Cheese should be well-aged. Some are aged for a month, some for a few weeks, and some for upward of 9 to 12 months. But, most of the time, it doesn't take much longer than that.
It definitely doesn't take 3,200 years.
But that's a team of archeologists found a few years ago while sorting through sand in an ancient tomb in Egypt. The team came across broken jars, one of which was filled with this strange, unknown white substance. Guesses were made, and the substance was sent in for testing.
In a new analysis in the American Chemical Society's Analytical Chemistry the 3,200-year-old substance they found was ancient cheese.
The tomb belonged to a top official and mayor of the ancient city of Memphis, Ptahmes, from the 13th century.
Enrico Greco co-wrote the report for the journal, and serves as a Research Assistant at Peking University in Beijing, China. He explained the first few rounds of testing confirmed the mysterious white stuff was food:
"The archaeologists suspected it was food, according to the conservation method and the position of the finding inside the tomb, but we discovered it was cheese after the first tests."
