Abstract: A process for obtaining white sugar from e.g. sugar cane by treating the crude sugar juice with acid activated bentonite preferably selected from the group of smectites, whereby the acid activated bentonite mixture replaces the traditional environmental unfriendly sulfitation process. The acid-activated clay together with polyaluminium salts, and preferably phosphoric and/or sulfuric acid allows obtaining a high quality white sugar.
