Aqueous extraction of sugarcane bagasse hemicellulose and production of xylose syrup
Abstract
At the optimum level of severity, the aqueous extraction of sugarcane bagasse, an abundant agricultural residue, gave, depending on the degree of comminution, 60% to 89% yield of xylose, most of it in the form of a water soluble xylan. A process for producing xylose-rich syrups was conceived and tested, consisting of aqueous extraction, acid hydrolysis of the concentrated aqueous extract, centrifugal clarification of the hydrolysate, and recovery of the acid by continuous ion exclusion. The cost estimate indicates operating costs on the order of $0.12 to $0.15/kg xylose, in the form of xylose-rich molasses.
