What are the benefits of vacuum packaging bags for food?

If the storage period of food is long, it can be produced on a large scale with inventory. Therefore, major food factories are equipped with quick freezing cold storage to store food. If only stored in a cold storage, the storage period and refrigeration quality cannot be improved. The emergence of vacuum packaging bags has brought good news to the storage of food. So, what are the benefits of vacuum packaging bags for food? Next, Jinde Packaging will share with you the function of vacuum packaging bags.

Vacuum packaging bag is a type of packaging in which food is placed in a bag and the gas is released to seal it. Can be used to package meat products, seafood, vegetables and fruits, processed goods, etc. Vacuum packaging bags block gases, alleviate the rate of air oxidation, and achieve the effect of maintaining food quality.

1. Reduce oxidation rate

Just like the body's antioxidant properties for anti-aging, the gradual fusion of ingredients in food with oxygen can also cause oxidation. For example, peeled apples can quickly lose color and become loose at room temperature, resulting in poor taste and reduced nutritional content. Vacuum packaging bags can immediately isolate air and extend the shelf life of food.

2. Inhibit bacterial proliferation

Food can become a breeding ground for bacteria in an oxygen rich environment. The growth of bacteria can accelerate the deterioration of food. Vacuum packaging bags undergo vacuum treatment to create a negative pressure environment inside the bag, which deprives bacteria of living conditions and effectively prolongs the long-term quality of food.

3. Long term preservation

Whether placed at room temperature or in a cold storage, the moisture inside the food gradually evaporates. Once the moisture evaporates, it will cause the appearance to become dry and discolored, and the originally juicy taste will also be greatly reduced. If vacuum packaging bags are used, they can seal the moisture of the food and prevent it from evaporating, effectively preventing it from drying out.

4. Prevent food frostbite

Food stored in cold storage is prone to frostbite due to low temperature or prolonged storage time. Frostbite can cause dehydration, alkalization of vegetable oils, and render food worthless for sale. Vacuum packaging bags can block fluctuations in external temperature and prevent frostbite.

5. The storage period that vacuum packaging bags can increase

Although various foods have different shelf lives depending on their ingredients. And vacuum packaging bags+refrigeration can increase by 2-5 times. The reason why the storage period can be increased by a factor of about depends on the fact that traditional refrigeration methods are prone to frostbite and discoloration, while vacuum packaging bags can avoid such problems.
