Various proteolysis indices (nitrogen content of different fractions a
nd PAGE of the casein and water soluble fractions) were determined for
6 types of cheese: Beaufort, Parmigiano Reggiano, Appenzeller, Fontin
a, Comte and Mahon. A Cluster analysis was then applied to estimate th
eir usefulness for the differentiation of the cheeses. The results obt
ained from the samples form perfect groups according to the variety.
