The present invention relates to a process for the production of a functional food additive, such as a prebiotic composition, comprising the steps of. (a) providing a plant based material wherein the plant is selected from the group consisting of cereals, legumes, tubers and mixtures thereof, wherein said plant based material comprises dietary fiber optionally starchy material and optionally glucose, or wherein said plant based material comprises starchy material, and optionally glucose; (b): (b1) hydrolyzing or tranglucosylating at least part of the dietary fiber into glucose and into at least one non-digestible oligosaccharide and optionally into at least one non-digestible polysaccharide, and optionally hydrolyzing and transglucosylating at least part of the starchy material to glucose and into at least one non-digestible oligosaccharide, or, (b2) hydrolyzing and transglucosylating at least part of the starchy material to glucose and into at least one non-digestible oligosaccharide, and optionally hydrolyzing at least part of the maltooligosaccharides produced in step (b2) into glucose; (c) oxidizing at least part of the total glucose, consisting of at least part of said gluconic acid and/or a salt thereof obtained in step (c); thereby obtaining a composition comprising dietary fiber and gluconic acid or a salt thereof, wherein said dietary fiber comprises at least one non-digestible oligosaccharide and optionally at least one non-digestible polysaccharide as defined in claim 1. This invention also relates to a functional food additive composition and the use thereof. |
