    摘要： Related to are a device and a method for performing continuous carbonation and impurity removal for xylose mother liquor. The device includes an alkali addition unit, a continuous carbonating unit, a discharge controlling unit, a CO 2 supply station, a vapor station and an after-carbonation tank, wherein the alkali addition unit is configured to add Ca(OH) 2 alkaline liquid into xylose mother liquor, the continuous carbonating unit is configured to introduce CO 2 supplied from the CO 2 supply station into the alkali-added xylose mother liquor to perform carbonation and mixing so as to remove impurities such as colloid and pigment in xylose mother liquor, the discharge controlling unit is configured to introduce CO 2 supplied from the CO 2 supply station and vapor transported from the vapor station into the carbonated xylose mother liquor so as to control and stabilize a pH value of the carbonated xylose mother liquor, and the after-carbonation tank is configured to collect and temporarily store the carbonated and impurity-removed xylose mother liquor so as to prepare for a next procedure. Further, a method using the device is disclosed. According to the device and the method, the pH of xylose mother liquor is continuously regulated and stabilized and continuous feeding and discharge are performed with highly automated device so as to achieve continuous and uninterrupted production, and thus facilitate improving the production efficiency.

    摘要： [Objective] To provide a mannose extraction method with which high-purity mannose can be extremely easily extracted by performing a two-stage hydrolysis treatment on a plant-based raw material. [Solving Means] Mannose is extracted from a plant-based raw material by carrying out a first hydrolysis step S1 in which a plant-based raw material M1 and a first acid catalyst A1 are mixed and heated, a separation step S2 in which a reaction product M2 obtained by the first hydrolysis step is separated and recovered, and a second hydrolysis step S3 in which the reaction product obtained by the separation step and a second acid catalyst A2 are mixed and heated.
