One of the biggest consumer benefits of processed cheese is "the melt". The use of emulsifiers in processed cheese lets it melt smoothly and uniformly when heated. It is made with regular cheese, but with the addition of whey, emulsifiers, milk, salts, preservatives, and food coloring.
The top uses for processed cheese are cheeseburgers and grilled cheese sandwiches.
Legally, processed cheese cannot be sold as "cheese". It needs to be called a "cheese food". In fact, the FDA highly regulates how products can be labeled based on their cheese ingredient, moisture content, and milkfat.
