Vacuum Sealed Foods Shelf Life

 

Vacuum Sealed Food Shelf-Life Chart

 
 
 

Whilst keeping the majority of foods in their original packaging can help with preserving them for as long as possible, there are other methods which can prolong the shelf life even further. One of these methods is vacuum packing, removing all the air from a packaged item can help prevent bacteria from growing.

There are many benefits of vacuum packing outside of preventing the growth of bacteria. Some foods don’t necessarily last longer in vacuum bags such as vacuum-packed coffee beans in the freezer, however, the coffee beans will retain much more of their flavor for longer when kept in a vacuum bag. Vacuum packing can also reduce the size of the item, meaning you have more storage.

Freezing food is a great way to preserve it, however, if not stored properly can lead to your food developing freezer burn. This happens when the water molecules within food migrate to the coldest parts of the freezer, often the sides, and cause food to dehydrate.

 

When freezing cruciferous vegetables it’s important to blanch the food first, as they release a gas which can cause the plastic bag to expand. Not ideal when the purpose of vacuum packing is to remove all the gases.

The refrigerator is also a great place to store vacuum-packed food, it can make food last for weeks rather than days. It also allows you to buy food, such as chicken, in bulk, without the fear of having to eat it all over a few days.

 

Conclusion

Overall, we would strongly recommend vacuum packing as much food as you can in these trying times. Make sure you check if the food has any preparation steps before it can be vacuum sealed, it will also be worth checking if the vacuum seal has stayed shut soon after storing. It’s also important to always check food hasn’t gone bad before cooking if it’s been stored for long periods of time, especially raw meats.
