Abstract:Teff is rich in protein and contains all the essential amino acids needed by the human body. As a natural gluten-free grain， teff has become a valuable dietary source for patients with celiac disease and other gluten allergies due to its high protein nutritional value and rich content of other nutrients. In recent years， the demand for teff has been increasing， and it has been widely planted in many countries. Based on this， this review analyzed the composition of teff protein and its amino acids， as well as the extraction methods of teff protein. It also explored the functional properties of teff affected by protein and the application research of teff based on protein， so as to provide reference for the future development of teff food， functional improvement of teff protein， and further expansion of the application scope of teff protein.
