The refrigerator is a device for storing daily food. However, when using it, we often encounter problems such as sudden power outage or regular power cuts. This can cause the food being stored in the refrigerator, especially in the freezer compartment, to spoil.
In case you return home after a business trip or a long vacation, when the power is back on, everything returns to normal, and the ice in the freezer compartment freezes again like before. It’s hard to tell whether the food in the freezer compartment is still usable or not. These foods may have been contaminated with bacteria or microorganisms that can affect your health.
To find out if the food in the refrigerator is still usable when you are away from home, use the simple trick below:
First, pour water into a cup until it is almost full, then stop. Put the cup of water in the freezer compartment of the refrigerator. Leave the cup of water in the freezer compartment until the water is completely frozen, then take the cup out and place the coin on the surface. Next, place the cup of water with the coin back in the freezer compartment of the refrigerator.
The condition of the coin in the cup of water will reveal the safety of the food, and there are 3 possible scenarios:
When checking, if the coin is still floating on the surface of the cup of water, the refrigerator is still functioning normally, there is no sudden power outage, and the food can be used as usual.
If the coin is suspended in the middle of the cup of water, your refrigerator has experienced a brief power outage and stopped working, but only for a short time. The food may not have been spoiled, but you need to check it thoroughly before using.
If the coin sinks to the bottom of the cup of water, the refrigerator has been off for a long time, causing all the ice in the freezer compartment to melt completely, and that’s why the coin sinks to the bottom. It is highly likely that the food in the refrigerator has been spoiled because it was not stored at a cold enough temperature.
In case you are unsure about the safety or quality of the food, it is best not to use it because health is the most important.
The effect of putting a bowl of water in the refrigerator
At night, put a bowl/cup of water in the freezer compartment and the next morning, transfer the frozen bowl/cup from the freezer compartment to the chilled compartment. Allowing the ice to thaw naturally will provide natural cooling, reducing energy consumption in maintaining the storage temperature. Repeating this process every day will help the refrigerator consume less power.
In addition to saving energy, the process of thawing the ice in the chilled compartment also provides moisture to the food, preventing vegetables and fruits from withering quickly and maintaining their freshness for a longer time.
