Extended data

Some families put preserved eggs (preserved eggs) in the refrigerator or even freeze them, thinking that they can be preserved for a long time without deterioration. In fact, on the contrary, preserved eggs are made of alkaline substances, which are gelatinous and contain about 70% water. After freezing, water will gradually freeze.

At this time, when the preserved egg is taken out to eat, the ice cubes will gradually melt and its colloid will become honeycomb, which changes the original mellow flavor of the preserved egg and reduces the edible value. Moreover, low temperature will make preserved eggs yellow in color and hard in taste, which is very different from normal preserved eggs. Therefore, preserved eggs are not suitable for storage in the refrigerator.

If you can't finish eating preserved eggs that need to be preserved for a period of time, you can put them in plastic bags and seal them. Under normal circumstances, preserved eggs that have not been peeled should be placed in a ventilated and dark place with relatively low temperature, but the time should not be too long, not more than one month. However, the shelf life of peeled preserved eggs is only two hours, so you should eat them as soon as possible and not leave them for the next meal.
