Question

Identify the correct statements about oil processing:
A. Oil expelling is a mechanical method
B. Solvent extraction improves oil yield
C. Hydrogenation increases unsaturation in oil
D. Refining removes impurities in oil processing
E. Hydrogenation does not improve shelf life of oil
Choose the correct answer from the options given below:

• A. A, B, C only
• B. A, B, D only
• C. A, B, E only
• D. A, B, C, D only

Hint:

Hydrogenation = more stable, less unsaturated.

Answer 1

The Correct Option is B

Concept: Oil processing includes extraction, refining, and modification techniques such as hydrogenation.

Step 1: Evaluating Statement A.
Oil expelling:
• Uses mechanical pressure Correct.

Step 2: Evaluating Statement B.
Solvent extraction:
• Extracts more oil than mechanical methods Correct.

Step 3: Evaluating Statement C.
Hydrogenation:
• Adds hydrogen to double bonds
• Decreases unsaturation Thus, incorrect.

Step 4: Evaluating Statement D.
Refining:
• Removes gums, pigments, free fatty acids Correct.

Step 5: Evaluating Statement E.
Hydrogenation:
• Improves oxidative stability
• Increases shelf life Thus, statement is incorrect.

Step 6: Final selection. \[ A, B, D \] Final Conclusion:
Option (2) is correct.
