Freezing fresh mushrooms in a vacuum pack
Fresh/raw/cooked mushrooms can be difficult to preserve due to their water content and fragility. However, there is one technique that really changes the game.
Vacuum-freezing fresh mushrooms is an effective way to extend their shelf life, maintain their freshness, and preserve their nutrients. By using a vacuum-sealing machine and bag, the mushrooms are protected from oxidation and bacteria, allowing for a longer freezer life of 8 to 10 months. This technique is especially useful for fresh mushrooms, which have a high water content and can quickly become mushy and less flavorful when stored outdoors.
In this article, we'll explore the steps involved in vacuum-sealing mushrooms, as well as the pros and cons of this method. We'll also examine different storage options, including refrigeration and freezing, and best practices for ensuring the quality and safety of mushrooms when vacuum-sealing:
Can you vacuum pack fresh mushrooms?
Yes, it is possible to vacuum seal fresh mushrooms. However, it's important to note that mushrooms have a high water content and can become mushy when vacuum sealed. Therefore, it's best to vacuum seal them after sautéing or grilling to reduce the water content. It's also important to ensure the mushrooms are clean and dry before vacuum sealing to prevent bacteria growth.
Storage time for vacuum-packed mushrooms:
Here is an indicative table of the shelf life of vacuum-packed mushrooms depending on the storage temperature:
| Types of mushrooms | Vacuum packed in the refrigerator (4°C) | Vacuum packed in the freezer (-18° to 24°C) |
|---|---|---|
| Fresh mushrooms | 17 to 20 days | 8-10 months |
| Raw mushrooms | 17 to 20 days | 8-10 months |
| Cooked mushrooms | 13 to 15 days | 7-10 months |
Please note that these figures are given as a guide and may vary depending on the quality of the mushrooms before vacuuming and the absence of air in the vacuum bag. Check the vacuum-sealed mushrooms regularly for any signs of mold or damage and discard them if necessary.
We also recommend marking the vacuum packing date on the bag for better traceability.
Vacuum-packed mushroom preservation:
Generally, vacuum-sealed mushrooms can be stored for about 2 to 4 weeks in the refrigerator if the bag is airtight and there are no air leaks. If you freeze vacuum-sealed mushrooms, they can be stored for 7 to 10 months at a temperature between -18° and -24°C.
Be aware that the quality of mushrooms can decline over time, so it's best to consume them as soon as possible after preparing them. It's also important to regularly check the condition of the mushrooms in their bags and discard them if fungus develops inside.
How to vacuum seal mushrooms?
-
Clean/rinse the mushrooms thoroughly, removing any dirt and cutting them into similarly sized pieces.
-
Dry the mushrooms.
-
Place them in a vacuum bag and start sucking out the air with a vacuum machine.
-
Seal the bag with the machine.
- Vacuum-pack the mushrooms in the refrigerator or freezer depending on your storage needs.
It's important to note that vacuum-packed frozen mushrooms can be used in many recipes, but they can become mushy when reheated, so they're best used in recipes where they're incorporated as an ingredient rather than eaten on their own.
