Fresh mozzarella is made from whole milk which results when buffalo, cow or goat milk is mixed with rennet. Curds form which are then heated and stretched until the cheese reaches its characteristically soft consistency. Fresh mozzarella always has a high moisture content of at least 50% and is very soft and very creamy. It is prized Italian cheese. Processed mozzarella is real cheese cut with other, non-cheese ingredients. Those extra ingredients can include salt, food dyes, preservatives, extra dairy, emulsifiers, or other artificial ingredients. These ingredients are added to melted, pasteurized cheese, which is then converted to a sliced solid. Processed mozzarella has less than 50% moisture to make it less perishable. It is sold like other commercial cheeses in balls, slices, shreds or sticks.
