In the era of globalization,the agricultural processing and food industry is facing many problems such as population growth,resource scarcity,cultural invasion,climate change,and consumer demand changes,which have an internal impact on the traditional agricultural processing industry.The integration of agronomy and food science has become an important means to solve the above problems.Agronomy research can provide raw materials for the agricultural processing industry,and food science can improve the quality and safety of food production,so as to achieve diversified development.In this context,this paper carries out research,summarizes the core problems that need to be solved in agricultural product processing and food innovation,and then puts forward the effective path of agricultural product processing and food innovation under the background of the integration of agronomy and food science.
