Advance on anti-diabetic effects of protein hydrolysates and peptides derived from cereals and pseudocereals

Abstract

Diabetes is a complex and heterogeneous disorder disease with elevated blood glucose, which is one of the most serious global public health problems. Cereals and pseudocereals, as staple food, are major sources of dietary protein. Cereal and pseudocereal proteins are potential sources of food-derived bioactive peptides and proposed to prevent and ameliorate diabetes. According to recent researches, this review summaries the isolation, purification and analysis of anti-diabetic protein hydrolysates and peptides from cereals and pseudocereals. In addition, their anti-diabetic activities and mechanisms were reviewed by in vitro inhibition of carbohydrate digestive enzyme and dipeptidyl peptidase-IV, in vivo hypoglycaemic effects, and glucose homeostasis in cell model.
