In this study, response surface methodology (RSM) was used to evaluate the combined effects of NaCl, glucono-d-lactone (GdL), and
j-carrageenan concentration (0.25%, 0.5%, and 0.75%) on the binding properties of restructured pork under hydrostatic pressure. All the
generated RSM models showed no lack-of-fit and significance at the 0.001 level. The addition of both NaCl and GdL had a significant
effect on color. A significant decrease in pH was shown when the GdL level increased, and subsequently led to a decrease in WHC. However,
increasing the GdL level increased the binding strength. Therefore, the results indicate that a reduction in the NaCl level during
meat restructuring, under pressure treatment, can be achieved by using GdL; and even a low GdL concentration allows for palatable
binding properties in meat restructuring when j-carrageenan is added.
