Atlantic croaker (Micropogon undulatus), Mexican flounder (Cyclopsetta chit
tendeni) and Northern kingfish (Menticirrhus saxatilis) are warm water spec
ies abundant in the Gulf of Mexico, usually obtained as shrimp by-catch. Ge
ls from these species were obtained by several treatments: (1) setting at 2
5 degreesC/3 h followed by cooking at 90 degreesC/15 min; (2) setting at 40
degreesC/30 min and 90 degreesC/15 min; (3) 90 degreesC/15 min (control).
Three different additives were studied: 0.66% ammonium chloride, 0.2% EDTA
and 0.2% calcium chloride. The setting phenomenon was induced at 40 degrees
C in the three species. 0.2% calcium chloride improved shear stress and she
ar strain in surimi gels from Atlantic croaker and Northern kingfish. 87.98
and 98.49 kPa for shear stress, and 2.23 and 2.15 for shear strain were ac
hieved, respectively. (C) 2001 Elsevier Science Ltd. All rights reserved.
