The quest for the ideal temperature

Let’s face it, keeping your food fresh is the reason why you own a refrigerator in the first place. Both your refrigerator and freezer compartments have ideal conditions that slow the development of bacteria and ensures your food is preserved properly but knowing the right temperature is vital to keeping everything fresh. It can also be a good way to save on your electricity bill.


If you want to get the most out of your food storage, we’ve got some helpful tips on how to best manage your refrigerator temperature, just keep reading.


Freezer first:

Health Canada recommends your freezer temperature to be set at -18 degrees Celsius. According to their website, this is the temperature where the metabolic rate of spoilage is the lowest while allowing you to maintain the food’s nutrient level.

Air is the enemy of your frozen food as it can cause frost to form, so to eliminate it, make sure to use airtight containers or a vacuum sealer. Dating your food is also a great idea since some of it will go bad after a certain time, even if kept frozen.


And now the complicated fridge

Once again according to Health Canada, 4 degrees Celsius is the ideal temperature for your refrigerator. Because of the frequent door openings, most refrigerator will keep the interior temperature between 3 and 5 degrees Celsius, which is in accordance with the guidelines. While it’s easy to think only temperature has an impact on how well your food is preserved, there are a number of different factors that can affect it.


As in real life, physics plays a role in how the air moves in your refrigerator. Hot air tends to rise and cold air tends to drop. While manufacturers are working hard to counter that effect, there still can be a slight temperature difference (about 1 degree) between the bottom and top shelf of your refrigerator.


Knowing this will allow you to place your food strategically to ensure maximum freshness:

Vegetables and produce should go in the bottom drawers

Meat and fresh fish should be on the bottom shelf

Dairy products and deli meats should be somewhere in the middle

All meals that have been cooked should be on the top shelf

In order to allow for even more control, a good refrigerator should also have compartments and drawers that allow for a better humidity control to keep a narrower temperature band.


Household thermometers for appliances are VERY unreliable, that’s why a lot of new appliances have a digital display for that allows you a quick look at the temperature inside. Investing in a high-quality refrigerator is the best way to ensure long lasting freshness.


Keep it full, but not too full


Overloading a refrigerator can have a negative impact on the airflow inside the appliance. Depending on how items are placed, you risk the chance of creating “air pockets” that can lead to warmer or colder spots in the refrigerator which could in turn accelerate food spoilage. Although there is no specific rule on the matter, you should avoid overloading your refrigerator. An overstocked fridge can impede the free circulation of air, which can lead to both warm and cold pockets in the refrigerator that can speed up spoilage.


The opposite is also true, an empty refrigerator will cost you more to operate. Once again, physics comes into play and the more items you have in the refrigerator, the more each of these items help lower the overall temperature inside, leading to a more energy efficient appliance.

Save food, save energy, save money

An older refrigerator can be the cause of food spoilage. Today’s refrigerator has become a marvel of technology and design, all in order to save you money. Whether it’s by better controlling the airflow or giving you more control over the temperature, they are also more energy efficient. This efficiency is not only better for the environment but it’s also better for your wallet. Some research has shown older refrigerators to represent up to 25% of a household electricity bill.


Each refrigerator has its own specifications, particularly in regard to energy consumption. It’s important to consult the specifications label to avoid unpleasant surprises. We agree that some labels are hard to understand, that’s why Creative Appliance is always here to help.
