What is the primary characteristic of process cheese?

The primary characteristic of process cheese is that it has a smooth texture achieved by reworking multiple types of cheeses. This process involves melting and emulsifying the cheeses along with other ingredients, which allows for a consistent, uniform product that is easy to slice, melt, or spread. The combination of various cheeses also helps to enhance flavor and texture while providing stability during storage.

While process cheese can contain added preservatives, this is not its defining characteristic; rather, it is a common practice to prolong shelf life and improve safety. The notion that it is made from a single type of cheese is also inaccurate, as process cheese specifically involves blending different cheeses for better texture and flavor. Additionally, the aging period for process cheese is generally shorter than for traditional cheese varieties, focusing instead on the characteristics that come from the manufacturing process rather than aging.
