1. Strict aseptic operation to prevent microbial contamination; operators should turn off the UV lamp before entering the sterile room.

2. The food aseptic workshop should be equipped with an aseptic operation room and a buffer room. The cleanliness of the aseptic operation room should reach 10,000 grades, the indoor temperature should be kept at 20-24 ℃, and the humidity should be kept at 45-60%. The cleanliness of the ultra-clean bench should reach class 100.

3. The sterile room should be kept clean, and it is strictly forbidden to pile up sundries to prevent pollution. Strictly prevent the pollution of all sterilization equipment and culture medium, and those who have been polluted should stop using.
