Have you been wondering if you can vacuum seal fresh veggies from your garden or the local supermarket? Wonder no more: the answer is yes, although the work involved varies. Many vegetables will do just fine when vacuum sealed and stored in the freezer. Green beans, for instance, can last as long as 2-3 years when vacuum sealed and stored in a freezer, versus a normal safe storage life of 8 months. Corn has a similar life when vacuum sealed.
Some vegetables will require a little extra work before they can be vacuum sealed. These include:
- Brussels sprouts
This group of savory greens emit gasses. If you were to throw them into a vacuum sealer bag and seal them, the bag would fill up with that gas, causing them to spoil. To vacuum seal cruciferous vegetables for long term storage, you should first blanch them.
Blanching vegetables is a process of boiling them for a short period of time and then dropping them in cold water. Boiling deactivates the enzymes responsible for producing the unwanted gas, and the cold water stops the vegetable from cooking. As you might have guessed, the amount of time the vegetable spends in the boiling water will have to be monitored closely, otherwise you could end up cooking it. A few examples, shown below, are given by the National Center for Home Food Preservation.
|Vegetable||Boiling time in minutes|
|Broccoli flowerets 1-1/2" across||3|
|Medium brussels sprouts||4|
|Cauliflower flowerets, 1" across||3|
