A method for preparing beads containing at least one active ingredient, such as a flavor, fragrance, vitamin, and/or coloring material, to food or tobacco products, where the active ingredient is released at a controlled rate. Discrete droplets of the active ingredient and an acid polysaccharide are formed in an aqueous medium, then the droplets are converted to water insoluble gel beads by introducing the droplets into a solution containing multivalent cations, thereby building a suspension of gel beads. The beads may then be added to the food or tobacco product in an effective amount to flavor, perfume, vitamize, and/or color the product. The beads are heat and mechanically stable.

[ What is claimed is:] [1.]1. A process for preparing beads as food or tobacco additives containing at least one active ingredient which is released at a controlled rate, said process comprising the steps of:first forming discrete droplets of said active ingredient in the form of first droplets or particles and an acid polysaccharide in an aqueous medium, andconverting said discrete droplets to water-insoluble gel beads by thereafter introducing said discrete droplets into a solution containing multivalent cations thereby building a suspension of gel beads, said beads having a homogeneous composition and texture from inside to outside in which the active ingredient in the form of first droplets or particles is uniformly distributed.
