Abstract

The invention discloses probiotics powder and a production method thereof. The probiotics powder is prepared from, by mass, 17-55 parts of probiotics freeze-dried powder, 2-15 parts of zinc gluconateand 3-23 parts of water-soluble dietary fibers; wherein the probiotic freeze-dried powder comprises probiotics, silicon dioxide aerogel and a freeze-drying protective agent. According to the preparation method, the silicon dioxide hydrogel is used as a base material of a probiotic culture medium, the probiotics can be uniformly distributed and grow in a porous structure of the hydrogel, the product uniformity is high, a three-dimensional network structure of the silicon dioxide hydrogel can play a role in protecting probiotics thalli in the freeze drying process, and the survival rate of the probiotics is increased.

Description

technical field [0001] The invention relates to a health product and a production method thereof, in particular to a probiotic and a production method thereof. Background technique [0002] Probiotics belong to a class of microorganisms parasitic in the human body. They carry out life activities by absorbing nutrients in the human body. During this process, they can produce substances beneficial to the human body. At the same time, the reproduction of probiotics can inhibit the growth of harmful bacteria and further promote human health. . For example, lactic acid bacteria can ferment carbohydrates to produce lactic acid, improve food digestion, and be more conducive to gastrointestinal absorption; bifidobacteria are widely present in the human oral cavity and gastrointestinal tract, and the vitamins, acetic acid, and lactic acid produced by bifidobacteria during metabolism Such organic acids can not only accelerate the body's absorption of minerals, but also promote intest...
