Preserve Flavor and Quality: How to Choose the Ideal Vacuum Food Container
The three most basic properties are derived from the title:
- The material of the vacuum container must not be harmful to health, i.e. it must be food-friendly
- Compared to the storage environment, it must be able to withstand the pressure difference
- It must be hermetically sealed and able to maintain the created vacuum for a longer
Other aspects to consider:
- technical
- aesthetic
- economic, i.e. the price issue, the initial cost.
Dimensions of the vacuum vessel
Although secondary, remember that getting them in different sizes and designs is essential for practical reasons.
Here, it is not only necessary to think that we do not want to store the jam, spices and spices in small 5-litre containers and pickled cucumbers, not 0.3-litre containers.
Also, how well we can use the available space on the shelves, in the fridge or freezer.
This is made easier if the height and width dimensions are varied, and in terms of shape, we can find both angular and cylindrical shapes because we can cover the corners with a square shape to save space.
It also happens that our storage space is not square-based, in which case the curved shape is advantageous.
Transparency
It is valuable and desirable if the food container is transparent, as this way, you can see the food stored in it.
But possible deterioration and mould can also be easily observed and checked even without resolution.
We note that this is important even if our vacuum container closes perfectly because deterioration is not only caused by the lack of this.
Subscribability
This is where labelling is desired, preferably on the sides and top. In addition to transparency, this is very important if the containers are stacked on each other or the freezer can only be seen from above.
Open, if they can be stacked at all.
Opening and closing the vacuum container
Simple opening and closing and fast vacuuming and venting are also critical.
There are some solutions, such as vacuum jars with an electric vacuum packaging machine, but consider the hassle of taking it out, connecting it, and putting it away every time.
Another solution is using vacuumed glass lids that can only be opened with a unique tool, often with the risk of accidents if the tool is misplaced or lost.
Therefore, it is important to have a user-friendly mechanism for opening and closing the vacuum container that doesn't require additional tools or complex procedures.
The process should be quick and effortless to ensure convenience and encourage frequent use.
Sealing and durability
For effective vacuum sealing, the container must have a reliable sealing mechanism.
The lid or closure should create an airtight seal when the vacuum is applied, preventing air from entering and maintaining the vacuum for an extended period.
It is crucial to ensure that the materials used in the construction of the container are durable and long-lasting.
The container should be resistant to wear and tear, able to withstand temperature variations, and resistant to impact or pressure changes.
Storage convenience
Storage convenience is an essential factor to consider in vacuum containers.
Containers should be stackable, allowing for efficient use of space in the refrigerator, freezer, or pantry.
Additionally, containers with varying sizes and shapes, such as angular and cylindrical designs, can help optimize space utilization and fit different storage areas.
Materials and safety
The choice of materials used in the construction of vacuum containers is crucial for food safety.
Containers should be made from food-grade materials that do not pose any health risks or interact with the stored food.
It is important to ensure that the materials used are free from harmful chemicals and BPA (bisphenol A) to maintain the integrity and safety of the stored food.
