The trick to lasting freshness: learn to use vacuum bags correctly

Proper use of vacuum bags can help keep food fresh for a long time. Here are some tips:

1. Make sure foods are dry: Before placing foods in a vacuum bag, make sure they are dry. Moist food may result in an incomplete vacuum seal, which reduces freshness.

2. Avoid overfilling: Do not overfill the vacuum bag. Leave some space so that the food can fit perfectly when sealing. Overfilling may result in an incomplete vacuum seal, which may affect the freshness.

3. Pay attention to the sealing: Use a vacuum sealer or manual vacuum pump to seal the bag. Ensure that the seal is completely tight and that no gas enters or escapes the bag.

4. Pay attention to the shape of the food: For hard and sharp food, it should be wrapped in cling film or other material that prevents it from puncturing the bag before placing it in the vacuum bag.

5. Pay attention to temperature when storing: Place food in vacuum-packed bags in the refrigerator or freezer at the proper temperature to extend the freshness period. Different types of food may require different storage temperatures and times.

Proper use of vacuum packaging bags can help extend the shelf life of food and ensure that it is always fresh and delicious.
