Patent ID: 11632965

Abstract:
Disclosed is a method of preparing a fermented milk. The method comprises: step 1, extruding whey protein at low temperature, mixing the extruded whey protein with inulin to prepare extruded whey protein isolate (WPI)-inulin composition; step 2, adding sucrose and the extruded WPI-inulin composition into the raw milk, and uniformly mixing and stirring the sucrose, the extruded WPI-inulin composition, and the raw milk to obtain a material A; step 3, preheating, homogenizing, sterilizing and cooling the material A to obtain a fermentation substrate; step 4, adding a fermentation agent into the fermentation substrate, filling the fermentation substrate in a container, and then performing heat-preserved fermentation, and ending the fermentation to obtain a material B; step 5, cooling the material B, and then refrigerating the material B to obtain fermented milk.
