【Abstract】 Preparation technology of insoluble chitosan was studied that was designed for declourization and clarification of apple juice. The best preparation conditions for the insoluble chitosan were 35 % NaOH, 50 ℃, and 6 h. Its adsorptive and regeneration properties were investigated. The prepared insoluble chitosan could be regenerated and be suitable for acting as adsorbents for decolourization and clarification of juice.更多还原
