摘要：
An active-containing microparticle adapted to release the active in a desired end-use, comprising(a) an active-containing core active-containing core, optionally formed on an inner core, comprising a continuous hydrophilic medium in which at least one active is dissolved or is present as? dispersed particles；(b) an active-free barrier layer, surrounding completely the core； and(c) surrounding the barrier layer, a layer of polymeric material having a solubility in water at 25° C. of 0.1% by weight maximum；the barrier layer comprising a material selected from waxes, fats and materials suitable for use as the continuous hydrophilic medium of the core, and which is solid in the conditions of the desired end-use. The particles are useful, for example, for the delayed release of flavors in foods and beverages.
