Antimicrobial peptides purified from hydrolysates of kanihua (Chenopodium pallidicaule Aellen) seed protein fractions.

The kanihua (Chenopodium pallidicaule Aellen) Andean grain from the Peruvian Altiplano presents proteins of 15% to 19%. The objective was to obtain purified bioactive antimicrobial peptides (AMPs), hydrolyzed with Alcalase and Pepsin-pancreatin sequential system of protein fractions of kanihua varieties Ramis (KR) and Cupi-Sayhua (KS), and hydrolysates with different degrees of hydrolysis (DH) and percentage inhibition (IP) of the growth of E. coli, S.
