1. Funnel method: Beat the eggs into the funnel and gently shake them at the mouth of the funnel to let the protein flow out. If you need to keep the yolk intact, you can make the funnel mouth bigger.

2. Vessel separation method: separate with special egg white device or egg yolk device. Beat the eggs into the container, then gently squeeze the container to separate the egg white from the yolk.

3. Plastic bottle separation method: Beat the eggs in a bowl, then gently suck the yolk with a clean plastic bottle (smaller), and then pour the yolk into another bowl.

No matter which method you use, you need to pay attention to the following points:

1. The container for separating protein and yolk must be clean and free of oil or moisture.

2. Be careful not to break the yolk in the process of separation, otherwise the egg white and yolk will be mixed together.

3. If you need to separate multiple eggs, it is best to separate only one at a time to avoid mistakes.

4. If you need to use separated egg white or yolk for cooking, it is best to use it as soon as possible after separation, so as not to affect the quality of food.
