Probiotic embedding protection method

The invention discloses a probiotic embedding protection method, and belongs to the technical field of probiotics. Xanthan gum and sodium alginate form a polyelectrolyte compound gel, and the polyelectrolyte compound gel is mixed with bacterial sludge and then coagulated on the surface of the bacterial sludge to form microcapsules to be separated out, so that the probiotics are well protected, and the acid resistance of the probiotics is improved. The combination of the whey protein and the isomaltooligosacharide can greatly improve the resistance of bacteria to a high-salt environment, so that the cholate resistance of the probiotics is improved. The embedded probiotics obtained by the method disclosed by the invention can realize targeted release, so that the preservation time of the probiotics at room temperature can be prolonged, the digestion effect of gastric juice can be avoided, the probiotics can smoothly reach intestinal organs to play a role, and the targeted release effect is realized.
