Archaeologists in Peru recently uncovered an unusual find: freeze-dried potatoes that date back centuries before the United States was even founded.
The potatoes, known as chuño, were found at the Tambo Viejo site in the Acarí Valley in southwestern Peru. The discovery was recently published in the Journal of Field Archaeology.
The potatoes date back roughly 500 years, to the time of the Inca Empire, according to Phys.org.
Photos of the ancient food show two wrinkled, brownish, freeze-dried potatoes that still appear to retain their shape and color, looking strikingly like modern-day produce.
The preservation of the potatoes is “excellent,” said Lidio Valdez, an archaeology professor at the University of Calgary, who led the excavation.
Valdez told Fox News Digital that the two freeze-dried potatoes are remarkably similar.
“The only difference is the samples found are small, and it seems that over time and due to the aridity of the region, their original size was reduced,” he said. “There is no way one can tell their old age from samples.”

The significance of the discovery, Valdez said, is that it shows the Inca transported food over long distances.
“Freeze-dried potatoes can be produced only at high elevations,” he said. “Afterward, the chuño were stored in state-controlled warehouses, most of them built also at high elevations.”
“Because the Inca state carried out countless projects throughout the realm, the tasks involved thousands of workers, who had to be fed by the state. Thus, state officials likely mobilized volumes of chuño from the warehouses, transporting them in llama caravans.”

At Tambo Viejo, the potatoes were then placed in ceramic vessels and stored underground to avoid food waste.
Potatoes have high water content, Valdez added, which means they don’t survive long “in most places,” making Incan preservation methods particularly impressive.
“Place a potato somewhere in your kitchen just for a month and see what will happen,” he said. “In places with rain and moisture, potatoes will rot quickly. Therefore, freeze-drying was [and] is an effective way to preserve and store them for long periods of time.”

“It appears that in Inca times, large volumes of potatoes were cultivated and freeze-dried, then stored in state-controlled warehouses.”
While freeze-dried potatoes may seem like a specialty ingredient, Valdez said the Inca considered chuño a staple food.
“Those who built the empire … palaces, roads and everything else we admire, [like] Machu Picchu … lived off the chuño,” he said. “It appears that in Inca times, large volumes of potatoes were cultivated and freeze-dried, then stored in state-controlled warehouses.”
The archaeologist said he had hoped to learn more about the Inca recording system, known as khipus, because Tambo Viejo was an administrative center. Instead, he was surprised to uncover evidence of ancient food preservation.
Valdez described Tambo Viejo as “such a great Inca site,” noting that it’s been excavated on and off since 2018.
“Many wonderful finds have been discovered at the site,” he said. “Almost everything found at the site is unprecedented, which makes Tambo Viejo such a unique center.”
The find adds to a growing number of archaeological discoveries that have shed light on the foods eaten — and preserved — by ancient civilizations.
Last year, archaeologists in Italy uncovered preserved food remains in ancient Pompeii, including fruit and fava beans
In April, Swiss officials announced the discovery of a charred 2,000-year-old Roman bread loaf unearthed during an excavation in Windisch, marking the first archaeological find of its kind in the country.

Badenoch blasts 'moaning' female Labour MPs over Burnham jobs 'quota'
Kemi Badenoch has told Labour women to earn a job in Andy Burnham's Cabinet instead of demanding they are handed jobs because of their gender.
The Tory leader lashed out today amid reports that female MPs are demanding the de-facto new prime minister introduce a 50:50 gender split 'quota' in his government.
Amid reports that former foreign secretary David Miliband is being lined up to return to the role, possibly with his brother Ed as Chancellor, one female minister also complained that Burnham could not have 'more Milibands than women' in the top posts.
But in a scathing article in the Times today Mrs Badenoch told them to 'stop moaning' and get chosen on merit instead of retreating into 'more of the failed identity politics that is holding back our country'.
'There are many, many reasons why you shouldn't have any Milibands in the cabinet,' she said.
'But complaining that the boys haven't given them the right jobs or that the boys are taking all the jobs, just shows that Labour's women still don't get it.'
The idea of quotas was also attacked by Baroness Jacqui Smith, Labour's Skills Minister.
Asked by Times Radio if Mr Burnham should reserve jobs for women, she said: 'No, I think what Andy Burnham should be doing is building the very best team around him to change this country.'
A letter written by the Women's Parliamentary Labour Party has called on Mr Burnham to ensure a 50:50 split between men and women in government jobs
Amid reports that former foreign secretary David Miliband (above, right, in 2010) is being lined up to return to the role, possibly with his brother Ed as Chancellor, one female minister complained that Burnham could not have 'more Milibands than women' in the top posts
But Mrs Badenoch told them to pipe down and get chosen on merit instead of retreating into 'more of the failed identity politics that is holding back our country'
A letter written by the Women's Parliamentary Labour Party and seen by the BBC has called on Mr Burnham to ensure a 50:50 split between men and women in government jobs after he succeeds Sir Keir Starmer.
'We are asking you to demonstrate this change from day one and address the toxicity and misogyny within our own party and government,' it said.
Labour has never had a female leader, while the Conservatives have had three, and Mrs Badenoch urged the government to follow its meritocratic example.
'If you run a meritocracy, then you do not have to worry about jobs for the boys,' she wrote.
'Every woman who is a Conservative MP, every woman who has ever won the leadership, has had to fight to get where she is.
'By contrast, Labour women are demanding guarantees from Burnham. But the truth is he doesn't have to give any guarantees.
'If none of Labour's women are prepared to get their hands dirty and challenge him for the leadership, their demands are toothless.'
'In fact, it's quite revealing that the women's parliamentary Labour Party has written to Burnham asking him to commit himself to at least 50 per cent female ministers.
'This has nothing to do with meritocracy. It is yet more of the failed identity politics that is holding back our country.'
