Better Food Storage Solution

I eat a lot of prepackaged microwaveable meals. Because of this, when I make an effort to prepare a home-cooked meal, I don’t fool around. The food is filling, plentiful, and, although not always healthy, it is delicious.

Leftovers are typically packed into old margarine containers and stored in the freezer. If the meal was particularly good, I might leave one container in the fridge for use later that week.

Sometimes, however, the leftovers are stored a little too long, either going bad or suffering from freezer burn.

After researching the various methods that could be used to extend the storage life of food products, I picked up a vacuum sealer.


The KitchenBoss vacuum sealer is 15 inches wide, 5.5 inches deep, and 2.9 inches high. This device can seal bags up to 11.8 inches in width.

It is composed of plastic and sheathed in stainless steel. Five top-mounted buttons are used to control this vacuum sealer.

The main unit, a vacuum hose, 20 heavy-duty storage bags, a user guide, a spare gasket, and a cloth storage bag are stored inside the box.

It runs on AC and is rated at 100 watts.

This unit is used to vacuum and seal storage bags. Air can also be sucked from specialized containers by connecting the hose accessory and the vacuum sealer.

Benefits of Vacuum Sealing

This technique removes most of the air from the food-filled bag, delaying the unpleasant chemical reactions triggered by oxygen. Because bacteria and mold cannot grow without oxygen, vacuum sealing severely constrains their development.

Vacuum sealing stops fatty materials from becoming rancid. This technique also helps prevent items stored in a freezer from changing color and delays the onslaught of unpleasant odors and slimy films.

The tightly clinging bags do not allow moisture to evaporate. This results in the preservation of the enclosed food’s juices and flavor.

While most conventionally stored foodstuffs will last one to three days in a refrigerator, vacuum-sealed items will typically survive for at least a week. Vacuum-sealed frozen food can be preserved for an entire year.

Meal or family-sized portions can be individually bagged for storage and require less space in the freezer.

Types of Bags

I recommend you purchase rolls of bags rather than packages of individual freezer bags. Rolls tend to be less expensive, and you can tailor the length of the bag to match the product being packaged. The KitchenBoss G210 can vacuum and seal bags up to 11.8 inches in width.

For the following tests, I utilized KitchenBoss’s own brand of bag rolls. The plastic material is quite heavy and durable. I also appreciate the handy bag cutter, which is built into each box.


Like most people, I have limited counter space. This is reserved for my most often used appliances such as my microwave, toaster, two coffee makers—I continuously drink coffee—and my beloved air fryer.

Happily, the KitchenBoss G210 can be conveniently stored in a cupboard. Simply wait for it to cool, wipe the unit down with a damp rag, cram its electrical cord into the tiny compartment provided, and stuff the vacuum sealer into its cloth bag.

Sealing Test

The first step was to cut out a section of a vacuum bag long enough to store the contents of a can of mixed nuts.

I then hung one end of the bag over the sealer’s vacuum chamber and pushed the top cover down until I heard a distinct click.

I plugged in the device and pressed the Seal Only button. This button flashed blue as a tiny strip of the bag was subjected to heat. Once the sealing process was complete, the Inching button began to flash red.

The final step was to release the device’s lock by pushing the Open button and lifting the top section of the vacuum sealer.

Dry Food Test

I poured the contents of a can of assorted nuts into my newly constructed bag. I then hung one end of the bag over the sealer’s vacuum chamber and pushed the top cover down until I heard a distinct click.

For this test, I selected the Dry VAC button. Both the Dry VAC and Seal Only buttons began to flash blue and red.

In this case, the machine applied maximum suction, quickly pulling almost all the air from the bag. Then it sealed the open end by applying heat.

Moist Food Tests

I constructed a second bag, long enough to hold a small portion of cooked chicken. I then added the sliced chicken and locked the open end of the bag into the vacuum sealer.

The next step was to press the Moist VAC button and wait until the bag was vacuumed and sealed. While most of the air was pulled from the bag, suction pressure appeared to be less than what was used when sealing the bag of nuts. I suspect the difference in suction ensures the softer and moister foods are not damaged during this process.

I tried the same experiment again using freshly cut broccoli. As with the chicken, the broccoli was vacuumed and sealed correctly.

Delicate Food Test

I repeated my test, substituting a couple of handfuls of grapes for the broccoli. Because grapes can be easily crushed, I tapped the Inching button instead of pressing the Moist VAC button. The Inching button directly controls the vacuum, applying suction only when it is depressed.

Using this method, I slowly sucked away enough air to help preserve the fruit without damaging it. Then I depressed the Seal Only button to seal the bag.

Watertight Test

Usually, you would use a vacuumable plastic container to store soup, sucking the air from it with the special air hose provided with the KitchenBoss G210.

However, in this test, I dumped the soup into a bag and fit the open end into the vacuum sealer. I then tapped the inching button, observing as the bag compressed, forcing liquid up toward the device.

Once I’d sealed the bag, I laid it atop the counter for an hour, waiting to see if it would leak. Happily, both sealed ends of the bag proved to be air and watertight.

Overall Impression

This vacuum sealer is well-priced and efficiently vacuums and seals a wide variety of items. Quality control appears to be very good. If you are looking for an effective method of storing food products for long periods, The KitchenBoss G210 should be on your shortlist.
