When eggs are cooked, they turn from a liquid or plasma state into a solid, albeit rubbery, one. But not every bit of the liquid disappears. When you microwave the egg, tiny pockets of the remaining water become superheated, and when air is added—by puncturing or slicing the whites—the egg spontaneously boils. 5 июн. 2019 г.

How do you keep eggs from exploding in the microwave?

Sprinkle a few grains of salt into bottom of container (salt attracts microwave energy and helps to cook egg evenly). Break one or two eggs into container. Pierce yolks and whites with fork four or five times to bottom of container (piercing is necessary to prevent “exploding” during cooking).

What causes an egg to explode?

There are a variety of microorganisms that can contaminate the egg, but generally exploding eggs are the result of Pseudomonas spp., a gas-producing bacterium. These eggs start appearing around day 18 of incubation when contents may ooze out of the shell pores.

Is it bad to microwave eggs?

When an egg is heated in the microwave, pressure builds up inside. This can occur with an intact shell as well as with egg yolks with open shells and even pierced yolks, according to the researchers. Previous cases of exploding eggs causing trauma to the face, eyelids, and cornea of the eye have been reported.

Why boiled egg explodes in microwave?

The answer has yet to be proven why hard-boiled eggs explode after they are reheated in the microwave, but according to one theory (via JASA), “The egg yolk develops many small pockets of superheated water, leading to an increasingly unstable condition.

Why do hard boiled eggs burst in the microwave?

Eggs burst when microwaved on high heat because steam builds up in the yolk and expands beyond the shell’s resistance. Whole eggs in the shell should not be microwaved unless you can pierce the shell and yolk, perhaps multiple times, to allow steam to escape.

Can an egg explode in a microwave?

An egg will not explode in a microwave as long as you don’t power on the microwave. Don’t cook any eggs in the microwave that have not been scrambled. The yolk of the egg must be broken to safely cook eggs in the microwave. So, omelets and scrambled eggs are the only safe eggs to cook in a microwave.

How does a microwave heat up an egg?

Microwave heats by vibrating water molecules. Even hard-boiled eggs have sufficient moisture for the moisture to heat up to steam. The shell keeps the steam inside till pressure builds up sufficiently to overcome the shell.

What happens to egg yolk when it is microwaved?

It is a scientifically proven fact that “when a liquid changes into vapour form it creates an enormous pressure around the walls of the container”. So, it is clear that egg yolk inside the egg which is in a microwave will form a minor vapour creating a high pressure zone inside the egg and egg shell will burst up.
