Step 1: Understanding the Concept:
Autoxidation produces various compounds.
Some compounds are responsible for off-flavours.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the compounds causing oxidized flavour.
Step 3: Detailed Explanation:
Aldehydes impart oxidized flavour to milk products.
They are produced during autoxidation.
Hydroperoxides are intermediates.
Fatty acids are not responsible.
Polyperoxides are also intermediates.
Thus, aldehydes cause oxidized flavour.
Step 4: Final Answer:
Aldehydes impart oxidized flavour.
Hence, the correct option is (D).
