Process for the production of a composition, the composition and the use thereof as food additive

InactiveUS20120035127A1Degree of polymerization superiorBiocideOrganic active ingredientsFood additiveDietary fiber
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.

Preparation of microbial oligosaccharide with prebiotic function

The invention provides a method for preparing microbial oligosaccharide with probiotic action. The method is characterized in that: a sugar producing culture medium is used for liquid fermentation of K.rhinoscleromatis K13 to extract extracellular polysaccharide; enzymatic solution of phage glycanase is prepared, the enzymatic solution and water solution of extracellular polysaccharide are mixed for enzymolysis, the undegraded macro molecular sugar is removed by ultrafiltration, and the obtained filtrate is refined and condensed to obtain the microbial oligosaccharide KOS. Tests show that the microbial oligosaccharide KOS is non-digestible oligosaccharide which can promote the growth of probiotics such as bifidobacterium, lactobacillus and the like, inhibit the growth of harmful bacteria such as pathogenic bacteria, putrefying bacteria and the like, and has the functions of improving the micro ecological environment of the intestinal tract and cleaning the intestinal tract. The microbial oligosaccharide KOS is novel probiotics, which is novel microbial oligosaccharide which is obtained by degrading the extracellular polysaccharide of the K.rhinoscleromatis K13 through the phage glycanase, and the raw materials used in the method are different from those of other polysaccharides, and the result repeatability is good due to the degradation by an enzyme method, so that the application prospect is wide.
