Answer to Question 1
Processed cheese made by combining different varieties of cheddar cheese and emulsifying salts.
Answer to Question 2
Natural cheese is the curd or coagulated proteins (casein) of milk induced by enzymes or acid. Processed cheese is made from a single type of cheese or blends of different varieties with the presence of emulsifiers. Processed cheese includes pasteurized process cheese, cheese food, cold pack cheese food, and cheese spread. These products vary in moisture and the percentage of milk fat. They have a longer shelf life than natural cheese products.
