How to Produce Fortified Rice (A Complete Guide)

Fortified rice is enriched with essential vitamins and minerals to combat malnutrition, particularly in regions where dietary deficiencies are common. The process involves coating or extruding rice grains with a nutrient-rich premix. Below is a detailed step-by-step guide to producing high-quality fortified rice.

1. Selecting the Base Rice
Type of Rice: Use long-grain white rice for uniformity (can also be applied to parboiled or brown rice).
– Quality Standards:
– Low broken grain content (<5%).
– Free from impurities (dust, husks, stones).

2. Preparing the Nutrient Premix
Fortified rice typically contains:
Micronutrients:** Iron, zinc, vitamin B1 (thiamine), B3 (niacin), B9 (folic acid), and vitamin A.
Binding Agents:** Food-grade coating materials (e.g., rice flour, wax, or gum arabic) to help nutrients adhere.

Premix Formulation Example:
| Nutrient | Amount per 100g Rice |
|———-|———————-|
| Iron (Ferric Pyrophosphate) | 6–8 mg |
| Zinc (Zinc Oxide) | 2–4 mg |
| Vitamin B1 (Thiamine) | 0.5–1 mg |
| Folic Acid | 150–200 mcg |

*(Exact ratios depend on national dietary guidelines.)*

3. Fortification Methods

A. Dusting (Surface Coating)
– Simplest method: Nutrients are sprayed onto rice as a fine powder.
– Pros:Low cost, easy to implement.
– Cons: Nutrients may rub off during washing.

B. Hot Extrusion (Most Effective Method)
1. Rice flour + nutrients are mixed into a dough.
2. Extruded into rice-shaped kernels (mimicking real rice).
3. Blended with natural rice (usually 1:100 ratio).
– Pros: Resistant to washing, retains nutrients after cooking.
– Cons: Requires specialized machinery.

C. Coating with Wax or Gum
– Nutrients are mixed with a food-grade coating (e.g., beeswax, gelatin).
– Sprayed onto rice, forming a protective layer.
– Used in UNICEF & WFP programs.

4. Blending Fortified Kernels with Regular Rice
– Fortified kernels (1–2%) are mixed with normal rice (98–99%).
– Ensures uniform nutrient distribution.

5. Quality Testing
Nutrient retention check (lab testing for iron, vitamins).
Cooking test(ensures texture remains natural).
Wash test (verifies if nutrients stay after rinsing).

6. Packaging & Storage
Airtight, UV-resistant bags to prevent nutrient degradation.
Shelf life:** 6–12 months (varies based on storage conditions).

Benefits of Fortified Rice
Reduces anemia & vitamin deficiencies.
Cost-effective (adds only ~3–5% to production cost).
No taste or texture change when properly made.

Challenges
Nutrient loss if washed excessively.
Requires strict quality control.

Conclusion
Fortified rice is a powerful tool against malnutrition, especially in school meals and food aid programs. The hot extrusion method is the gold standard for durability, while dusting and coating offer simpler alternatives. Proper blending and packaging ensure the rice retains its nutritional value until consumption.
