Method for preparing lactobacillus microcapsules

The invention discloses a method for preparing lactobacillus microcapsules, which relates to a method for preparing microcapsules. The method solves the defects that the prior method for preparing thelactobacillus microcapsules cannot obtain dry lactobacillus microcapsule powder easily, the lactobacilli are diffused unevenly, the mortality rate of the lactobacilli is high in the preparation process, a used crosslinking agent has certain toxicity, and the yield of the lactobacillus microcapsules is low. The method for preparing the lactobacillus microcapsules comprises the following steps: firstly, mixing a core material and a wall material; secondly, preparing a primary emulsion; thirdly, preparing a microcapsule oil solution; fourthly, preparing a multiple emulsion; and fifthly, performing condensation, solidification and vacuum freeze drying. The method for preparing the lactobacillus microcapsules can obtain the dry lactobacillus microcapsule powder and avoid the defects of the uneven diffusion of the lactobacilli and the high mortality rate by means of the vacuum freeze drying; the method uses no crosslinking agents and has no toxic action on the lactobacilli; the external water phase is not miscible with the internal water phase; and the yield of the lactobacillus microcapsules prepared by the method reaches 84.6 percent, and the freeze-drying survival rate reaches over 60.107 percent.
