In the quest to extend the shelf life of our foods and preserve their freshness, vacuum packaging has become a popular and effective technique. Not only is it used by large industries, but it is also a popular tool in households looking to minimize food waste and save money in the long run.
In this article, we will explore in detail how to vacuum pack correctly and how a vacuum sealer works .
Why vacuum pack?
Before we dive into the precise technique of vacuum packaging, it's crucial to understand why this practice is so effective . When food comes into contact with air, oxidation and decomposition processes occur that affect its flavor, texture and nutritional value. Vacuum packaging eliminates air around food, slowing down these processes and preserving freshness in an amazing way.
How to vacuum pack?
Proper Preparation: Before starting the vacuum sealing process, make sure the food is clean and dry. The presence of moisture can affect the quality of vacuum sealing, so it is essential to completely dry foods before packaging.
Use quality packaging: The choice of packaging containers is essential. Opt for containers specifically designed for vacuum packaging, as they are stronger and have better sealing capacity. Make sure you leave enough space between the food and the edge of the bag to make sealing easier.
Sealing system: Depending on the type of vacuum sealer you have, it is crucial to follow the manufacturer's instructions for proper sealing. Some canners require you to place the edge of the bag in a specific position to achieve an airtight seal.
Remove the air correctly : Once the bag is placed and sealed, the next step is to remove the air. This is done by creating a vacuum inside the bag. Make sure the process is done evenly to ensure efficient sealing.
Final Sealing: After removing the air, the vacuum sealer will seal the bag permanently. This step is crucial to ensure the long-term freshness and durability of your food. Make sure the seal is complete and without leaks.
How does a vacuum sealer work?
Vacuum sealers operate on the basic principle of removing air from the bag containing the food. This process is carried out in several steps:
Creating a vacuum:
The vacuum sealer sucks air from the container, creating a vacuum that surrounds the food. This step is essential to prevent oxidation and decomposition.
Sealed:
After creating a vacuum, the packaging machine hermetically seals the container. This seal prevents air from returning to the container and protects the food from exposure to oxygen.
Pressure control:
Some vacuum sealers allow you to control the pressure during the process. This customizable setting is useful when packaging delicate foods that could warp under excessive pressure.
Secure storage:
Once the vacuum packaging process is complete, the bags can be stored in the freezer, refrigerator or at room temperature, depending on the nature of the food. Vacuum sealing significantly extends the shelf life of food and maintains its freshness.
Some advices
Virtually any type of food can be vacuum packed, both raw and cooked. Vacuum-packaged foods can be stored in the refrigerator or freezer.
