Do You Really Need to Set Your Freezer to 0º?
Refrigerator and freezer temperatures can be tricky. Often the first sign that your appliance is malfunctioning is that it doesn’t seem to be cool enough. With many homeowners now focused on saving energy and having a greener home, is it really necessary to set your freezer to 0º? The FDA Stance According to the FDA, refrigerators should be set at or below 40º, while freezers should remain at 0º. Even energy conservation groups and sites adhere to this, with many advocating that while a refrigerator set 10º colder than necessary could be using 25 percent more energy, the appliance should be kept at 35 to 38º. So, with so many legitimate sources promoting the 0º stance, is there still reason to consider otherwise? There have been articles in the media that suggest that it is okay to adjust the temperature of both the refrigerator and freezer while keeping your food safe. In fact, when you look back at studies conducted in the 1940’s, 50’s and 60’s, these temperatures were brought in to maintain food safety in the appliances of those eras. The temperature of 40º was chosen for refrigerators to minimize the potential for bacterial growth. This number continues to be important in the food industry today, even with the flash freezing and newer technologies today. Freezing temperatures are a little more complicated. There is a science behind obtaining the best temperature to slow or stop enzymes while preserving nutrients. Enzymes are responsible for the ripening and eventual rotting of
