The invention belongs to the technical field of biology and particularly relates to a symbiotic bifidobacterium composite microcapsule and a preparation method thereof. According to the composite microcapsule disclosed by the invention, bifidobacterium longum biovar infantis, bifidobacterium animalis subsp. lactis, fructo-oligosaccharide and inulin are taken as core materials, so that intestinal flora can be enriched, bacterial strain proliferation can be promoted, and intestinal microecological health is further promoted; and pectin and sodium alginate serves as wall materials, are free of toxic or side effects and have relatively high gelling property, so that the embedding effect is improved. According to the composite microcapsule prepared by the method, the survival rate of strains can be increased, and the embedded probiotics can be stably colonized in gastrointestinal tracts to better play a physiological role; the particle size of the prepared microcapsule is 2.0mm-2.5mm, the embedding rate is greater
