Abstract:
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, comprising the steps of(a) hydrolysis of the sugar beet pulp to obtain a sugar beet pulp hydrolysate, (b) solids separation from the sugar beet pulp hydrolysate to obtain an aqueous solution of the sugar beet pulp hydrolysate, (c) fractionation and desalting of the aqueous solution of the sugar beet pulp hydrolysate using a separation process based on molecular weight to obtain a desalted solution enriched in pectin and a desalted solution enriched in pectic sugars/oligomers, (d) recovering the desalted solution enriched in pectin, and (e) recovering the desalted solution enriched in pectic sugars/oligomers.
