Whole shell eggs are processed into egg products through an automated process involving washing, sanitization, breaking, and separation of components.
Here's a breakdown of the egg processing steps:
-
Washing and Sanitizing: Automated equipment meticulously washes and sanitizes the shells of the eggs to remove any dirt, debris, or bacteria present on the surface. This is crucial for maintaining hygiene and preventing contamination of the egg contents.
-
Breaking: The eggs are then mechanically broken open. Modern egg processing facilities use specialized machines that can break thousands of eggs per hour while minimizing shell fragments in the liquid egg.
-
Separation (if needed): Depending on the desired end product, the whites and yolks are separated. This process is often automated, utilizing sensors and mechanical devices to efficiently divide the egg components. Egg whites and yolks are used in a wide variety of food products, each having different functionalities.
-
Filtering: After breaking and separation (if applicable), the liquid egg product undergoes filtration. This step removes shell fragments, chalazae (the ropy strands that anchor the yolk), and other unwanted solids, ensuring a smooth and uniform consistency.
-
Mixing (if needed): At this point, other ingredients, such as salt, sugar, or other additives, may be mixed into the liquid egg product according to the recipe for the intended end product.
-
Chilling: The liquid egg product is rapidly chilled to inhibit bacterial growth and maintain quality. Cooling the eggs is critical for food safety and preservation.
-
Additional Processing: Depending on the intended use of the processed eggs, further processing may occur, such as:
- Pasteurization: Heating the liquid egg product to a specific temperature for a defined time to destroy harmful bacteria like Salmonella.
- Freezing: Extending shelf life by freezing the liquid egg product.
- Drying: Converting liquid eggs into powdered form for use in dry mixes and other applications.
In summary, whole eggs are transformed into various egg products through a highly automated and controlled process that prioritizes hygiene, efficiency, and food safety.
