During germination processes take place that modify the major components of the grain, such is the case of proteins that are hydrolyzed to generate peptides that can lead to the generation of bioactivity. The objective of the present work was to germinate grains of Pisum sativum to evaluate the effect on the soluble protein content and the anti-inflammatory activity. The grains were subjected to 10 days of germination at 24 °C and relative humidity of 75%. Sprouts were lyophilized, milled, and phenolic compounds were extracted to avoid interferences. Soluble protein content varied significantly during the 10 days of germination. In vitro assays indicate that sprouts protein inhibits thermal denaturation of proteins, protease activity, and stabilize cell membranes. The IC50 values indicate that after germination the bioactivity increased between 1.4 and 3.5 times, with respect to the ungerminated grains. Results indicated that Pisum sativum sprouts may constitute promising health-promoting foods.
