The invention relates to a process of recovering galactose from a solution derived from plant-based biomass. In the process of the invention, the starting solution is subjected to one or more chromatographic fractionation steps, which may carried out with a strongly basic anion exchange resin and optionally with a strongly acid cation exchange resin, in any desired sequence, followed by recovering at least one fraction enriched in galactose. The galactose fraction thus obtained is further purified by crystallization to obtain crystalline galactose. The invention also relates to non-animal derived crystalline D-galactose.

Separation method

The invention relates to an equipment for fractionating a solution by a sequential SMB process, which equipment comprises a feed column and one or several other columns, which include a chromatographic separation resin bed. The equipment of the invention is characterized in that the feed column consists of or comprises a compartment where the resin bed is shallower than that of one or more of the other columns of the equipment. The invention also relates to a method for fractionating a solution into two or more fractions with the equipment of the invention.

Chromatographic separation

The invention relates to the recovery of deoxy sugars, such as fucose from biomass-derived solutions, such as spent liquors obtained from pulping processes. The invention is based on the use of chromatographic fractionation with specific column packing materials and combinations thereof. The deoxy sugar product obtained from the chromatographic fractionation may be further purified by crystallization. The invention also provides a novel crystalline fucose product and a novel process for the crystallization of fucose.

Separation of sugars

The present invention is directed to a method comprising a multistep process for recovering one or more monosaccharides from a solution containing at least two monosaccharides selected from the group consisting of rhamnose, arabinose, xylose and mixtures thereof by using chromatographic separation comprising at least one step, where a weak acid cation exchange resin is used for the chromatographic separation.

Method for recovering products

The invention relates to the use of a weakly acid cation exchange resin for chromatographic separation of carbohydrates. In the invention the hydrophilic/hydrophobic interaction of carbohydrates, sugars and sugar alcohols with the weakly acid cation exchange resin is utilized. The weakly acid cation exchange resin is used for separation of hydrophobic saccharides, such as deoxy, methyl and anhydrosugars and anhydrosugaralcohols from more hydrophilic saccharides.

Use of a weakly acid cation exchange resin for chromatographic separation of carbohydrates

The invention relates to a chromatographic separation process of recovering mannose with high purity. The invention is based on the use of a chromatographic separation resin including a resin which is at least partly in a Ba form resin and a resin which is in other than Ba form.

Method for the recovery of sugars

The invention relates to a method of simultaneous purification and separation of pectin and pectic sugars/oligomers from sugar beet pulp using a multi-step process in an aqueous solution. The method comprises hydrolysis of the sugar beet pulp, solids separation from the sugar beet pulp hydrolysate as well as fractionation and desalting of the aqueous solution of the sugar beet pulp hydrolysate thus obtained into a desalted solution enriched in pectin and a desalted solution enriched in pectic sugars/oligomers. The process may also comprise optional further steps, such as clarification, adsorption, concentration and further chromatographic treatment.

Process for the fractionation of sugar beet pulp

The invention relates to chromatographic fractionation of pectin-containing vegetable material, such as sugar beet pulp. In the method of the invention, a pectin-containing hydrolysate is chromatographically separated into a pectin fraction, a salt fraction and a sugar fraction. The method is carried out by using a cation exchange resin, which is preferably in the form of a multivalent metal.

Chromatographic fractionation of vegetable material

A process of preparing a L-ribose fraction having greater than 97% purity starting from an aqueous solution of L-arabinose is provided by utilizing an epimerization reaction conducted in the presence of a Mo compound and eluting the product formed by said epimerization reaction through a separation zone containing a strong acid cation exchange resin. A process of crystallized said L-ribose fraction under conditions effective to form monohydrate L-ribose crystals is also disclosed.

Process for the continuous production of high purity L-ribose
