I suggest you don't eat high-temperature ham sausage in the future! Ham is divided into high-temperature products and low-temperature products, and the two production processes are different. The high-temperature products are cooked at a high temperature of 120 degrees, which destroys the nutritional structure of meat. A large number of preservatives are added in the breeding process, so the shelf life of high-temperature ham sausage can reach 120 days to 180 days at room temperature. Think about what meat can last so long? The shelf life of low-temperature products in low-temperature freezer is only about 45 days. Therefore, we must pay attention to buying meat products. The shorter the shelf life, the less anticorrosive components are added.
