Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a method of preparing crystalline L-arabinose by extraction of sugar beet pulp, from which sugar has been extracted, in a strong alkaline solution, by hydrolysis of the obtained crude araban with a strong acid at an elevated temperature, by neutralization and filtration of the obtained solution, by chromatographic separation of the L-arabinose fraction, by purification of the obtained L-arabinose solution by means of cation and anion exchangers and adsorbent resins, and by recovering the pure L-arabinose as a crystalline product.

Abstract: The invention relates to a raw material for use in the preparation of pectin and related compounds, the raw material being pressed, stabilized sugar beet pulp subjected to biotechnical pre-treatment. In accordance with the invention the raw material is prepared by pre-treating fresh pressed sugar beet pulp by lowering the pH to a value between 3.5 and 4.5 (preferably 3.9 and 4.3) and subsequently storing the obtained acid pulp in tight, i.e. substantially oxygen-free conditions.

Abstract: The method relates to minimizing power consumption in a computing device, which executes the requested tasks in a high power mode, in which it has normal processing power and, correspondingly, normal power consumption, and which, after it has executed the requested tasks, is switched to a low power mode, in which it has limited processing power and, correspondingly, a considerably lower power consumption. In the method of the invention, the power consumption of a computing device is decreased by lengthening the time during which the device remains in the low power mode in such a way that the device is not switched to a high power mode immediately when the user starts the input, but the switching is delayed.
