Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aqueous solution of sodium methionate having a low content of sodium carbonate. SOLUTION: After further addition of sodium hydroxide, water is distilled off from a crude hydrolyzate mixture until the content of sodium methionate attains 60-90 wt.% and the precipitated sodium carbonate is separated and removed as an anhydrous monohydrate and/or an anhydrous bicarbonate at 90-140 deg.C temperature.

Abstract: 2. Animal feed additives based on fermentation broth further contain, in addition to the additive, other fermentation broth constituents. Such products, after spray-drying, generally have an excessively low bulk density and/or are sticky. To granulate these products, processing aids have therefore been added, e.g. perlite or sawdust. Alternatively, such products have been dewatered by azeotropic distillation with paraffin oil to give granules. The object of the invention is a highly concentrated animal feed additive which, in particular, is to have a bulk density of at least 550 kg/m and a standardisable active compound content. 2.2. By pelletising, stable granules can be produced from an animal feed additive-containing fermentation broth if the fermentation product is contained at at least 33% by weight. Granules can particularly readily be produced by pelletising if the pellets are built up of at least 30% by weight fine grain with at least 70% by weight having a particle size

Abstract: 2.1. Fermentative preparation of amino acids for animal feed supplement purposes is a complex process, since the amino acid is present in the fermentation broth at only a few percent. Drying the crude fermentation broth and using it as such generally led to aggregating sticky products or to products having too low a supplementary amino acid content. Using the new animal feed supplement and preparation process, a supplementary amino acid is intended to be made available which is not too expensive, not excessively hygroscopic or sticky, and whose contents can be standardised. 2.2. The animal feed supplement is based on a fermentation broth and contains the majority of its components, if required, with the exception of part of the biomass. Preferably, the biomass is present at no more than 10 % by weight of the dry matter. Proteins are preferably present at up to a maximum of 10 % by weight. For the production, during fermentation, at least towards the end, the sugar content is adjusted to a value of at most 4 g/l and during further processing, if required, at least a part of the biomass is separated off. 2.3. Supplementation or preparation of animal feed agents or premixes, in particular containing lysine.
