Will vacuum help extend product life?

More recently, it seemed that the vacuum packaging of products was a purely specialized procedure, and it is impossible to do this at home. But technology does not stand still, and now no one will be surprised by portable vacuum packers, which are designed to facilitate and optimize the storage of food at home.

Security

Is it safe to store food and workpieces in a vacuum package? There are no definite answers to this question. Vacuum definitely inhibits the oxidation of many foods, which allows them to stay fresh and healthy longer. However, it is only able to stop the reproduction of microorganisms, including mold and fungi that need air. But there are a huge number of bacteria that do not need air at all. And they will calmly breed even after pumping out air. Not to mention that not many packers are able to completely remove air from a bag or container.

What makes sense to vacuum

Ready-made products are best stored in vacuum packaging:

1. Smoked sausages (up to a year in the refrigerator).
2. Smoked and cured meats (more than 6 months in the refrigerator).
3. Hard cheese (up to 50 days in the refrigerator).
4. Cookies (up to 200-300 days).
5. Coffee (up to a year at room temperature).
6. Tea (up to a year at room temperature).
7. Nuts (100-150 days at room temperature).

You can not worry about these products: without air they will only feel better, and the growth of bacteria in them is minimal.

Do not pack without air

The same cannot be said for fresh foods that are most vulnerable to the anaerobic type of bacteria. It makes no sense to vacuum:

• any types of fresh meat (up to 6 days in the refrigerator);
• milk and dairy products (10-15 days in the refrigerator);
• cheese (hard - up to 50 days, soft - up to 15 days in the refrigerator).

Vacuum packaging extends their shelf life slightly. The likelihood that the products will deteriorate and become dangerous remains high, since the anaerobic bacteria contained in them and not only do not stop multiplying, but also consider the vacuum conditions to be the most favorable.

There are also types of products that should not be placed in a vacuum at all. For example, citrus fruits. As scientific studies show, it is more beneficial for such fruits to stay in contact with air, and they deteriorate rather slowly in the refrigerator.

Vacuum benefits

It should be noted that the use of vacuum packers before freezing can significantly extend the shelf life of many products, from 12 to 36 months. But it is worth remembering that with such heat treatment, one way or another, the structure of the products is damaged. Although much less than without a vacuum.

Vacuum packaging has one more definite advantage - it is convenient to take it with you, and the food inside will be stored for a long time even at room temperature. If you harvest it in a day, then even anaerobic bacteria will not have time to breed, and the food will remain completely safe. It can be safely thrown into a bag and removed during the day.

Resource purityis.decorexpro.com/en/ recommends purchasing a vacuum packaging machine exclusively for harvesting freezing and to provide yourself and your loved ones with food on the go. In all other cases, it cannot be argued that the products will be healthier and safer in a vacuum. And the advertised savings may not be relevant at all, if you remember that you constantly have to buy supplies. Here, everyone decides for himself.
