Abstract

The invention provides tea yoghurt and a preparation method thereof. The preparation method comprises the following steps: homogenizing raw milk, taking homogenized raw milk which accounts for 20-30 percent of the total mass of the homogenized raw milk, preheating, adding a sweetening agent, tea leaves and an antioxidant, preserving heat, leaching, filtering, mixing the filtrate and the residual homogenized raw milk, sterilizing, cooling, and inoculating a fermentation agent for fermenting, thereby obtaining the product. The tea yoghurt prepared by the preparation method refers to real sense of tea yoghurt, is strong in tea aroma and is not added with any tea flavor or tea concentrate, and the tea flavor completely comes from the tea leaves. Meanwhile, due to the addition of antioxidant substances, the stability of the tea flavor in the guarantee period is guaranteed. According to the preparation method disclosed by the invention, due to process adjustment, blockage of a homogenizer in the product preparation process is avoided.
