Can cold skin vacuum packaging be broken

let’s just put it a little longer, because the vacuum bag outside just sucks out the air, but the fungus will go bad if it exists for a long time

the shelf life of cold skin after vacuum packaging is 7 days at room temperature
1. The shelf life of cold skin after vacuum packaging is 7 days under normal temperature, 15 days under refrigeration and 30 days under freezing
2. After the cool skin cools down naturally, use the household vacuum packaging machine to draw out the air, and then put the oil and pepper together, and the water mixed with salt, monosodium glutamate and vinegar together. Seal it with the fresh-keeping box commonly used in the family. After sealing, sterilization must be carried out again
3. Bacteria will be brought into the packaging, and there are bacteria in the packaging bag, so it needs to be sterilized again after sealing
4. If the sterilization work is not done well, you can see that the cold skin around the gluten begins to turn white overnight. After 36 hours, the bag begins to bulge, and the cold skin turns sour and then breaks down
5. The cold skin is sterilized after being steamed at high temperature. Pay attention to the following treatment: pay attention to the microbial pollution of the air environment when cooling, and pay attention to the microbial pollution of the plate containing the cold skin when cooling; Whether the oil contains bacteria, and whether the bacteria in the hand pollute the cold skin when applying oil; Whether the sliced knife or tool will pollute the cold skin; Whether the packing box contains bacteria. From these four aspects to control microbial pollution, there is no problem.
