摘要

An alumina/β-cyclodextrin composite adsorbent (ACDC) was prepared using neutral alumina and β-cyclodextrin (β-CD) as raw material and characterized by SEM, FTIR, TGA, and XRD. The results showed that ACDC was stacked in an ordered layered manner with significantly improved thermal stability. The cholesterol adsorption kinetics and isothermal adsorption experiments revealed that ACDC’s cholesterol adsorption behavior followed the Freundlich isotherm models and the pseudo-second-order kinetic with a maximum adsorption capacity of 88.26 mg/g. The adsorption process was primarily physical and multi-layered. Response surface methodology optimized the optimal cholesterol removal conditions from fish oil as a ratio of adsorbent to fish oil of 13%, adsorption temperature of 47 ℃, and time of 1.3 h, achieving a cholesterol removal rate of 65.19%. This rate was significantly superior to individual components and their physical mixture. In addition, ACDC had no significant effect on the nutritional quality of fish oil. This study demonstrated that ACDC holds potential as a cholesterol-removing agent in fish oil processing.
