Question

In TBA test colour formation is due to the reaction of TBA with:

• A. Malondialdehyde
• B. Ketones
• C. Linoleic acid
• D. PUFA

Hint:

TBA test: reacts with malondialdehyde.
Colour complex formed.
Measures lipid oxidation.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
TBA test measures lipid oxidation.
Colour formation is specific.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the TBA test principle.
Step 3: Detailed Explanation:
In the TBA test, colour formation is due to the reaction of TBA with malondialdehyde (MDA).
MDA is a secondary oxidation product.
Ketones, linoleic acid, and PUFA are not directly involved.
Thus, malondialdehyde is the correct compound.
Step 4: Final Answer:
Colour formation is due to reaction with malondialdehyde.
Hence, the correct option is (A). \bigskip
