unopened ham sausage cannot be eaten after it has expired for half a year.

as we all know, some preservatives are added to ham sausage for storage. When the ham sausage expires, the oil in the ham sausage will be oxidized and decomposed by air, and the preservative in the ham sausage will generate toxic aldehyde peroxide, so it cannot be eaten.

Sausage first originated in Japan, Europe and America, and its history in China is not long. In 1986, at an international food fair, a set of Japanese ham sausage production prototype attracted the strong interest of Gao Fenglai, the representative of Luoyang Meat Joint Factory. It was this set of machinery and equipment that they bought that produced the first ham sausage in China (Chundu Group was the first enterprise to introduce the ligation production line in Chinese history). In 1987, China's first ham sausage was born in Luoyang Chundu. Since then, the central plains has set off a boom in ham sausage sales.
