Ancient Cheese Found with Mummies Reveals Historical Fermentation Techniques

In a significant archaeological discovery, scientists have analyzed cheese samples found in the tombs of the Tarim Basin, which are over 3,000 years old. The samples contained DNA from cows and goats, as well as microorganisms such as Lactobacillus kefiranofaciens and Pichia kudriavzevii, which are characteristic of kefir fermentation. These findings confirm that the cheese was produced using kefir grains, a technique that has ancient roots.

The study also contributes to understanding the evolution of microorganisms used in dairy production. The strains identified in the ancient samples show a closer relation to modern Tibetan varieties, suggesting that kefir's history may be more extensive than previously thought, going beyond its traditionally assumed origins in the Caucasus Mountains.

This discovery highlights the historical importance of fermentation as a milk transformation technology. The research shows that processes now considered sophisticated were already mastered by ancient communities, demonstrating a long-standing relationship between humans, microorganisms, and fermented foods.

More than just an archaeological record, the cheese preserved in the Tarim Basin tombs expands the understanding of production techniques, applied microbiology in food, and the cultural significance that dairy products held over three millennia ago.
