[0022] The present invention also provides a preparation method of probiotic iron-zinc-calcium powder rich in various minerals, comprising the following steps:
[0023] S1: Activation of probiotics: inoculate five strains of Bifidobacterium lactis, Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium longum, and Lactobacillus plantarum on four MRS slant mediums respectively, at 30-37°C Cultivate for 10-16 hours to obtain activated slant strains;
[0024] S2, expanded culture: inoculate the obtained slant strains in the MRS liquid culture medium respectively, cultivate for 10-16h at 30-37° C. to obtain the liquid strains, and then inoculate the five liquid strains at 0.2-0.5% (v / v ) into the sterilized culture solution, cultivated at 30-37°C for 1-2 days, to obtain strain expansion solution;
[0025] S3. Fermentation: with edible glucose, milk powder, stachyose, isomalto-oligosaccharide, DHA algae oil, dietary fiber, ferrous lactate, zinc gluconate, calcium lactate,...
