Is It Illegal To Add Preservatives To Canned Food?

The "National Food Safety Standard for the Use of Food Additives" (GB2760-2014) also clearly stipulates that no preservatives shall be added to canned food.

According to the GB2760 2014 National Food Safety Standard for the Use of Food Additives, canned fruits are not allowed to add any preservatives. If preservatives are found in canned fruits, it is a violation. The high-sugar, anaerobic environment in canned fruit is not suitable for microbial growth, so as long as the sterilization is thorough, no preservatives are required.

The canned meat may contain some anaerobic microorganisms due to the more complex types of microorganisms in the meat. The national standard stipulates that some additives can be used, such as nitric acid streptococcus, sodium nitrite, potassium nitrite, etc. As far as my country's production process is concerned, at present, most factories can only rely on the sterilization process to ensure long-term storage of canned food under suitable conditions without additional preservatives, and canned meat is never allowed to add preservatives.
