The world’s oldest cheese has been found in a 3,200 year-old Egyptian tomb.
The cheese was buried alongside Ptahmes – Mayor of the ancient Egyptian capital of Memphis. His final resting place was rediscovered in 2010 after being lost under the desert sand.
The cheese was unable to be eaten as it was contaminated with Brucella melitensis. A bacterium that causes brucellosis, that is common in cows.
One jar contained a solidified whitish mass, as well as canvas fabric that might have covered the jar or been used to preserve its contents.
After dissolving the sample, the researchers purified its protein and analyzed them with liquid chromatography and mass spectrometry.
The tests show the sample was a dairy product made from cow milk and sheep or goat milk.
