                  3-pH

                  • Microorgisms affected by pH of foods, since they do not have any mechanism to

                   adjust their internal pH.

                  • Each microorganism has an optimum pH where it grow best

                  • Most microbes do not grow within 1pH unit above or below their optimum.
