Proteins solubility curve

The solubility of a protein corresponds to its capacity to dissolve in water to form an homogenous solution. Protein solubility profile corresponds to the evolution of its solubility with pH. It is obtained by preparing protein solutions at different pH, centrifugating the solution and measuring the protein content of the supernatant. The protein solubility profile must be measured to define a protein extraction process. High protein solubility is also desired for beverages.
