3,600-Year-Old Cheese Discovered in China’s Tarim Basin
When it comes to cheese, the older it gets, the more intense the flavor—or so we think. But what if we told you that the world’s oldest cheese, dating back over 3,600 years, was recently discovered in China’s Tarim Basin? While we may never know how it tasted, this ancient find has given researchers a unique peek into the dietary and spiritual lives of an early civilization.
The discovery of the world’s oldest cheese in China’s Tarim Basin has fascinated both archaeologists and food historians alike. Unearthed during excavations of the Xiaohe Cemetery, this 3,600-year-old dairy product has survived millennia thanks to the region’s dry desert climate. Unlike modern cheese, which comes in an array of flavors and textures, this ancient cheese offers a rare glimpse into early methods of fermentation. The preservation of this kefir cheese provides researchers with critical insights into the dietary habits of Bronze Age civilizations and their expertise in food preservation.
Buried With Mummies
Unearthed in the Xiaohe Cemetery, the cheese was found wrapped around the necks and chests of mummies from the Bronze Age. What looked like a strange white substance turned out to be kefir cheese, a fermented dairy product made from cow and goat milk. Researchers had initially been puzzled by this ancient, crumbly relic but were able to confirm its identity through DNA analysis.
The dry desert air of the Tarim Basin played a major role in preserving the cheese for millennia, making it one of the rarest food finds ever recorded. Cheese is typically difficult to preserve over long periods, but this discovery shows the power of nature’s refrigeration.
The Science Behind the Preservation
So, how did this cheese manage to stay intact for over three millennia? The answer lies in the fermentation process and the bacteria involved. Kefir grains—composed of yeast and bacteria—were key to preserving the cheese. These grains fermented the cow and goat milk, reducing its lactose content and making it digestible for the largely lactose-intolerant population.
Over time, the arid conditions of the Tarim Basin dried out the cheese, preventing it from decaying. This slow drying process helped preserve not only the cheese’s structure but also the bacteria and yeast strains present in the kefir. For modern scientists, these strains are a treasure trove of information, allowing them to study the evolution of probiotics and ancient fermentation practices.
