Activated Carbon For Wine Decolorization And Purification
Introduction In modern brewing and food processing industries, the decolorization process often involves multiple solvent systems. Ethyl acetate, ethanol, methanol, water, and butanol — as common extractants or reaction mediums — exhibit different physicochemical properties. In such a complex multi-solvent environment, an ideal decolorizing material must have strong adsorption capacity, excellent chemical stability, and selectivity. Wood Powdered Activated Carbon: A Scientific Solution for Wine Decolorization Unique Porous Structure Advantages The excellent performance of wood powder-activated carbon in a multi-solvent system lies in its unique graded micropore-mesopore-macropore structure: Micropores (< 2 nm): Efficiently adsorb small-molecule pigments and impurities. Mesopores (2–50 nm): Major contributors to the capture of medium molecular weight pigment molecules. Macropores (> 50 nm): Serve as transport channels, ensuring rapid ingress and egress of both solvent and pigment molecules. High-quality wood-activated carbon, after high-temperature activation and deep purification, forms a stable surface with chemical properties that will not decompose or release impurities in acidic, alkaline, or organic solvent environments. This ensures that the decolorization process does not introduce new contaminants.
