5. What Kind of Foods Are not Suitable for Vacuum Packaging?

foods-cannot-be-sealed

Fresh plant seeds, corn kernels, whole grains, and so on are not suitable for storage in vacuum bags. Because the living seeds will carry out respiration, even if the air inside is exhausted, it will also carry out anaerobic respiration by itself.

If the seeds are vacuum-packed, the bag will bulge. A lot of gas will bulge the bag, so the seeds need to be dried before being vacuum-packed.

Fresh-Seeds

Fresh Seeds

Plant rhizomes, ginseng, radish, ginger, and so on are not suitable for storage in vacuum bags. For example, for some pickled vegetables, there may be shredded ginger and minced ginger in the vegetables.

If the cells are still alive if they are not pickled, they will also undergo respiration and will swell.

Ginger-Root

9. What Is the Working Principle of a Food Vacuum Packaging Machine?

Sealing-Process-Table

Sealing Process Table

The main function of the food vacuum packaging machine is to remove oxygen, which is beneficial to prevent the food from spoiling.

The working principle of the food vacuum packaging machine is relatively simple.

Because food spoilage is mainly caused by the activity of microorganisms, and most microorganisms (such as molds and yeasts) require oxygen to survive.

Food-Vacuum-Packaging-Line-Chain

Food Vacuum Packaging Line Chain

Vacuum packaging uses this principle to remove the oxygen in the food in the packaging bag, so that the microorganisms lose the environment for survival.

Experiments have shown that when the oxygen concentration in the packaging bag is less than 1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is lower than 0.5%, most microorganisms will be inhibited and stop multiplying.

Oxygen Content Table

 (Note: Vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and the deterioration and discoloration of food caused by enzymatic reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickled etc.)

In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum oxygenation is to prevent food oxidation.

Because oily foods contain a lot of unsaturated fatty acids. Unsaturated fatty acids are easily oxidized by the action of oxygen, thus making the food taste bad and spoiled.

Carbondioxide-Content-Table

Carbon dioxide Content Table

In addition, oxidation can easily cause the loss of vitamin A and vitamin C. The unstable substances in food coloring are exposed to the action of oxygen, darkening the color.

Therefore, oxygenation can effectively prevent food spoilage.

In addition to the function of oxygenation and quality preservation, vacuum packaging mainly has the functions of anti-pressure, gas resistance, and preservation. This can more effectively keep the original color, aroma, taste, shape and nutritional value of the food for a long time.

In addition, there are many foods that cannot be vacuum-packed, but must be vacuum-inflatable packaged. Such as crunchy and brittle food, and food that is easy to agglomerate and easy to deform and lose oil; food with sharp edges and corners or high hardness that will pierce the packaging bag, etc.

Potato-Chips-Vacuum-Packaging-Machine

After the food is vacuum inflated, the inflation pressure in the packaging bag is stronger than the atmospheric pressure outside the packaging bag. This can effectively prevent the food from being crushed and deformed under pressure, making the appearance of the packaging bag more beautiful.

The vacuum inflatable packaging is filled with a single gas such as nitrogen, carbon dioxide, oxygen, or a mixture of two or three gases after vacuum.

Among them, nitrogen is an inert gas, which plays a filling role to maintain a positive pressure in the bag. In this way, the air outside the packaging bag can be prevented from entering the bag, which has a protective effect on the food.

Nitrogen-Vacuum-Packaging

Nitrogen Vacuum Packaging

Carbon dioxide can be dissolved in various fats or water to form carbonic acid that is less acidic. This carbonic acid can effectively inhibit the activity of microorganisms such as mold and spoilage bacteria.

Oxygen can inhibit the growth and reproduction of anaerobic bacteria, and can maintain the freshness and color of fruits and vegetables. High concentrations of oxygen keep fresh meats bright red.

12. Why Does the Vacuum Packaging Machine Leak Air During Packaging?

Air-Leaking-of-Bad-Sealed-Packaging-Bag

Air Leaking of Bad Sealed Packaging Bag

There are many reasons why the vacuum packaging machine cannot be vacuumed cleanly. The main reasons are: the vacuuming time is too short. The vacuum pump is aging or not properly maintained.

The vacuum studio is not well sealed, and there is air leakage when vacuuming. The power of the vacuum pump is too small and the actual pumping speed ratio does not match, and the vacuum cannot be fully pumped.

The solution is as follows:

You should prolong the vacuuming time.

You should replace the vacuum pump, and pay attention to maintaining and replacing the vacuum pump oil timely.

If the vacuum pump has not been maintained for a long time, you should first clean up the waste oil in the vacuum pump before replacing it.

(Generally, the first maintenance is after the vacuum packaging machine has been working continuously for 300 hours.

After that, the maintenance will be carried out after the vacuum packaging machine has been working continuously for 500 hours.)

Proper-Operation

Proper Operation

 You should check the vacuum chamber for leaks. If there is an air leak, you must replace the sealing strip in time.

If the vacuum pump is too small to achieve the desired vacuum effect, you need to replace it with a higher-power vacuum pump.

After the mechanical equipment is bought and used for a period of time, you must pay attention to its maintenance.

Just like a car, it needs regular maintenance. If maintenance is not in place, no matter how good the equipment is, it cannot be used for a long time.

13. How Long Can Vacuum-packed Food Generally be Stored?

Vacuum-packed food can generally be stored for about 1 to 12 months. The storage time varies depending on factors such as the type of food and the processing before packaging.

Different types of food after vacuum packaging have different storage times at room temperature.

In general, fresh agricultural products or lightly processed meat products can be kept at room temperature for 2 days. But after vacuum packaging, it can be extended to 6 days, and some can be extended to 18 days.

Vacuum-Packed-Fresh-Agricultural

 Dried fruit vacuum-packed food can be stored for a long time, even more than twelve months.

Storage-Time-TableStorage Time Table

Cooked vacuum-packed food will keep for a shorter period of time. Typically, it stays fresh for around 15 days in winter and spring. And in summer and fall, it will only keep for about 4 days to about a week, but preferably needs to be refrigerated.

14. How to Vacuum Pack Food With Liquid?

At present, the most common vacuum packaging of pure liquids on the market is Tetra Fino Aseptic, which is what we see as boxed milk. This is the vacuum packaging of pure liquids.

Tetra-Fino-Aseptic

Tetra Fino Aseptic

 When the food with soup is vacuum packed, you can choose a liquid vacuum packing machine. This machine is provided with a groove. This allows the liquid to sink without spilling during vacuum packaging.

There is a double-chamber concave liquid vacuum packaging machine and a rolling vacuum packaging machine. By adjusting the angle of the machine, a certain angle of inclination can be created to prevent the soup from spilling.

15. Can You Eat the Leaking Vacuum-packed Food?

Vacuum-packed-greens

You would better not eat food that is leaking air.

It is best for you not to eat food that leaks air, because the vacuum packaging is for the purpose of preventing air from entering, preventing oxidation, and preventing corrosion.

If the vacuum packaging leaks, it proves that the air enters, so the items may deteriorate.

Inflatable packaging is generally filled with nitrogen and carbon dioxide, which can protect fragile food and prevent corrosion.

Once air leaks, the food will be oxidized with the air, and it is likely to deteriorate.

If the air leaks for a long time, it is impossible to judge whether the food is edible or not. It is likely to cause symptoms of abdominal pain, bloating, and diarrhea.

Similarly, food that has no air leakage but has expired is also inedible.

16. What Should You Do When Choosing Food Vacuum Packaging Bags?

Food-Vacuum-Packaging-Bags

Food Vacuum Packaging Bags

 The outer packaging of food vacuum packaging bags needs to be marked with text. Label the factory name, factory address, and product name. And the words “for food” should be clearly marked.

Products are accompanied by a product inspection certificate after leaving the factory. This food vacuum packaging bag is relatively safe.

Colored vacuum bags (dark red or black, etc. currently on the market) cannot be used for food packaging. Because these vacuum bags are often made of recycled plastic.

Food-Vacuum-Packaging-Bags(1)

Food Vacuum Packaging Bags

Food vacuum packaging bags are odorless when they leave the factory. Vacuum bags with special odors cannot be used as food vacuum bags.

Try to use food vacuum packaging bags that are not coated or plated.

In the current packaging design, in order to make the packaging bag more beautiful and corrosion-resistant, many manufacturers have used a large number of materials with coating.

This not only brings difficulties to the recovery and reuse of materials after the products are scrapped. And most of the coating material itself is toxic, if you use these food packaging bags, it will bring great harm to your health.
