Crops with Enhanced Nutritional Value (Biofortification)
Development of genetically modified crops to improve their nutritional content, such as Vitamin A-enriched rice (Golden Rice), to combat malnutrition.
What is Crops with Enhanced Nutritional Value (Biofortification)?
The process of increasing the density of vitamins and minerals in a crop through plant breeding or genetic engineering.
Key points
- Understand the concept and importance of biofortification.
- Differentiate between biofortification and other methods of nutrient enhancement.
- Identify examples of biofortified crops and their benefits.
- Explain the role of genetic engineering in developing biofortified crops.
Common exam trap
Confusing biofortification with fortification (adding nutrients during processing).
