Can you vacuum seal asparagus?

Asparagus is a delicious and nutrient-dense vegetable, but it can be difficult to store due to its high water content and short shelf life.

Now discover all our tips for cooking and storing asparagus under vacuum:
Freezing vacuum-packed asparagus?
Yes, it is possible to freeze vacuum-packed asparagus. This preserves the freshness and flavor of the asparagus, as well as extending its shelf life. The asparagus must be dry, and it is recommended to pack them individually or in small groups to prevent them from sticking together.
Vacuum-packed asparagus preservation:
Once packaged, vacuum-sealed asparagus should be stored in a cool, dry place, such as a refrigerator or freezer. It is important to maintain proper temperatures to prevent the growth of harmful bacteria.
Here is a reference table for preserving asparagus under vacuum:
Type of conservation | Retention period | Temperature |
---|---|---|
Refrigeration | 3-5 days | Between 0 and 4 degrees Celsius |
Freezing | 6-8 months | Between -18 and -20 degrees Celsius |
Vacuum-sealed asparagus can be stored in a refrigerator for about 3 to 5 days. In a freezer, it can be stored for several months. It is important to regularly check the vacuum-sealed packaging to ensure there are no air leaks or signs of deterioration.
It's important to note that shelf life can vary depending on the quality of the asparagus and the quality of the vacuum packaging. It's also important to maintain proper storage temperatures to prevent the growth of harmful bacteria and to check the vacuum packaging daily for air leaks or signs of spoilage.

-
Immerse the bags in a water bath at a temperature of 63°C for approximately 60 minutes to eliminate any risk of contamination by pathogenic bacteria.
-
Remove the asparagus from the bain-marie and cool it quickly in ice water.
-
Store vacuum-sealed asparagus in a refrigerator or freezer until ready to use.
