Changes of pH in β-Lactoglobulin and β-Casein Solutions during High Pressure Treatment

Figure 3

Pressure dependence of pH of aqueous solutions of B at 1.00 mg/mL () and 3.00 mg/mL (●), 1.00 mg/mL (▼), and B + (1 : 1 mg/mL) (★), all with an initial pH of 7.0. The change in pH, , is calculated from spectral data according to (1). The dashed line represents the ΔpH calculated from the changes of (1.00 mg/mL) and (1.00 mg/mL) according to (3).
