Beads as food additive consisting of a matrix of a reticulated multivalent cation containing acid polysaccharide and at least one water soluble and/or voltaile liquid or solid active ingredient filling at least partly the voids built by the acid polysaccharide are prepared by a process comprising the steps of forming a system consisting of a dispersion or emulsion of a water immiscible material in an aqueous solution of an acid polysaccharide, especially in the form of an alkali metal salt, an emulsifier and, optionally, one or more other water soluble or water dispersible substances; forming of discrete droplets of said system; converting said droplets to water-insoluble gel beads by introducing said droplets in an aqueous or alcoholic solution containing multivalent cations, thereby building a suspension of gel beads; isolating said gel beads from said suspension; optionally, drying the isolated beads, and loading the isolated beads with at least one active ingredient. The active ingredient is at least one compound of the group consisting of flavors, fragrances, vitamins or coloring materials.

On prépare des granulés en tant qu'additif destiné aux aliments et se composant d'une matrice d'un cation polyvalent réticulé contenant un polysaccharide d'acide ainsi qu'au moins un principe actif, liquide ou solide, hydrosoluble et/ou volatil, et remplissant au moins partiellement les vides instaurés par le polysaccharide d'acide, selon un procédé comprenant les étapes consistant à former un système, lequel comporte une dispersion ou émulsion d'un matériau non miscible à l'eau, placée dans une solution aqueuse d'un polysaccharide d'acide, notamment sous la forme d'un sel de métal alcalin, un émulsifiant et, le cas échéant, au moins une substance dispersable dans l'eau ou hydrosoluble, à former des gouttelettes distinctes de ce système, à convertir ces gouttelettes en granulés gélifiés insolubles dans l'eau, en introduisant ces gouttelettes dans une solution aqueuse ou alcoolique contenant des cations polyvalents, afin d'obtenir ainsi une suspension de granulés gélifiés, à isoler de ladite suspension ces granulés gélifiés, éventuellement à les sécher et à charger ces granulés isolés avec au moins un principe actif. Le principe actif comprend au moins un composé du groupe constitué par des saveurs, des arômes, des vitamines ou des colorants.
