The invention provides fermented milk and a preparation method thereof, and the fermented milk is prepared from the following raw materials: an
emulsion, a stabilizer, an emulsifier, a
leavening agent and a salt substance; wherein the stabilizer comprises
gelatin. The preparation method of the fermented milk comprises the following steps: adding a stabilizer, an emulsifier and a salt substance into a heated
emulsion to circularly melt the materials, so as to obtain a prepared
emulsion; sequentially carrying out homogenization treatment and sterilization treatment on the prepared emulsion; adding a
leavening agent into the prepared emulsion subjected to sterilization treatment, and performing
fermentation treatment; and sequentially carrying out hot filling and rapid cooling treatment on the prepared emulsion subjected to
fermentation treatment. The raw materials of the fermented milk comprise the stabilizer, the emulsifier and the salt substance, and the stabilizer comprises the
gelatin, so that the situations of whey
precipitation and water-milk separation in the storage and transportation process of the fermented milk can be avoided, and the
consumer experience is improved.
