We present a method to optically study the pH value of intransparent media under pressure. To this end, we prepare and use immobilized pH-value indicators. The indicators are brought into contact to the medium and their optical signal is read out in reflection with a spectrometer. The pH value and pressure response of the indicator were calibrated with imidazole buffers. As an example for its applicability to foodstuff, we study the pressure-induced pH-value change of fat and meat pastes.
