Both liquid and solid wastes from Pacific whiting surimi manufacturing were
characterized and value-added products were recovered. A proteinase in surimi wash
water (SWW) was determined to be cathepsin L with Mr 54,200 on SDS-substrate gel.
Heat treatment and acidification shifted the activity zone to M [subscript r] 39,500. No...
Proteolytic degradation of fish flesh occurring at elevated temperatures is the
primary limitation for the commercial utilization of arrowtooth flounder (ATF).
Characterization of the autolytic activity of ATF muscle incubated at various pHs
and temperatures indicated the involvement of heat-activated proteinases active at
acidic and alkaline pHs. Further characterization of...
