This tech makes perishable food last months without a fridge

In the U.S., households throw out around 30 million tons of food each year—nearly twice as much as the produce wasted on farms. In some other parts of the world, the situation flips: Because of a lack of infrastructure and unreliable electricity, food often can’t be refrigerated, and it rots before it can be sold to consumers.

But new technology could help eliminate the need for cold storage. Farther Farms, a startup based in upstate New York, developed a new type of pasteurization that makes food last longer, so perishable food can sit on a shelf instead of in a fridge. As a proof of concept, the company made packaged french fries—food that would normally be sold frozen—that can sit at room temperature for 90 days before it’s eaten. Even better: The process doesn’t use artificial preservatives.

Cofounder Vipul Saran developed the tech as a grad student at Cornell University. Saran grew up in a farming family in India and saw how challenging it was to deliver produce (in their case, potatoes) in the supply chain. The necessary infrastructure was minimal and expensive to use; refrigerated shipping containers sometimes cost more than the value of the produce itself. At Cornell, he started exploring an alternative. “The whole goal was, basically, how can we look into new, innovative food processing technologies that can allow us to create value-added food products from these perishable food products, which avoids the need and the dependency as much as possible on refrigeration and freezing?” he says.
