A method of encapsulating a volatile, water-soluble substance in capsules having a hydrogel shell and an oily interior includes (i) providing blank capsules having a hydrogel shell and an oily interior and (ii) immersing the capsules in an aqueous solution of the volatile, water-soluble substance for a time sufficient for them to load to a desired extent with the volatile, water-soluble substance. The aqueous solution additionally has dissolved therein to saturation point at least one water-soluble, non-volatile material. The method permits the easy and durable encapsulation of volatile materials that hitherto have been difficult to encapsulate.

Encapsulation method for compounds

Heterogenous matrix particles having a continuous phase of a polymer and a discontinuous phase of an oil, and optionally an active such as a flavor or a fragrance. The continuous phase comprises at least one filler. The matrix particles exhibit high loading efficiency and low amounts of surface oil.
