Abstract
In order to utilize the silkworm larvae (Bombyx mori) protein, defatted silkworm protein was hydrolysed by four enzymes (pepsin, trypsin, neutrase and alcalase) at various hydrolysis times (6, 12, 18, 24 and 30 hr) and suspension concentrations (2, 5, 10, 15 and 20%). Protein solubility index, ACE (angiotensin converting enzyme) inhibitory activity and antioxidative activity of silkworm protein hydrolysates were investigated. The optimum condition of hydrolysis was 10% suspension concentration and 18 hr. Protein solubility index of trypsin treatment was higher than other enzyme treatments. ACE inhibitory activity and $IC_{50}$ value of antioxidative activity of neutrase treatment were 86.16% at $100\;{\mu}g/mL$ and $352.75\;{\mu}g/mL$, respectively; also, these values were higher than other enzyme treatments.
