IIT Roorkee unveils eco-friendly packaging innovation to extend shelf life of fresh produce

INDIA – Researchers at the Indian Institute of Technology (IIT) Roorkee have developed an eco-friendly packaging solution that can extend the shelf life of fruits and vegetables by up to one week.

Led by Prof. Kirtiraj K. Gaikwad and PhD scholar Mr. Pradeep Kumar from the Department of Paper Technology, the innovation centres on a 100% natural ethylene scavenger derived from modified clay minerals.

Ethylene, a natural plant hormone, accelerates ripening and often leads to premature spoilage of fresh produce.

Traditional ethylene scavengers typically rely on synthetic chemicals like potassium permanganate, which pose health and environmental concerns.

In contrast, IIT Roorkee’s new solution leverages naturally abundant and cost-effective clay minerals in optimized ratios to safely and efficiently absorb ethylene gas.

Laboratory tests revealed an impressive 86% efficiency in ethylene adsorption under controlled conditions — dramatically slowing down the ripening process and helping maintain both the nutritional quality and visual appeal of fruits and vegetables.

“This technology addresses the dual challenge of reducing food spoilage and ensuring environmental safety. It is a testament to how innovative research can drive meaningful change,” said Prof. Gaikwad.

“Our packaging solution not only preserves produce longer but also contributes to a cleaner, greener environment.”

The development aligns with India’s national initiatives such as Swachh Bharat Abhiyan and Aatmanirbhar Bharat, underscoring the role of indigenous innovation in addressing global challenges.

Inspired by IIT Roorkee’s long-standing tradition of practical, eco-conscious research, the solution highlights how scientific advancements can support industry needs while promoting sustainability.

Notably, the technology is scalable and now available for licensing — making it a compelling option for the food packaging industry, where demand for safe, sustainable alternatives continues to grow.

Prof. K.K. Pant, Director of IIT Roorkee, emphasized the institute’s commitment to impactful innovation: “At IIT Roorkee, we strive to develop solutions that address real-world challenges. This eco-friendly packaging technology is a prime example of how science can benefit industries, consumers, and the planet. We are proud to lead such transformative efforts.”

With this innovation, IIT Roorkee reinforces its reputation as a hub for research-driven solutions—setting a new benchmark in the intersection of technology, sustainability, and public health.
