Abstract
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.
