Abstract:
A method for encapsulating or embedding a component in a matrix comprising:a. obtaining a formable mixture by admixing ingredients comprising at least one plasticizable matrix material, a liquid plasticizer, an encapsulant, a matrix component which is substantially non-plasticizable at temperatures lower than the decomposition temperature of the encapsulant comprising an at least substantially non-gelatinized starch, and at least one component for controlling the rate of release of the encapsulant, wherein said plasticizable matrix material is plasticizable by said liquid plasticizer at a temperature which does not substantially destroy said encapsulant, said admixing being under low shear and low temperature conditions to plasticize the plasticizable material without substantially destroying the encapsulant and without substantially gelatinizing or cooking the plasticizable matrix material to obtain a substantially homogeneous, formable mixture, b. forming said formable mixture into pieces, and c. drying said pieces.
