Soluble protein content was measured in pressurised and nonpressurised lentil protein concentrates and hydrolysates at pH 8 by DC protein assay (Biorad) using bovine serum albumin (BSA) as standard. For peptide concentration, hydrolysates were submitted to ultrafiltration through membranes of 3 kDa pore size (Millipore Corporation, Billerica, MA, USA) and permeates were analysed by the DC protein assay (Biorad) using BSA as standard.
