Beads as food additive consisting of a matrix of a reticulated multivalent
cation containing acid polysaccharide and at least one water soluble and/or volatile
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.
