  1. *ACE inhibitory activity of SEC fractions was tested at 1 μg/ml protein and expressed as mean ± standard deviation (n = 3). Different letters within a column indicate significant differences (p < 0.05) in the percentage of ACE inhibitory activity analysed by one-way ANOVA. SEC fraction highlighted in bold was selected for further analysis.
