HFS55
The HFS55 syrup is partially(55%) converted from glucose to fructose, ,the sweetening power of fructose syrup is comparable to that of sucrose. so it is not only used in household diets, but also in the food industry as a substitute for granulated sugar. The mixture taste of glucose and fructose form the unique sweetness characteristics close to honey. Fructose is also the main component of honey, with the highest sweetening power among all sugars and the most soluble in water. It is widely used in almost all food enterprises in USA and China, with more than 10 million tons yearly consumption.
Process Flow Chart
Process Description
(1) Starch Slurry Preparation: adjust the concentration of starch to 17-19Be with water, and adjust the pH value and temperature.
(2) Liquefaction: Transfer the starch milk to the buffer tank, adding appropriate amount of starch enzymes, and use the jet cooker to heat and mix in order to maintain right conditions for liquefication.
(3) Saccharification: The liquefied syrup will be cooled to a certain temperature, with pH value adjustment, appropriate amount of saccharification enzyme will be introduced, then transferred to the saccharification tanks, when the saccharification reaches the needed DE value within a specified time, the saccharification process will be completed.
(4) Filtration and decolorization: The glucose syrup passes through the filters to remove protein and other impurities, then add activated carbon for decolorization within a certain time, then send it to the filters to remove the activated carbon, the filtrate will be sent to the Ion Exchange Process. (Note: activated carbon process can be eliminated when membrane filtration process applied)
(5) Ion exchange: At a certain temperature, the glucose syrup enters the cation resin and anion resin exchangers to remove inorganic salts, colorants and other organic impurities to obtain refined glucose syrup.
(6) Evaporation: The refined glucose syrup is sent to the evaporator through a safety filter to be concentrated to reach the required product concentration, and then transferred to the Isomerization process.
(7) Isomerization: The glucose syrup will be mixed with some specified chemicals, after the pH value and temperature is stabilized, it will be transferred to the isomerization column to produce fructose under the enzymatic reactions, the fructose content will reach 42% in most of the cases.
(8) Decolorization: F42 fructose syrup is mixed with activated carbon, decolorized at a certain temperature, and transferred to a filter to remove the activated carbon to obtain a clear fructose syrup.
(9) Ion exchange: F42 fructose syrup is processed into cation resin and anion resin exchangers at a certain temperature to remove inorganic salts and colorants and other organic impurities to obtain further refined syrup.
(10) Chromatography separation: F42 fructose syrup at certain concentration is degassed and then purified by a chromatography system to obtain fructose purity above 90%.
(11) Blending: F42 fructose syrup and F90 fructose are mixed in a certain proportion to get F55 fructose syrup.
(12) Decolorization: F55 fructose syrup is mixing with activated carbon, decolorized at a certain temperature, and then transferred to a filter to remove the activated carbon to obtain a clear fructose syrup .
(13) Mix bed: F55 fructose syrup at a certain temperature, will be treated by mix bed for the final refinement.
(14) Evaporation: F55 fructose syrup is sent to the evaporator through a sterilization filter for further concentration to 77%DS.
(15) Finished product: F55 fructose syrup is cooled to a certain temperature, filled and weighed, packaged and stored in the warehouse.
