Pasteurized processed cheese is a blend of fresh and aged natural cheeses that have been shredded, mixed and heated (pasteurized), after which no further ripening occurs. It melts easily when reheated. The blend may consist of one or more varieties of natural cheese and may contain pimentos, fruits, vegetables, or meats. Smoked cheese or smoke flavor may also be added.

The flavor of pasteurized process cheese depends largely on the flavor of the cheese used, and may be modified by flavorings added. Pasteurized Gruyere cheese has a nutty sweet flavor, somewhat similar to Swiss.

Other available varieties are pasteurized process American cheese, pasteurized process Swiss cheese, pasteurized process Swiss cheese blended with American, and pasteurized process Brick cheese. Process cheese is packaged in slices, 1/2, 1, 2, and 5-pound loaves, and cut portions. It may be used in main dishes, for snacks and cheeseburgers, with cold cuts and salads, on grilled or toasted sandwiches, in numerous sandwich combinations, and in casseroles.

All pasteurized process cheese products should be kept refrigerated after opening.
