Abstract:

Soybean protein hydrolysates were prepared by enzymatic hydrolysis with alcalase. Inhibitory activities of enzymatic hydrolysates and the purification fractions to angiotensin I converting enzyme (ACE) were determined for evaluating their hypotensive effects. Results showed that both enzymatic hydrolysates and purified fractions with smaller molecular weights exhibited higher hypotensive activity. However, exonuclease treatment could result in the improvement of flavor and reduction of hypotensive activity for hydrolysates.

Key words: soybean protein, alcalase, hydrolysis, hypotensive effect
