What happens when food becomes scarce in the aftermath of disaster?
160 million people are displaced annually due to natural disasters. Beyond the trauma and fear, access to nutritious food becomes a critical challenge for flood victims and relief agencies alike.
During my time at Invent@IITGN, a 6-week intensive summer program, I worked on designing an emergency food-aid solution that doesn't just feed—it grows more nutritious over time.
Starting with impact
The Invent@IITGN program challenged us to research, conceptualize, and prototype a product that meets a significant human need. We chose to focus on flood relief—a problem that affects millions yet remains critically underserved in terms of innovative solutions.
The program structure was unique: weekly pitches to leading industry experts from diverse backgrounds, intensive prototyping cycles, and the requirement to file a provisional patent by the end. This meant every decision had to consider novelty, non-obviousness, practicality, and real-world usefulness.
When food becomes survival, not nutrition
Through analyzing flood documentation, news reports, and expert interviews, we uncovered a critical gap in disaster relief: current food aid prioritizes caloric intake over nutritional adequacy.
Standard emergency food packets contain rice, oil, bread, biscuits, and canned meat. While these satisfy immediate hunger, they lack essential vitamins and minerals found only in fresh produce. For people already traumatized and often injured from floods, poor nutrition delays recovery and increases disease susceptibility.
Limited Supplies
Access to displaced people is restricted. Fresh produce spoils quickly and is difficult to transport in flood conditions.
Storage Constraints
Shelters are overcrowded with limited storage space. Contamination from floodwater is a constant risk.
Nutritional Gaps
Different age groups have different nutritional needs. Current aid fails to provide essential micronutrients for healing.
Despite the existence of specialized nutrition packages, logistical and financial barriers prevent them from reaching those who need them most.
Understanding flood displacement through imagery
Since the program emphasized rapid prototyping over traditional user studies, we adopted a visual research approach. We analyzed hundreds of images documenting floods and their aftermath, building empathy for the pain and suffering experienced by displaced people.
This research deepened our perspective on the systemic challenges: contaminated water everywhere, overcrowded shelters, limited storage, injured victims requiring better nutrition for healing, and the absence of fresh food for extended periods.
Key Research Insights
- Fresh food is nearly impossible to deliver — Floods contaminate local produce and disrupt supply chains for weeks
- Space is at a premium — Shelters are overcrowded, making bulky food storage impractical
- Micronutrient deficiency is critical — Essential vitamins are only present in fresh vegetables, which are unavailable
- Recovery depends on nutrition — Good nutrition accelerates healing from flood-related injuries
Growing food on food
What if emergency food could increase in volume and nutritional value over time? This became our north star.
GreenAid is a unique food-aid packet containing ready-to-eat oat-based porridge embedded with edible seeds. When consumed immediately, it provides complete nutrition. But if stored for 5-7 days, the seeds germinate and grow into nutrient-dense microgreens—without requiring soil.
Microgreens are 4-40 times more nutritious than their mature counterparts, packed with vitamins, minerals, and antioxidants. They grow quickly without soil, using the porridge itself as a growing medium.
How it works
- Immediate consumption — The porridge with edible seeds provides complete nutrition right away
- Delayed consumption — If stored for 5-7 days, seeds germinate into microgreens, significantly increasing nutritional value
- No soil needed — The oat-based porridge serves as the growing medium, eliminating contamination risk
- Flood-proof packaging — Tetra-pak design with 6 protective layers ensures durability in harsh conditions
From kitchen experiments to patent filing
The development process was equal parts design thinking and food science. We explored multiple directions—edible packaging, nutrition concentrates—before landing on the "growing food" concept.
Selecting the microgreen
Not all seeds work. We tested varieties based on growing time, nutritional density, seed edibility, and taste compatibility with the porridge base.
After extensive testing, we selected varieties that germinated reliably in 5-7 days, tasted good both as seeds and microgreens, and provided maximum nutritional benefit.
Perfecting the food base
Countless kitchen hours later, we developed an oat-based porridge recipe that balanced multiple requirements: conduciveness to microgreen growth, taste, shelf life, caloric density, and nutritional completeness.
The recipe needed to support germination without becoming a breeding ground for mold. We incorporated potassium sorbate, a food-grade preservative commonly used in cakes, cheese, and wine, to prevent mold growth while keeping the food safe.
Designing the packaging
The packaging had to solve a complex puzzle: keep seeds separate from the porridge until ready, withstand flood conditions, be space-efficient for transport, and allow users to activate germination without opening the seal.
We turned to origami principles to create a collapsible seed compartment that unfolds internally. The tetra-pak material provides 6 layers of protection against contamination, impact, and moisture.
Packaging Requirements
- Separate compartment for seeds to prevent premature germination
- Weather and impact resistant for flood conditions
- Space-efficient and stackable for optimized logistics
- Easy to activate without opening the seal
- Contamination-free and durable
From prototype to patent
GreenAid was recognized as the 3rd Best Invention at Invent@IITGN 2019. We successfully filed provisional patents in both India and the United States, and our work was featured in The Better India.
Since completing the program, we've been in conversation with multiple organizations interested in developing and launching GreenAid. The next step involves extensive lab testing to ensure food safety before the product can fulfill its purpose of providing relief to flood victims.
What I learned
Key Takeaways
- Crazy ideas need conviction — Our concept was unconventional and initially uncertain. But as we moved from abstract idea to specific details through prototyping, our confidence grew
- Design thinking meets food science — This project taught me to apply design methods to entirely new domains, balancing user needs with scientific constraints
- Expert feedback can substitute user access — Weekly reviews by industry experts from diverse fields provided invaluable insights that compensated for limited user research
- Patenting as a design constraint — Learning to think about novelty, non-obviousness, and prior art added a new dimension to the design process
- Systemic problems need systemic solutions — Addressing food insecurity required understanding logistics, nutrition science, economics, and human behavior simultaneously
GreenAid taught me that product design isn't just about pixels and interactions—it's about deeply understanding human needs and creatively applying principles from multiple disciplines to solve real-world problems.
