What Happens Chemically As Cheeses Are Aged?

French cheese and baguette

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?

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?
