[Objective]In this paper,to study the evaluation method of raw milk protein stability and the evaluation model of stability system. [Method]Through the alcohol test, boiling test, thermal shock test, stability test, phosphate test of the principle, testing methods, results, the advantages and disadvantages of the study and analysis, to establish a comprehensive evaluation program of raw milk protein stability, and alcohol, boiling, thermal shock, stability, phosphate test and other indicators. The evaluation model of protein stability was established by using digital tools. Through the model analysis to determine the use of raw milk grade, improve the accurate use of high-quality raw milk raw materials. [Result]The model is effective and accurate in evaluating raw milk quality. [Conclusion]Through the data sharing of quality evaluation, guide the pasture to improve the quality of raw milk, as well as the grading of dairy processing plants, accurate use for processing different types of products.
