The History of Cheese
Most experts say that cheese was premier(prenominal) make in the Middle East. The earliest type was a form of sour milk which was made when it was discovered that domestic animals could be milked. A legendary story states that cheese was discovered by an unknown Arab nomad. He is said to have filled a saddlebag with milk to sustain him on a journey crossways the desert by horse. After several hours riding he stopped to quench his thirst, only to find that the milk had separate into pale watery liquid and solid white lumps. Because the saddlebag, which was made from the stomach of a young animal, contained a coagulating enzyme known as chymosin, the milk had been effectively separated into curds and milk milk whey by the conspiracy of the rennin, the hot sun and the galloping motions of the horse. The nomad, unconcerned with technical details, found the whey drinkable and the curds edible (www.goodcookery.com)
Enzymes in Cheese
According to Paul Diehl from in the dairy industry, some enzymes are required for the production of cheeses, yoghourt and early(a) dairy products. Five of the more common types of enzymes and their determination in the dairy industry are rennet, other proteases, lactase, catalase, lipases.
Rennet and rennin are general terms for any enzyme used to clabber milk. Technically rennet is also the term for the lining of a suras fourth stomach the most common enzyme unaffectionate from rennet is chymosin. Chymosin can also be obtained from several other animal, microbial or vegetable sources, but indigenous microbial chymosin (from fungi or bacteria) is ineffective for making cheddar cheese and other hard cheeses.
Milk contains a number of variant types of proteins. Cow milk also contains whey proteins like lactalbumin and lactoglobulin. The denaturing of these whey proteins, using proteases, results in a creamier yogurt product. Destruction of whey proteins is...If you want to get a full essay, order it on our website: Orderessay
