Question

Which one of the following statements is INCORRECT with respect to Controlled Atmosphere Package (CAP) and Modified Atmosphere Package (MAP) of agro-produce?

• A. CAP and MAP limit microbial as well as biochemical activities.
• B. Gas composition inside a MAP during the storage is continuously monitored and regulated.
• C. CAP implies a greater degree of precision than MAP in maintaining specific levels of the gas composition.
• D. Modification of the atmosphere inside a MAP is achieved by natural interplay between respiration of products and permeation of gases through the packaging film.

Hint:

CAP and MAP are effective packaging techniques that extend the shelf life of perishable produce by controlling the atmosphere, but they differ in the level of control over gas composition.

Answer 1

The Correct Option is B

- Option (A) is incorrect because CAP and MAP primarily focus on limiting microbial and biochemical activities by controlling the atmospheric composition around the stored produce. However, the degree of control for biochemical activities is often more limited in MAP compared to CAP. Therefore, the statement is not entirely accurate.
- Option (B) is incorrect because in MAP, the gas composition inside the package is not continuously monitored and regulated in most cases. The gas composition may change over time depending on the respiration rates of the produce and the permeability of the packaging material, but continuous monitoring is not always part of the process.
- Option (C) is correct because CAP involves a greater degree of control over gas composition compared to MAP, which is typically less precise in its maintenance of specific levels.
- Option (D) is correct because the modification of the atmosphere in MAP is largely due to the natural interplay between the respiration of the produce and the permeability of gases through the packaging film, adjusting the atmosphere over time.
Thus, the correct answers are (A) and (B).
Final Answer: \[ \boxed{(A), (B) \, \text{CAP and MAP limit microbial as well as biochemical activities, and gas composition inside a MAP during storage is not continuously monitored and regulated.}} \]
