Vinegar
-It is a sour liquid formed by fermenting a number of dilute alcoholic liquids into an acetic acid-containing liquid.
-The acetic acid in vinegar destroys microorganisms and prevents food from spoiling.
-Vinegar is utilised as a preservative in both the home and the food business due to its acetic acid content and low pH.
-Acidic conditions also inhibit or prevent germs from growing or surviving; for example, submerging foods in vinegar or a vinegar-sugar mixture helps to preserve food against microbial growth.
Salt and sugar
-They work together to enhance osmotic pressure by destroying germs and slowing decay, stimulating the growth of beneficial bacteria, and promoting flavour.
-It is used to preserve or pickle a wide range of foods, including vegetables, fish products, meat, and spicy fruits.
