How to make refrigeration effective

Refrigerators are among the most important pieces of equipment for our kitchen. Nowadays, we are used to advanced and technological devices that make us forget how important the refrigeration process was to keep food safe in the past. However, even though we tend to think that refrigerators’ are automatically able to save our food from the dangers of bacteria, there are some actions that should be taken in order to avoid risks.

Bacteria exist in nature and can be found in the air, water, soil and, obviously, the food we eat. When bacteria find favourable conditions, such as temperature or nutrients in food, they grow quickly, causing even illness in some, more serious cases. Thankfully, refrigerators keep this from happening, fighting the growth of bacteria that could be dangerous for our safety. The range of temperature that favours bacteria’s growth is between 40 and 140 °F, wherein bacteria can even double in number in less than 20 minutes. In order to prevent this from happening, it is important to keep our refrigeration systems not higher than 40 °F.

However, choosing the right kind of refrigerator can bring concrete advantages. In fact, some have internal thermometers that can measure the temperature and help us have a clear idea on how to behave. For industrial production, there are some kinds of refrigerators such as the r449a that are built with advanced functions to make the refrigeration process as smooth as possible, highlighting how important it is to avoid any risk of contamination in food.

Nevertheless, choosing a good device is not enough. First of all, we should always make sure to keep the doors closed after we use the refrigerator, because forgetting to do so could cause issues to the food. Secondly, it is important to remove the packaging of food before putting it in the refrigerator. This will prevent any kind of contamination that could come from microorganisms that are found in cupboards or plastic packaging. In particular, raw meat should always be put in specific bags for refrigeration, since it is highly exposed to contamination. Moreover, one of the main suggestions is to avoid placing hot food in the refrigerator. In fact, heat can cause condensation, which may increase the temperature of the refrigerator and lead to some risks. However, always keep in mind that waiting more than 2 hours before refrigerating food is not a good habit and should be discarded.

The last element to keep in mind in order to prevent food to be contaminated is a good maintenance of the refrigerator. Hygiene is strictly necessary and if you want to have your device clean you need to take care of it on a regular basis, by defrosting it as soon as you notice any layer of ice and by always disinfecting your sponge before using it.
