As a lover of cheese and soy sauce, have you ever wondered how they’re made? Surprisingly, mold plays a vital role in creating some of our favorite foods. Mold is a type of fungus that grows in warm and damp environments and can be found in many different foods. In this article, we will explore the science behind mold and food production and discover just how many different foods are created by mold.

The Science Behind Mold and Food Production

Mold has been used in food production for centuries, and for a good reason. It helps break down complex compounds, making them easier for our bodies to digest and absorb. The mold used in food production is entirely safe and is even considered beneficial in some cases.

There are different types of mold used in food production, such as Penicillium roqueforti, which is used to create blue cheese, and Aspergillus oryzae, which is used to make soy sauce. Each mold has a unique flavor and texture, making it ideal for specific types of food.

For mold to grow, it needs specific conditions, including moisture, warmth, and a food source. Foods that are high in moisture, such as fruits and vegetables, are more likely to grow mold than dry foods like crackers and cookies. This is why it’s essential to store food correctly to prevent mold growth.

In conclusion, mold plays a crucial role in food production, and many of our favorite foods are created by it. In the next section, we will explore some of the foods created by mold and discuss their health benefits and risks.

Foods Created by Mold

Mold is responsible for some of the most delicious and unique foods we enjoy today. Here are some of the foods that are created by mold:


Cheese is one of the most popular foods created by mold. Blue cheese, for example, is made by adding Penicillium roqueforti mold spores to the milk during the cheese-making process. The mold produces a distinctive blue color and gives the cheese its characteristic sharp and tangy flavor. Other types of mold used in cheese-making include Penicillium camemberti, which is used to make Camembert and Brie cheese.

Soy Sauce

Soy sauce is a staple condiment in many Asian countries and is made by fermenting soybeans with the mold Aspergillus oryzae. The mold helps break down the soybeans’ proteins and carbohydrates, creating a savory and umami flavor that complements many dishes.

Tempeh is a plant-based protein source made by fermenting soybeans with the mold Rhizopus oligosporus. The mold binds the soybeans together, creating a dense and chewy texture that is high in protein and nutrients.


Quorn is a meat substitute made from the mold Fusarium venenatum. The mold is grown in a controlled environment and is then harvested and processed into various meat substitute products, such as burgers and nuggets.


Some types of sausages, such as salami and pepperoni, are made using mold. The mold helps preserve the meat and gives it a distinctive flavor. However, it’s essential to note that not all sausages contain mold, and it’s important to read the label to ensure safe consumption.

In the next section, we will discuss the health benefits of consuming moldy foods, as well as the potential risks.

Health Benefits of Moldy Foods

While some people may be grossed out by the idea of eating mold, it turns out that many moldy foods are packed with health benefits. Below are some of the benefits you can get from consuming moldy foods.

Probiotic Properties

Many moldy foods, such as cheese and tempeh, are excellent sources of probiotics. Probiotics are live bacteria and yeasts that are beneficial to our health, especially our digestive system. They help promote a healthy balance of gut bacteria and can improve digestion, boost the immune system, and even reduce the risk of some diseases.

High in Protein

Foods such as Quorn, a meat substitute made from fermented mold, are high in protein, making them an excellent choice for vegetarians and vegans. Protein is essential for building and repairing tissues in our body and can help keep us feeling full and satisfied.

Low in Fat and Calories

Moldy foods are often low in fat and calories, making them an excellent choice for those looking to maintain a healthy weight. For example, blue cheese is relatively low in fat compared to other types of cheese, and tempeh is a great low-calorie source of protein.

Rich in Vitamins and Minerals

Moldy foods are also a great source of vitamins and minerals. For example, cheese is a good source of calcium, which is essential for strong bones and teeth. Tempeh is high in iron, which is essential for healthy blood cells, and blue cheese is rich in vitamin K, which is important for blood clotting.

Risks Associated with Consuming Moldy Foods

While moldy foods may have some health benefits, they also come with risks. Eating moldy food can lead to allergic reactions, toxicity, and fungal infections.

Allergic Reactions

Some people are allergic to mold and may experience symptoms such as sneezing, runny nose, and itchy eyes when exposed to it. In severe cases, mold exposure can lead to anaphylaxis, a life-threatening allergic reaction.


Certain types of mold produce mycotoxins, which can be harmful if ingested in large quantities. Mycotoxins can cause a range of symptoms, from mild to severe, including nausea, vomiting, and liver damage.

Fungal Infections

Eating moldy food can also lead to fungal infections, such as aspergillosis or candidiasis. These infections can affect different parts of the body and cause symptoms such as fever, coughing, and difficulty breathing.

To reduce the risk of consuming moldy food, it’s essential to practice proper food storage and handling. Always check the expiration date and inspect food for any signs of mold before consuming it. If you do come into contact with moldy food and experience any symptoms, seek medical attention immediately.

In the next section, we will discuss how to safely consume moldy foods and enjoy their health benefits while minimizing the risks.

How to Safely Consume Moldy Foods

Moldy food can be a health hazard, and it’s essential to know how to identify and handle it. Here are some tips on how to safely consume moldy foods:

Identifying Safe Mold vs. Dangerous Mold

Not all mold is harmful, and some types are even edible. Safe molds include those used to create blue cheese and other fermented foods. However, dangerous molds can cause illness and should be avoided. These include black mold, which can cause respiratory problems, and Aspergillus flavus, which produces aflatoxins that can cause liver damage.
