The technological development that the world has experienced over the past few decades has extended its waves towards food preservation. It is the human response to combat the phenomenon of full trash bins that are increasingly settling across cities. Thus, like the oven, the refrigerator, or the freezer, a means to extend the shelf life of food has emerged: vacuum preservation. Through this article, we will tell you everything about the operating criteria of this technique.
What are the criteria for vacuum food preservation?
Among the most appropriate means to preserve food, you have opted for vacuum preservation? Well, you will need to master the criteria that come into play to effectively implement this technique. First, you need to acquire a high-performance vacuum machine. Many models are available on the market, so you must be smart in your choice. It should be noted that the selection criteria should focus on the power of the machine (130 watts), the speed of execution, and the durability. Generally, there are two types: external suction machines and chamber vacuum machines.

Both products are equipped with automatic or manual mechanisms that allow for air extraction. To put the process into practice, you need to place the food in packaging and insert it into the machine, which will extract the oxygen. Once the suction process is complete, the vacuum machine seals the packages hermetically to protect your food from microbes and bacteria. However, necessary precautions must be taken for successful preservation:
- Avoid placing hot food in the vacuum machine;
- Use clean and properly sized packaging;
- Properly arrange bones so they do not puncture the packaging.
Vacuum preservation: what are the advantages?
Vacuum machines are known for their versatility. This means they preserve a variety of food products, including meat, vegetables, fruits, flour, coffee, etc. The second aspect of the usefulness of this method lies in its ability to keep food in good condition for a longer period compared to traditional methods. It is the safest system to eliminate waste. Furthermore, this process preserves all the vitamins contained in the food for a significant duration. Additionally, we can add the assurance of rehydrating food that this machine provides. Moreover, while the freezer only puts bacteria to sleep, vacuum preservation kills them. Finally, regardless of how long your food is preserved in vacuum mode, you will find it with the same flavors.
