The effect of adding fish gelatin on expressible water of surimi gels is shown in Fig. 2. The amount of extracted water increased from 5.8 to 8.8% in grade A surimi gels and decreased from 6.3 to 5.2% in grade FA surimi gels. Grade A surimi gels containing 7.5– 15 g/kg of fish gelatin showed significantly higher values of expressed water than control (P 0.05), indicating that these concentrations of fish gelatin induced a loss in the water holding capacity (WHC) of gels. On the other hand, grade FA surimi gels containing 7.5–15 g/kg of fish gelatin showed significantly lower values than control, indicating a beneficial effect.
