摘要

Heads and guts of threadfin bream, by0products from surimi industry, were ground and dried to 6.85/100 moisture content. Dried fish parts containing 49.92/100 protein, 9.23/100 fat and 31.12/100 ash (dry basis), was used as raw material for the study of fist protein hydrolysate(FPH) production. Pretreatment conditions of dried fish parts were compared among 3 groups: control(soaked in distilled water), heating in autoclave and soaking in alkali. Conditions of enzyme hydrolysis were investigated. The results showed that alkali treatment (NaOH at pH 8.5, 90 min. 10°C) followed by enzyme hydrolysis (alcalase activity 2.4 AU/gm, 0.075 ml per 100 gm dried fish) 150 min at 60°C, produced FPH with the highest emulsifying capacity.
