Protect from freezer burn

Vacuum sealing foods protect them from freezer burns and dehydration. Freezer burns occur when air comes in contact with water crystals around food. Vacuum sealing helps prevent air from escaping from food.

Freezer burns are not a threat to your health; however, it can ruin the taste and texture of food.

Fresher food for longer

Lack of air exposure allows for long-term protection and safety in the refrigerator or cabinet. Vacuum sealing protects food by stopping the growth of mold, fungus and bacteria.

This is great when buying seasonal items and food that spoils as fast as vegetables, lettuce and meat. It also works for nuts, pasta, crackers, other pantry items that become soft / stale when exposed to oxygen and moisture in the air.

Year-Round Fresheners

Another great use of vacuum sealing is to store seasonal items, such as tomatoes or berries, for winter use. This way you can get items all year round and when they are out of season, they taste amazingly fresh.

Increase Cabinet Space

Whether in the pantry or in the refrigerator and freezer, the place to eat can determine what is at hand. By vacuum sealing items and stacking or stacking them together, it saves space for more food items such as cans and cans.

Improve Taste, Marinating

Another major advantage of vacuum sealing is that it can be used for food and seasoning for extra flavor. Add pickles or spices to chicken, fish, or beef and then vacuum seal for a quick, amazing boost to your cooking experience.

Save Money on Bulk or Family Packs

There is no question that buying food in family packs or in bulk will give you a better value for your dollars. With vacuum sealing parts, you can save your family a lot of money throughout the year.

Shelf Life

Moreover, the shelf life of most of the food items is increased by the vacuum packaging. It always depends on the product, temperature, atmosphere and the barrier properties of the package.

By vacuum packaging you can increase the shelf life of metals also with the help of the adjustable atmospheric temperature.

Sous-vide

The next advantage of vacuum packaging is that it gives a special cooking method called Sous-vide cooking method. In this method the bag sealed the product in the poaches.

The sealing process is manual as the operator has to manually fill each container in the machine and seal the container with the finger, pressing the switch. This sealing process is repeated for each container.

The Double Seaming Process

Once the air is removed from the containers the double seaming process starts:

• Compression

Can body is compressed by the machine in the direction of the seaming head holding the lid.

• First Roller Operation

The first seaming roller interconnects the can body’s projection with the lid’s whorl to form a slack seam.

• Second Roller Operation

The first seaming roller hideaways and therefore the second seaming roller advances and presses the seam from the primary roller operation to supply an enclosed seal

13. Can I Pack Vacuum Seal Zip Lock Bags With Vacuum Packing Machine?

Zip lock bags make it easy to close or open bags. They are useful for short time storage. Zip lock bags seal is not durable for long time storage. A vacuum sealer is recommended allowing the food to stay fresh for a long period of time. The following process should be followed while sealing zip lock bags by a vacuum packing machine

Choosing a Zip lock Bag

Suitable size and quality are required while choosing a zip lock bag. Two bags are required, one small and one large in size for a handheld machine.

Preparing the Zip lock

Zip lock preparation mainly depends on the type of vacuum sealing machine. For automatic machines, just cut off the zip lock part. For semi-automatic machines, poke 1*1 inch hole at each end of both bags.

Sealing

In the sealing process, the zip lock part is cut off from both ends. The two layers are peeled off apart and are placed inside the bag on both ends to support the bag’s seal. In the last step, the bag is placed inside the machine and turn on the machine; the rest of it will do its magic.

14. Are There Any Other Ways To Extend The Lifespan Of Food?

Following are the ways other than vacuum sealing that can increase the shelf life of the food:

Improving Treatment and Handling Procedures

After harvesting fruits and vegetables, post-harvest handling must be ensured to increase its life span e.g treatment with bad water, store in hot places or contaminated boxes. To increase life span their treatment should be done with clean water, handle with care and store in a cool dry place. Its shelf life will automatically increase. For example, apples can be store for up to 8 months in cold storage.

(Cold Storage-Photo credits: Triburg)

Finding Temperature Weaknesses in Cold Chain

Another way to increase the shelf life of the product is by minimizing the depletion of cold chain temperature differences. If the cold chain is compromised the product’s life span will be reduced.

For example, after harvesting four-hour delay in precooling strawberries resulted in almost 50% of the loss. Some methods can be used to observe the temperature of the cold chain throughout the process.

Monitoring Humidity to Identify Improvement Areas

Controlling humidity also increases the shelf life of food. Humidity monitoring avoids moisture loss thus preventing food from spoiling. Refrigeration most of the time’s loss moisture content of food which is not acceptable. Proper monitoring increases the shelf life.

(Monitoring room-Photo credits: Triburg)

Individual Item Coverings

Proper covering of each food item increases the shelf life of the product. Food degrades when it loses its water after oxidation. Individual covering of food items is recommended, avoid plastic coverings as they are not good for the environment.

(Individual Item Covering-Photo credits: Dreamstime)

Absorbent Food Trays and Pads

Absorbent food trays and pads are recommended to increase the shelf life of the food as these trays decrease the product’s respiration rate.

(Absorbent Food Trays and Pads-Photo credits: Ali Express)

Natural Antimicrobials

Use antimicrobials because they help to prevent spoilage and increase shelf life. The customer nowadays demands natural ingredients so it is compulsory to use natural ingredients not chemicals. Use herb, spice or plant extracts as antimicrobials.

15. What Happens If You Use The Wrong Vacuum Back Bag During The Process?

There are a variety of vacuum bags used in the vacuum packing process. They differ in types, thickness and permeability. While choosing a vacuum bag, one must ensure the bag thickness according to the product; otherwise, there is a possibility of being negative effects. The standard vacuum bag thickness is around 3mm which is used for almost most of the products, but some products need more thickness.

1. If the thickness of the bag is not suitable for the product might become not consumable and become sticky to the product.

2. If the bag is of low-quality wrinkles appear on the bag after sealing and the seal will be burnt, it will look like low-quality sealing.

3. If the bag is bigger in size and the product is small it will take more time and electricity to seal the bags and it would look inappropriate.

4. Sometimes choosing the wrong bag results in spoiling food, ripples and low-quality sealing.
