Bio-fortification: A Strategy for Improved Nutritional Value in Fruit Crops

Abstract

Bio-fortification, or biological fortification, enhances the nutritional value and bioavailability of food crops through traditional breeding, modern biotechnology, and agronomic practices. With hunger and malnutrition posing significant socio-economic and health challenges, achieving the UN Sustainable Development Goal 2 (UN-SDG2) by 2030 remains a critical global objective. In fruit crops such as mango, banana, guava, citrus, papaya, apple, pear, and strawberry, bio-fortification efforts focus on increasing essential nutrients like beta-carotene, vitamin C, iron, and zinc. These biofortified fruits offer a cost-effective solution to improve nutrition, particularly for vulnerable populations, helping to mitigate the risks of hidden hunger and malnutrition. While genetic modifications accelerate nutritional improvements, challenges such as regulatory approvals and public acceptance persist. Although food supplements and dietary diversification provide short-term relief, bio-fortification represents a sustainable, long-term strategy to combat malnutrition. Recent advancements in research have demonstrated the potential of bio-fortified crops to address micronutrient deficiencies effectively. Policy initiatives and global expansion efforts are further supporting the adoption of bio-fortification, emphasizing its role in improving food security and nutritional outcomes worldwide. This review highlights the progress in bio-fortification research, the importance of policy frameworks, and the growing global momentum behind this approach. By integrating bio-fortification into agricultural systems, it is possible to create a resilient and nutritious food supply, contributing significantly to the fight against malnutrition and the achievement of global food security goals.
