At Smarssen, we offer two different food vacuum setalers so that you can easily preserve your food. However, not everyone is aware of the powerful benefits that vacuum sealing can offer. Vacuum sealing was first used in the 1940s in an effort to save money during World War II. This allowed people to avoid spoilage and prolong the shelf life of their groceries, particularly when shipping long distances. This method extended the shelf life of food, prevented freezer burn, and helped food taste fresher for longer. These are the reasons why vacuum sealing is still used today. In many households, people use vacuum sealing to preserve, store, and protect their groceries.


How Vacuuming Sealing Food Prevents Spoilage

Vacuum sealing works to preserve food by preventing mold, fungus, and spoilage bacteria from growing. Bacteria such as mesophiles, thermophiles, psychrophiles, and psychrotrophs break down the enzymes in good as they grow and multiply, leaving behind ammonia, amines, and sulfides which cause discoloration, slimy residue, and potent odors. This does not only make your food significantly less appetizing, these spoiled foods are dangerous to eat. However, these types of obligate bacteria require oxygen in order reproduce. When you vacuum seal foods, you prevent oxygen from reaching your foods, which prevents the growth cycle of bacteria, mold, and fungal spores. By depriving them of oxygen, they cannot reproduce and cause your food to spoil.


How Vacuuming Sealing Food Prevents Freezer Burn

You can also vacuum seal your frozen foods to prevent freezer burn. When foods are vacuum sealed, they are kept out of the air, preventing moisture from evaporating inside. Freezer burns happens because water sublimates inside the food. Ice crystals inside your food becomes water vapor and is drawn to the surface of the food and either freezes again or escapes into the air, causing freezer burn. While freezer burn won’t make you ill, it does ruin the texture and taste of food. If you vacuum seal your food, however, you don’t have to worry about freezer burn because it prevents water vaporization. Vacuum-sealed food maintains the taste and texture it had when you sealed it.


How to Store Vacuum-Sealed Food

Vacuum-sealed food should not be stored at room temperature. The seal only prevents obligate bacteria, the type that needs oxygen to grow. Anaerobic bacteria, the type of bacteria that does not need oxygen, is not prevented by vacuum sealing. Some of these strains of bacteria can make you sick if ingested, and if you do not store food properly, they can spread quite quickly. You can prevent anaerobic bacteria from growing on your food by always properly storing your food in the freezer or refrigerator. Your freezer should be set to zero degrees Fahrenheit, as bacteria growth will be completely frozen at this temperature. Your refrigerator should be 41 to 45 degrees Fahrenheit, with meats stored at 41 degrees or below. Dry food should be stored at between 50 and 70 degrees Fahrenheit.


Vacuum Sealing Increases Shelf Life

The shelf life of your food is significantly increased by vacuum sealing. It is estimated that food lasts three to five times longer when vacuum sealed. Keep track of how long your foods have been stored and when you need to eat them by labeling them before storing.

Tips for Sealing Your Food

While vacuum sealing will naturally extend your food’s shelf life, there are steps you can take to even further extend its life. First, thoroughly clean all food before sealing it to prevent contamination. Additionally, if you are working on sealing multiple types of food, make sure you do not cross contaminate by wiping down the counters between each type of food. Your food will last longer if it is not contaminated by other types of food.


Immediately Seal Meat

Once you bring your meat home from the grocery store or farmer's’ market, wash, dry, and seal it. If the meat contains bones that jut out, be careful, as these can tear the bag. Prevent damage by covering any sharp bones with a paper towel before sealing.


Blanch Vegetables

Help your vegetables last longer by blanching them before you seal them. You can do this by placing your vegetable in boiling water for one to four minutes to kill bacteria. Remove it from the pot and place it in ice water to prevent the cooking process, keeping the vegetable from losing the texture. Drain before sealing.


Create a Barrier

Vacuum sealing bags are airtight, but small leaks can occur if food is stored in them for a very long time, which can let oxygen in and spoil the food. Take extra precaution by placing your vacuum sealed foods in a freezer bag to create another barrier to air expose.


Use Oxygen Absorbers

You can also prevent damage to your during leaks by putting oxygen absorbers into the back with your vacuum sealed food. Oxygen absorbers contain iron powder, which traps oxygen by rusting, keeping it from your food. These packets have no effect on the texture or taste of food.
