Question

Assertion (A): Whole milk powder produced from nozzle atomiser contains less free fat than from rotary atomizer.
Reason (R): The concentrated milk is forced under higher pressure through a small orifice of nozzle atomiser and is atomised instantly.
In light of the above statements, choose the correct answer from the options given below:

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

Hint:

Nozzle atomizer: higher pressure, instant atomisation, less free fat.
Rotary atomizer: produces more free fat.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Nozzle and rotary atomizers differ in operation.
They affect the properties of milk powder.

Step 2: Key Formula or Approach:
No specific formula.
Need to understand atomization.

Step 3: Detailed Explanation:
Assertion A: Nozzle atomizer produces less free fat - true.
Reason R: Higher pressure through small orifice causes instant atomization - true.
The reason explains why less free fat is produced.
Thus, both A and R are true, and R explains A.

Step 4: Final Answer:
Both (A) and (R) are true and (R) is the correct explanation of (A).
Hence, the correct option is (A).
