For most people, eggs are a staple food, ubiquitous in their diet. How do we usually consume eggs? Boiled, fried, steamed—these are some of the common methods. But what other ways can we prepare eggs? Today, let’s explore a novel method: freeze-dried eggs.
Getting to Know Freeze-Dried Eggs
What are freeze-dried eggs?
Freeze-dried eggs are made by removing moisture from eggs in a low-temperature vacuum using a freeze dryer. This process preserves most of the nutritional content of the eggs, thereby extending their shelf life.
Are freeze-dried eggs healthy?
Nutritionally, freeze-dried eggs are almost equivalent to fresh eggs. The freeze-drying process, performed in a low-temperature vacuum, retains over 95% of the nutritional content. This means freeze-dried eggs remain a high-quality source of protein and can be consumed with the same confidence as fresh eggs.
How long can freeze-dried eggs be stored?Are freeze dried eggs shelf stable?
The removal of moisture during the freeze-drying process significantly extends the shelf life of eggs beyond that of regular eggs. While ordinary eggs can last about a month in the refrigerator, freeze-dried eggs stored in airtight bags or Mason jars can last for decades, even up to 25 years, without losing their nutritional value. Therefore, freeze-dried eggs are an ideal choice for long-term food storage.
The difference between freeze-dried eggs and egg powder
Are freeze dried eggs the same as powdered eggs?
As substitutes for fresh eggs, both freeze-dried eggs and egg powder offer the convenience of use and easy storage. However, they have some differences:
- Production process: Freeze-dried eggs are made by sublimating water in a low-temperature vacuum, whereas egg powder is produced by evaporating moisture in a heating chamber through spray drying.
- Texture and taste: After rehydration, freeze-dried eggs’ texture and taste are closer to those of fresh eggs. In contrast, the high temperatures used in the production of egg powder change its texture, resulting in a different taste and texture after reconstitution compared to fresh eggs.
- Nutritional value: Freeze-dried eggs retain most of their nutrients (including proteins, vitamins, etc.) through the process, while egg powder may lose some nutritional value due to the high temperatures involved in the drying process.
Which is better: freeze-dried eggs or dehydrated eggs?
Due to their different production processes, freeze-dried eggs and dehydrated eggs are not the same.
- Nutritional content: Freeze-dried eggs are made in a low-temperature vacuum, which better preserves nutrients. Dehydrated eggs are made using hot air to remove moisture, which can alter some protein structures and result in the loss of some vitamins.
- Texture and Taste:Freeze-dried eggs can more closely replicate the taste and texture of fresh eggs after rehydration, while dehydrated eggs undergo a change in taste and texture due to the heat applied during the dehydration process to remove moisture.
- Shelf Life: Both freeze-dried and dehydrated eggs have a long shelf life, but freeze-dried eggs achieve a more thorough moisture removal (our household freeze-dryers can eliminate more than 99.5% of moisture), resulting in a longer shelf life.
- Cost and Price: The production process for freeze-dried eggs is more complex and costlier, making them more expensive. Dehydrated eggs are relatively cheaper and widely used.
Thus, freeze-dried eggs are superior to dehydrated eggs in terms of nutritional value, taste, and texture, as well as shelf life. However, due to their complex production process, their production costs and prices are higher than those of dehydrated eggs. You can choose according to your actual situation.
How to consume freeze-dried eggs?
- Reconstitute with water: Simply add freeze-dried eggs to water at a recommended ratio (one part freeze-dried egg to three parts water), stir well to fully rehydrate, and the mixture returns to a liquid egg form. The reconstituted egg mixture can be used directly like fresh eggs to make fried or scrambled eggs, etc.
- As a cooking ingredient: Freeze-dried eggs can also be directly added to ingredients as a component in recipes such as bread, cakes, cookies, etc., gradually rehydrating with the addition of water and stirring.
How many eggs are in a pound of freeze-dried eggs?
According to our measurements, about 40 fresh eggs can make one pound of freeze-dried eggs. This number can vary slightly depending on the size of the eggs.
As a nutritious and healthy new food option, freeze-dried eggs are being embraced by more and more people. In fact, the application of freeze-drying technology is not limited to this; there are many more freeze-dried foods for us to choose from:
