Parmesan cheese is prized for its flavor, which is rich in umami sensations. Its use in home cooking throughout the Western world is generally as a condiment with other prepared food dishes, rather than being eaten by itself as in traditional European cheese plates. Kraft Foods is a major North American producer of Parmesan and has been selling it since 1945.
Parmesan cheese (as produced by Kraft and many others) is a true cheese. Nevertheless, processed cheese foods can be found that are flavored to attempt to match the taste of Parmigiano-Reggiano (or at least Parmesan).
