In this time of change, countless new things have come into being, but most of the members of these new things are fleeting, and the things that can go through the baptism of the years are always particularly attractive. The two centuries can come from the ancient Europa, across the Atlantic, over the Caucasus mountains, and this unique The delicacy is brought to the world.

 

At the beginning of the nineteenth Century, the world business was flourishing, the sailors who had long lived in the boat were ill with food such as fresh vegetables and fruits, and some were also suffering from a major threat of life. So the French government of Napoleon used a huge bonus of 12000 francs to find a way to store food for a long time. Appel, a Frenchman, found that food sealed in a glass container is not easy to deteriorate if it is properly heated. Therefore, in response to the government's reward, the method of food preservation is specially studied and the gas tight food preservation method has been invented, which successfully solved the food problem of seafarers. And this airtight food preservation method is the prototype of modern canned food.

 

Not long after Apel's glass cans came out, Peter Durant, an Englishman, made tin tins and got a patent in Britain. In early nineteenth Century, canned skills were spread to the United States, and Cannery was shown in Boston and New York. In 1849, American Henry and Evans opened an unprecedented canning factory. In 1862, French biologist Pasteur published a paper showing that the important cause of food decay was the growth and breeding of microorganisms. As a result, Cannery plants adopt steam sterilization techniques to enable canned food to reach the trade aseptic scale. In 1878, the American canner manufacturer Schleffer invented a high-pressure can to make cans under high pressure sterilization, marking the maturity of canning technology. In 1906, the technology of modern canned production was spread to China. After liberation, China's canned industry developed rapidly, forming a fairly large scale industrial production system. By the middle and late 20th century, canned goods had formed a highly developed industrial chain in developed countries and regions such as Europe, America and Japan, and the consumer market was considerable.

 

The method of canned food in China was used by the public three thousand years ago. The earliest agricultural book, Qi Min Yao Shu, has such a record: "First cut the meat of livestock into pieces, participate in salt and wheat flour mix well, and cross, porcelain in the thick mud head." This is different from the ancient canned food, but it is the same with reason. China has started research on soft canned packaging materials since the late 70s. In the early 80s, some Japanese equipment was introduced, and the first batch of Chinese soft canned dishes were produced. In 1983, China's first soft canned sales to Japan, entered the international market, and continued to sell to North America, Europe, Hong Kong and Macao and other places. At this point, canned food has become an important export commodity in China.

 

Canned space-time travel is also a global tour, affecting not only the global way of life, but also related to economic and cultural. And this journey of time and space will continue to move forward and deduce new brilliance.
