Increase short-life supply with vacuum seal jars

As you work to build your short-life food storage, you should begin to consider techniques to help extend the shelf life of your food. The longer it will last, the more you can store. In addition to freezing, dehydrating, canning, smoking, pickling, and storing in a dark, cool place, simply removing the oxygen from food will make it last much longer.


Many are familiar with vacuum bag sealers that allow you to suck the air out and seal it shut. Freezing food this way can extend it’s life up to five times. It also dramatically reduces or eliminates freezer burn. Many aren’t aware of what else their sealers can do though. Many models come with a utility port where you can connect attachments, such as a jar sealer. An inexpensive but powerful addition to your preservation toolkit, vacuum sealing jars should become part of your cooking and food storage routine.

Are you tired of raisins going stale and brown sugar going hard? I am. It won’t be happening at my house anymore. Suck the air out! Vacuum sealing is not a substitute for canning, but it is an effective way to prolong the life of food. Jellies, mustard, spices, nuts, rice, flour, and dried fruits and vegetables are just a few examples of what you can store, prolonging shelf life years and years.

The jar sealer fits on your own BallĀ® and KerrĀ® Mason jars and comes in wide and regular-mouth sizes. I purchased the one by FoodSaver to go with the vacuum sealer I already own. Using the attachment is even easier than sealing bags.

First, wash your jars, lids, and rings in hot, soapy water. I like the wide-mouth jars for this type of storage as they are much easier to get things in and out of and easier to clean. I can actually fit my fist into the jar since I have small hands.

Next, fill the jars. Use a glove so that you don’t leave the moisture and oils from your hands on the food. Leave one inch of space between the food and the top of the jar.

Connect the utility hose to the vacuum sealer and then engage the lock. Now place a lid on top of the jar. Do not attempt to seal with the ring. You can use it later to prevent the lid from getting knocked, but it is not necessary with jar sealing.

Then, connect the other end of the hose to the jar attachment and press the attachment down firmly over the top of the jar. Your vacuum sealer should have a special button for sealing canisters. Once the vacuum stops, pull the hose out of the attachment to release the pressure. You can then remove the attachment from the jar by pulling directly upward. Don’t forget to disengage the lock on the sealer once you are finished.

Once you are done, you will have jars of food ready for the shelves. Open the sealed jars by placing a teaspoon between the edge of the lid and the highest part of the threads on the bottle opening and prying down.

Here, you can see dehydrated tomatoes, cherry tomatoes, peppers, and jalapenos from this summer’s harvest. I store a jar of each item in the kitchen pantry and the rest go in the store room. Remember, this is food that you are eating regularly and rotating. You are only sealing it to prolong it’s shelf-life. Keep your sealer on your counter. Use it every day. There is no danger or harm in resealing your jars again and again.

  1. I have the wide-mouthed version, but of course have quite a few regular mouth jars as well. You *can* buy another attachment for them as well, but my sealer also came with one of the larger seal able jars you can get. What I learned was that you can put the jar with the lid on inside of that, and then if you seal the big jar, it will seal your inner jar just fine.

    And saved me from buying another piece. Maybe I should post up a video explaining the process.

  2. out of jars??

    my grandfather , born in Brooklyn in 1896 used any jar with intact seals, that means he collected and reused (at the time , around the year 1990), peanut butter, (glass then) juice bottles etc. He died 1196 very close to 101 yrs old, (an uncle clamed his birthdate was wrong and he was actually a year older, being the oldest member of family we wonder maybe its true). He had stopped canning around 7 years bfore his death a few years before going into the “home” he was deaf as a tree and I instlled ever larger bells till I told my dad he needed a 14 inch fire gong. He refused to move in with any family so , the Veterans home it was.

    Big brother took all the canned termaters and veggies and used them, no botch, or anything else.

    Gramps had many ball/mason etc, but he also had as many clamato/pickle/fruit juice/beet bottles.
    ALL tomatoes, all for sauce, all perfect. the other stuff was good as well. many were in reclaimed jars/bottles.

  3. for non canning reuse standard bottles wiith steel lids and home made seals they work well. (bandaid like affair) If you revacuum same jar every/ every few days make a metal valved jar lid or two. If the lid seal fails take valve off put on another lid or use rtv rubber make a quick thin bead over th eold one let set, new seal. Get the one for fish tanks. If you can get a truck tire inner tube you can make one piece inner seals.

    these are for vacuumn not heat sealed boiled canning processing.


  4. My family have one of those vacuum-sealer jars however we've never used it much (because we don't make things that need long-term storing very often).

  6. Since they were so simple, I wondered why my efforts over the years were never as good as his. After much thought, I concluded that the secret is not only the ingredients, it is also the procedure.

    1. getting the seal just right is technique once mastered is easy enough. I practiced on a small jar with nothing in it. I found my making was lacking, and then the technique. With homemade seals it is best to push the tape down afterward so as to make sure it keeps. I sealed small relish jars empty, and put them in freezer to see if that would cause them to release. The better the vacuum pump the better the seal. It also makes it easier.

  7. I love my Foodsaver Vacuum Sealer. I use both the bags (mostly for freezer storage) and the mason jar attachments. Did you know they now have..I think it is 1/2 or 1 gallon mason jars. I put my excess flour (after it has spend time in the refrigerator) and sugar in them.
