Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R): Assertion (A): Food with low initial microbial load always have longer shelf life.
Reason (R): Growth conditions during storage are more critical than initial contamination levels. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Shelf life depends more on storage conditions than initial contamination

Answer 1

The Correct Option is D

Concept:
Shelf life of food depends on both initial microbial load and storage conditions such as temperature, humidity, and oxygen availability.

Step 1: Analysis of Assertion (A)

• Low microbial load helps in longer shelf life.
• However, the word “always” makes the statement incorrect.
• Even low contamination can lead to spoilage under poor storage conditions.

Step 2: Analysis of Reason (R)

• Storage conditions (temperature, moisture, etc.) strongly influence microbial growth.
• Even small contamination can multiply rapidly under favorable conditions.
• Hence, Reason (R) is correct.

Step 3: Logical Evaluation

• Assertion is incorrect due to absolute statement.
• Reason is correct and scientifically valid. Final Conclusion: \[ \boxed{\text{(A) is not correct but (R) is correct}} \] \[ \boxed{\text{Option (D)}} \]
