Fortified and Irradiated Milk
View Complete Answer & Explanation
Question (English)
Which of the following pair is correctly matched regarding special types of milk?
- Both: Fortified milk is Mineralized & Vitaminized milk; Irradiated milk – Vitamin D content increased by UV exposure ✓ Correct
- Fortified milk only – Mineralized & Vitaminized milk
- Irradiated milk only – Vitamin D content increased by UV exposure
- None of the above
Explanation:
Correct Answer: Both statements are correct
- Fortified milk: Milk that has been enriched with added minerals and/or vitamins beyond its natural content — hence called Mineralized & Vitaminized milk. Example: Vitamin D-fortified milk, calcium-fortified milk.
- Irradiated milk: Milk exposed to UV rays, which converts 7-dehydrocholesterol in milk fat into Vitamin D (cholecalciferol). This increases the Vitamin D content of milk without adding any chemical supplements.
Key Vitamins and Milk Processing
- Vitamin D: Increased by UV irradiation (irradiated milk).
- Vitamin B1 (Thiamine) & Vitamin C: Lost/destroyed during pasteurization and sterilization.
- Butter: Contains all fat-soluble vitamins (A, D, E, K).
- Cow milk: Particularly rich in Vitamin A and carotene.
- Milk: Good source of thiamine and riboflavin; poor source of Vitamin C.
Why Other Options Are Wrong
- Options B and C are individually correct but incomplete — since both pairs are correctly matched, 'Both' is the right answer.
