Are eggs with a solidified yolk still safe to eat?
Generally speaking, whether an egg with a solidified yolk can still be eaten mainly depends on the cause of the yolk solidification. If the yolk solidifies due to cooking, the egg is usually still edible. However, if the yolk solidifies due to exposure to high temperatures or humid conditions, the egg typically should not be consumed. Detailed explanations are as follows:

If the egg yolk solidifies during normal cooking processes, such as boiling, frying, or sautéing, and the egg itself is fresh and odorless, then it is safe to eat. Heating during cooking causes the proteins to denature and solidify, which is a normal phenomenon that does not affect the egg's nutritional value or food safety.
If eggs have been stored for a prolonged period under high temperature or humid conditions, even if the yolk solidifies, there may be a risk of bacterial growth. In this case, the egg may have already spoiled and should not be consumed to avoid food poisoning or other health issues.
It is recommended to maintain good storage habits, regularly check the freshness of eggs, and ensure eggs are thoroughly cooked during preparation.
