how to use Vacuum sealers

Food storage and preservation has been in practice for centuries. Today, people are conscious of how much food they waste, and are always on the lookout for time-saving solutions. This has meant that food vacuum sealers have become a very handy appliance in the kitchen. They take in the goodness of fresh food, and suction out the air to preserve it perfectly for a specified amount of time in the freezer, fridge, or cupboard. When you are ready to eat your sealed food, simply take it out and enjoy it as fresh as the day it was put in.

Initially, the vacuum sealer was used by food manufacturers to prolong the lifespan of their product while shipping it to their customers as food was usually transported over long distances. This practice dates all the way back to the 1940s. What a vacuum sealer does is prevent the growth of molds and bacteria, while keeping your food fresh.

The time and cost-saving benefits of a vacuum sealer provide are undeniable. You may even be ready to invest in one yourself. Luckily, we have included some food sealer reviews further on in the article to help you choose a suitable model for your home or kitchen. Before owning one though, you must first learn about the fundamentals to get a better appreciation of the products.

What are Food Vacuum Sealers and How Do They Work?

A vacuum sealer works similarly to a vacuum, but it pulls the air out of containers or bags before sealing them. The oxygen has to be removed from the food’s packaging to prevent the growth of bacteria, mold, and fungi that contribute to the spoilage of food. If air is left in the food’s packaging, the taste, texture, and appearance can be changed.

These machines will protect your food from dehydration and freezer burns. When you vacuum seal your food, you should not leave your food out as vacuum sealing does not prevent all types of bacteria. Some types of bacteria actually thrive best in environments of low oxygen. In order to protect your sealed food, you should have them frozen or refrigerated. Also, you should read up about the types of bacteria your food item is susceptible to before you vacuum seal it, as in some instances, traditional storage methods may be the best choice.

How to Use One

Before using a vacuum sealer, there are a few ways to prevent contamination like cleaning and washing everything before sealing. Of course, this washing technique does not apply to dry food like coffee or flour, but to meats and vegetables. The simplest way to use a food vacuum sealer is to fill the bag or container with your desired material. Once the bag or container is filled, depending on the machine, you may have to fasten it to the top of the sealer or feed it into the machine. Once the item is sealed, it is ready for storage.

Dry Food

Dry food products are a lot easier to store and don’t require much preparation. All you have to do is remove the dry food from its original packaging and place it in the sealer bags or container. From there on, you just have to feed the bag or container through the sealer so that the air can be forced out for its conservation. Even if you use a sealer bag, you should still put the item in another bag such as a Mylar or a freezer bag to create an additional barrier that protects your food.

Meat, Vegetables, and Wet Food

With wet food, some sealers recommend that you begin the freezing process before sealing the food as the sealer tends to extract liquid, which dries it out and can cause a lot of mess. Meats and vegetables should be washed and dried before storage. If you intend to store the items, you should store them as soon as you get them from the store. You should be aware of bones as they can tear the bags. Vegetables should be blanched by placing them in a pot of hot water for about four minutes then place it in ice water. The blanching process is used to kill bacteria.

Sous Vide Cooking and Vacuum Sealers

You may have seen this word thrown around quite a bit when the conversation rolls around to vacuum sealers.

This cooking method has recently become popular and may be the reason why you want to buy a sealer appliance in the first place.

Sous vide, meaning ‘under vacuum’ in French, originated in the 1700s before two French chefs brought it back in the ‘60s. It is used to describe a cooking style wherein food is placed in a vacuum sealed bag, and then cooked slowly and gently in a water bath that is highly temperature controlled by an immersion circulator, or sous vide.

The selling point of this cooking style can be seen in the way the temperature control ensures a consistent, complete cooking job. Another great bonus is that little to no fat is lost during the process of cooking, resulting in tender and soft textured food. Needless to say, it’s very popular for preparing meat.

What are the Pros and Cons of Using a Vacuum Sealer?

Using vacuum sealers over traditional storage has several benefits. One of the major benefits that it provides is that it preserves the shelf life of your food. For instance, in a vacuum sealed environment, dry food such as the coffee can last for a one to two year period. Refrigerated food like a bowl of soup can last for several weeks, and frozen food like beef and poultry can last for up to three years. Another benefit is that it also helps maintain the freshness of your food, so the taste is not something you will have to worry about.

However, while there are benefits to using vacuum sealers, the machine can cost a lot of money depending on its size. Also, you incur an additional cost of having to buy the packaging material. There are also several misconceptions of vacuum sealing. While it provides a good storage mechanism, when thawing food, you still need to maintain proper practices to prevent bacterial growth. Also, if the food was contaminated before sealing the food’s packaging, the contamination is still going to be there when you unseal the package as sealing is not a heating process.
