Where to Properly Store Eggs: A Scientific Approach 0 11

Proper Storage Conditions for Eggs

The question of how to properly store eggs sparks debates even among food technology specialists, let alone ordinary consumers. Some argue that eggs can absorb foreign odors in the refrigerator, which can lead to unexpected flavors, such as an omelet with a fishy taste. It is no coincidence that eggs are often placed on regular shelves in stores. Others, on the contrary, believe that low temperatures prevent the proliferation of salmonella bacteria, and that is why eggs should be stored in the refrigerator, but not in the door, rather on the shelves inside, reports Doctorpiter.

This time, the arguments in favor of storing eggs at room temperature turned out to be more convincing. Scientists from the University of Newcastle conducted a study in which eggs stored under various conditions were subjected to freeze-drying. As a result, a powder was obtained, which was tested for vitamin D3 content—one of the forms of vitamin D. This vitamin plays an important role in RNA and DNA transcription, participates in protein and lipid metabolism, and supports the normal functioning of the digestive system.

The results of the study were quite curious: eggs that had been in the refrigerator for 28 days contained less vitamin D3 than those stored at room temperature. We remind you that according to standards, table eggs can be stored without refrigeration for up to 25 days if the room temperature does not exceed +20 degrees.

In addition, scientists investigated how much vitamin D is retained in cooked eggs. For this, they made an omelet, fried eggs, boiled eggs hard, and made poached eggs.

A Common Mistake in Boiling That Can Make Eggs Harmful to Health

The worst result was shown by fried eggs: they retained only 78% of the initial vitamin content. Boiled eggs retained 80% of vitamin D, while poached eggs retained 93%.

However, the omelet and scrambled eggs demonstrated better results, with vitamin D content increasing to 109%. The scientists noted that even using a microwave did not affect the concentration of the vitamin in these dishes.
