Surimi-alginate gels as affected by setting: a study based on mixture design and regression models
2003
Kim, S.M.
Interaction and setting effects on surimi-alginate gels were investigated by D-optional mixture design and analyzed by linear and nonlinear manual or stepwise regression models. Nonlinear model showed significant interactions of surimi-water on water retention ability (WRA) and failure shear stress, and surimi-alginate on whiteness of control (non-set) surimi-alginate gels. But no interaction was found on shear strain of control gels. In set gels, only WRA fitted nonlinear model with interaction terms for surimi-water and alginate-water. Setting increased the gel functionalities such as WRA, whiteness, and shear stress of surimi-alginate gels. The response trace plots showed that WRAs and failure shear stresses of both control and set gels of surimi-alginate were increased by alginate and surimi contents, but decreased by water. However, whiteness was increased by water and surimi contents, but decreased by alginate, while shear strain was increased by surimi content, but decreased by alginate and water.
