The World Health Organization (WHO) defines fortification as the intentional addition of essential vitamins and minerals to improve the nutritional quality of the food supply and provide public health benefits with minimal risk .<\/p>\n\n\n\n<p>Common nutrients added to fortified rice include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Iron<\/strong>: To combat anemia and support cognitive development<\/li>\n\n\n\n<li><strong>Zinc<\/strong>: Essential for immune function and growth<\/li>\n\n\n\n<li><strong>Vitamin A<\/strong>: Critical for vision and immune health<\/li>\n\n\n\n<li><strong>Folic acid and B-complex vitamins<\/strong>: Important for cell development and energy metabolism<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Fortified Rice is Made: The Extrusion Process<\/h2>\n\n\n\n<p>While several fortification methods exist\u2014including coating, dusting, and parboiling\u2014extrusion technology has emerged as the most effective and widely adopted approach . This is where twin-screw extrusion technology, discussed in our previous articles, plays a crucial role.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer-768x1024.jpg\" alt=\"\" class=\"wp-image-6883\" style=\"width:804px;height:auto\" srcset=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer-768x1024.jpg 768w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer-225x300.jpg 225w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer-1152x1536.jpg 1152w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer-9x12.jpg 9w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer-600x800.jpg 600w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/mixer.jpg 1279w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p>The extrusion process for fortified rice involves several steps:<\/p>\n\n\n\n<p><strong>1. Formulating the Premix:<\/strong> A vitamin-mineral premix is carefully formulated, containing specific amounts of micronutrients such as iron, zinc, folic acid, and vitamin A. This premix is blended with rice flour, typically made from broken rice\u2014an underutilized by-product of rice milling . Using broken rice adds a sustainability dimension, creating value from what would otherwise be a low-value product .<\/p>\n\n\n\n<p><strong>2. Extrusion Cooking:<\/strong> The blended mixture is fed into a twin-screw extruder, where water is added to form a dough. Inside the barrel, the material is subjected to controlled heat (typically 70-110\u00b0C for hot extrusion) and mechanical shear . This cooks the starch and creates a homogeneous, plasticized mass. The extrusion process can be either &#8220;hot extrusion&#8221; (70-110\u00b0C), which produces partially pre-cooked kernels with sheen and transparency similar to natural rice, or &#8220;cold extrusion&#8221; (below 70\u00b0C), which creates opaque, uncooked kernels .<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-1024x768.jpg\" alt=\"\" class=\"wp-image-6634\" srcset=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-1024x768.jpg 1024w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-300x225.jpg 300w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-768x576.jpg 768w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-1536x1152.jpg 1536w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-16x12.jpg 16w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2-600x450.jpg 600w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/double-screw-extruder2.jpg 1706w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>3. Shaping into Kernels:<\/strong> The cooked dough is forced through a die that shapes it into rice-like kernels. A rotating cutter chops the extruded strands into grains that closely mimic the size and shape of natural rice .<\/p>\n\n\n\n<p><strong>4. Drying and Polishing:<\/strong> The freshly extruded fortified rice kernels (FRKs) are dried to reduce moisture content, preventing spoilage and ensuring shelf stability. Some facilities include polishing steps to further enhance the visual similarity to conventional rice .<\/p>\n\n\n\n<p><strong>5. Blending:<\/strong> The final critical step involves blending the FRKs with regular polished rice, typically at a ratio of 1:50 to 1:200 (0.5% to 2% fortified kernels). This ensures that each serving of rice delivers the target nutrient levels while remaining visually and texturally indistinguishable from ordinary rice .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Nutritional and Public Health Impact<\/h2>\n\n\n\n<p>Fortified rice has demonstrated significant potential in addressing malnutrition:<\/p>\n\n\n\n<p><strong>Combating Micronutrient Deficiencies:<\/strong> A Cochrane systematic review informs WHO recommendations that fortifying rice with iron is effective for improving iron status in populations where rice is a staple food . Similarly, fortification with vitamin A and folic acid can improve vitamin A nutrition and folate status, respectively .<\/p>\n\n\n\n<p><strong>Retention of Nutrients:<\/strong> Advanced extrusion techniques show good nutrient retention. For example, supercritical fluid extrusion has demonstrated 55-58% retention of vitamin A and 64-76% retention of vitamin C in fortified puffed rice products . Importantly, extrusion processing can also increase resistant starch content\u2014from 12.42% to 16.50% in one study\u2014potentially offering benefits for glycemic control .<\/p>\n\n\n\n<p><strong>Sustainability and Value Addition:<\/strong> Using broken rice\u2014a milling by-product\u2014for FRK production adds economic value and reduces waste . This creates additional income streams for rice millers while producing a nutritionally enhanced product.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-1024x768.jpg\" alt=\"\" class=\"wp-image-6886\" srcset=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-1024x768.jpg 1024w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-300x225.jpg 300w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-768x576.jpg 768w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-1536x1152.jpg 1536w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-16x12.jpg 16w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven-600x450.jpg 600w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/Oven.jpg 1706w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Fortified Rice in Public Health Programs<\/h2>\n\n\n\n<p>Governments and international organizations have increasingly adopted fortified rice as a public health intervention.
