WebpH. Bacteria are sensitive to various pH range. The bacterial species that grow at a pH range above or below the preferred value would not survive. But, bacteria at optimum pH show the best growth in nearly neutral pH, i.e. 6.5-7.5. The acidic pH usually restricts microbial growth, and it is frequently used in food preservation methods. WebThe pH value of a food is a direct function of the free hydrogen ions present in that food. Acids present in foods release free hydrogen ions; the hydrogen ions give acid foods their …
