Ph measurement method
WebbpH is a measure of the relative amount of hydrogen and hydroxide ions in an aqueous solution. In any collection of water molecules a very small number will have dissociated … WebbControlling the pH of cream helps in imparting specific flavor and consistency to the product. For instance, preparing sweet butter from pasteurized cream requires the pH to be controlled between 6.70 and 6.85 whereas for preparing sour butter, the cream has to be acidified to a pH of 4.6 to 5.0. Therefore monitoring its pH is crucial.
