Abstract
The embodiment of the present disclosure provides a system for co-producing a xylitol and a caramel pigment by utilizing a xylose mother liquid, including an extraction assembly, a refined hydrogenation assembly and a browning reaction assembly. The extraction assembly is configured to obtain an extracted liquid and a raffinate liquid respectively by performing an initial extraction on the xylose mother liquid; the refined hydrogenation assembly is configured to prepare a crystal xylitol by performing a refined hydrogenation process on the extracted liquid; the browning reaction assembly is configured to prepare the caramel pigment by performing a browning reaction process on the raffinate liquid.
