Preparation method of acer truncatum pterodium living bacteria enzymes stock solution

The invention discloses a preparation method of an acer truncatum pterodium living bacteria enzymes stock solution. The preparation method comprises the following steps: cleaning acer truncatum pterodium, draining off, mixing the acer truncatum pterodium with honey and pure water to obtain acer truncatum pterodium fermented stock solution for later use; culturing edible probiotics strain, namely, actic acid bacteria, to prepare fermented liquid; adding the fermented liquid into the fermented stock solution, and fermenting for 8-16d at 25-35 DEG C; and filtering the fermented liquid to obtain the acer truncatum pterodium living bacteria enzymes stock solution. According to the preparation method, a saline solution is utilized for sterilizing, the fermenting temperature is strictly controlled, and probiotics strain is inoculated, so that the loss of the nutritional ingredients of enzymes is effectively reduced, and the activity of enzymes is kept to the greatest degree; the probiotics, namely, lactic acid bacte
