How Long Does Food Last In A Vacuum Sealed Bag? Food lasts longer when properly packaged. The vacuum sealing process involves removing all the air from the bags before sealing them, which would extend their shelf life by several days. In fact, vacuum-sealed food can last for decades without any loss in flavor or texture. But how do you know how long food will last in the refrigerator and freezer? This is where vacuum-sealed bags come into play!
How Long Does Food Last In A Vacuum Sealed Bag?
1. What is a vacuum-sealed bag?
A Vacuum Sealed Bag is a type of packaging usually used to store food. These bags are used to remove the air inside the bag. This reduces the space inside the bag and increases the shelf life of the food as well as the freshness of the food. The air inside the bag is also replaced with a gas.
How Long Does Food Last In A Vacuum Sealed Bag? Vacuum sealing is not new. Food has been sealed since ancient times, but with its advent came pitfalls. Thomas Jefferson claimed that putting meat in a bottle would “upset the equilibrium of nature; and lead to its extinction.” In 1863 Alexander Bain used physical principles to seal foods to keep them fresh longer, and called it the Bain Vernon system. In 1889, Louis Pasteur applied physical principles to seal foods and closely followed Bain’s methods. His target was drying meat before use in cold storage. In the early 1900s, a general consensus existed that foods should be frozen and vacuum sealed to extend their shelf life.

In the 1960s the first industry-wide sealer, named DCI or Double-C Seal, was developed by Patrón. Since then, the industry has heavily exploited vacuum sealing technologies to maximize freshness.
Once foods are vacuum sealed, it takes about six days for them to lose salt, fat, and water, but other flavors and nutrients remain in the food until it’s time to eat. The time it takes to reach that stage varies depending on how fresh the food is, how it’s packaged, and the temperature of its surroundings. So fresh produce that was picked coincidentally at the grocery store could take 30 days to reach this stage. Because vacuum-sealed foods travel so quickly through the existing transportation system, there are much shorter periods of time for companies like Metro-Goldwyn-Mayer Studios Inc. to ship them to theaters, to grocery stores, and to meal kit services, where manufacturers assemble meals that could be eaten 15 to 30 minutes from the time they’re picked.
2. How does vacuum sealing work?
Vacuum sealing works by removing the air from a plastic bag. After you have filled the plastic bag, you use a special vacuum sealer machine to suck the air out of the bag. The air is pushed out of the bag by creating a negative pressure inside the bag.The counter-current creates a vacuum that seals the bag shut and prevents mold from spores from growing on the food inside. At room temperature, vacuum sealed food typically has a shelf life of 6 to 8 months.
Why is it so important to seal food properly? Because if food gets damaged or adulterated when it’s out in the air, you can end up with food poisoning! Storing food properly prevents contamination and prolongs its shelf life. Let’s talk about the ways this is done.
Food racks are used to prevent contamination in the kitchen. Food handlers place food items on them to prevent cross-contamination. One way food is protected from contamination is through the use of airtight food containment containers — vacuum sealed bags. To provide proper air seal, food handlers put the vacuum sealed bags inside food storage racks.

Food gloves are a necessity when handling food. Food should be handled with the same mindset as you would handle a pet. Food handlers wear gloves when handling raw meat, seafood, and produce.
Another common technique when storing food at home is on trays, bowls, and plate bosses. According to Food Safety News, “pans, flatware, and even dinner plates all can be used as airtight vessels without requiring extra protection.” Food handlers seal the trays, cutlery, and plates with vacuum sealed bags before storing them in a cool, dry place.
According to Encyclopedia Britannica, “Vacuuming (chewing) food is one method used to protect food against contamination… drier air is forced through the food, resulting in the collection of dirt, protein bits, fibers, and other bits of food (protozoans) that could cause food poisoning.” Unfortunately, wet food can contain bacteria.
3. Which foods can be placed in this bag?
The food pyramid is a guide for healthy eating. The bottom of the food pyramid should contain grains, as well as vegetables. The next layer should consist of fruit. The next layer should have dairy products. The top layer should be reserved for fats.
No one would argue that vegetables have much nutritional value. However, fruits contain twice as many nutrients as vegetables, which makes fruits an even better meal choice on their own. Fruits also provide much more vitamin C and vitamin E, which are two vitamins that scientists have linked to healthier heart health. However, less healthy than vegetables are grains, and include foods high in saturated fat, salt, and sugar. Grains include pastas, breads, cereals, and various pasty foods. They’re typically high in sodium and dietary fiber, but little else.
Preservatives are added to every dried product such as dried fruits. They’re considered a safety feature to ensure the safety of dried product. However, despite sanitizing with a bleach solution or using food handling & storage liquids such as bleach, foodborne bacteria such as listeria, norovirus, e. coli, and salmonella can survive for long periods of time in dry foods.
You’ve probably seen the Food Safety & Inspection Service (FSIS) website and realized they have food safety officers with varying degrees of authority over common store foods like canned goods, frozen products, and canned food items. The FSIS officers specifically look for signs such as mold growing on canned foods, and if there are any open refrigerators or freezers.
The bottom line is that if you’re not sure which foods to purchase, follow food safety officers’ lead and buy only at-risk products such as fruits and vegetables.
4. How long will foods last after being placed in a vacuum sealed bag?
A vacuum sealed bag removes all of the oxygen in the bag to prevent spoilage. Once the bag is sealed, the food can survive for many months at room temperature.Food can last as long as five to eight years if properly sealed and stored in a dry, cool place. The area in which the food is stored (fridge or freezer) also needs to be dry and cool, otherwise the food could begin to deteriorate before you’re done using it.
I used to hate vacuum sealing because my food always ended up in an indistinguishable pile of crumbs, granola, and cereal made out of what looked like powdered sugar. At a store, they sell vacuum sealed bags with a “handling” system to help you get the food out of the bag before it breaks up and gives off cloud-like sugar particles.
In India, it is common for restaurants to pack their meals with food which is vacuum sealed and stored in airtight tins known as hawker packs. Traditionally, the food is kept in the tins for between two to three weeks at room temperature, so air can get to the food fast enough for its best quality.
The ones placed in restaurants are most likely to be Indian lassi, mango lassi, and roti wraps or dosas. It is common to consume at least one serving of food a day in India, and most meals are served in a big pan or served on a tray. Without the airtight seal of the packaging to prevent food from absorbing odors and becoming contaminated, you can develop an infinite number of food poisoning germs by simply storing the food in the tin for days on end!
The food storage industry is worth $24 billion and employs over 360,000 Americans.
5. Where can you buy food that has been stored in vacuum-sealed bags?
I have been using vacuum sealed bags for years to store my food in. It’s great because it keeps food fresher for longer while at the same time reducing the amount of time that you need to spend cleaning the fridge.I never like to see food go bad for no reason at all so I always take it to the fridge to check on it regularly. With vacuum sealing bags, you don’t have to do this as often or as often as you would with individual packages of food. The first sign that a food item has gone bad is the smell. Adding a vacuum sealer bag to the mix means that this smell won’t linger for as long and the items that do go bad will be safer than if you simply throw them in the drawer.
For example, when foods begin to go bad, it could mean that the air has been squeezed out of them or that the oxygen has been released from the food during the cooking process. In either scenario, this will result in fruity smells and eventually the strong smell of mold and even mildew. Just because that whiff of mold will last for only a short amount of time, it doesn’t mean the food is bad, it could just be spoiled. Adding a vacuum sealer bag will ensure that this won’t happen.
Now you aren’t going to actually use this bag for storing food. Instead, you will put it on top of your food to seal it and prevent any air from escaping. After this step, your food should last for longer and be safer when reaching new shelves.
Why would you ever want to throw out perfectly good food just because it went bad? It’s sad how easily we do this and yet, we work harder than ever to ensure our food doesn’t go bad. And all of this, you can do at home without having to have a costlier way of storing food.
