The invention discloses a sand pear enzyme production method which comprises the following steps: A, pretreating: picking, cleaning, juicing and sterilizing; B, fermenting: putting sterilized sand pear juice into a fermentation tank, adding a carbon source and inoculation culture, controlling a fermenting temperature as 25 to 40 DEG C, controlling fermenting time as 120 to 240h, stirring once everyday and keeping moderate ventilation to prevent tank expansion; C, boiling: after temperature control fermentation, cooling to normal temperature, filtering, putting fermentation liquor into a boiling tank and boiling 1 to 2 months under normal temperature; D, deploying: deploying the boiled sand pear enzyme to produce edible terminal food of enzyme drink, enzyme oral solution, enzyme freeze-dried powder, enzyme particles and the like. The sand pear enzyme production method disclosed by the invention has a simple and high-efficiency technological process, the whole fermenting process followsancient-law fermentation, varieties of nutritional ingredients and effects of sand pear are effectively kept, sand pear taste is improved, a health-care effect is improved, sand pear additional valueis effectively improved, and economical benefits and a market popularization prospect are very high.
