Abstract: There is a method of producing a hydrolysed egg yolk plasma product from egg yolk elements. The egg yolk elements include phospholipids and proteins. The method comprises introducing a hydrolysing agent into the egg yolk elements to hydrolyse at least a portion of the proteins in the egg yolk elements to form the hydrolysed egg yolk plasma product. There also is a composition formed using the method above. There is also an egg yolk composition formed from egg yolk, comprising at least 15% phospholipids solids by dry mass, at least 20% protein by dry mass, the protein being at least partially hydrolysed into peptides and at least 40% lipids other than phospholipids by dry mass.
