Cheese is the curdled milk of milk. The milk may be curdled through direct acidification (if it is acidified by bacteria), or by adding an acid (like lemon juice or vinegar) to the milk while the milk is cooling. A rennet (or coagulant) is then added to solidify the curds into cheese. Other ingredients, like salt, may be added to cheese curds to alter the flavor of the final product..

What happens chemically as cheese ages?
The fats in cheese break down over time into fatty acids. This includes the milk fat in cheese. Many cheese that are aged for an extended period develop a greasy texture and yellow color, this process is known as lipolysis. Lipolysis might also produce a characteristic odor. The unique flavor and odor of cheeses like Limburger and Munster come from lipolysis. Lipolysis continues; eventually, the fats and oils in the cheese will be removed and the cheese will become dry and crumbly..
What happens during ripening of cheese?
Cheese is made by separating the curds and whey. The curd is the cheese body, the whey is what is left behind after the cheese has solidified. The process of getting cheese to the point where it is ready for consumption happens in two phases: ripening, and aging. Ripening refers to when the cheese is actually getting its characteristics. This is the part where the bacterium is doing its thing and the cheese is slowly becoming _______. Aging is when the cheese is at its peak of deliciousness. It’s not really aging per se , but it’s when the cheese is the most ready to be eaten. The curd has done its thing, and is no longer changing..
What is the process of aging cheese called?
The process of aging cheese is called cheese ripening. The process involves: (a) culturing the curd (b) cutting and cooking the curd (c) draining and cooling the cut curd (d) ladling the curd. This is why we call cheese ripening process as culturing and it involves culturing, draining and then culturing again to get rid of lactose and develop acidity in the cheese..
What happens to Cheddar as it ages?
Cheddar cheese is a common food product. It can be found in almost every grocery store. Cheddar cheese is a white type of cheese that is made of cow’s milk. It is named after a town called Cheddar, located in Somerset. Some of the main cheese making markets are Canada, the United States, and the United Kingdom. Cheddar can be part of a breakfast, lunch, or dinner. Cheddar is the most popular type of cheese in the United States and can be used in many meals..
What is cheese chemically?
Cheese is the collection of proteins, fats, and carbohydrates from milk. Its chemical structure is very similar to milk, only the texture is different. In fact, the texture of cheese is determined by the types of milk used to make it. Cheese from goat milk is softer, while cheese from cow milk is firmer..
What is the chemical process of making cheese?
Cheese is a dairy product that is usually made from the milk of cows. The process of making cheese is called cheesemaking, and it is nothing but an intricate relationship between many different variables such as moisture, acidity or salt levels. Cheese is made by curdling the milk, and the curdling process is a kind of coagulation. Therefore, the process of making cheese starts with a chemical reaction called coagulation..
Why is aging cheese a chemical change?
Cheese contains fats which are dispersed micelles. A micelles are particles that are too small to be seen by the naked eye. Micelles are water clusters composed of molecules. Aging cheese changes the natural aggregations of these micelles. The process of aging cheese changes the micelles by changing the form of the cheese. There are different types of cheese, but cheese can be classified as one of three types: fresh, soft and hard. The different types of cheese is determined by the different types of bacteria and molds. Each of these bacteria and molds reacts differently with the natural micelles and the cheese. The natural micelles in cheese, which is also known as fat, can be separated by the use of water. Using water will allow the fat to stay together in one big mass, instead of it being dispersed among each other. As time passes, more water is added to the cheese causing the micelles to get smaller and smaller. This allows the fat to be more dispersed, and in turn changes the texture and smell of the cheese. This is a chemical change in the cheese, and it happens with each piece of cheese..
What are the role of microbes during ripening of cheese?
• If ripening halted, cheese would no longer age or develop flavor. • But since aroma and flavor are desirable components in cheese, ripening is actually encouraged. • If bacteria alone were used to form cheese, bacteria eventually would consume all of the cheese’s nutrients. • Cheese must be inoculated with mold spores, also called acidifying molds (fungi) to break down the protein in the curds. • These mold spores are against the surface of the cheese, which allows the bacterium to grow, too. The mold ripens the cheese, while the bacteria help create aroma and flavor. The formation of molds also helps create the sightly brownish color of cheese..
Is making cheese a chemical or physical change?
Cheese is a chemically altered food. This is because there are small chemical changes the milk undergoes the longer it is held at the right temperature (pH becomes more acidic, fat molecules are broken down). The milk is mostly changed through physical processes like straining the curds, stretching the curds, washing the curds, and adding fat..
What is aged cheese?
Aged cheese is cheese that has been ripened for a long time. The process of ripening cheese makes cheese more flavorful, more pungent, and more durable. Ripening or aging is caused by certain bacteria and fungi which is present in the cheese. They slow down the production of acid in the cheese which normally breaks down protein and fat, making the cheese taste bitter. The process of ripening cheese makes the cheese taste more rich and tangy. The most important thing about aged cheese is that it is not just cheese. It is a multi-dimensional experience. Immature cheese does not produce as many flavor compounds as aged cheese. This is because as it ages, cheese undergoes physical and chemical changes. The water evaporates and sugars and amino acids break down, which gives cheese a more complex flavor. That’s why it is so expensive and desirable..
What are aged soft cheeses?
Aged soft cheeses are soft cheeses that may be white or yellow in color or even orange or brown, whereas hard or semi-soft cheeses are usually yellow or white with a soft texture. The most common varieties of aged soft cheeses are cream cheese, boursin, neufchatel, chevre, goat cheese, ricotta, cottage cheese, quark, and fromage frais. These cheeses are usually soft and spreadable. They can be eaten on their own or used as a substitute for cream cheese or other ingredients in a recipe..
What is the oldest aged cheese?

Can mozzarella be aged?
Mozzarella is a fresh cheese and cannot be aged like cheddar or parmesan. The cheese is made with whole milk, rennet and salt. It is also common to add citric acid, sodium citrate and/or calcium chloride to the cheese for flavor and consistency. Mozzarella will taste best within a few days of being made, and it is best to consume it within a week or so of purchase. After that, it will start to taste a little sour and pungent..
What happens to parmesan as it ages?
When freshly-made, the cheese is soft and easy to grate, but after a year or two, it is harder and doesn’t grate as well. The cheese forms crystals, which give it a grainy texture. Grate the cheese before using it, if there is any concern about the age..
