This invention relates to the field of herbal material processing technology, and discloses a fermentation and processing technique and preparation method for medicinal and edible herbs. The invention comprises four core processes: traditional processing, pretreatment, two-stage fermentation, and extraction and purification. The processing step uses stir-frying and steaming to activate the effective components of the medicinal materials and eliminate toxicity. The pretreatment step involves pulverizing the raw materials to 20-40 mesh, sterilizing them at 115℃ for 20 minutes, and then cooling them for later use. The fermentation step involves inoculating food-grade compound microorganisms for a primary fermentation of 7 days; when the glycosidase activity is not less than 120 U / mL, a secondary synergistic fermentation is initiated for 3 days. On the 10th day of the final fermentation, the temperature is raised to 85-90℃ and held for 30 minutes to terminate the fermentation. The extraction and purification step involves ethanol reflux extraction, double filtration, defatting, macroporous resin elution, and spray drying to finally obtain a powdered product with a total active ingredient content of 90%. This invention effectively improves the conversion rate of rare active ingredients and the purity of the product, maximizing the utilization of the value of medicinal and edible materials.
