Egg Yolk Powder

Egg yolk powder is a dehydrated form of egg yolk, commonly used as a food ingredient due to its rich nutritional profile. It is produced by spray-drying liquid egg yolk to preserve its properties while enhancing shelf life and convenience. Egg yolk powder is widely used in food processing, baking, cosmetics, and dietary supplements.

Production Process:

1. Collection of Egg Yolk: Fresh eggs are cracked, and the yolk is separated from the egg whites.

2. Pasteurization: The egg yolk undergoes pasteurization to eliminate pathogens and bacteria, ensuring safety for consumption.

3. Spray Drying: The pasteurized liquid yolk is then spray-dried to convert it into a fine powder. This process helps preserve the nutritional content while increasing the shelf life.

4. Packaging: The powdered egg yolk is packaged under controlled conditions to prevent moisture absorption and ensure freshness.
