Abstract

In this work oven-dried freeze-dried and spray-dried agaro-oligosaccharide powders were characterized to investigate their physicochemical and antioxidant properties. Agaro-oligosaccharide powders were shown to exhibit high water solubility index (88.73 “ 95.88) water absorption capacity (0.96 “ 2.57 g/g) and oil absorption capacity (0.40 “ 0.45 g/g). Agaro-oligosaccharide powders were shown to possess moderate DPPH radical scavenging activity (10.65 “ 14.59) ABTS radical scavenging activity (44 .47 “ 65.61) and ferric reducing antioxidant activity (0.165 “ 0.353). Agaro-oligosaccharide powders were further characterized with respect to thermal and pH stability. Agaro-oligosaccharide powders were shown to exhibit high temperature resistance ( 100oC) and acid/alkaline resistance.
