Yolk
What is Yolk?
Yolk refers to the yellow part of an egg, which is surrounded by the egg white. It's naturally occurring and is primarily made up of fats, proteins, and essential nutrients such as choline and vitamins A, D, E, and K.
Egg yolks are valued in culinary applications for their rich flavor, emulsifying properties, and nutritional content. Health discussions around yolks often focus on their cholesterol content. While yolks do contain cholesterol, recent studies suggest dietary cholesterol may not significantly impact blood cholesterol levels for most people.
When you see yolk on a label, it often indicates the product uses eggs as a binding or enriching ingredient. This can be common in baked goods, sauces, and dressings.
