A process for the production of an n-butyric acid compound in microencapsulated form comprises 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 %, and an amount of between 1 % and 20 % of a mineral agent in which an effective amount of calcium sulphate dihydrate is present, heating the mixture to a temperature higher than the melting temperature of the lipid component of the matrix, - 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 thereof. |
