Whats in a cheese? Just look at label
I noticed it says natural cheese on the label of my favorite cheese. Isnt all cheese natural?
It all depends on your definition. In the world of cheese, the word natural differentiates your favorite cheese from its processed counterpart.
Natural cheeses are made by separating milk into curds and whey. The watery whey is drained off, and, with the help of bacteria, enzymes and, often, rennet, the curds ferment and sooner or later become cheese. Natural cheeses include fresh, or unripened, cheese such as ricotta, cream cheese and cottage cheese, and ripened cheese, which ranges from soft (including brie and camembert) to very hard (such as parmesan and romano) to everything in between (including cheddar, swiss, gouda and muenster).
Processed cheese, also called process cheese or American cheese, is made by blending natural cheeses, both aged and unripened, pasteurizing them, and adding emulsifiers for smoothness. For longer shelf life, salt and preservatives are also added. The texture of processed cheeses is much smoother than that of natural cheese, and it depends on your personal preference whether thats a good or bad thing. Processed cheeses melt easily, slice easily, keep for a long time, and are uniform in texture, flavor and appearance.
You also will see products labeled Ã¢â¬Åpasteurized processed cheese food or pasteurized process cheese spread. They contain additional liquid, such as milk or whey, and stabilizers for softness. Food and Drug Administration standards say these products must contain at least 51 percent cheese. Processed cheese food has a maximum moisture content of 44 percent, while the spread has a moisture content of between 44 percent and 60 percent.
If youre really interested, the FDAs U.S. Code of Federal Regulations (Title 21, Part 133) lists specific standards for more than 70 different cheese products, from asiago to swiss, including the precise definitions for products such as pasteurized process cheese food.
According to the Dietary Guidelines for Americans, one serving of natural cheese is a mere 1.5 ounces. Because of its higher moisture content (and thus lower calorie count per ounce), you can have a full 2 ounces of processed cheese for a serving.
