Most people love cheese, whether in chunks or strips, or melted on bread for a grilled sandwich. It is a part of the cuisine of nearly every culture, and variations on the theme are legion. Cheese is usually categorized into four types: soft, semi-soft, semi-hard and hard.
The main ingredient in cheese is milk. Cheese is made using cow, goat, sheep, water buffalo or a blend of these milks. The type of coagulant used depends on the type of cheese desired. For acid cheeses, an acid source such as acetic acid (the acid in vinegar) or gluconodelta-lactone (a mild food acid) is used.resh cheeses, such as cream cheese or queso fresco, are made by direct acidification. Most types of cheese, such as cheddar or Swiss, use rennet (an enzyme) in addition to the starter cultures to coagulate the milk.
