Can We Use a Vacuum Seal Machine to Fresh Vegetables?

Homemakers who happen to have a backyard vegetable garden of their own, and even those fresh, crisp veggies we buy from local supermarkets, can we use a vacuum seal machine to preserve their freshness and thus make them last for longer in the fridge?

Wonder no more, the answer to this quintessential question of many housewives and homemakers is yes, you may. However, please note that the amount of work involved here depending upon the food item or the kind of vegetable you want to vacuum seal.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  

For the vast majority of vegetables, vacuum sealing them and having stacked in your freezer would be just fine.  Like for instance, would you believe that green beans, once vacuum sealed, can last for about 3-4 years in the freezer? Under normal conditions, their normal shelf life would be about 8 months. The same thing is also true in corn and other similar crops.  

Cruciferous Vegetables

These plants, cruciferous vegetables, belonging to the cabbage family, will normally require an extra amount of work to be done on them first before you can vacuum seal them. These types of vegetables include:

  • Broccoli
  • Cauliflower
  • Kale
  • Radish
  • Cabbage
  • Brussels sprouts
  • Turnips

This bunch of veggies is indeed savory greens, yet they emit gasses. This means to say that if you will vacuum seal them, the bag itself is likely to get filled up with their emitted gasses and thus would have them get spoiled.  If you want to vacuum seal cruciferous veggies for long term storage, it is paramount that you blanch them first. 

Blanching

What is blanching? This is a process of boiling, say for cruciferous vegetables, for just a very short amount of time and then you will bung them in a bowl of ice cold water.  The cold water will put a stop to the cooking process due to acquired heat from the boiling water, and at the same time will help preserve their freshness as indicated by their crisp, natural greenish color. 

Blanching vegetables will help in deactivating their enzymes that produce unwanted gas. When blanching veggies, it is of vital importance that you monitor the process closely. Otherwise, you will end up cooking it already.  

Can You Use Your Vacuum Seal Machine on a Lettuce? 

You can vacuum seal lettuce, but in order to prevent them from being crushed during the sealing process, it is best that you make use of vacuum canisters instead and not sealing bags. 

You may come across vacuum canisters that are battery operated and these are most ideal for those who do not have their very own vacuum seal machine yet. 

For some homemakers and housewives who happen to have a portable vacuum sealer with a coordinating vacuum sealer canisters, you may want to try out or follow these steps. 

In order to seal, you can add you lettuce to your canister, and then attach the lid. Twist and turn the knob that is on top of the canister until the arrow itself is pointing to “Vacuum”. 

Have the other end of the hose attached to the canister. As for the other end, get it onto the accessory port of your machine. Run the machine as per instructions it came with. After which, turn the canister know towards the “Lock” position, then, finally you can remove the hose.
