Activated Carbon for Citric Acid Decolorization: Why Wood-Based Powder Carbon Is Commonly Used

Citric acid production often requires decolorization and impurity removal after fermentation and purification steps. Wood-based powdered activated carbon is commonly used because it provides strong decolorization performance, fast adsorption, and good compatibility with liquid-phase food and fermentation processes. Selecting the right activated carbon grade can help improve solution clarity, reduce color bodies, and support stable final product quality.
Wood Powder Activated Carbon for Erythritol Purification

Wood powder activated carbon is widely used in erythritol purification to remove color bodies, organic impurities, odor substances, and trace by-products generated during fermentation and downstream processing. With its developed pore structure and strong decolorization performance, wood-based powdered activated carbon helps improve the clarity, purity, and appearance of erythritol solutions.
