Improper food freezing can lead to bacterial growth.

If you frequently freeze food, you definitely shouldn't miss this article.

Once food has been thawed, you shouldn't refreeze it. Why is this the case? There are two main reasons: the quality of the food is reduced and it relates to our health.

First, refreezing food will cause it to lose its flavor because the water content is frozen. In addition, the cells in the food are broken down during the thawing process, altering its properties. This loss of water reduces nutritional value and changes the taste of food, especially fish.

The second reason relates to the spread of bacteria, some of which have been shown to be very harmful to health. Food nourishes humans and several other organisms, such as bacteria, including Escherichia coli and Salmonella. These remain almost intact even after thawing, only their temperature changes.

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

Furthermore, they can multiply and reproduce very frequently, affecting our health. According to recent studies, bacteria can reproduce in thawed food every two hours. Take a piece of beef as an example. When a piece of beef is thawed, the bacteria will increase exponentially. The situation worsens when you refreeze it, as a large number of bacteria will "hibernate." If that piece of meat is thawed twice, the risk increases every minute. Additionally, you should understand that although they die when cooked, before they die, they have consumed a significant amount of our food and threatened its safety.

The most noticeable health effect of double freezing is that it can damage the intestines, causing diarrhea and sudden abdominal pain. Food should not be thawed twice, even with the help of water, because the cell walls are destroyed, nutrients are often lost, and the food is less tasty and nutritious.

You can defrost foods with high water content using a microwave. Furthermore, be careful to remove food from its packaging when defrosting in the microwave to avoid it exploding. You should only defrost food that you will cook immediately afterward, avoiding defrosting excess food that you won't use and then have to refreeze.

Foods that can be frozen

We should only freeze foods like meat, fish, shrimp, crab, etc., because these foods have a longer shelf life in the refrigerator. For vegetables, you should buy fresh vegetables and cook them immediately. Although vegetables can also be stored in the refrigerator, their shelf life is quite short and their nutritional content will decrease.

Storage temperature

Storage temperature is the most important factor determining whether a frozen product remains good or not. Typically, frozen meat can be stored for 3 months at -18°C. In reality, very few products are stored at the correct temperature because the freezer compartment of a household refrigerator only reaches a cooling level of around -8°C. Therefore, these frozen foods should be used as soon as possible to prevent spoilage due to temperature changes.

Use frozen food as soon as possible.

How to preserve frozen food

Before freezing, we need to wash the food thoroughly, change the bags and wrapping paper, and avoid mixing raw and cooked foods. Food should be stored in airtight containers or resealable plastic bags to preserve flavor and prevent odors from other foods. For foods with liquid, such as fish and meat, they should be tightly wrapped and placed in the bottom compartment separately to prevent liquid from contaminating other foods.

With conventional refrigerators, housewives often face difficulties because food freezes solid, requiring a long time to thaw. Therefore, you should cut food into bite-sized portions before freezing it; this will make the thawing process quicker and easier.

With a regular refrigerator, you should cut food into small pieces, enough for immediate use, before freezing.

One method that makes freezing food easier for homemakers is the soft-freezing refrigerator. Soft-freezing refrigerators offer an advanced soft-freezing solution, making freezing food much easier. Using a new food freezing mechanism, food is frozen but still easy to cut, minimizing nutrient loss. This reduces the "nightmare" of thawing food for hours, making frozen food preservation much simpler.
