The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Antioxidants can be synthetic (chemically synthesized) or natural (isolated from plant, animal, or microbial sources).
Step 2: Detailed Explanation:
- BHT (Butylated Hydroxytoluene), TBHQ (Tert-Butylhydroquinone), and Ethoxyquin: These are synthetic chemical antioxidants commonly used in foods and animal feeds.
- Phospholipids: These are naturally occurring lipid molecules (e.g., lecithin found in soybean, egg yolk) that possess natural antioxidant and synergist properties in oils.
They form protective barriers around lipid droplets and synergize with tocopherols to retard autoxidation.
Step 3: Final Answer:
The natural antioxidant among the options is Phospholipids, which corresponds to option (D).
