5.Syrup Refining And Decolorization
Activated carbon efficiently removes impurities that affect the quality of sugar solution through the synergistic effect of physical adsorption (van der Waals forces capturing pigment macromolecules) and chemical adsorption (surface functional groups forming hydrogen bonds with pigments). Activated carbon in sugar refining is not only a "pigment catcher", but also a key node in resource recycling - from the regeneration of corn stalk waste residue to the microwave activation of bagasse, technological innovation is driving the sugar industry to leap towards green and low-carbon. In the future, with the popularization of modified carbon and intelligent combined processes, activated carbon will continue to provide underlying support for the high-quality and sustainable development of the global sugar industry.
