The application discloses a preparation method of oat plant-based fermented milk rich in polyphenols based on a combined enzymolysis-fermentation technology. The preparation method comprises the following steps: after oat is soaked and cleaned, the oat is dried to obtain pretreated oat; the pretreated oat is baked and crushed, and then ball milled to obtain oat ultrafine powder; then, water is added to the oat ultrafine powder to obtain oat milk, the oat milk is stirred and subjected to high-speed shearing, the oat milk is completely dissolved and then gelatinized, and then enzyme is added to perform enzymolysis to obtain an enzymolysis solution; after the enzyme is inactivated, the enzymolysis solution is mixed and homogenized to obtain a homogenized solution, the homogenized solution is sterilized and cooled to obtain a uniform and stable system; finally, a strain is inoculated into the uniform and stable system to perform fermentation and post-ripening to obtain oat plant-based fermented milk. According to the preparation method, a nitrogen source does not need to be additionally added, the polyphenol content of the system and the acidity of the product can be effectively improved, and the fermentation time is shortened.
