2. Rice Fortification
๏ Rice is staple food for more than 3 billion people; 430
million metric tons rice produced annually and 13
countries account for 85-88% global production &
consumption.
๏ Rice fortification is the enrichment of rice with
essential vitamins and minerals post-harvesting to
increase its nutritional value.
3. Need for fortification
๏ To prevent nutritional anemia
๏ To prevent neural tube birth defects
๏ To increased productivity
๏ To improve economic progress
7. Dusting
๏ Dusting the rice grains with the powder form of the
micronutrient premix
๏ Fortificants will stick to the grain surface because of
electrostatic forces
๏ This rice should not be rinsed and cooked in excessive
amounts of water and then drained as enrichment and
other water soluble vitamins and minerals will be lost.
๏ So this technology is not appropriate in developing
countries where rice is washed and rinsed before
cooking.
9. ๏ The artificial and fortified kernels produced through
hot extrusion share similar properties with natural
grains (transparency, sheen, consistency, and flavor).
๏ The fortified kernels from cold extrusion are opaque
and slightly off-color.
๏ Coated kernels often have a distinctive color, smell,
and taste that are objectionable to some consumers.
๏ Dusted kernels loose the micronutrient-premix on
their surface with rinsing and washing.
10. ๏ The rice-premix developed is blended with natural
polished rice at about 1:200, 1:100, 1:50 ratio to produce
fortified rice.
๏ Of the 4 methods, dusting is the least expensive and
hot extrusion is the most expensive, although the
latter produces the best quality product and hence
improves acceptance by the consumer
๏ So Hot extrusion may be the best technology for
good quality fortified rice.
11. Micronutrient for fortification
Micronutrient Fortificant form
Iron MFPP (ferric pyrophosphate) / FeSO4
Zinc Zinc oxide
Folic acid Folic acid
Vit B12 Cyanocobalamin
Vit A Vit A palmitate
Thiamin Thiamin
Niacin Niacinamide
Vit B6 Pyridoxine hydrochloride

13. Conclusion
๏ Fortified rice looks, smells and tastes very similar to
non-fortified rice
๏ Hot extrusion can be a great technology for rice
fortification
๏ Rice fortification will help to reduce nutrition related
disorders.
๏ By using affordable technology more number of
countries started producing fortified rice.
