• Buckwheat consumption is associated with positive health effects in humans. Buckwheat has diverse nutrients with biological functions. Buckwheat storage protein is gluten free and is a major bio-factor responsible for the functions. The protein can be a source of allergens. It is important to understand the biological properties and food uses of buckwheat protein to develop buckwheat as a “healthy” grain. This review summarizes diverse biological activities of proteins and peptides from both common and Tartary buckwheat seeds. Strategies to reduce the symptoms of buckwheat protein allergy are discussed. The properties of the proteins and peptides in relation to the quality of buckwheat based products are also reviewed. Research gaps in better understanding and using buckwheat proteins and peptides for food applications are identified. The protein isolates from buckwheat have been hydrolyzed into a range of peptides. These peptides showed diverse biological activities in vitro and in vivo. They include trypsin inhibition, antiaging, modulating gut microbiota, prevention of cardiovascular diseases, blood pressure lowering, immunomodulatory, antidiabetic, antimicrobial, anticancer and antioxidant capacities. Buckwheat has been processed into a range of products such as vinegar, beverages and breads. The quality of these products can be significantly affected by the protein and peptide properties. Overall, buckwheat proteins and peptides have potential to be developed into functional food products. •Buckwheat protein is gluten free but is also a source of allergens.•Buckwheat peptides are antimicrobial, antihypertensive, antidiabetic and antiaging.•There are diverse strategies to reduce the allergenicity of buckwheat proteins.•Buckwheat peptides and proteins showed similar bio-functions to other peptides.•Buckwheat proteins and peptides have many potential food applications.
