Turning to the books of history, the war of aggression against China is a history that all Chinese cannot forget, and although it has been nearly a hundred years since then, our hatred of war has not diminished in the slightest. History needs to be remembered, and in times of harsh conditions, food was the guarantee of war. So why did the Military cans of the Japanese Army remain unchanged for more than 70 years?
According to records, the food of Japanese soldiers during World War II was usually canned, one is convenient to carry, and during the war, it is often necessary to change the battlefield, so the carrying of food must be convenient. The second is that canned food can be guaranteed fresh for the longest time, so as to ensure the physical strength of soldiers. The Japanese craftsmanship in making canned food is very good, especially the sealing of the can, so that the food inside the can is completely isolated from the outside air.
Before the war of aggression against China, Japan can be said to have done its homework, and in the past few decades, in addition to preparing a large number of weapons and materials, it has also stockpiled a large amount of canned food for the war. Some time ago, we even dug up a large amount of canned food at the site left by the Japanese army. One of the things that surprised us the most was not the number, but that after a hundred years, the cans had not deteriorated in the slightest, and experts opened the cans to see what was inside. As a result, I thought I would smell the rotten smell of food, but I didn't know that after opening it, it was a box of bright red bean rice, and the smell did not change at all, and the expert quipped: "I really want to eat it." ”
People present actually want to taste the taste of canned food, but looking at the date of production of red bean rice is 1944, calculate the shelf life of the can, the longest will not exceed four years, gave up this idea, but let us admire that after 76 years of canning, if you do not say the date of production, you can see that there is no difference in fresh food, and the Japanese canning process is indeed admirable. But then again, experts say that more than seventy years of canned food has no signs of deterioration, presumably there must be a lot of embalming substances added to it, for the sake of war, regardless of the soldiers' bodies, such a reason is also lamentable. On the other hand, the can is buried in the ground for a long time, and both the storage temperature and storage conditions will slow down the decay rate of the can.
