China’s commercial sterile food includes all kinds of canned food, sterile filled dairy products and beverages, liquid infant formula food, liquid formula food for special medical use, etc
Commercial sterile is not an absolute sterile state, it allows the existence of trace microorganisms or bacterial spores in food, but these microorganisms or spores in the environment of the product, such as specific temperature, humidity, pH and other conditions, in a dormant state, will not mass reproduction or pathogenic.
Standards for commercial sterility:
The first experimental process was full-line cleaning-pre-sterilization-production of 2300-2400 packages
The second experiment and the first experiment are less than 24 hours, without cleaning, pre-sterilization production of 2400 packages
The third experiment and the second experiment see 1 day, after cleaning, sterilization production of 2400 packets
Requirements for reaching the standard:
1.Request the end of 3 experiments, less than or equal to 2 packages of bad package rate.
- In the sterility test state of 1:1000, cut open the packaging material for the acidity test. For example, the acidity of the mixing is 14 degrees, and the test must also be 14 degrees.
Currently, Yili in China is a 1:5000 test (5 tests, less than or equal to 3 packets)
