摘要： Described herein is a method for making colored hydrogel-based materials, and products relating thereto. The method includes applying an aqueous colorant composition comprising water and a colorant material to an external surface of a plurality of hydrogel-based materials. The aqueous colorant composition comprises less than 25% (v/v) of an aqueous miscible co-solvent. The hydrogel-based materials comprise a hydrogel matrix encapsulating an active ingredient composition, such as a flavor or fragrance composition. The aqueous colorant composition and the hydrogel-based materials are mixed for a sufficient duration of time to allow substantially all of the aqueous colorant composition to be absorbed into the hydrogel matrix. Optionally, the colored hydrogel-based materials may be dried to remove at least a portion of the water absorbed into the hydrogel matrix thereby leaving the colorant material therein. The resulting colored hydrogel based materials are suitable for use in foodstuffs, such as confectionaries.
