The invention relates to the technical field of dairy product processing, particularly to a detection method for thermal stability of protein in dairy products. The detection method includes the following steps: mixing a dairy product with water to obtain a first sample solution; treating the first sample solution for 10 min to 40 min at the temperature of 100 DEG C to 135 DEG C, so as to obtain a second sample solution; detecting the second sample solution to obtain the thermal stability of protein in the second sample solution. Through the adoption of the detection method provided by the invention, the thermal stability of the protein in the dairy products can be quickly and accurately detected, so that dairy products with poor protein thermal stability can be removed, and dairy products with excellent protein thermal stability can be adopted for the production of finished products, continuous production longer than 6 h of ultra-high temperature sterilizing equipment is guaranteed, as a result, the productivity of a production line is improved, the AIC frequency is lowered, the production cost is controlled, and benefits of enterprises are increased. |
