A process for the production of an n-butyric acid compound inmicroencapsulated 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 contentof long-chain C14-C22 saturated fatty acids of from 40 % to 95 %, and anamount of between 1 % and 20 % of a mineral agent inwhich an effective amount of calcium sulphate dihydrate is present, heatingthe mixture to a temperature higher than the meltingtemperature of the lipid component of the matrix, - spraying the mixture intoa cooling chamber having a temperature lower thanthe melting temperature of the lipid component of the matrix, so that thelatter solidifies around the granular material, forming acovering thereof.
