Flavor comparison of natural cheeses manufactured in different countries.

The objective of this study was to determine the main flavor components of different natural aged cheese types from various countries and determine whether a unique sensory characteristic exists within specific countries for European cheeses. The flavor of 152 cheeses from Estonia, France, Italy, Germany, Holland, Austria, England, Greece, Ireland, Spain, Switzerland, Sweden, Belgium, and Denmark were described during 4 independent studies. The sensory data from these studies were combined. The cheeses were sorted according to milk type and texture, and flavor characteristics of these groups were described. The main flavor characteristics of the cheeses tested were salty, sweet, sour, astringent, biting, pungent, sharp, nutty, musty/earthy, dairy fat, buttery, and dairy sweet. The cluster analysis divided the cheeses into 4 clusters: clusters 1 and 2 were sour, dairy sour, salty, astringent, biting, and varied in buttery (cluster 1) and sharp notes (cluster 2). Cluster 1 and 2 were mainly composed of French cheeses, while clusters 3 and 4 represented cheeses from various countries. Cluster 3 and 4 were sweet, with cooked milk and nutty characteristics and varied from buttery (cluster 3) to sharp notes (cluster 4). Cheeses from some countries, for example, France and Estonia, generally exhibited common sensory characteristics within the specific country, but cheeses from some other countries, such as Italy, varied widely, and seemed to have no common sensory theme. Most regional cheese standards are not specific about flavor profiles and these results suggest it may be possible to start a further characterization of cheeses in some countries.
