Many people are unaware of how long eggs can last in good condition and how to store them properly to ensure their freshness for a longer time. Fresh eggs can last between three to five weeks in the fridge, as long as they are kept at a constant temperature of 4 degrees to prevent spoilage. The duration may vary depending on their freshness at the time of purchase and temperature fluctuations in the appliance. It is advisable to keep eggs in their original cardboard packaging to protect them from bumps and from absorbing odors from other foods.
Eggs have a shell that acts as a natural barrier against bacteria, making them an essential food as they provide all the essential amino acids for the body. However, the shell is porous and is subject to external factors that can affect its duration. Sudden temperature changes can harm the freshness of eggs, as well as a humid environment that promotes the growth of bacteria, or a very dry area that can cause them to dehydrate.
To determine if an egg is fresh, one can use the float test: place the egg in a glass of water and observe its position. If the egg stays at the bottom, it is fresh and can be consumed without issues. If it remains in the middle, it is still safe to consume, but it is advisable to do so soon. If it floats, it is likely spoiled and has lost density. This method is useful to verify the freshness of eggs and ensure their quality before cooking.
In summary, storing eggs in the fridge at a constant temperature, keeping them in their original packaging, and paying attention to external factors such as humidity and temperature are key practices to prolong the freshness of this essential food in the daily diet. Additionally, being aware of simple methods to check the freshness of eggs, such as the float test, helps ensure their safe and healthy consumption.
