Patent ID: 8603538

Claim:
A process for the production of an n-butyric acid compound in microencapsulated form, comprising the stages of: providing a granular material based on the n-butyric acid compound, mixing the granular material with a matrix having a content of long-chain C14-C22 saturated fatty acids of from 40% to 95%, heating the mixture to a temperature higher than the melting temperature of the lipid component of the matrix, and spraying the mixture into a cooling chamber having a temperature lower than the melting temperature of the lipid component of the matrix, so that the latter solidifies around the granular material, forming a covering for the said granular material, wherein the matrix comprises a mineral agent in an amount of from 1% to 20% relative to the matrix, the mineral agent having a fraction of calcium sulphate dihydrate higher than 50%.
