Kinetics and Properties Study on Cholesterol Sorption onto PDF

Abstract

Abstract: In this paper, the adsorption of cholesterol onto Potato Dietary Fiber (PDF) in ethanol was studied. The results indicated that the optimal adsorption concentration for cholesterol was 60 to 100μg/ml to 0.5 to 1.0g PDF after30 minters later, low temperature was beneficial to the adsorption, the mechanism was physical adsorption, kinetics study showed that the adsorption of PDF for Cholesterol was agreement with Freundlich equation. In conclusion, PDF has ability of adsorbed Cholesterol and may be used adsorption for Cholesterol to human body.

Key words: PDF, cholesterol, kinetics, adsorption
