Abstract:Superfine grinding technology can obviously increase the specific surface area and surface energy of food raw materials，and also give special physical and chemical characteristics，molecular weight distribution and functional characteristics of food raw materials due to small size effect.In recent years，domestic and foreign scholars have gradually strengthened the theoretical depth of research on food superfine grinding technology，which has also been more widely used in aquatic products，grain and oil，soft drinks，flavorings processing and other aspects.In this paper，the effect of superfine grinding technology on physical and chemical properties，structure and function of food is introduced.
