The invention discloses a preparation method for a low-lactose fermented dairy product. The preparation method has two modes; in one of the modes, lactase is added into milk and ferment is inoculated at the same time, so that the low-lactose fermented dairy product is prepared; in the other mode, lactase is first added into fresh milk, so that lactose is hydrolyzed into glucose and galactose, and ferment is then inoculated, so that the fermented dairy product is prepared. The low-lactose fermented dairy product prepared by the preparation method not only has the characteristics of low lactose content and high viable count, but also has the specific flavor and taste of fermented milk, the change of acidity is little in the process of later storage, and the taste is good. The preparation method is applicable to the preparation of low-lactose fermented dairy products.
