Encapsulation of active agents as microdispersions in homogeneous natural polymeric matrices

摘要: A method for effectively encasing an active agent such as a chemical compound, seasoning, flavoring, or nutrient vitamins and minerals, including liquids, time-stable but releasable dispersion in homogeneous polymeric encapsulating matrix of modified starch, gum protein material gelatin casein to provide concentrate the agent. The is characterized that be encased mixed with under conditions rigorous intimate mechanical working applied high shearing stress without phase-separating compression compaction forces presence limited quantity water sufficient heat ensure formation viscous, semi-solid, paste constituting mobile mass plastic melt. melt, consisting distributed therethrough microdispersed phase, then formed into any desired shape, while avoiding forces, dried product stable against loss deterioration In preferred embodiment invention gradually released from enveloping at rate dependent on hydration matrix.
