It’s 108 years since the discovery of a fruit cake in Antarctica. Why did scientists think deeply?

In our impression, Antarctica is covered with heavy ice and snow, which is like a world of ice and snow without people coming. There are many marine creatures in Antarctica, and surprisingly, there is still a big cake in Antarctica for more than 100 years. Antarctica is a huge natural refrigerator. If you put a piece of cake in it, can you still eat it 100 years later?

Who left the cake?

In 2018, an Antarctic expedition team found a small wooden house in Antarctica’s Cape Adele. When the researchers walked into the small wooden house, they found a cake that had been stored for more than 100 years. Researchers speculate that this fruit cake may be left behind by British explorer Robert Scott. He went to the Antarctic in 1910, and it has been 108 years since then. It’s amazing that this cake is completely preserved in the cold Antarctic. Can we eat this cake that has spanned a century?

Is the cake still edible?

Although the temperature in Antarctica is relatively low, it is not fixed. The average temperature in Antarctica is about minus 25 degrees Celsius, which is much lower than the freezing layer temperature of our refrigerator, but it is not fixed. With the global warming situation becoming more and more obvious, Antarctica also broke the 20 degree high temperature this year. That is to say, in the past 100 years, the temperature in Antarctica is not constant. This fruit cake is not in the frozen layer of the refrigerator, and it has been thawed. If the food has been frozen, it means that the frequency of microorganisms has greatly increased, that is to say, the fruit cake has gone bad.

If this fruit cake is not thawed, is it still edible? First of all, we need to understand the ingredients of fruit cake. Will these ingredients change under long-term freezing? Although scientists think that the chemical reaction of the food will not stop at a very low temperature, even if the temperature of the food on the surface is very low.

Especially in the hot summer, the temperature in Antarctica breaks through 20 degrees Celsius. In this case, the frozen cake thaws again, which means it has gone bad. So even though the cake has been frozen in Antarctica for hundreds of years, it is still not the original shape.

After seeing this cake, scientists are also worried that Antarctica’s glaciers have begun to melt rapidly. If this situation can not be alleviated, it will affect the global ecological environment, and human beings will have to pay for what they have done.
