Figure 1 - Model prediction for the effect of frozen storage time (months) and pressure (MPa) on the acid phosphatase activity (nmol p-NP/min/g). Pressure holding time was fixed at 2.5 min.
Figure 2 - Model prediction for the effect of frozen storage time (months) and pressure (MPa) on the cathepsin B activity (FU/min/g). Pressure holding time was fixed at 5 min.
Figure 3 - Model prediction for the effect of pressure (MPa) and frozen storage time (months) on the cathepsin D activity (µg tyrosine/min/g). Pressure holding time was fixed at 0 min.
