Abstract
We report the first hydrothermal hydrolysis of curdlan, a water insoluble β-1,3-glucan, to produce β-1,3-glucooligosaccharides, which are high-value materials with health-benefiting activities. In this study, hydrothermal hydrolysis was tested for the liquefaction and saccharification of curdlan. The optimal hydrothermal hydrolysis conditions were 180 °C and 60 min, respectively, resulting in a high degree of liquefaction (98.4%) and low byproduct formation. Under the optimal conditions, 17.47 g/L of β-1,3-glucooligosaccharides was produced from 20 g/L of curdlan, representing a conversion yield of 87.4% (w/w). Using this process, β-1,3-glucooligosaccharides were conveniently produced in a one-step reaction without any chemicals or enzymes. This hydrothermal hydrolysis for curdlan exhibited the best performance among various hydrolysis processes reported to date. This method can be applied to large-scale production of β-1,3-glucooligosaccharides for the functional food and biopharmaceutical industries.
