Egg whites are a fantastic kitchen staple, prized for their versatility and nutritional benefits. Whether you’re whipping them into a fluffy meringue, adding them to a salad for extra protein, or using them as a binder in recipes, it’s essential to know how to store them properly to maximize their freshness. One common question arises: how long can you keep egg whites in the refrigerator? This article will explore how to store egg whites, how long they last, tips for extending their life, and delicious recipes to make the most of leftover egg whites.
The Basics of Egg Whites
Egg whites, also known as albumen, compose about two-thirds of the egg’s total weight. They are an excellent source of protein, low in calories, and fat-free, making them a popular ingredient in many health-conscious recipes. They also feature in various culinary applications, from baking to savory dishes, and their ability to form foams makes them essential for creating meringues and soufflés.
How to Store Egg Whites Properly
To maximize the lifespan of your egg whites, it is vital to store them correctly. Here are the key steps to ensure your egg whites stay fresh for as long as possible:
1. Use Clean, Dry Containers
Always store egg whites in clean, dry containers. Glass or plastic containers with tight-fitting lids work best to minimize exposure to air. Avoid using metal containers, as they can react with the proteins in the egg whites.
2. Refrigerate Immediately
If you separate egg whites from yolks, make sure to refrigerate them as soon as possible. Keeping them at room temperature can lead to spoilage. The ideal temperature for storing egg whites is between 33°F and 40°F (1°C to 4°C).
3. Label and Date the Container
Always label the container with the date you stored the egg whites. Freshness is key, and knowing when you stored them will help you manage your supplies more effectively.
How Long Do Egg Whites Last in the Refrigerator?
Typically, raw egg whites can be kept in the refrigerator for about four days. However, various factors can influence their longevity:
1. Storage Conditions
If stored in an airtight container and kept at a consistent refrigerator temperature, you may achieve the maximum shelf life.
2. Separation Method
If you used an eggshell to separate the whites, it’s best to use them promptly to prevent contamination from any residual yolk. If you use a cleaner technique, such as an egg separator, the egg whites may have a slightly longer shelf life.
3. Pasteurized Egg Whites
If you’ve purchased pasteurized egg whites, they can last up to ten days in the refrigerator after opening, given they are stored properly. Unopened cartons of pasteurized egg whites can typically last for several weeks past the “best by” date when refrigerated.
Signs of Spoilage
When assessing the freshness of your egg whites, look out for these signs of spoilage:
- Off odor: Spoiled egg whites will emit a distinct sour smell.
- Color changes: Fresh egg whites should remain clear. If they start to become cloudy or yellowish, it’s best to discard them.
Freezing Egg Whites for Extended Storage
If you find yourself with excess egg whites that you cannot use in four days, consider freezing them. Freezing extends their shelf life significantly, allowing you to store egg whites for up to one year. Here’s how to do it:
1. Prepare for Freezing
Before freezing, ensure your egg whites are thoroughly mixed. This helps to break down the proteins that may cause the whites to separate when thawed.
2. Use Ice Cube Trays
Pour egg whites into ice cube trays to create convenient single-serving portions. Once frozen, transfer the cubes to a resealable freezer bag, labeling them with the date.
3. Thawing Frozen Egg Whites
To thaw frozen egg whites, transfer them to the refrigerator overnight or set them in a bowl of cool water for a quick thaw. Never thaw egg whites in the microwave, as they may cook unevenly.
Delicious Recipes to Use Leftover Egg Whites
Instead of letting your egg whites go to waste, try these delightful recipes.
1. Meringues
Meringues are a timeless classic that uses egg whites to achieve a light, airy texture. Combine egg whites with sugar and a touch of vanilla, whip until stiff peaks form, and bake until crisp.
2. Angel Food Cake
This fluffy dessert is made primarily from egg whites and is perfect for showcasing their unique properties. Pair it with fresh fruit or a light whipped cream topping for a delightful treat.

How long can egg whites be stored in the fridge?
The egg whites can typically be stored in the refrigerator for about two to four days when kept in an airtight container. It’s essential to ensure that the container is sealed properly to maintain freshness and prevent any contamination from other foods in the fridge.
If you’ve opened a carton of egg whites, it’s crucial to check the expiration date on the package before storing them. Using them within this timeframe ensures the best quality, taste, and safety for your meals or recipes.
Can you freeze egg whites for longer storage?
Yes, egg whites can be frozen for long-term storage. When freezing, it’s best to use ice cube trays to portion them out, which allows for easy measurement later. Once frozen, transfer the egg whites to a freezer-safe bag or container, removing as much air as possible before sealing.
Frozen egg whites can last for up to a year in the freezer. When you’re ready to use them, just thaw them in the refrigerator overnight or under cold running water. Always ensure that they are properly thawed before incorporating them into your dishes.
How can I tell if egg whites have gone bad?
To determine if egg whites have gone bad, look for any changes in color or consistency. Fresh egg whites should be clear to slightly opaque. If you notice a yellowish tint or a cloudy appearance, it’s best to discard them, as these can be signs of spoilage.
Additionally, smell can be a crucial indicator. Spoiled egg whites may have an off or unpleasant odor that is clearly discernible. If they smell bad, it’s safer to err on the side of caution and throw them away.
Are pasteurized egg whites safe for raw consumption?
Yes, pasteurized egg whites are safer for raw consumption compared to non-pasteurized ones. Pasteurization involves heating the egg whites to a temperature that kills harmful bacteria without cooking the egg. This process significantly reduces the risk of foodborne illnesses.
You can find pasteurized egg whites in cartons at most grocery stores. They are ideal for recipes such as mousses, mayonnaise, or protein shakes, where raw egg whites are commonly used.
Can I use expired egg whites that are within the recommended refrigeration period?
Using egg whites that are past their expiration date is generally not advisable, even if they appear fresh and have been stored correctly. The expiration date is there to ensure food safety, and consuming expired products can increase the risk of foodborne illness.
Always prioritize safety by checking for any signs of spoilage before using egg whites, even if they are within the recommended refrigeration period. If you have any doubts, it’s better to discard them.
What is the best way to store egg whites in the fridge?
To store egg whites properly in the fridge, transfer them into an airtight container immediately after separating them from the yolks. Label the container with the date to keep track of how long they’ve been stored. This helps you maintain freshness and ensures the egg whites are used while still safe.
The ideal temperature for storing egg whites is between 33°F and 40°F (1°C to 4°C). Keeping them near the back of the fridge, where temperatures are most consistent, can also help prolong their freshness.
Can you use egg whites after the sell-by date on the carton?
The sell-by date is not an absolute indicator of safety, as many egg products, including egg whites, can still be safe to consume after this date if they have been stored properly. However, it’s important to check for signs of spoilage, such as odor, discoloration, or unusual texture before using them.
If the egg whites were refrigerated continuously and show no signs of spoilage, they may still be viable for cooking or baking. Use your best judgment and err on the side of caution if you’re unsure.
How do you separate egg whites from yolks effectively?
To separate egg whites from yolks effectively, you can simply crack the egg and gently pass the yolk between the two halves of the shell. This allows the white to fall into a bowl while leaving the yolk in one half of the shell. This method requires a steady hand and some practice, but it can be quite efficient.
Alternatively, you can use an egg separator, which is a specialized kitchen tool designed for this purpose. It sits over a bowl and catches the yolk while letting the egg white pass through. This method can be especially helpful if you’re separating multiple eggs at once.
