An improved process is disclosed for producing corn fiber having a high total dietary fiber content and a reduced SO.sub.2 content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-milling process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content. This fiber fraction is then passed into a first centrifugal paddle screen followed by two stages of washing, including washing with a second centrifugal paddle screen. Fiber from the second centrifugal paddle screen, which is optionally pressed to remove water that contains dissolved SO.sub.2, is dried to make the final product. Heated water can be used during washing to remove additional SO.sub.2 more effectively.

Process for producing a high total dietary corn fiber

A process for producing corn fiber having a high total dietary fiber content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-millng process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content. This fiber fraction may then be passed into a centrifual paddle screen to give a product of even higher total dietary fiber content.

A process for separating saccharides by exclusion chromatography wherein a feed mixture of saccharides is supplied to a molecular exclusion chromatography zone from which at least three fractions are removed. The first fraction contains the least diffusible saccharides of the mixture which generally are the highest molecular weight components, the second fraction contains predominantly intermediate molecular weight saccharides and the third fraction contains predominantly lower molecular weight saccharide fractions. After supplying the feed to the column, the zone is continuously eluted, first with the first fraction removed from the column followed by elution with water. The use of the first fraction from the column as an eluting solvent serves to minimize the amount of water employed as an eluting solvent.
