The present disclosure relates to a method for preparing liquid maltitol and liquid polyols from a raffinate including maltitol. The method comprises the following steps: obtaining a hydrogenated liquid by hydrogenating a pre-treated raffinate including maltitol, obtaining a post-treated liquid by post-treatment of the hydrogenated liquid to remove impurities, obtaining a dilute liquid and a concentrated maltitol solution by membrane-separation of the post-treated liquid, and using the dilute liquid as the liquid polyols, and obtaining the liquid maltitol by mixing the concentrated maltitol solution with a prepared maltitol solution with a maltitol content of over 50%, wherein the liquid maltitol has a maltitol content greater than or equal to 50% and meets a standard. Before the membrane separation process, the present disclosure reduces the reducing sugar content in the liquid by hydrogenation to lower the risk of yellowing during the process and to improve the quality of the final product.

The embodiments of the present disclosure provides a method of co-producing erythritol and arabinose by using a xylose mother liquor, wherein an extract and a raffinate are obtained by separating the xylose mother liquor through a first chromatography, the extract is configured to prepare crystallized xylose, the raffinate and the liquid glucose or crystallized glucose are blended and erythritol is produced by using awith high osmotolerant and a high conversion rate. erythritol crystals are obtained by centrifugation and crystallization first by using characteristics of low solubility degree and easy crystallization of the erythritol, the arabinose raffinate having a high content of arabinose is obtained by separating a centrifuged erythritol mother liquor through a second chromatography, and arabinose crystals are obtained based on the arabinose raffinate.
