Cheese composition varies greatly from product to product. Cheddar cheese<br />

normally has a milk-fat content of 50% a minimum in total solids and a maximum<br />

moisture content of 39%. Fresh cheeses may have a moisture content of 80%<br />

and fat contents in dry matter of just 5%. The product variety is endless.<br />

Most modern factories begin their manufacturing process by taking in raw<br />

milk, standardizing it to a specified solids content, pasteurizing it and then<br />

using it to manufacture dairy products. Many different processes and products<br />

are are possible in a modern factory to enable the production for example<br />

of either low-fat cheeses or cream cheese. Production standards for dairy<br />

products are tightly regulated to ensure the safety of public health and to<br />

guard against fraud. Typically, governments determine minimum product<br />

standards, covering hygiene and composition, that products must meet before<br />

they can be sold in the market. Commercial organizations also use product<br />

specifications to ensure that standards are met.<br />
