Correct Answer – D. CO2 inhibits the microbial activity by forming acid and lowering the pH
Explanation: The normal composition of air is 78% nitrogen and 21% oxygen, rest is made up of carbon dioxide (0.035%), other gases and water vapour. An increase in the proportion of carbon dioxide and/or a reduction in the proportion of oxygen within specified which is achieved by inhibiting bacterial and mould growth, protecting against insect infestation, reducing moisture loss, reducing oxidative changes, controlling biochemical and enzymatic activity to slow down senescence and ripening, CO2 inhibits microbial activity in two ways: it dissolves in water in the food to form mild carbonic acid and thus lowers the pH of the product; and it has negative effects on enzymatic and biochemical activities in cells of both foods and microorganisms.
