Biofortification and its Approaches is a presentation that explores the science and methods behind this sustainable approach to improving human nutrition. It covers the different approaches to biofortification, including traditional breeding, genetic engineering, and agronomic techniques. The presentation also discusses the benefits of biofortification and its potential to help address the global challenge of micronutrient malnutrition. Here are some of the key topics covered in the presentation: What is biofortification? Why is biofortification important? What are the different approaches to biofortification? The benefits of biofortification Case studies of biofortified crops The future of biofortification The presentation is suitable for a wide audience, including students, researchers, policymakers, and anyone interested in learning more about this promising approach to improving human nutrition. Keywords: biofortification, nutrition, micronutrient malnutrition, sustainable agriculture, crop breeding, genetic engineering, agronomic techniques

1. Approaches of
BIOFORTIFICATION

2. Biofortification
● Breeding food crops to improve
their nutritional value.
● Improved protein, oil, vitamins,
minerals and micronutrients.
● Satisfy hidden hunger.
● Different from direct food
fortification.

3. Biofortification
● Addition of nutrients directly to a
food to improve taste and
quality.
● Relatively inexpensive and easy
to implement.
● Examples: Adding salt to flour,
or iodine to salt.
● Crops are bred to have higher
levels of essential nutrients.
● Time-consuming and expensive
to develop a biofortified crop.
● Examples: Breeding rice with
higher iron content.
Fortification

4. Approaches
1. Agronomical: Fertilizers and
agricultural practices.
2. Conventional: Crossing crop
varieties to get new varieties.
3. Transgenic: Inserting genes to
the crops.

5. 1. Agronomic Biofortification
● Agronomic biofortification involves enhancing the nutrient content of crops
by optimizing soil and crop management practices, such as using the
right fertilizers and irrigation methods.
● Adding zinc to the soil to help wheat plants absorb more zinc, resulting in
more nutritious wheat for human consumption.
● To improve the nutrient quality of staple crops in a cost-effective and
sustainable manner.

6. 2. Conventional Biofortification
● Conventional biofortification is the traditional breeding of crops to
increase their nutritional content through selective crossbreeding and
hybridization.
● Developing biofortified rice varieties with higher iron content through
selective breeding.
● To create nutrient-rich crop varieties that are accessible and acceptable
to communities.

7. 3. Transgenic Biofortification
● It's like "genetic supercharging" to insert or modify specific genes
responsible for nutrient accumulation into plants, with the help of genetic
engineering.
● Inserting genes for vitamin A into rice to create "Golden Rice" rich in
provitamin A (beta-carotene).
● To rapidly develop crops with significantly enhanced nutrient levels to
address specific nutrient deficiencies in populations.
