Probiotic microcapsules and preparation method thereof

Abstract

The invention discloses probiotic microcapsules. The probiotic microcapsules are prepared by taking whey protein as a microcapsule coating material and probiotic as a capsule core, mixing the whey protein and the probiotic and drying the mixture by using spray. The whey protein is mixed with the probiotic by means of the gel forming property of the whey protein, and the mixture is dried by using the spray to form the microcapsules; and therefore the aim of storing the probiotic for a long time is fulfilled and the harm on a thallus caused by high temperature and drying is prevented. Compared with a conventional freeze drying method, the preparation method reduces production cost and is suitable for industrial production.
