Why vacuum seal foods?
There are many benefits for vacuum sealing foods:
- Vacuum-sealed perishable foods can last longer in the fridge as it locks in the color and moisture, helping with freshness.
- It helps prevent freezer burn in the freezer by removing the air pockets.
- It’s necessary to vacuum seal bags for effective sous vide cooking.
- It also helps keep shelf stable ingredients last longer.
What bags can I use?
I recommend using high-quality zip-top plastic freezer bags, especially if you’re using it for sous vide cooking. The brand name zip-top bags are more sturdy and will stay sealed during the long cooking process.
Make sure to use a bag that’s large enough to fit the item with some room to spare. Ideally you’ll need at least one inch between the food and the seam of the bag.

Water displacement method vs. vacuum sealer method
Water displacement method is not as effective as the vacuum sealer, but I find the result good enough for everyday home cooking.
If you use this method for storage, you will hardly notice any difference. If you use it for sous vide cooking, you might notice the vegetables can float above the water sometimes. Just place sous vide weight or heavy kitchen items to keep the food fully submerged in the water.
If you’re ready to invest in one vacuum sealer, I recommend this one that’s inexpensive yet effective from Foodsaver.
