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 a Yarrowia lipolytica with 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.
