Ancient Mummy Cheese Discovered in China
cast doubt on: to make people unsure about whether something is true or correct
Scientists have discovered a 3,500-year-old cheese smeared on ancient mummies in China. To their surprise, the researchers discovered it was a type of kefir. This casts doubt on the belief that kefir originated solely in Russia.
The scientists were able to learn about the cheese by studying its DNA. They found that people in ancient China used milk from both cows and goats to make the ancient food. The scientists were able to learn about the evolution of the cheese by comparing its DNA with modern kefir.
The reason behind smearing kefir on the mummies is unclear, but in ancient cultures, food was often buried as offerings for the afterlife. While the exact purpose of the kefir is a mystery, this discovery helps us understand the history of this fermented food.
