Inside Farther Farms’ mission: Using french fries to make the food system more sustainable

Écrit par abadmin

Mike Annunziata is a firm believer in two things: Reducing refrigeration will help a lot of the world’s problems, and french fries can help get there.

His problem with refrigeration is largely environmental. It eats up about 15% of all of the world’s energy consumption, Annunziata said, quoting research published in Food Research International in 2010.

The food sector accounts for about 30% of the world’s total energy consumption and around 22% of all greenhouse gas emissions, according to the Food and Agriculture Organization of the United Nations. And when the electricity for refrigeration, the manufacture of that refrigeration equipment and greenhouse gases produced by lost refrigerants are taken into consideration, refrigerated storage can account for 10% of a product’s carbon footprint, according to statistics from the Global Cold Chain Alliance.

“It’s crazy if you think about it,” Annunziata said. “We have refrigerators or freezers in every home. Frozen refrigerated trucks moving food all around the world. Storage warehouses keeping food refrigerated or frozen to have higher quality [and be] more convenient.”

Annunziata sees two potential solutions to this problem: Either make refrigeration more efficient or reduce the need for refrigeration. He’s chosen the latter, and is using the technology of supercritical fluids to make ordinarily frozen food shelf-stable with his company Farther Farms.

At its facility in the former Eastman Kodak campus in Rochester, New York, Farther Farms makes fresh potatoes into fries, treats them with supercritical carbon dioxide, and packages them. The packages can travel wherever they need to go without refrigeration, and the fries are ready for the fryer.

Before a virtual tour of Farther Farms’ first-in-the-world facility, Annunziata, co-founder and CEO, said that the company’s ultimate goal is to cut down on the amount of food that needs to be refrigerated and frozen. It’s not about disrupting french fries. Farther Farms wants to change the way the world thinks about food. 

“It’s not going to happen overnight, but you start with a concept that people can understand,” Annunziata said. “Everybody knows a frozen french fry. Now, they’re going to know a fry that isn’t frozen, and we can bring a product lens to that and say, ‘Here’s a high-quality shelf-stable fry.’ ” 

Weak links in the cold chain

There’s more than just the environmental cost of the cold chain. It also can have an extremely high monetary cost, which is something Farther Farms co-founder and Chief Technology Officer Vipul Saran knows well.

Saran is from India, where his family is in the agriculture and food processing business. He said the biggest challenges they faced were the logistical issues and cost limitations for shipping products that required freezing or refrigeration in the subcontinent. He went to Cornell University to study food tech.

“Those basic challenges were one of the drivers for me to come to Cornell: to look for technology in some form or fashion that could be a plug-and-play [solution] for reducing the dependency on refrigeration and freezing in some manner,” Saran said.

While taking classes in Cornell University’s business school, Saran met Annunziata, who had previously worked in the investment world. Annunziata remembers Saran getting up in front of a class and quantifying the problem he wanted to solve. In India, it cost $3,000 to ship something that needed to be in the cold chain. Something that was shelf stable only cost $90 to ship.

The desire to solve this problem sparked the idea for Farther Farms, which Annunziata and Saran started at Cornell in 2016. The business began in Cornell’s eLab Student Accelerator, then received local business grant funding to keep going. To date, Annunziata said, the company has raised about $10 million.

The company moved into its current home — about 30,000 square feet of a building where Kodak used to make touchscreen technology — last year. The building Farther Farms chose is in an industrial park that already had a lot of the needed infrastructure in place. But there was still significant work required to bring in the right kind of equipment and to make the facility comply with federal food safety regulations. The build out finished in April 2020 — on schedule, despite the onset of pandemic-related shutdowns just weeks earlier — and the company shipped out its first french fries in January.

Farther Farms is just getting started now. Annunziata wouldn’t say how many pounds of french fries the company produces, but it makes a couple of pallets of product a week. There’s a handful of foodservice customers for the fries; Annunziata said that Farther Farms is working to slowly and deliberately scale up its processes to ensure the technology works well and the product is high quality. While the fries currently are only consumed at some New York locations, Annunziata said that product will make a much farther journey as the company grows.

The right tech is supercritical

The way that Farther Farms makes its fries fresh and shelf stable is not a new technology or idea. The company uses supercritical carbon dioxide, which can be produced by pressurizing and heating the gas. When carbon dioxide reaches supercritical status, it exists as both a liquid and a gas at the same time. The existence of supercritical fluids has been known since 1822, and research on supercritical carbon dioxide dates back 90 years.

To Annunziata and Saran’s knowledge, Farther Farms is the only food company using supercritical carbon dioxide in food preservation right now. Saran said he stumbled upon its food application while researching different preservation methods. Cornell University gave Saran access to its experts and to some of its research around uses of supercritical carbon dioxide in food. Supercritical carbon dioxide has a wide array of uses now, including power generation, dyeing fabrics without water, sterilization in a biomedical context and decaffeinating coffee.

The biomedical applications caught Saran’s eye because the supercritical carbon dioxide can inactivate both what he calls “pathogens of concern” and some undesirable natural enzymatic processes. Soon after cutting an apple or potato, it will begin to brown as a part of natural chemistry. But that doesn’t happen with a potato treated with supercritical carbon dioxide.

“It’s not going to happen overnight, but you start with a concept that people can understand. Everybody knows a frozen french fry. Now, they’re going to know a fry that isn’t frozen, and we can bring a product lens to that and say, ‘Here’s a high-quality shelf-stable fry.’ ”

“Doing the very early stage unit cost analysis and understanding how the process would scale compared to other technologies, it sort of felt, and became clearer as we went along, that A, it is technically more advanced in terms of its capabilities against other technologies, and B, it does definitely have a bigger potential in terms of scalability,” Saran said. 

Using supercritical carbon dioxide has one other very important benefit: The french fries are structurally the same. Many other shelf-stable preservation methods today, including canning and retort technology, rely on high heat cooking or high pressure. While these methods are good at preserving food, they cannot be used to preserve the fresh taste or cut structure of french fries. Annunziata pointed out that if Farther Farms used retort technology, it would be making mashed potatoes.

At Farther Farms’ facility, many of the work areas look like a traditional french fry factory. It’s much smaller, given the company’s current scale, but the processes are basically the same.

Annunziata stood in front of a massive mound of russet potatoes, which had been delivered the day before from a Maine farm. The potatoes went up a rolling conveyor belt where workers checked them for quality, removing any rotten ones or rocks. The conveyor belt continued, and a machine peeled and cut the potatoes into shoestring slices. They ran through a blancher, quickly cooking in hot water to stop the browning process.

After blanching, the potato slices roll through ovens to be dried. This is the first big difference between Farther Farms’ process and a conventional french fry factory, which would be oiling and frying the potatoes at this point. As a startup, Annunziata said Farther Farms used what equipment it could find to see if it could do the job. Those drying ovens, he pointed out, are repurposed commercial pizza ovens.
