![]() It is worth noting that food will start freezing once temperatures fall below 32 degrees F. Others own refrigerators that perform this task automatically. Some people lower the temperature gradually over the next 24 hours to prevent freezer burn. If it has a thermostat, you should keep the temperature at 0 degrees F. If your appliance has a freezer at the top, you must program it separately. But if you exceed 40 degrees F, bacteria will multiply. The refrigerator’s contents will remain cold without freezing at this temperature. The optimal temperature is 35 to 38 degrees F. But is there a correct temperature for freezing food? Yes, there is.Īccording to US Food and Drug Administration, you have to keep the temperatures in a refrigerator below 40 degrees F. Others will continue to deteriorate regardless of the temperature.įreezing conditions will reduce the rate of deterioration, but they won’t stop it.Ī freezer cannot preserve your food unless you adjust the temperature to create the appropriate conditions. Some food items will remain viable for months, if not years if you freeze them. Refrigerators and freezers can prevent spoilage either temporarily or indefinitely. Technically speaking, fruits must undergo a chemical reaction to mature and ripen.Īnother source of spoilage is bacteria that attract mold. Choice blames food spoilage on chemical reactions like oxidization. First of all, why do people use freezers? You have to understand the role they play before you can make sense of the different temperature options they offer.įreezers preserve food, preventing spoilage. This question is far more complicated than you realize. If the contents are too cold, raise the temperature.īut when you adjust the temperature, you should wait 24 hours for the appliance to take action. If they are warmer than you would like, lower the temperature. If your temperature setting range from 1 to 7, move the dial to 3. If your temperature settings range from 1 to 9, move the dial to 4. But what is the coldest temperature? Is it 1 or 9? These are the baffling questions this guide will attempt to answer. Do freezers have an ideal temperature? If they do, how do you find it? Most freezers have dials with numbers ranging from 1 to 5 or even 9.
