Effect of salt and pH on surimi gels made from Pacific whiting (Merluccius productus)

Creator:

Chung, Yun-Chin

Abstract:

The effect of salt (0, 0.9, 1.7, 2.5%) and pH (range 4 to 10) on surimi gels made from Pacific Whiting (Merluccius productus) was investigated. Gel-forming ability was measured by the torsion test. In general, surimi gels increased in gel strength with increased pH. Breaking shear stress increased to a...

Utilization of wastes from Pacific whiting surimi manufacturing : proteinases and protein hydrolysate

Creator:

Benjakul, Soottawat

Abstract:

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...
