Microbial ecological agent and preparation method thereof

The invention discloses a microbial ecological agent and a preparation method thereof. The microbial ecological agent mainly consists of the following raw materials based on the parts by weight: 5-50 of north caterpillar fungus reactants, 20-80 of lactic acid bacteria freeze-dried power, 5-20 of bifidus factors and 0.2-5 of vitamin; the north caterpillar fungus reactants contain 100g of north caterpillar fungus extract, 0.1-3g of alanine, 0.5-10g of glucose, 0.01-0.5g of ascorbic acid, 0-8g of sault, 0-2g of I+G and 0.001-0.01g of BHT. The microbial ecological agent is formed by preparing the north caterpillar fungus reactants, the lactic acid bacteria freeze-dried power and then mixing all the components, has multiple functions of digestion assistance, gastrointestinal disease prevention and cure, micro ecological balance maintenance and special health-care function of the north caterpillar fungus, and the like and has unique flavor and good taste. The preparation process is simple, the modern fermentation process is adopted, the north caterpillar fungus extract containing rich nutrition of amino acid, trace elements, and the like are added to fermentate and cultivate probiotics, and the number of fermentation liquid live bacteria is improved.
