Freezing food incorrectly causes bacteria to grow.

If you often freeze food, you should definitely not miss this article.

Once food has been thawed, you should not refreeze it. Why is there this theory? There are two main reasons: the loss of quality of the food and the implications for our health.

First, refreezing food will make it lose its taste because the water content in the food has been frozen. In addition, the cells in the food have been broken down during the thawing process and their properties have changed. The loss of water will reduce the nutritional value and change the taste of the food, especially fish.

The second reason is related to the diffusion of bacteria, some of which have been shown to be very harmful to health. Food feeds humans and some other hosts, such as bacteria, such as Escherichia coli and Salmonella. They remain almost intact even when thawed, only their temperature changes.

Once food has been thawed, you should not refreeze it.

Moreover, they can multiply and reproduce very frequently, affecting our health. According to recent studies, bacteria can reproduce in defrosted food every two hours. Take a piece of beef as an example. When a piece of beef is defrosted, bacteria will increase exponentially. The situation will be worse when you refreeze it, a large number of bacteria will "hibernate". If the same piece of meat is defrosted twice, the risk increases by the minute. In addition, you also need to understand that, although they will die when cooked, before they die, they have eaten a lot of our food and threaten the safety of food.

The most obvious health effect of freezing twice is that it can damage the intestines, causing diarrhea and sudden stomachaches. Food should not be thawed twice, even with the help of water, because the cell walls will be destroyed, nutrients will often disappear, making the food less delicious and nutritious.

You can defrost in the microwave, with foods rich in water. Moreover, you must pay attention to take the food out of the bag when defrosting in the microwave or you will explode. You should only defrost the food that you will cook immediately, avoid defrosting excess, not using it all and having to refreeze it.

Foods that can be frozen

We should only freeze foods such as meat, fish, shrimp, crab, etc. because these foods have a long shelf life in the refrigerator. With foods such as vegetables, you should buy fresh vegetables and process them immediately. Although vegetables can also be stored in the refrigerator, however, their shelf life is quite short and their nutritional content will not be as good as before.

Storage temperature

Storage temperature is the most important factor that determines whether the frozen product is still good or not. Normally, frozen meat can be stored for 3 months at -18oC. In reality, very few products are stored at the correct temperature because the freezer of a home refrigerator can only reach a cooling temperature of about -8oC. Therefore, these frozen foods should be used as soon as possible so that the product does not deteriorate under the influence of temperature.

Use frozen food as soon as possible.

How to preserve frozen food

Before freezing, we need to wash the food, change the bag, wrap it with another paper and do not put fresh and raw food together with cooked food. Food should be stored in boxes with lids or zip-lock plastic bags to keep the food's flavor and avoid the smell of other foods. For foods containing water such as fish and meat, we should wrap it tightly in the bottom compartment, separately, to avoid water from flowing into other foods and contaminating them.

With conventional refrigerators, housewives often encounter difficulties because the food is frozen and requires a lot of time to defrost, so you should cut the food into bite-sized portions before freezing the food. This will help the defrosting process to be quicker and easier.

With a regular refrigerator, you should cut food into small pieces before freezing.

There is a method that helps women more easily freeze food, which is a soft freezer. Soft freezers provide an advanced soft freezing solution, thanks to which, freezing food will become easier. Soft freezers use a new generation of food freezing mechanism, food will be guaranteed to be frozen but very easy to cut, limiting the loss of nutrients, helping housewives reduce the "obsession" of having to defrost food for hours, preserving frozen food will become much easier.
