Calcium butyrate microcapsule as well as preparation method and application thereof

The invention provides a calcium butyrate microcapsule as well as a preparation method and application thereof, and relates to the technical field of microcapsules. According to the method, bacteria in a sodium butyrate fermentation process are used as a capsule material, after clostridium butyricum fermentation is finished, the bacteria are subjected to wall breaking, butyric acid is adsorbed into cells again, and volatilization of butyrate odor is avoided through re-embedding of the bacteria on the butyric acid. The preparation process of the calcium butyrate microcapsule is simple, no extrachemical reagent is added, basically no toxic and harmful chemical reagent needs to be introduced, and the risk of solvent residues is avoided; the bacteria are used as a capsule material, so that the taste masking effect is better, and the slow release of a medicine can be realized to a certain extent; and bacterial protein, saccharides, vitamins, nutritional factors and the like in the bacteriacan be used as nutritiona
