Abstract

In this experiment, agarose degradation was conducted under identical hydrolysis conditions, but different substrate and enzyme concentrations. Hydrolysis products i.e., agaro-oligosaccharide were monitored using viscometric and reducing end assay. Hydrolysis yields were found to range between 3.73 and 20.51%. Thereafter, agaro-oligosaccharides with different degree hydrolysis were subjected to various physicochemical analyses and invitro antioxidant assays. Agaro-oligosaccharides were shown to exhibit high solubility percentages (59.84-86.78%), water absorption capacities (1.5-3.0g/g) and oil absorption capacities (1.8-4.6g/g). Agaro-oligasaccharides were also shown to exhibit considerable DPPH and ABTS+ radical scavenging and ferric reducing antioxidant activities; however, this effect depended on the degree hydrolysis.
