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.
L'invention concerne une technique de purification et de séparation simultanées de pectine et de sucres/oligomères pectiques à partir de pulpe de betterave sucrière dans une solution aqueuse au moyen d'un processus à plusieurs étapes. Ce processus comprend une hydrolyse de pulpe de betterave sucrière, une séparation des solides de l'hydrolysat de pulpe de betterave sucrière, ainsi qu'un fractionnement et un dessalement de la solution aqueuse de l'hydrolysat de pulpe de betterave sucrière ainsi obtenu, d'où la production d'une solution dessalée enrichie en pectine et d'une solution dessalée enrichie en sucres/oligomères pectiques. Ce processus comprend également des étapes facultatives, telles qu'une clarification, une adsorption, une concentration, voire un traitement chromatographique.
