Many people use this bag to pack food, but most are doing the wrong way

The type of bag we are talking about is a zip lock plastic bag. So, so far, have we done wrong?

The locker bag has become an indispensable friend in every kitchen. Why?

Because it is neat, clean and can create a foot environment that does not help your food be preserved longer. Yes, you can't mistake it, it can create a vacuum, just before you closed the bag wrongly.

Oxygen is an essential element for life, and also a "game breaker" that causes food to spoil and rot. Oxygen also creates an ideal living environment for many species of fungi, bacteria, parasites that cause disease in the food.

Therefore, when storing food, people often have to do everything to limit the amount of oxygen as low as possible, and the best way is to use a vacuum machine. However, this machine is not a perfect choice because it is relatively expensive.

The indisputable convenience of lockable bags.

Therefore, this type of lock bag was born as a savior for busy housewives, while helping bad snack bags with crispness, keeping vegetables fresh during the week and cheese. tomorrow to be available for the whole month.

So how can we make the most of this food bag's potential? There are people who try . squeeze and squeeze gas out and then pull the lock. There are people who just ignore it, as long as it is closed. It's all wrong, no matter how hard you try to suppress it, you still leave . all the gas in it.

So how is it true? Sharon Franke, Kitchen Appliances lab manager Good Housekeeping Institute, shared some of the "tricks" used to use this bag in a "no-hassle" way.

First, keep doing everything as usual: open the bag, remove the food, squeeze the air out and close the bag (remember to leave a small hole about 1 finger).

Open the bag, remove the food, squeeze the gas out and close the bag.

Next, put your mouth into that hole and . pull out the air. If you are afraid of losing hygiene, you can use a straw instead.

The bag to be sucked out of the air will "shrink" like this.

In addition, you can also take advantage of water pressure to vacuum food bags.

Specifically, instead of using a straw or mouth to push the air out, put the food bag in a bowl of water, gradually lowering the bag down to near the mouth of the bag. Thanks to the pressure of the water, the air in the bag will be pushed out.

You pay attention not to let the bag of the water get stuck in the water.

After the excess air has been ejected, the internal environment has reached the state of running out of air (you can see with the naked eye), then close the bag completely and store it in the refrigerator.

Of course, since this is a no-cost manual way, it will not create an absolute vacuum environment like in industry. A little air will come in from your mouth or from the hole when you're about to pack. But that is still considered acceptable, because you have eliminated most of the air out.
