzyme used in food processing make food free of enzyme after production, so there is no need to adopt the way of heat treatment to make enzyme inactivated, which can help improving the quality of food as well as economic benefits. This is our advantages of Doing Company technology answer for the how is HFCS high fructose corn syrup produced.

For another, if you want to get the F55 or F90 HFCS, just use the F42 as basic material to produced is a high efficiency and convenience method. After F42 high fructose corn syrup manufacturing produced, add the crystallization system and refining system can produced F90 high fructose corn syrup. And to produce F55, just mixed F90 with F42 with a suitable proportion. To sum up, among is the introduction of Doing Company answer for how is HFCS high fructose corn syrup produced, we can offer technology and equipments, give you complete high fructose corn syrup produced equipments, F42, F55, F90 all is suitable.
