Cream cheese
Cream cheese is a soft, usually mild-tasting fresh cheese made from milk and cream. Cream cheese is not naturally matured and is meant to be consumed fresh, so it differs from other soft cheeses such as Brie and Neufchâtel. It is more comparable in taste, texture, and production methods to Boursin and mascarpone. Stabilizers such as carob bean gum and carrageenan are often added in industrial production. The U.S. Food and Drug Administration defines cream cheese as containing at least 33% milk fat with a moisture content of not more than 55%, and a pH range of 4.4 to 4.9. Similarly, under Canadian Food and Drug Regulations, cream cheese must contain at least 30% milk fat and a maximum of 55% moisture. In other countries, it is defined differently and may need a considerably higher fat content. Cream cheese originated in the United States in the 1870s.
