Micronized Dispersible Ferric Pyrophosphate (MDFP) in Extruded Rice Desserts: High Iron Bioavailability and Good...

Area of Science:

• Nutritional Science
• Food Technology
• Public Health

Background:

• Iron deficiency anemia is a critical global health issue, particularly affecting children.
• Traditional rice-based foods often lack sufficient iron bioavailability.
• Developing effective delivery systems for iron fortification is essential.

Purpose of the Study:

• To assess the efficacy of an extruded rice matrix as a carrier for micronized dispersible ferric pyrophosphate (MDFP).
• To evaluate iron bioavailability in rice desserts fortified with MDFP using cow's milk or soy soluble protein extract.
• To determine the sensory acceptance of these fortified rice desserts by children.

Main Methods:

• Rats were fed diets with MDFP incorporated into extruded rice (with cow's milk or soy extract), ferrous sulfate control, or pure MDFP control.
• Iron nutritional status was assessed through recovery.
• Gene expression analysis of key iron metabolism proteins was performed.

Main Results:

• Fortified groups showed significantly higher iron status recovery compared to controls.
• The extruded rice matrix enhanced MDFP bioavailability, likely by reducing aggregation.
• Fortified rice desserts had satisfactory sensory acceptance among school-aged children.

Conclusions:

• Incorporating MDFP into an extruded rice matrix is an effective strategy for improving iron bioavailability.
• This technology offers a viable and practical approach for developing fortified rice desserts to combat iron deficiency anemia.
• The findings support the application of this method in school feeding programs and the food industry, especially for vulnerable populations.
