The degrees at which you store your frozen food are more important than you think. If the temperature is too low, your food may lose its properties, but if it is too high, it may end up rotting.

The refrigerator is the king of household appliances because it always has to be working. Next to it, its twin brother: the freezer. An appliance capable of freezing any food, preventing it from spoiling, to then be defrosted and return to the condition it was in before hibernation.
However, setting the temperature too low can result in food becoming so frozen that it eventually spoils. And setting the temperature too high can cause food to rot.
What foods are you going to freeze?
The ideal temperature for your freezer depends largely on the food you have put inside.
The general idea is that water freezes at 0ºC. But that is not japan whatsapp numberthe reality. Water solidifies at 0ºC, but to freeze fruit, vegetables and meat, it is usually necessary to freeze at -18ºC .
There are many exceptions to these rules. Foods with a high sugar content, such as ice cream, can be kept at around -12°C . But fish must be frozen at -20°C for 24 to 48 hours before consumption to eliminate all traces of the anisakis parasite .
“Water freezes at 0ºC. For food, we need around minus 18ºC.”
If you are going to freeze foods with a high water content (for example, a pineapple), you will not have to lower the temperature below 0ºC. But for most foods you need colder temperatures. Otherwise, you risk the proliferation of bacteria and microorganisms.
Many freezers allow you to set temperatures as low as -24°C . Such cold temperatures can keep your food in good condition for a long time, but the risk is that you're putting too much strain on your appliance . In addition to high energy consumption, your freezer could fail prematurely.
“Temperatures that are too low (below minus 20ºC) can damage the texture, colour or flavour of a food.”
What is the ideal temperature?
Manufacturers have agreed that the best temperature for your freezer is -17ºC . This value provides a margin of error that allows food to be kept frozen without damaging it, while preventing the generation of bacteria.
5 extra tips to take care of your freezer
As a gift, we are giving you a few tips that will help you improve the performance of your freezer, extend its useful life and save energy:
1. Put a thermometer inside: Even if your model has a built-in digital thermometer, you can check that it is working properly by inserting one and always having two sources of information about the temperature.
2. Do not put hot food in: wait until it is at room temperature to avoid increasing energy consumption and spoiling the rest of the food inside.
3. Do not overfill the drawers: this could reduce the performance of your freezer.
4. Open the door as little as necessary: put several things in at once and try to close it as soon as possible to maintain the temperature.
5. Clean it regularly: No one in their right mind stores food in a dirty place.
“The ideal temperature for a freezer is minus 17ºC, although it varies depending on the food to be frozen.”
