The production of high fructose corn syrup

2018-10-06 /Industry news

From 1950 onwards, the production of high fructose corn syrup was processed by fermentation of glucoamylase to give a DE value of 95-97. This syrup is quite sweet and contains fermentable sugars at a higher ratio than other corn syrups, mainly for fermentation production, such as bread and alcohol. Because of its high glucose content (up to 95%), it can be used as a commercial glucose crystal for food.

Conversion of glucose to fructose syrup, the sweetest glucose product obtained from starch by the above method has a sweetness of about 70 - 75% of sucrose, so other methods for increasing the sweetness of corn syrup are sought. Because fructose (levulose) is much sweeter than its isomer dextrose (glucose). Now, the enzyme method used for the production of high fructose corn syrup has been the most convenient method, and Doing Company has mastered the mature technology for high fructose corn syrup production and the equipment design and manufacturer, you can click high fructose corn syrup manufacturing process to get more information.

In a continuous process for the production of high fructose corn syrup, corn syrup containing glucose is passed through a reactor containing a solid phase enzyme to convert about half of the glucose into fructose.

There are two basic principles of enzyme immobilization technology for the production of high fructose corn syrup:

1. The sugar mold is cultivated under deep aeration conditions. The fermented mash of the can is adjusted to pH and heated to fix the glucose isomerase in the bacteria for the production of high fructose corn syrup. Filter and wash with water. The filter cake is dried and pumped into a pressurized blade filter with a mixture of glucose, MgSO4 and NaHSO3 containing corn starch hydrolysate until each leaf is coated with a solid phase enzyme preparation having a thickness of 2.54 to 3.81 cm. The filter acts as a reactor.

2. Glucose isomerase is adsorbed onto DEAE----cellulose or other adsorbent. This powder is filtered on a pressurized vane filter which acts as a reactor. Corn syrup was pumped into the reactor to control the flow rate to 45% glucose conversion to the sugar. When the activity of the solid phase isomerase preparation is gradually decreased, the flow rate is gradually reduced, so that glucose still has 45% of the converted sugar.
To sum up, for the production of high fructose corn syrup, the enzyme used in three sections: starch slurry mixing and liquefaction, saccharification and isomerism process.

Finished syrup

High fructose corn syrup (HFCS) features and applications: High fructose corn syrup is milky white. The syrup with a solid content of 71% contains about 42% fructose and 50% glucose and a very small amount of polysaccharides. Representative analysis data proves that In addition to higher sweetness, the HFCS has better fermentability, large hygroscopicity, low viscosity, refreshing taste and no odor. Due to its low viscosity, it is difficult to crystallize, it is easy to transport and store, and it is easy to mix with other syrups. When the temperature is maintained at 27 to 32 ° C, it is easily transported by a pump and can be stored for a long time without crystallization and fermentation.

In addition, high acidity foods will convert all of the sucrose contained during processing and storage, in this case, the production of high fructose corn syrup can be used to minimize conversion. At the same time, since high fructose corn syrup is a low molecular weight monosaccharide, it penetrates into the cell wall of fruits or vegetables faster than sucrose, so high fructose corn syrup can be used in the production of sweet kimchi and related foods, taste better. Since low molecular weight sugars contain less fruit and other aromas than high molecular weight sugars, the use of high fructose corn syrup in some foods can reduce the amount of perfume.

In fact, in many foods, high fructose corn syrup (HFCS) can replace sucrose and invert sugar, except those that require solid sweeteners and less satisfactory use on certain foods. This decided that the production of high fructose corn syrup has large profit because of high fructose corn syrup widely application in food industry.

Examples of high fructose corn syrup successfully applied to commodities are as follows:

1. Carbonated beverages: High fructose corn syrup can be used as a sweetener in part or in whole.

2. High fructose corn syrup can be used as the sole sweetener for base syrups and aroma concentrates for carbonated beverages; for non-foamed beverages, high fructose corn syrup can be used with glucose or high DE value corn syrup.

3. In soy sauce, high fructose corn syrup can be used and the DE value of corn syrup can be increased.

4. Salad dressings can be used alone with high fructose corn syrup or with other syrups to make.

5. Yeast fermented baked food: high fructose corn syrup can be used alone or in combination with other corn syrups. High fructose corn syrup can increase fermentability and residual sweetness and form a brown color of baked goods. Other baked goods that use high fructose corn syrup are pastries, fig cakes, and cookies.

The quality of the above products is at least comparable to that of sucrose or invert sugar, this means the production of high fructose corn syrup and application is successful. Doing Company is a good high fructose corn syrup production equipment manufacturer and supplier, if you plan to start a high fructose corn syrup production business, we will be a good supporter.
