What is Freezer Burn? Understanding Key Refrigerator Terms
Have you heard the term “freezer burn” anytime? Or are you only tracking fridge prices and fridge offers all the time? It is not wrong to do so, especially with the summer upon us and websites like Bajaj Finserv EMI Store hosting catalogues to do your online shopping. However, spare some time to educate yourself on fridge terms too.
Freezer burn is a condition that occurs when a frozen chunk of meat or any other food has been damaged by dehydration and oxidation. It is caused by food not being tightly covered in air-tight packaging.
If you notice greyish-brown leathery spots on frozen food, then you can be sure that the food has suffered a freezer burn. So should you throw such food? No, absolutely not. It is still edible. Just remove the freezer burn spots for the food to taste better.
Fluctuations in freezer temperature in your refrigerator also contribute to food suffering a freezer burn. You may think frost-free is a feature that you should go in for when you buy the best refrigerator.
But the humble manual-defrost freezer will keep frozen food for longer than frost-free fridges. In manual defrost freezers, the temperature usually stays around -18 degrees Celsius while in frost-free ones the temperature fluctuates, leading to drier air.
Freezer burn is not a concept that is familiar to most people. But there are other refrigerator-related terms you may have heard but may not know their exact meaning. Let us look at them now.
Compressor: This part of your refrigerator is its heart. Gas under low pressure is pumped into the compressor which compresses it to a higher pressure leading to a rise in temperature. This gas then moves to the condenser for the next step in the refrigeration cycle.
Condenser: The condenser is a device which is responsible for heat exchange in the refrigerator. What it does is to remove the heat from the gas and condense it into a liquid refrigerant which keeps the inside of your refrigerator cool.
Thermostat: It is a switch which turns the compressor on and off to maintain the desired temperature inside the refrigerator.
Freezer Compartment: This is a small cooled storage area used for preserving and storing food, and making ice cubes. In single door fridges, the freezer is part of the main body, while in double door fridges, it is a separate compartment.
Star Rating: The Government of India’s Bureau of Energy Efficiency (BEE) implements a Star Rating programme in India for refrigerators. Under this, stars are awarded to refrigerator models under each volume category. The maximum number of stars a fridge can have is five. So if you want the best refrigerator, buy a five-star fridge.
Auto Defrost: This is a system that automatically prevents ice buildup in the freezer by heating the back wall for a short period of time to melt any ice that may have formed. The water gets drained and gets collected in a duct at the back.
Manual Defrost: In refrigerators without an auto-defrost feature, ice buildup needs to be melted by manually pressing a switch for defrosting.
Crisper: A crisper is a drawer compartment located inside a refrigerator. It is designed to prolong the freshness of stored produce. The level of humidity in the crisper is different from the rest of the fridge and helps in keeping vegetables and fruits in a condition of optimal freshness.
Bottom freezer: In some models of refrigerators, the freezer compartment is located below the main compartment.
Side-by-Side Refrigerator: This is a type of refrigerator in which the freezer and refrigerator compartments are located next to each other vertically.
Flush Back Design: In this model of refrigerator, the compressor, coils and other hardware don’t protrude from the back of the unit. This kind of design allows the refrigerator to be kept close to the wall so check Finserv Markets online for one such if you have space constraints.
Sliding Shelves: These shelves slide out from the unit allowing easy access to items on the back of the shelf. They can also be removed for easy cleaning.
Spill Proof Glass Shelves: These shelves have raised edges that create a barrier that stops spilt liquids from flowing out. They are made of tempered glass which is not only stronger but safer if it shatters.
The above are only a few of the terms that help us understand what a refrigerator is all about. As the number of models in the market proliferates with new features, more terms are being added to the glossary of terms related to refrigerators –make sure you ask about them just as you demand information on fridge prices and fridge offers.
