1945 In August, in order to urge Japan to surrender as soon as possible, the United States dropped atomic bombs on Hiroshima and Nagasaki, Japan, causing a large number of civilian casualties and building damage. Knowing that Japan could not return to heaven, it announced unconditionally on August 15 of the same year. After the war, the Japanese government built a World War II monument in Hiroshima to commemorate the dead, and an exhibition hall was built next to the monument, displaying many articles about World War II, including a box of unopened Japanese cans. The production time is shown as 1944, after more than half a century. In order to verify whether this batch of canned food is still edible, the Japanese side made a very interesting experiment. The can was heated in hot water, and the inside was found after opening the lid.
What? The military canned food produced by 1944 can still be eaten after more than half a century. This quality is too good.
Military canned food has always been the favorite dry food for countries marching during World War II. Because it is easy to carry and has a long shelf life, it is very popular with soldiers from all over the world. Japan's military canned food production was also influenced by European countries in the early stage, but there is a shortage of meat in Japan, so there are more seafood in military canned food, but it can't provide much energy at all. Even the Japanese soldiers felt sick after eating too much fish, and finally they were not allowed to start importing American canned food. After the Pearl Harbor incident broke out, the United States declared war on Japan, and the channels for Japan to import military canned food were cut off. No, the Japanese can only bite the bullet. In order to grasp the quantity and supply the continuous demand, they are very casual in the collocation of canned food. If all the food can be mixed together, it is a hodgepodge, which tastes bad.
As an island country, Japan is short of domestic materials. We can supply some canned pork and beef first. Even rice with potatoes or peanuts behind it, there are some canned fish. Compared with canned beef that American soldiers often eat, canned Japanese food is really shabby. Therefore, before the end of World War II, Japanese soldiers captured by American troops were often sallow and emaciated, mostly because of malnutrition. However, although the canned food in Japan is not very good, the packaging quality is extremely high, which is proved by the fact that the canned food produced by 1944 can still be eaten after more than half a century.
In fact, canned food production in Japan was very strict during World War II. They use canned food sterilized at high temperature for a long time and isolate it from the outside air through vacuum packaging. Therefore, bacteria cannot be directly produced, and canned food under vacuum can be preserved for such a long time. Sterilized and sealed cans, as long as they are not opened, will not have problems for decades. So is our canned food production today. It can be seen that the Japanese are rigorous, do everything according to the process, and never cut corners. The way they do things seriously deserves praise.
