Materials: fresh mushrooms, white sugar, refined salt, seasoning, etc., commercially available, lactic acid bacteria (Lb, St) species. Preparation of brewing water: 50 grams of white granulated sugar, 20 grams of salt, dissolved in 1000 ml of water, and then about 100 grams of ginger, garlic and spices are added. The water is boiled, cooled, and then placed in a pre-washed glass container. Medium, access to 50 ml lactic acid bacteria strains, incubated at 35 °C for about 20 hours, set aside. Process: fresh mushrooms → cleaning → boil for 2 minutes → pick up drain → cooling → infusion → finished product. Operation points: Pick a thick, large shiitake mushroom and remove the base material from the mushroom shank. Add a small amount of salt and spices (500 grams of fresh mushrooms and 5 grams of salt) in the boiling process, and the water must not have fresh mushrooms. In the brewing process, every 500 grams of fresh mushrooms is filled into a container filled with 1 liter of brewed water. The container of fresh mushrooms is preferably sealed. The brewing water must submerge the mushroom noodles about 3-5 cm. At the same time, in order to increase the crispness of soaking mushrooms, calcium chloride may be added in a ratio of 0.05% when the brewing water is formulated. General temperature 30 °C brew 2-3 days to mature; 20 °C brew 5-7 days to mature. In the event of mildew, a small amount of white wine, vinegar or fresh ginger or basil leaves may be added. In the production of brewing water, the ratio between the two kinds of lactic acid bacteria is determined by the taste evaluation of the finished product. According to the taste, the two types of lactic acid bacteria (Lb: St) are 1:1 mixed and have the best flavor after being mixed. The brewing temperature is preferably controlled at 20-25° C., and the brewed mushrooms with excellent flavor can be obtained after brewing for 3-4 days. .
