Archaeologists have just discovered the most ancient and intact cheese that has ever been found anywhere in the world, and it was recovered from the Egyptian tomb of Ptahmes, the mayor of Memphis, after being left there 3,200 years ago.
The tomb that holds Ptahmes, who was originally mummified and laid to rest in the 13th century BC, was initially discovered back in 1885. However, intense storms over the years caused the Egyptian mayor's tomb to be completely obscured by sand, and it was only just found again in 2010, as Phys.org report.
Many years after this rediscovery, archaeologists noticed that there were some jars that had been left behind in the tomb. One of these contained a solid white substance with fabric delicately covering the jar, and this has turned out to be the oldest cheese not just in Egypt, but anywhere in the world.
However, it did take quite a bit of work to reach the determination that the white substance found in the Egyptian tomb was actually cheese. To identify the substance, Italian researchers first completely dissolved the contents of the jar, and then took its protein constituents so that they could be put through a process that would purify them.
After this, scientists used mass spectrometry and liquid chromatography to analyze these proteins, and by looking at the peptides made, the shocking discovery that the white substance that was found in the Egyptian tomb was actually solid cheese.
