Parmesan cheese is a popular Italian cheese, which is made from cow's milk. This cheese has a unique flavor profile and is commonly used in various Italian dishes. One of the characteristics that make Parmesan cheese stand out is the presence of crystals that form within the cheese as it ages. These crystals, also known as tyrosine crystals, are a hallmark of high-quality Parmesan cheese.
The formation of crystals in Parmesan cheese is a natural process that occurs during the aging of the cheese. As the cheese ages, the moisture in the cheese gradually evaporates, leaving behind concentrated proteins and fats. The proteins in Parmesan cheese are composed of amino acids, including tyrosine. Over time, the tyrosine molecules bind together, forming small, crunchy crystals that give the cheese a unique texture.
The crystals in Parmesan cheese can range in size from small, sand-like granules to larger, crunchy pieces. They are usually found in the interior of the cheese and are visible as small white spots or specks. The size and distribution of the crystals in Parmesan cheese can vary depending on the age of the cheese and the specific conditions under which it was aged.
The presence of crystals in Parmesan cheese is generally considered a sign of high quality. The crystals are an indication that the cheese has been properly aged and that the flavors have had time to develop fully. In addition to adding texture to the cheese, the crystals also contribute to its complex flavor profile. When the cheese is eaten, the crystals release small bursts of intense, nutty flavor that complement the creamy, salty taste of the cheese.
The formation of crystals is not unique to Parmesan cheese. Many other types of aged cheeses, such as aged cheddar, Gouda, and Asiago, also develop crystals as they age. However, Parmesan cheese is particularly known for its distinctive crystal formation and is often used as a benchmark for other cheeses.
When it comes to purchasing Parmesan cheese, the presence of crystals can be an indicator of quality. However, it's important to note that not all Parmesan cheese will have crystals, and the presence of crystals alone is not a guarantee of quality. Factors such as the age of the cheese, the specific conditions under which it was aged, and the quality of the milk used to make the cheese can all have an impact on the final product.
In conclusion, the crystals in Parmesan cheese are a natural occurrence that happens during the aging process. They are composed of tyrosine molecules that bind together over time to form small, crunchy crystals that add texture and flavor to the cheese. While the presence of crystals can be a sign of high-quality Parmesan cheese, it's important to consider other factors when selecting a cheese, such as age and milk quality. Whether you're using Parmesan cheese in a classic Italian dish or enjoying it on its own, the crystals in the cheese are sure to enhance the overall flavor and experience.

The crystals in Parmesan cheese can range in size from small, sand-like granules to larger, crunchy pieces.
Are cheese crystals healthy? ›
There are many kinds of cheese-crystals, but the two most common ones are formed by 'calcium lactate' and 'tyrosine'. Both these crystals are the result of bacterial activity, but they're not at all dangerous.
What are the little crystals in cheese? ›
These crystals are the calcium salt of lactic acid. As cheese ages, the culture breaks down the lactose in the cheese and produces lactic acid. As lactic acid levels rise in the cheese they can begin to bind with calcium ions forming calcium lactate.
What causes calcium crystals in cheese? ›
Accelerated by temperature abuse, excessive residual lactose in the cheese and moisture accumulation within the package, calcium lactate crystal formation is often seen in products where the packaging is loose along a rough surface or cut edge. The moisture phase in cheese contains both calcium and lactate.
What are the white blobs on Parmesan? ›
During the aging process, bacteria break down the lactose in the cheese into lactic acid. That lactic acid combines with the calcium present in the aging cheese to form crystals. These tend to appear on the surface of cheese, where moisture can collect.
What is the crunchy stuff in Parmesan? ›
These crunchy pieces are often mistaken for flakes of salt or taken as a sign that the cheese is drying out, but they are actually little bits of the amino acid tyrosine, and they appear in the cheese as a result of aging. Casein, the main protein in milk, is composed of several amino acids, including tyrosine.
What is the most unhealthy cheese? ›
Although extremely tasty on that cheese plate, soft cheeses such as Camembert, brie and triple-crème (cheese enriched with cream) fall into the “less healthy” category because of their saturated fat content.
What cheese has the most crystals? ›
Hard cheeses where cheese crystals are common and valued include comté, aged cheddar, grana cheeses like Parmesan, Grana Padano, and pecorino romano, as well as old gouda.
Is it safe to eat crystalized cheese? ›
They're most likely calcium lactate crystals, also known as “cheese crystals.” They are completely safe to eat, and usually signify that a cheese is flavorful and well-aged. Calcium lactate crystals form naturally during the aging process and are most commonly found in aged cheddars, including Smoked Medium Cheddar.
Is a little mold on cheese ok? ›
Discard any soft cheese showing mold. For hard cheese, such as Cheddar, cut off at least 1-inch around and below the mold spot (keep the knife out of the mold itself). After trimming off the mold, the remaining cheese should be safe to eat.
The "black spot defect" found in cheddar cheese is produced by bismuth 3 sulfide and has been linked to the presence of bismuth subnitrate in the milk (Lay et al., 2007) .
Are calcium lactate crystals good for you? ›
Calcium is necessary for many normal functions of your body, especially bone formation and maintenance. Calcium can also bind to other minerals (such as phosphate) and aid in their removal from the body. Calcium lactate is used to prevent and to treat calcium deficiencies.
Can you get hypercalcemia from eating too much cheese? ›
Hypercalcemia is not caused by drinking too much milk or by eating too many dairy products.
Is calcium lactate good for you? ›
Calcium lactate is sometimes added to calcium supplements, which may help improve bone strength, oral health, and blood pressure, as well as perhaps even lower the risk of colon cancer in people unable to get enough of this mineral through their diet alone.
What are the circles in Parmesan cheese? ›
You may notice, especially in Swiss and Parm types aged over one year, white specks or crystallized patches. These are amino acid clusters, not mold, and add a pleasant crunch and savory bite to the cheeses' texture.
What do they put in Parmesan cheese to keep it from clumping? ›
In the dairy industry, cellulose is used mainly as an anti-caking agent that ensures shredded cheese will “flow and not clump into a ball,” when it's coming out of a shaker. To make the additive, the raw fiber is chemically treated until it's refined to a microcrystalline powder or reconstituted as gum.
What are the black specks in Parmesan cheese? ›
Black spot defect is known as a fatal flaw in cheese making. These minute flecks of black in aged cheeses mean serious devaluation of cheese. They are formed because of the metallic nature of compounds that find their way into the milk line. The likely cause is poor removal of internal teat sealants.
