Everything You Need to Know About Vacuum Packaging

0

Vacuum packaging is one way to increase shelf life of any type of food. There are plenty of food vacuum sealers on the market. Each one has its own pros and cons.

Although getting a vacuum sealer means shelling out certain amount of money, it’s well worth it considering the many benefits it can offer you. As long as you obtain the best unit, it will do an excellent job in quickly sealing your food in an airtight plastic bag.

Why Do You Need to Vacuum-Pack Your Food?

Vacuum packaging means removing air around the bag. It, somehow, reduces levels of oxygen in the package. As a result, it impedes the aerobic harmful bacteria form growing and spoiling the food.

Because it has less amount of air, it reduces the risk of spoilage through oxidation, which is a process that can cause apple, banana and other fruits to turn brown.

And as the air is withdrawn, the pressure within the package is reduced. In a way, it lets you maximize the space in your fridge or freezer.

How Vacuum Packaging Works?

First, you’ll need to place the food in a heat-seal bag compatible with your food vacuum sealer. To obtain an effective sealing when you’re using a plastic bag, you fold back the top of it to ensure that the top of the bag, where sealing takes place, is clean.

Bear in mind that food debris can weaken the bond created by the sealer, causing the bag to leak when you freeze it.

Once the food that you want to preserve is in the bag, you’re now ready to place it into the unit’s opening. Some units are fully automatic, which means that there’s no need for you to press several buttons to start the vacuum process. Others, on the other hand, are manually operated. This means that you need to choose which vacuum-sealing option meets your requirements.

For solid foods, reducing the pressure inside the bag to up to 50mbar will surely produce a tightly-sealed pack. Exactly how far you should lower the oxygen in the bag will depend on the type of food you’re going to seal.

Fragile food items, on the other hand, must be taken properly. If you’re going to vacuum-pack several fragile foods on a regular basis, it’s best to purchase a sealer that lets you adjust the speed.

Once the sealing is done, you can take out the bag and store it in your fridge or freezer. Because the plastic bag or container is sealed shut, there’s no way for air to get inside it.

Can You Vacuum-Seal Other Items, Besides Food?

Yes, you can. This type of kitchen appliance is a versatile machine that can virtually vacuum-seal anything.

For instance, if you’re into water sports, you’re more likely to bring some of your possessions, which can have a high risk of getting them wet. Although you can always use waterproof containers, they won’t effectively protect your items from moisture. Through a vacuum sealer, water can’t permeate the pack. In that way, it won’t ruin whatever is in the bag.

And when you place your touchscreen phone in a vacuum-sealed bag, you can still text or call while you’re in the water.

Avoid Food Waste

Vacuum packaging your food is your best bet to extend the shelf life of your food, as well as its freshness. Food spoils because of bacteria. Although some bacteria are good for you, others can cause your food to spoil or rot. But by moving air and moisture from the bag with food, you prevent spoilage and rotting. Without air, aerobic bacteria, which can alter the food’s safety, can’t thrive, giving you safe and fresh food each time you take it out from the vacuum-sealed bag.
