Describe Anti-microbial Action of Acetic Acid for Preservation of Food

Anti-microbial action of acetic acid for preservation of food:

Since the acetic acid decrease the 13″ of aqueous environment of food, hence this environment are not helpful for growing & increasing microorganism In fact this prohibition is created by undecomposed acetic acid. When P^H is decrease then the undecomposed acetic acid increased. When P^H = 7.0 then the undecomposed acetic acid is 1% but when P^H = 3 then its amount is 98% nearly. undecomposed acetic acid easily enter the cell through cell wall In the cytoplasm CH₃COOH decomposed into H⁺ ion and CH₃COO^– ion

CH₃COOH ↔ CH₃COO^– + H⁺

In this process the concentration of H⁺ ion in cytoplasm increased and P^H decreased that is why essential enzyme system arc hartne4 and the cell is souls to be died. Acetate ion express antimicrobial activity.
