Casing packaging has been around 2600 years
Since ancient times, meat has become an important food in the human diet. In order to obtain meat, people sharpened sticks and stones and invented the knife bow. Meat comes from the meat and viscera and other tissues that can be eaten from various animals. With the light and heat of the fire, which is used by human beings, human intelligence has taken an important step in cooked food. Meat is an important part of the hot, cooked food. Boiled, fired, and processed in different ways to become meat of different tastes.
The most important nutritional value of meat food is to provide us with the protein needed for survival and growth. At the same time, it can also supply the body with the required fat and some essential minerals and vitamins. However, it is also because the meat contains various nutrients that can supply almost all living things, including humans, and contains a lot of water, so it is very easy to deteriorate, especially in the hot summer. As long as there is enough air, without proper treatment or preservation of the meat, bacteria will multiply on the surface, and the meat will become sticky, moldy and inedible, even in areas where the air is thin, if not properly protected or treated, meat. It will also become sour and corrupt soon.
Preserving meat in a proper way has become a very important issue, and the packaging of food has come into being.
Packaging for easy storage exchange
With the development of the times, whether the meat is preserved or not has become a key factor in the meat production and processing economy. Packaging is of great significance for the preservation of meat.
Different preservation methods can provide different preservation quality and shelf life. Although freezing is the most important method of preserving fresh meat in recent decades, it is unimaginable to preserve meat by freezing before the invention of mechanical freezing methods such as refrigerators, freezers, and cold storage.
The history of human use of packaging can even be traced back to ancient times. As early as the primitive society of about 10,000 years ago, with the improvement of production technology in the tribe, the production of this unique human ability has been rapidly developed, and people have surplus items that can be used for storage or exchange.
The most primitive packaging method has emerged for storage and exchange needs. Initially, primitive tribes cut off solid rattan to bundle captured animals, or used plant leaves, large shells or hides to wrap various items including food, which is the original The embryonic period of packaging development.
After that, with the improvement of human labor skills, people began to make the most primitive baskets and baskets with plant fibers, etc. Today, calcined stones and mud are used to make clay pots, mud bowls and clay pots. Used to contain and store food, drinks and other items. These inventions have made the purpose of packaging - convenient transportation, storage and storage - improved. It can be said that this is the ancient packaging technology, although the original but it is a great improvement.
Container important packaging material
Around 5,000 BC, it began to enter the Bronze Age.
In the Xia Dynasty more than 4,000 years ago, the Chinese people were able to smelt bronzes. By the time of the Shang and Zhou Dynasties, the smelting technology of bronze was further developed, and the models could be large and beautiful. The wheel of history turned to the Spring and Autumn Period and the Warring States Period. The technology of cast iron steelmaking and paint painting was also mastered. A large number of iron containers and painted wooden containers appeared and became popular.
Looking into the world, in ancient Egypt, around 3000 BC, people on that land began to blow glass containers. Therefore, the history of mankind using ceramics, glass, wood, and metal to process various packaging containers has been for thousands of years. Many of these technologies, such as glass containers and ceramic containers, have been continuously developed and used today.
Packaging from tradition to modern
In 105 AD, China was in the Eastern Han Dynasty, and Cai Lun invented papermaking at this time.
In 610, China's papermaking was transmitted to Japan via Korea, and it was introduced to Zhengzhou in the 13th century. Germany also built the world's first large-scale paper mill.
In the middle of the 11th century, Bi Sheng of the Northern Song Dynasty invented the movable type printing technique. In the 15th century, typography began to appear in Europe, and the packaging, printing and packaging industry began to develop.
In the 16th century, the European ceramic industry began to develop, and the technology was subsequently brought to the Americas. A glass factory was built in the United States and various glass containers were produced. So far, the packaging industry with ceramics, glass, wood, metal and other materials as the main materials has begun to develop rapidly, and modern packaging has begun to transition to modern packaging.
The casing has been used for more than two thousand years.
In the process of tens of thousands of years of human civilization, pickling has been the most important way to preserve meat, and in China, the packaging of meat has a long history. For example, natural casings, as a natural food package that is safe, edible, nutritious and easy to digest, have appeared in China as early as 589 BC and have been used for more than 2,600 years.
The casing is a kind of animal product made by scraping the large and small intestines of livestock. There are pig casings, sheep casings, beef casings, etc. The treated casings are tough and translucent, and the meat can be poured after being processed. Stored in the air for a long time after drying.
