ABSTRACT:
The present invention provides a method for producing preparations comprising soluble arabinoxylans as co-products of ethanol production through fermentation of whole-grain cereals. The method results in preparations that are highly enriched in soluble arabinoxylans, which can be used as a food, beverage, or feed ingredients.
