The invention relates to a method for producing a liquid milk product containing fruit-vegetable granules, wherein the compositions of raw materials of the liquid milk product comprises milk, fruit-vegetable granule material liquid, a stabilizer and water. The production method comprises the following: 1) a step of preparing a base material, which is to mix the milk, the stabilizer and the water well, homogenize the mixture and obtain the base material; 2) a step of adding the fruit-vegetable granules, which is to convey the fruit-vegetable granule material liquid to a production pipeline, mix the fruit-vegetable granule material liquid with the base material on line, obtain mixed material liquid and convey the mixed material liquid to a sterilization machine for sterilization; and 3) a step of canning the material liquid, which is to can the sterilized mixed material liquid and obtain the liquid milk product. The production method does not need to temporarily store or delay storing the material liquid and does not need agitation, thereby reducing the destruction of the fruit-vegetable granules which is caused by mechanical agitation, protecting the shape and size of the fruit-vegetable granules from destruction and reducing the broken rate of the fruit-vegetable granules. In addition, as the liquid milk product is uniform in the content of the fruit-vegetable granules in every unit package and good in taste, the method improves product quality.
