Question

Which of the following is a unique example of emulsion technology?

• A. \(\text{Butter making}\)
• B. \(\text{Ice cream preparation}\)
• C. \(\text{Cream separation}\)
• D. \(\text{Chips making}\)

Hint:

Butter is a water-in-oil emulsion, whereas milk and cream are oil-in-water emulsions.

Answer 1

The Correct Option is A

Step 1: Understanding emulsions.
- An emulsion is a mixture of two immiscible liquids, such as oil and water.
- Butter formation involves phase inversion, converting an oil-in-water emulsion (milk) into a water-in-oil emulsion (butter).
Step 2: Explanation of incorrect options.
- (B) Ice cream preparation: Uses emulsifiers but is not a true emulsion-based process.
- (C) Cream separation: Involves centrifugation, not emulsion formation.
- (D) Chips making: Not related to emulsions.
Step 3: Selecting the correct option. Since butter making is a clear example of emulsion formation, the correct answer is (A) Butter making.
