In this brief guide, we are going to answer the question “How long do pasteurized eggs last?”, discuss answers to other related questions like why is it important to refrigerate pasteurized eggs and are raw pasteurized eggs safe to eat.

How long do pasteurized eggs last?

Pasteurized eggs only last for less than 2 hours at room temperature and they last for 10 days in the fridge (if unopened). After this duration, the optimal eating quality of pasteurized eggs will have deteriorated so much that they will not taste good and they might not remain safe to eat.

Why is it important to refrigerate pasteurized eggs?

Pasteurized eggs, if left unrefrigerated, may not remain good to be used or consumed. This is because, at room temperature, the proteins of eggs degrade more quickly. Also, the room temperature offers a favorable environment to the microorganisms particularly bacteria to grow on the eggs.

Protein degradation

Eggs stored at room temperature will degrade more quickly than those stored in the refrigerator. Because as eggs age, their protein structure degrades. This causes older egg whites to become runnier, and the yolks to stand less round and tall. The warmer the room temperature, the more this is true. So it is better to keep the eggs in the refrigerator than to keep them in the kitchen.

Bacterial growth

Storing eggs at home temperature encourages bacterial growth. Eggs are particularly more susceptible to one particularly nasty bacteria, named Salmonella. This bacteria can be a reason for a very severe form of food poisoning, with symptoms developing from 12-72 hours after infection.

Can you freeze pasteurized eggs?

It is not recommended to freeze pasteurized eggs. However, if you want to store the eggs longer than their shelf-life in the refrigerator, you can freeze them. To freeze eggs, it is important to crack them in a freezer-safe container and you can keep them for even a year or more.

How to store pasteurized eggs?

To keep pasteurized eggs fresh for a longer period, it is better to store them in the carton because the carton protects the eggs and prevents the eggs from absorbing the strong odors and flavors of other foods in your fridge through the thousands of tiny pores in the eggshell. And, also the best-by date is always visible to you on the eg carton so you can guarantee freshness.

Eggs should always be stored with the large end up, the same way they are packaged in the carton, to help the yolk remain centered.

Do not store eggs in the door of the refrigerator but store them in the main body of the refrigerator. This will ensure that they keep a consistent and cool temperature.

Leftover raw egg whites and yolk should be kept in air-tight containers and stored in the refrigerator immediately. To prevent yolks from drying out, cover them with a little cold water and drain this water before using the yolk.

Are pasteurized eggs healthy?

Pasteurized eggs are thought to be healthy than normal eggs as the risk of Salmonellosis is reduced to a minimum due to the pasteurization process, however, they are not healthier than normal eggs at all as they neglect the innate defense mechanisms that eggs are naturally equipped with.

Moreover, the pasteurization process also wipes out all the good bacteria within the egg (some bacteria are necessary for proper digestion) and could also have a negative impact on the egg’s vitamin and mineral content.

Are raw pasteurized eggs safe to eat?

The most obvious issue related to eating raw eggs is associated with acquiring foodborne illness, especially salmonellosis. During pasteurization, the bacteria that are to be found in the egg are killed, and therefore, pasteurized eggs are safe to eat even if they are raw.

The USDA recommends using these eggs for uncooked dishes such as homemade mayonnaise, Hollandaise sauce, or Caesar salad dressing. Since these dishes rely on beaten eggs, pasteurized eggs are a convenient choice, as you don’t have to separate the eggs and they beat more easily than raw eggs.

How to tell if pasteurized eggs have gone bad?

The sniff test is the most easiest and convenient way to determine if an egg has gone bad. A bad egg will give off a foul odor when cracked. This smell will be present even after the egg has been cooked.

If you have kept eggs in their original carton, you can check for the expiration date to see whether the eggs are gone bad or are still good to be used.
