Everyone has eaten canned food, and for canned food, the vacuum level is extremely high. Only when the vacuum level reaches the standard can food be stored for a longer time without spoilage. Today, let's take a look at what factors can affect the vacuum level of canned food?

What factors will affect the vacuum level of canned food

The higher the exhaust temperature and time, the higher the vacuum inside the can. The materials inside the can heat up quickly, which can cause the gas and food inside the can to expand and easily exhaust the air inside the can. Over time, the gas inside the food tissue can be fully discharged. However, if the time is too long, it can lead to product overflow, so it is necessary to pay attention to the exhaust time and temperature.

2. It is also affected by the air pressure. The lower the air pressure, the lower the vacuum inside the can, and the air pressure decreases with the increase of altitude. Therefore, the location chosen by the manufacturer is also very important.

3. The acidity of the food inside the can can also affect the vacuum level, which can easily react with metal bottles. This will increase the pressure inside the can and reduce the vacuum level. Therefore, most people now choose glass canned food.

There are many factors that affect the vacuum degree of canned food, and the above information is hoped to be helpful to everyone. This article is provided by the canned food production line manufacturer for reference only.
