At Mons there is an excellent balance, which has built up over many years. Different strains of bacteria are used as "starter cultures" to produce different varieties of cheese. A strain called Lactococcus lactis ssp. Lactobacillus helveticus will give you Swiss. Then there's aging. With semi-hard cheeses, the length of the aging process will determine the hardness of the cheese and the "sharpness" of its flavor profile.
That's because cheese loses moisture as it ages, hardening the cheese and amplifying the natural flavor of the proteins created by the bacterial cultures. This category is reserved for extra-hard, extremely low-moisture cheeses like Parmesan, Machego and Asiago.
These cheeses are characterized by their pungent saltiness and rich umami flavor profile. Because of their hardness, these cheeses are often grated over dishes like pasta and soup, not sliced. Parmesan is a generic name for the original Parmigiano-Reggiano from Italy. To make this classic cheese, large wheels of freshly curdled milk are first soaked in a salt bath for three months, then aged for at least 24 months, but up to three years.
The cheese forms a thick natural rind that's hard on the teeth but is a great addition to soups and stocks. If you notice little crunchy bits in a well-aged, hard cheese, don't fret. Those aren't hunks of salt, says Wright, but cheese crystals that form as a natural byproduct of the slow-aging process. The crystals themselves don't impart any flavor, but they are a sign that bacteria are doing their work breaking down the lactose and amino acids in the cheese, which will result in a more robust flavor.
As any self-respecting cheese-lover will tell you, processed cheese products like Velveeta and Kraft Singles are not cheese.
These products contain many of the elements of cheese — milk, milkfat, whey protein, salt, lactic acid — but they are not the result of a traditional cheesemaking process or anything resembling it. And then there are other processed cheeses that contain some amount of real cheese plus additives that improve the product's meltability and shelf life. Wright is not impressed by any product that has "made with real cheese" on its package. Feta cheese is a fresh cheese made from sheep's or goat's milk that's brined for at least three months to give it its salty, pickled kick.

What Are the Different Types of Cheese? Cheeses may be categorized by texture, flavor, age, region and a host of other ways. Examples include Gorgonzola and Stilton. Freshly made cheese usually tastes salty and quite bland, as it is the ageing or ripening period that helps develop flavour. As cheese ages, microbes and enzymes break down the casein proteins, changing the texture and intensifying the flavour of the cheese.
Ripening conditions are carefully controlled with different temperatures and humidity levels affecting the rate of ripening, loss of moisture and rind formation. The ripening period can be anything from several days to 2 or more years. As the ripening period increases, the cheese loses more moisture, develops a stronger flavour and becomes harder and more crumbly in texture.
Other techniques that create variations in flavour and texture include the addition of salt and stretching the curd. Salt is an essential ingredient in all cheese. It contributes to the flavour and also has a role in drawing out moisture from the cheese, creating a smoother texture and helping protect it from bacterial contamination. Some varieties of cheese have salt added during processing and some by immersing in a brine solution.
A stringy texture is created in some cheeses by stretching the curd and kneading it in hot water. Chymosin is active at low pH whereas plasmin is active at higher pH, pH optimum ca. For this reason chymosin activity during ripening is highest in Cheshire followed by Cheddar followed by Gouda and is least active in Swiss cheese.
Plasmin has the opposite activity profile. Application of acidity and calcium model of Lawrence and colleagues. The Lawrence model provides an explanation of why Cheshire and similar cheeses are crumbly or easily broken; they have a weak internal protein matrix. This is associated with low pH and calcium content. Cheddar has a higher pH and calcium content and a stronger internal protein matrix.
The previous discussion has clearly identified the importance of pH at whey drainage on the development of cheese type and the requirement to regulate acidity in cheese manufacture. Modelling the grade value of Cheddar Cheese. Readers interesting in learning more about the science behind cheese making may find the article on cheese grading interesting.
The article provides further insights on pH and calcium. Go to the article on modelling the grade value of Cheddar cheese. Using this model readers can use the calculator to predict the grade of Cheddar cheese and if you have access to factory data see how well the calculator performs compared to a commercial grader. Professor Arthur Hill from the University of Guelph in Canada has kindly provided a free On Line Ebook on cheese technology which provides excellent coverage of cheese making.
