Question:medium

Read the below-given statements pertaining to modified atmosphere packaging.
(A). The solubility of \(CO_2\) in aqueous foods decreases with moisture increase and temperature decrease.
(B). Displacement of oxygen by \(N_2\) acts to block out the oxidative chemical and physiological reactions, preserving the food quality.
(C). Combined high \(O_2\) (80-90%) and \(CO_2\) (10-20%) have been suggested to provide adequate suppression of microbial growth.
(D). Concentrations of \(CO_2\) in excess of 5% (v/v) inhibit the growth of most food spoilage bacteria especially psychrotrophic species such as Pseudomonas spp.
Choose the correct answer from the options given below:

Show Hint

Remember that the solubility of carbon dioxide (\(\text{CO}_2\)) in water increases as the temperature decreases. This is why chilled carbonated beverages retain their gas better than warm ones, and why MAP works most effectively under refrigeration.
