Assertion (A) : Modified atmospheric packaging using $CO_2$ to extend the shelf life of perishable foods.
Reason (R) : The $CO_2$ encourage the growth of spoilage microorganisms by altering intracellular pH.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion (A) Correctness
The statement asserts that Modified Atmospheric Packaging (MAP) using $CO_2$ helps extend the shelf life of perishable foods. This is correct. MAP involves altering the atmosphere inside food packaging to slow down spoilage processes like oxidation and microbial growth, thereby extending product freshness and shelf life.
Reason (R) Correctness
The statement claims that $CO_2$ encourages the growth of spoilage microorganisms by altering intracellular pH. This is incorrect. Higher concentrations of $CO_2$ in MAP typically inhibit the growth of many aerobic spoilage bacteria and pathogens. While $CO_2$ does dissolve in the food moisture to form carbonic acid (lowering pH), this effect generally hinders rather than encourages microbial growth.
Conclusion
Based on the analysis:
- Assertion (A) is correct.
- Reason (R) is incorrect.
Therefore, the most appropriate answer is that (A) is correct but (R) is not correct.
