How long is the shelf life of raw eggs? Can you still eat it in the refrigerator for 3 months? These five kinds of eggs must not be eaten!

Eggs are one of the protein foods we often eat. Many people think that eggs can be kept for a long time, as long as the shell is not broken. In fact, this is a wrong idea, and eggs also have a shelf life. So how long is the shelf life of raw eggs? Can you still eat it in the refrigerator for 3 months?

1. How long is the shelf life of raw eggs

Generally, raw eggs can be kept for about 1 month at room temperature, 15 days at room temperature in winter and 10 days at room temperature in summer.

Note: many people like to wash eggs and then store them. In fact, this will destroy the original outer shell membrane of eggs, make bacteria and microbes flow into the eggs, and accelerate the deterioration of eggs.

2. How long is the shelf life of eggs in the refrigerator

1. When the temperature of the refrigerator is 2-5 ℃, the eggs can be kept for about a month.

2, the egg refrigerator can not eat for 3 months, has been broken, although there is no difference on the surface, but the yolk inside has stinky. The editor has such experience. After putting the bought eggs in the refrigerator, it has not been managed. A month later, the eggs are a little bad and cannot be eaten, so it is better to eat the bought eggs as soon as possible.

3. Eggs can not be eaten after five months, because the mucin in the protein will slowly dilute under the action of protease, and the egg yolk can not be fixed. There are already bacteria that can't be eaten.

3. Preservation methods of raw eggs

1. Eggs should be placed with big head up and small head down, so that the egg yolk can be floated and affixed to the bottom of the air chamber, which can not only prevent microbes from invading the egg yolk, but also prolong the shelf life of the egg.

2. If the purchased eggs can be eaten within a week, just use the egg holder to put it in a ventilated and backlit place, not in the refrigerator (except in summer).

3. If you buy more than you can store in the refrigerator, you can put the eggs in a well-ventilated and backlit place, and then put some soybeans or other grains in the box where the eggs are stored to reduce the respiration of the eggs.

4. Clean the dirty eggs with a dry cloth before storing them in the refrigerator. Be careful not to wash the eggs that need to be preserved with water.

4. How long can eggs be kept in summer

1. Raw eggs

Raw eggs can not be kept for more than three days at room temperature. if they are kept in the refrigerator for a longer time, they can be kept for about a month.

2. Hard boiled eggs

If stored at room temperature, hard-boiled eggs can only be preserved for 1 to 2 days in summer, because the summer temperature is high, and there are a variety of microbes in cooked eggs, which reproduce quickly at high temperature, and eggs are easy to deteriorate.

If it is put in the refrigerator, it can be preserved for more than ten days under the condition that the eggshell is not damaged, but some microbes in the egg may also affect the quality of the egg in the refrigerated environment, and it should be heated again when eating it. Only in this way can we ensure the safety of eating.

5. Can you eat eggs without smelly for a long time

Such smelly food is definitely not recommended. There are a lot of bacteria in it. May cause inflammation of the gastrointestinal tract.

You can't eat these five kinds of eggs.

1. Cracked eggs

Eggs in the process of transportation, storage and packaging, due to vibration, extrusion and other reasons, some eggs will cause cracks, cracks, easy to be invaded by bacteria, if placed for a long time is not suitable for consumption.

2. Sticky shell eggs

This kind of egg is stored for too long, the yolk membrane changes from tough to weak, the yolk is close to the eggshell, if the part is red, you can eat it, but the egg membrane is close to the eggshell, the skin is dark black, and there is a peculiar smell, it is not suitable to eat again.

3. Rotten eggs

Because the bacteria invade the egg and multiply in large numbers, the eggshell is dark gray, and even the eggshell is ruptured by the expansion of hydrogen sulfide gas inside the egg, while the mixture in the egg is grayish green or dark yellow and has a bad smell, then the egg can not be eaten, otherwise it will cause bacterial food poisoning.

4. Loose yellow eggs

Due to transport and other fierce oscillations, the yolk membrane ruptured, resulting in mechanical yolk, or stored for too long, bacteria or mold invaded the egg through the eggshell stomata, and destroyed the protein structure, resulting in scattered yolk, egg liquid thin and turbid. If the loose yellow is not serious, there is no peculiar smell, it can still be eaten after boiling and other high temperature treatment, but if the bacteria reproduce in the egg, the protein has been denatured and cannot be eaten with a bad smell.

5. Stillborn eggs

Eggs in the hatching process due to bacteria or parasites pollution, coupled with poor temperature, humidity conditions and other reasons, the eggs that cause the embryo to stop developing are called stillborn eggs. The nutrition of this kind of egg has changed. If the egg dies for a long time, the protein will be decomposed to produce a variety of toxic substances, so it is not suitable for consumption.
