Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Microbial mould butters defect, of condensed milk is one of the major defect.
Reason (R): Contamination with growth of the mould Aspergillus niger followed by presence of oxygen in the head space of cans.
Choose the correct option.

• 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:

Oxygen presence in cans = major cause of mould growth.

Answer 1

The Correct Option is A

Concept: Microbial spoilage in condensed milk occurs when contamination happens and favorable conditions exist for microbial growth.

Step 1: Understanding mould defect.

• Caused by fungal contamination
• Appears as surface growth

Step 2: Role of Aspergillus niger.

• Common spoilage mould
• Grows in presence of oxygen

Step 3: Headspace oxygen.

• Oxygen in cans supports mould growth

Step 4: Linking statements.
Assertion is true.
Reason correctly explains cause.

Step 5: Conclusion.
Both correct and Reason explains Assertion.
