Foods That Should Not Be Vacuum Sealed

Foods That Should Not Be Vacuum Sealed

 

Have you ever wondered if there are foods you should not be vacuum sealing? There are many foods you can vacuum seal for extended freshness; unfortunately there are a handful that you should not preserve using this method. Some foods contain anaerobic bacteria, which can grow without the presence of air. Within a vacuum sealed pouch, with reduced oxygen, these bacteria will grow and may pose a risk to your health.

 Do not vacuum seal:

      • raw mushrooms
      • garlic
      • soft cheeses (blue cheese, brie, camembert, ricotta and other soft and unpasteurized cheeses)
      • freshly cooked or steamed vegetables (safe to vacuum seal after they are at room temperature)

           

          In addition, many common vegetables emit a gas when stored. If these vegetables - in the Cruciferae or Brassicaceae family - are kept in a vacuum sealed bag, this gas will cause them to spoil. To store these vegetables properly they should be blanched, dried, then vacuum sealed and frozen for storage.

           Blanch first:

              • arugula
              • bok choy
              • broccoli
              • brussels sprouts
              • cabbage
              • cauliflower
              • kale
              • radishes
              • turnips

               

              We hope this little guide has assisted you in identifying the few items that should not be vacuum sealed. You can use your vacuum sealer to safely store breads, meats, vegetables, potatoes and more. Most foods can be vacuum sealed to extend their overall life whilst saving you some money and time!

                Hi Nancy – We are so happy you love vacuum sealing! Please feel free to share your tips or tricks. We would love to hear them!

                Hi Pearl – Fresh Pasta can be vacuum sealed. If you’re making it, you can store it in the fridge for about a day. If you freeze it, it will last about a month.

              • Nancy All: December 29, 2020

                I have used a food saver since my kids were small. At 71 I am still learning new stuff. I just love it. If I want corn on the cob for Christmas I buy at peek season and vacuum seal.

              • Pearl: December 29, 2020

                Hi can i vacuum fresh pasta and how long will it stay if it’s vacuum sealed? Should i put it in the freezer or just in the fridge? Thank you

                Do these recommendations pertain to foods that are being vacuum sealed and then immediately refrigerated and intended to be consumed within expiration date ? For example, ricotta that is vac sealed and the put in the fridge immediately.

                Hi Gail – We do not recommend vacuum sealing any form of fresh onion. Doing so could lead to the growth of the bacteria botulism, which can be lethal.

              • Gail: December 17, 2020

                can you vac seal whole onions that have not been chopped up but just had the outer skin removed?

              • FoodVacBags: November 05, 2020

                Hi Kerrie! Thanks for the question! Yes! We use FoodVacBags to seal our batch cooked foods and store them in the freezer until we are ready to use them.

              • Kerrie : November 05, 2020

                Hello, I am looking into getting a vacuum sealer for batch cooking. Dishes such as soups, chilli, bolognese, pulled pork etc. Would this be suitable?

              • FoodVacBags: November 02, 2020

                Hi Hope! We do not recommend vacuum sealing freshly chopped onions. Vacuum sealing fresh onions can lead to the growth of botulism. If you cook the onions, you can certainly vacuum seal them once they are cool. Botulism only affects fresh onions.

              • Hope McIver-Wearing: November 02, 2020

                Can you vacuum seal fresh chopped onions?

                Hi Sherri – You absolutely can vacuum seal dehydrated mushrooms and dehydrated cabbage!

              • Sherri: October 16, 2020

                Is it ok to vacuum seal raw dehydrated mushrooms and cabbage? I’ve did some a few months ago and they seem fine, no bags have exploded…so far…

                Hi Gail – if you are planning on storing any meat long term, we do recommend vacuum sealing it and keeping it in the freezer.

              • Gail: September 24, 2020

                I’m confused. I’m new to prepping and have seen conflicting information. Can I dehydrate thoroughly cooked ground beef, chicken and turkey, vacuum seal it, and keep it for long term storage? Do I have to refrigerate or freeze my packages?

              • FoodVacBags: September 21, 2020

                Hi Rhonda – Coleslaw is a tricky one! I’ve done a bit of research. The internet seems to think you can vacuum seal and freeze coleslaw. They say a vinegar-based coleslaw does better than a mayo-based. The mayo-based gets a bit runny. People also seem to say you can keep it frozen for up to 3 months.
                That said, we do not recommend vacuum sealing fresh cabbage because it will emit gases that will make it rot.

                Hello Kylla – You can freeze granola to keep it fresh for longer. You should transfer granola to either an airtight container or a vacuum seal bag. Moisture is an enemy here, so make sure you have a good seal. If your granola has nuts in it, you’ll want to make sure you freeze it. Nuts, which have a high oil content, are susceptible to going rancid. Also, long-term exposure to air makes granola stale. Neither of these things will make your granola bad in a way it would be unsafe to eat, but the flavor will be different.

              • Kylla: September 21, 2020

                I bought 25lbs of a granola cereal. BBD is Oct 2020. I was thinking of freezing it in freezer bags. But I also have a vacuum sealer. Not sure what would be the better shelf life, freezer bags in the freezer, or vacuumed seal on a shelf.

                The cereal contains pumpkin seeds and flax.

              • Rhonda: September 21, 2020

                Hi
                Is it ok to vacuum seal coleslaw ? If so how long will it last. Thankyou

                Hi Jamie – The best place to store nuts is always going to be in the fridge or freezer as opposed to the pantry. Why? Because nuts contain a high amount of unsaturated fat, a delicate type of oil, which makes them highly prone to going rancid. Spoilage is accelerated even more in the presence of light, oxygen, and—you guessed it—heat. Storing nuts (and seeds) in the fridge or freezer limits their exposure to all three of these, and will result in your nuts tasting less bitter and more flavorful vibrant for a longer period of time.
                You can keep a vacuum-sealed bag of shelled or in-shell nuts in the fridge or freezer for two years.
