How long can you keep cooked egg whites unrefrigerated?

It is generally advisable to refrigerate cooked egg whites within two hours of cooking, as they can quickly become unsafe for consumption at room temperature. Bacteria thrive in warm and moist environments, and cooked egg whites are a good source of protein and moisture, making them susceptible to bacterial growth. In order to maintain food safety, it is best to refrigerate cooked egg whites within the recommended time frame.
