Cheese
Cheese is essentially a processed form of casein, or milk protein, which contains butter fat. The milk is generally acidified by the addition of lactic acid bacteria and the curd or casein coagulated by a soluble ferment called rennet. It is then separated from the whey which consists of water, milk, sugar, a little fat and minerals. One part of rennet may coagulate as much as 250 thousand parts of milk. Before the rennet is added the milk may be tested for ripeness for curdling. For this test, a teaspoonful of diluted rennet extract is added to 4 ounces of milk and, if the coagulation takes place within 45 to 60 seconds, the milk is ready for the addition of rennet.
Sour milk cheeses owe their flavours chiefly to the lactic acid produced by the lactic acid bacteria. The characteristic flavours of other varieties of cheese are developed largely during later processing. These flavours result from exposure of the cheese to bacteria, molds, or yeasts that occur naturally or are added.
The striking differences in the flavour and consistency of cheeses may also be due to the type of milk used, e.g. whole milk, skimmed milk, cream, or a combination of milks.
The milk may be derived from cows, goats, sheep or it may be a mixture of these. The time spent in ripening end aging the chees determines the definite characteristics, e.g., for cheddar types the lactic acid bacteria are permitted to develop in great numbers before the rennet is added, whereas in Swiss, Camembert or Limburger cheese, they are not.
Also, in cheddar, the moisture content or whey, left in the curd is considerably less than that present in Camembert; this means that more fermentable milk sugar is present in Camembert. Emmenthaler (Swiss) curd is cooked much longer, and at a higher temperature, than cheddar. Camembert curd is not cooked at all. The amount of salt added to chesses, whether it is incorporated before or after pressing, the difference in temperature during ripening and intensification of the activity of bacteria, e.g. in Roquefort cheese, all vary for different cheeses.
Great skill, acquired only after long practice based on years of experience, is required for the regularly repeated production of a specific flavour and consistency. These depend, not on one but on several forms of minute microscopic life. For example, in Camembert, the chief biological factors are lactic acid bacteria, the ever-present milk mold, and a foreign Penicillium mold, the blue-green bread mold.
If the lactic acid bacteria are permitted to develop in too great numbers before the curdling, the consistency of true Camembert cannot be attained.
If the Penicillium overcrowds the milk mold the consistency may be good, but the flavour is inferior.
Cheeses are commonly graded as special, fancy, good, prime and common.
