THE FLAVOR OF CHEESE.
Cheese owes its flavor to the fatty acids and their compounds which it contains and to ammonia-like bodies formed during ripening from the cleavage of the casein, to salt added to the curd, and in some varieties, like Roquefort, to bodies elaborated by molds which develop in the cheese. In the highly flavored sorts some of the fatty acids of a very marked odor are present in abundance, as are also the ammonia-like bodies. Indeed, in eating such cheese as Camembert a trace of ammonia flavor may often be plainly detected.
The cleavage of the nitrogenous material of the cheese and other changes are brought about chiefly by the action of enzymes originally present in cheese or by microorganisms and are to be regarded as fermentative and not as putrefactive changes.
The liking for highly flavored cheeses of strong odor is a matter of individual preference, but from the chemist’s standpoint there is no reason for the statement often made that such cheeses have undergone putrefactive decomposition.
