The studies on drying methods and processing treatment onABM were limited. The impact of drying methods on physicochemi-cal properties and antioxidant activities of ABMP are still unknown. The aims of the present study are, therefore, to examine the chem-ical composition and antioxidant activities of ABMP treated bydifferent drying methods (air, vacuum, and freeze drying) for seeking the most proper drying method for the production of activepolysaccharides.
