Types of Cheese

Types of Cheese
The type of cheese produced depends on the milk used and the cheese making process. The milk used may be full fat, semi-skimmed or fully skimmed, this affecting the fat content of the cheese. It may be pasteurised or unpasteurised. Milk from different animals and different breeds is important in determining the final flavour. As well as cow's milk, cheese may be made from sheep or goat's milk. Cheese rennet.

Soft cheeses may be fresh or ripened. Fresh cheeses include quark, cottage cheese and cream cheese. Ripened soft cheeses include Brie and Camembert. Semi-soft cheeses include Stilton, Wensleydale and Gorgonzola. Hard cheeses include Cheddar, Cheshire, and Gruyere. Parmesan is a strongly pressed, very hard, dry cheese ripened for 2-3 years and then grated. Whey cheeses such as Ricotta are made as a by-product of other cheeses from the whey removed during pressing. Processed cheeses are either made with trimmings that are left over from the manufacture of other cheeses, or from dried milk powder. Flavourings, colourings and other additives are used.

Vegetable rennet

Vegetable rennet

Many plants have coagulating properties. Greeks and Romans sometimes used an extract of fig bark to coagulate milk, and in some parts of Greece this tradition continues.[citation needed] Other examples include nettles, thistles, mallow, and Creeping Charlie. Enzymes from thistle or cynara are used in some traditional cheese production in the Mediterranean.

These real vegetable rennets are also suitable for vegetarians. Vegetable rennet might be used in the production of kosher cheeses but nearly all kosher cheeses are produced with either microbial rennet or Genetically Modified rennet. Worldwide, there is no industrial production for vegetable rennet. Commercial so-called vegetable rennets usually contain rennet from the mold Mucor miehei.

Modern Rennet

MODERN RENNET: Until 1990, cheese rennet was produced the old fashioned way (from abomasums), from various "vegetable" rennets (some of which, called microbial coagulant, are made from the microorganism Mucor miehei.) These days, at a cost one tenth of that before 1990, chymosin is produced by genetically engineered bacteria into which the gene for this enzyme has been inserted. When the bacteria are grown in large vats,they secrete rennin, and itis then purified for cheese making. Cheese Rennet is available commercially in tablet or in liquid form. You will find some cheese makers on the web who prefer liquid rennet and disparage the use of rennet tablets. Perhaps, if you are making hundreds of gallons of milk into cheese, buying bulk liquid would make sense, but for making one to ten gallons of milk into cheese, the tablets make sense.

History of Rennet

HISTORY OF CHEESE RENNET: Presumably, the first cheese was produced by accident when the ancients stored milk in a bag made from the stomach of a young goat, sheep or cow. They found that the day-old milk would curdle in the bag (stomach), yielding solid chunks (curds) and liquid (whey). Once they discovered that the curd-chunks could be separated out and dried, they had discovered a means by which milk, an extremely perishable food, could be preserved for later use. The addition of salt was found to preserve these dried curds for long periods of time.
At some point, someone discovered that the most active portion of the young animal's stomach to cause curdling was the abomasum, the last of the four chambers of the stomach of a ruminant animal. (In sequence, the four chambers are rumen, reticulum, omasum and abomasum.) In particular, the abomasum from a suckling kid or calf was especially active. The abomasum was cut it into strips, salted and dried. A small piece would be added to milk in order to turn it into curds and whey.
