After egg white moderately hydrolyzed,a mixture of peptide was generated.The absorptivity of egg got raised by controlling the degree of hydrolysis.And the mixture of peptide was more likely for our body to absorb.Moreover,this peptide also got some specific physiological functions.In this paper,the activity of lower blood pressure,free radical scavenging activity and improving immunity features of egg white peptide were reviewed.And about how to choose enzyme of egg white peptide,how to determinate the degree of hydrolysis (DH) and some other key processes were also intr...
