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 (≤ 100°C) and acid/alkaline resistance.
