JAKARTA - Boiling eggs is often considered an easy cooking process, as it only cooks eggs in boiling water for a few minutes. However, researchers revealed that there are techniques and times that participate to produce perfectly boiled eggs.

This perfection is judged by the taste, texture, and nutrients contained in the boiled egg. This perfect way of boiling eggs was revealed by Italian researchers, through a study published in the journal Communication Engineering, reported by the National Post, on Friday, February 14, 2025.

Researchers reveal that perfect boiled eggs are produced in different temperatures, between white and yellow. The yellow reaches 65 degrees Celsius, while the white is 85 degrees Celsius.

The author of the study Pellegrino Musto and his colleagues studied the physique behind the perfectly boiling process of eggs. They design the method of boiling periodically, so that the eggs are not boiled at all times.

First, researchers simulated the process using fluid dynamics software. Researchers then attach their theory to fresh chicken eggs purchased and heating, pots, and food thermometers.

The researchers compared the thickening of eggs to the hard-boiled method (12 minutes in boiling water), soft aka soft-boiled (six minutes in boiling water), and sous vide (one hour in a tub with a temperature of 65 degrees Celsius).

The periodic erosion also involves a softening in boiling water (100 degrees Celsius) alternately for 2 minutes and warm water (30 degrees Celsius) for 2 minutes, 8 times. Thus, the total cooking time for a perfect boiled egg is 32 minutes.

With this method, the texture of boiled eggs is superior to that of boiling in general. Yellows of eggs cooked with periodic boiled methods contain many polyphenols, which are compounds with antioxidant properties that research says have many health benefits.

"Color analysis, texture, and consistency of all egg products are just final evidence of successful cooking experiments, which can inspire exciting new recipes," the researchers wrote in the study.

Not only that, the researchers also said with the results of their studies proving that the knowledge of science behind simple problems can improve even the smallest part of human life. One of them is about cooking and consuming eggs.

"The knowledge of the science behind simple problems can improve even a bit of our daily lives, such as simple actions of eating eggs," they concluded.
