Eggs and Egg-Derived Products Testing

Eggs are often referred to as nature’s most complete food due to their exceptional nutritional profile. They provide high-quality protein of the highest biological value along with essential lipids, vitamins, and minerals. Each component of the egg—shell, yolk, and albumen (egg white)—plays a significant role in preserving the overall quality.

However, eggs are a highly perishable commodity, making their quality assurance from farm to fork a critical challenge. Increasing regulatory demands and consumer expectations require that egg producers and processors implement stringent quality control practices to stay competitive and safe.

 

Applications of Egg-Derived Products in the Food Industry

Eggs are processed into a wide range of versatile products used across multiple food sectors:

• Liquid Eggs (whole eggs and yolk-enhanced variants)

• Frozen Eggs (whites, yolks, whole eggs)

• Dried & Powdered Eggs

• Spray-Dried Egg Powders

• Egg Protein Powders & Meringue Powders

• Egg-Based Mayonnaise & Pasta

• Scrambled & Fried Ready-To-Eat Eggs

• Egg Substitutes (based on egg white, whey, dextrose, etc.)

• Instant Egg White Solids, Whole Egg Solids, Egg Yolk Solids

• Whole Hard-Cooked Eggs

Egg processing includes a series of steps such as collection, handling, washing, grading, candling, breaking, pasteurization, drying, freezing, cold storage, packaging, and quality control. Preservation methods like pasteurization, freezing, and drying help extend shelf life and maintain product integrity.

 

Egg Quality & Safety Parameters

Egg quality is assessed based on:

• External Characteristics: Shell cleanliness, shape, color, texture, and weight

• Internal Characteristics: Yolk placement, albumen quality, air cell size, porosity

Due to their widespread use in food processing, egg safety is paramount, especially considering their allergenic potential, particularly egg white proteins which affect nearly 2% of children globally.

Moreover, contamination incidents such as the detection of fipronil insecticide in egg samples (EU, 2017) have led to stricter regulations. Under EU Regulation EC No. 396/2005, the maximum residue limit (MRL) for fipronil in eggs is 0.005 mg/kg.
