Recent Advances in the Adsorption and Mechanisms of Colored Substances in Sugarcane Juice: A Review
摘要
Historically, the production of white sugar from sugarcane has been marred by challenges like unsanitary conditions, excessive chemical use, suboptimal quality and yield, and high energy demands. These issues starkly contrast with modern sustainability principles, economy, and environmental consciousness. Green sugar clarification and decolorization techniques, especially adsorption-based method, have demonstrated superior efficiency in removing impurities and pigments while reducing chemical and energy requirements and simplifying operational procedures, making it a remarkably effective method. This review compares the advantages of adsorption process over conventional sugar production techniques with respect to color-forming impurities in sugarcane juice, and highlights recent applications of adsorption in the decolorization of sugarcane juice. In addition, this review explores the theoretical basis on adsorption and mass transfer with the objective of providing a comprehensive theoretical framework and detailed parameters for future color removal in sugarcane juice processing.
