This study investigated the effects of sodium alginate (SA) and glucono-d-lactone (GdL) levels on the coldset
gelation of porcine myofibrillar protein (MP) at different salt concentrations. The addition of GdL at
0.1 M salt concentration had no effects on cold-set MP gelation, and GdL level higher than 1% was necessary
at 0.3 M salt concentration to form a MP gel. The SA system with 0.5% GdL showed an effect on
MP gelation at 0.1 M salt, while SA with 1.5% GdL could be form a cold-set MP gel at 0.3 M salt level.
The endothermic peaks were reduced or completely disappeared by the addition of GdL more than 1%.
These results indicated that the SA was favorable in forming a cold-set MP gel under low salt concentrations
(1%).
