Cheese was first prepared 7500 years ago

A new study by Polish scientists published in the December 12 issue of Nature suggests it is possible for the first time that cheese was created from the sixth millennium BC, about 7,500 years ago.

Scientists have analyzed the chemical composition of the rest of 34 ceramic screening devices dating back to 7,500 years, discovered in Poland to see if people at that time used this item. for what. As a result, they discovered a large amount of fat milk remained on the ceramic pieces, more than the amount of milk sticking to the cups and saucepans found in the same excavation area.

Scientists believe that the above ceramic filters are mainly used for the extraction of fat-rich curd from liquid milk (the remaining milk after frozen yogurt) during the making of raw cheese.

"This is a highly convincing argument that the devices are used for cheese processing," said Professor Richard Evershed of the University of Bristol .

He added that the research team was not sure which type of milk was used to make cheese, but found a lot of cattle bones in the excavation area.

Food science and nutrition professor Paul Kindstedt of the University of Vermont, who has worked on cheese research, says the discovery of cheese has marked a major development of humans in the Stone Age and creation. Practical life benefits. This allows them to process milk into energy products, rich in essential proteins and minerals.

At that time, most adults did not use milk sugar (lactose), so they processed cheese (low in lactose) so that everyone could easily absorb the nutrients in milk.
