Designer Rice by CSIR-NIIST- Solution to Dual Challenge of Traditional White Rice
The “Designer Rice” (or “Smarter Rice”) technology developed by the CSIR-National Institute for Interdisciplinary Science and Technology (CSIR-NIIST) in Thiruvananthapuram addresses a massive public health challenge.
Polished white rice is a staple for over half the global population, but it poses a dual challenge: it triggers sharp postprandial blood glucose spikes (contributing heavily to Type 2 diabetes) and lacks essential micronutrients and protein, perpetuating what nutritionists call “hidden hunger.”
The breakthrough by CSIR-NIIST resolves this dual burden without requiring consumers to alter their deeply ingrained dietary habits.
The Technology: How it Works
Unlike genetically modified organisms (GMOs), Designer Rice is a non-GMO food-processing innovation built on advanced extrusion technology.
· Upcycling Broken Grains: The process begins by taking broken rice grains (a common agricultural by-product) and milling them into a fine flour.
· Nutrient Fortification: This flour is uniformly blended with precise ratios of plant-based proteins and a concentrated micronutrient premix.
· Restructuring: The enriched mixture is passed through a hot extruder under controlled temperature and pressure, which cuts and shapes the matrix back into uniform grains. The final product closely mirrors the appearance, texture, and cooking properties of natural polished white rice.

The Solution to the Dual Challenge
The nutritional profile of this re-engineered staple directly targets metabolic health and systemic malnutrition simultaneously:
| Feature | Traditional White Rice | CSIR-NIIST Designer Rice | Health/Societal Impact |
| Glycaemic Index (GI) | High | Low | Moderates’ carbohydrate digestibility; prevents sudden blood sugar spikes; supports diabetes management. |
| Protein Content | Low | High | Delivers more protein, helping bridge the severe protein-energy malnutrition gap in rice-dependent regions. |
| Micronutrients | Stripped during polishing | Enriched with Iron, Folic Acid, & Vitamin B12 | Actively combats nutritional anemia and neural tube defects, particularly in vulnerable women and children. |
| Dietary Fibre | Negligible | Significantly Improved | Enhances digestive wellness and promotes prolonged satiety (fullness). |
A Circular Economy Win: By utilizing broken rice as its primary raw material, the technology provides an affordable value-addition loop for millers, minimizes post-harvest losses, and keeps production highly scalable.
Commercialization and Scale
To transition this innovation from a laboratory success to public dinner plates, CSIR-NIIST officially transferred the technology to commercial giants, including Tata Consumer Products Limited (TCPL) and SS Soul Foods. This commercial path aims to achieve large-scale deployment through consumer retail and potentially integrate the grain into national public health frameworks such as the Public Distribution System (PDS) and mid-day meal schemes.
For his pioneering work on this technology, Dr. C. Anandharamakrishnan (Director, CSIR-NIIST) was honored with the prestigious Tata Transformation Prize.
