Micronutrient deficiency maintains the cycle of poverty. A steady intake of essential nutrients is not available in developing areas due to factors of socioeconomic constraints, limited variety of food sources, and single-carbohydrate based diets. Fortification of a staple food is an effective way of combating micronutrient deficiencies.
The food product developed in this study is an extruded, micronutrient-fortified, rice-shaped premix. The target rice premix formulation contains iron, zinc, a B-vitamin complex, and vitamin A and is blended with market rice in a 1:100 ratio. Iron furthers the oxidation of vitamin A, thus various micronutrient encapsulation techniques and antioxidant systems are explored in this study.
It is technically and economically feasible to combine the micronutrients in a single formulation by introducing efficient physical and chemical barriers. Optimal formulation designs used coated vitamin A sources and retained >85% vitamin A at 6 months storage with acceptable sensory attributes.
