The idea that cheese is one molecule away from plastic is a common misconception. While it is true that cheese contains many types of molecules, including proteins, fats, carbohydrates, vitamins, and additives, and that its ability to melt and become gooey is due to its chemical composition, water content, and heating process, this does not mean it is one molecule away from becoming plastic. The notion of being one molecule away from something else is misleading, as even one molecular change can result in significant differences in the characteristics of substances. For example, water and hydrogen peroxide only differ by one oxygen molecule but are distinct substances with unique chemical properties.
| Characteristics | Values |
|---|---|
| Cheese being one molecule away from plastic | This is a common misconception. While cheese contains many types of molecules, it cannot be considered plastic unless it can be formed into another shape by melting and cooling. Natural cheese can be permanently deformed by melting and cooling, making it technically more plastic than processed cheese. However, the statement that cheese is one molecule away from plastic is meaningless as many substances share similar chemical properties, but even a single molecule difference can significantly alter their qualities. |
| Cheese absorbing hazardous chemicals when wrapped in plastic | True. Cheese has a high fat content and readily absorbs migrating chemicals from plastic. Chemicals such as benzophenone, vinyl chloride, and DEHA have been observed to migrate from plastic into cheese, posing potential health risks. |
| American cheese being referred to as plastic | Yes, American cheese is often referred to as "plastic cheese" due to its processed nature and unusual texture. However, it does not contain ground-up recycled plastic bottles. |

What You'll Learn
Natural cheese is more plastic than processed cheese
Natural cheese is technically more plastic than processed cheese. Natural cheese can be permanently deformed by melting and cooling, whereas processed cheese cannot. This is because processed cheese contains emulsifiers that bind the cheese's components tightly, preventing separation even with a sudden increase in temperature. However, with prolonged heating at a lower temperature, the components of processed cheese will separate.
The idea that cheese is "one molecule away from plastic" is a common misconception. While it is true that many substances, including cheese, share similar chemical properties with plastic, even a single molecule difference in molecular structure can result in vastly different qualities. For example, water and hydrogen peroxide only differ by an oxygen molecule, yet they have distinct chemical properties. Therefore, while natural cheese may exhibit some plastic-like characteristics, it is not accurate to say that it is "one molecule away from plastic."
Natural cheese contains a variety of molecules, including proteins, fats, carbohydrates, vitamins, and added molecules for shelf life, texture, or flavour enhancement. These molecules contribute to the cheese's ability to melt and become gooey when heated, a characteristic that is often associated with plasticity. However, the presence of multiple molecules means that altering a single molecule would not necessarily transform cheese into plastic.
Processed cheese, on the other hand, is created by blending different varieties of cheese with water and an emulsifier, resulting in a uniform flavour and texture. This process gives processed cheese its characteristic meltability and consistency, which some may associate with the qualities of plastic. However, the presence of emulsifiers in processed cheese prevents it from being permanently deformed, which is a defining characteristic of plastic materials.
In conclusion, while natural cheese may exhibit some plastic-like properties due to its molecular composition and behaviour when heated, it is not accurate to say that it is "one molecule away from plastic." The phrase "one molecule away" oversimplifies the complex differences in molecular structure and resulting qualities between substances. Additionally, processed cheese, despite its reputation for being plastic-like, lacks the permanent deformability that defines plastic materials. Therefore, natural cheese is technically more plastic-like in nature than processed cheese, but both types of cheese are fundamentally distinct from plastic.

Cheez Whiz is not plastic
It is a widely spread urban food myth that Cheez Whiz is one molecule away from plastic. This claim is not supported by any scientific evidence. In fact, the process of making Cheez Whiz involves blending natural cheeses, milk solids, and canola oil heated with an emulsifier, resulting in a uniform flavour and texture.
Cheez Whiz, a product of Kraft Foods, is a commercial cheese spread composed of 47% milk fat. While it may not be considered a fine or artisanal cheese, it was designed to be quick and easy to consume, without the need for slicing or peeling plastic films. The spreadable and meltable nature of Cheez Whiz sets it apart from natural cheeses, but does not indicate a proximity to plastic.
The idea that Cheez Whiz is "one molecule away from plastic" stems from a misconception about the nature of molecules and the process of plasticization. While it is true that heating and forming plastic involves molecular changes, the presence of a single molecule does not define a substance as plastic. Additionally, the concept of being "one molecule away" implies a level of simplicity that is inaccurate in chemistry.
Furthermore, the claim that Cheez Whiz is one molecule away from plastic suggests that it could easily become plastic with minimal changes, which is not the case. While milk can be polymerized into a natural plastic through a specific process, it does not mean that Cheez Whiz, a derivative of milk, is inherently close to becoming plastic.
In conclusion, Cheez Whiz is not plastic, and the statement that it is "one molecule away" is a misleading oversimplification. Cheez Whiz has its own unique chemical composition, and while it may not be considered a traditional cheese, it is a distinct product with specific characteristics that do not align with those of plastic.

American cheese is plastic
While American cheese is not made of plastic, it has been described as plastic due to its texture and composition. The notion that American cheese is "one molecule away from plastic" is a common misconception. This phrase suggests that a slight change in its molecular structure could result in plastic. However, it is important to understand that molecules can vary significantly, and substituting one molecule for another does not necessarily create plastic.
American cheese is a processed cheese product made by melting a mixture of various cheeses, such as cheddar, colby, and Swiss, with liquids and emulsifying agents. This blend is then molded into bricks or slices for mass consumption. The process of melting and molding gives American cheese its characteristic texture, which some people compare to plastic. Additionally, the presence of emulsifying agents contributes to the perception of American cheese as a plastic-like substance.
The term "plastic" in the context of food refers to something that is ""capable of being molded or modeled." In this sense, American cheese can be considered plastic due to its malleable nature. It can be melted and used as a sauce, showcasing its flexibility and adaptability. However, it is important to distinguish between the colloquial use of the word "plastic" and its biochemical definition. Biochemically, plastics are composed of long strands of emulsified hydrocarbons, which are also found in American cheese.
The confusion surrounding the nature of American cheese may also arise from the FDA's definitions of processed cheese products. According to the FDA, pasteurized process cheese food products must be mixed into a "homogeneous plastic mass." Here, the word "plastic" refers to the ability to mold or shape the product rather than its chemical composition. Nevertheless, this terminology can contribute to the perception of American cheese as being akin to plastic.
While American cheese may be likened to plastic in terms of texture and moldability, it is not made of the same synthetic materials as plastic. The phrase "one molecule away from plastic" is an oversimplification that fails to capture the complexity of molecular structures and transformations. American cheese, despite its processed nature and unique characteristics, remains a cheese product with its own distinct properties and attributes.

Plastic-wrapped cheese may expose you to harmful chemicals
The idea that cheese is "one molecule away from plastic" is a common misconception. While it is true that cheese contains many types of molecules, including proteins, fats, carbohydrates, vitamins, and additives, it is not accurate to say that it is only one molecule away from becoming plastic. This statement oversimplifies the complex chemical composition of both cheese and plastic.
However, there is a valid concern regarding the packaging of cheese in plastic, which may expose consumers to harmful chemicals. Plastic is stable but not inert, which means that it can leach chemicals into the food it comes into contact with, especially dairy products like cheese. This process, known as "chemical migration," occurs even at room temperature.
Cheese, with its high fat content, readily absorbs migrating chemicals from plastic packaging. Two commonly used plastics in cheese wrapping are low-density polyethylene (LDPE) and polyvinyl chloride (PVC), both of which contain carcinogens and endocrine disruptors. Studies have found that the chemical benzophenone, linked to cancer and hormone disruption, migrated from LDPE packaging into cheese at various temperatures. PVC is known to leach vinyl chloride, a carcinogen, into food, and it also contains DEHA, a likely endocrine disruptor and carcinogen.
The high levels of DEHA found in cheese are particularly concerning given that cheese is widely consumed, especially by children in individually wrapped slices. The small size and high surface-to-volume ratio of these cheese slices increase the risk of chemical leaching. While humans have been making cheese for thousands of years, the use of plastic wrap is a relatively new phenomenon, and safer alternatives, such as paper wrapping, are available.
It is important to note that the potential health risks of ingesting these chemicals are not fully understood. While some individuals may experience chemical intolerance, the cumulative effects of constant exposure to low levels of these chemicals are challenging to trace. Nevertheless, efforts should be made to limit exposure to these potentially harmful substances, especially in vulnerable populations.

Videos claiming processed cheese is plastic are misleading
Several videos circulating on the internet claim that processed cheese is plastic because it does not melt when exposed to an open flame. However, this is misleading as processed cheese slices, like many "natural" cheeses, are not strictly solid at room temperature, so they will not exhibit a clear change from solid to liquid when heated. Moreover, rapid heating from an open flame can cause molecules to degrade before they have a chance to move apart and flow, resulting in the cheese burning and blackening instead of melting.
While it is true that plastic is a material that can be moulded into a desired shape and retains its shape after cooling, this definition is not exclusive to plastic. Many substances, including natural materials like silk and rubber, exhibit these properties and are not considered plastic. For example, water and hydrogen peroxide are both molecules, but they have very different chemical properties despite only differing by one molecule.
Cheese, whether processed or natural, contains various types of molecules, including proteins, fats, carbohydrates, vitamins, and added ingredients to enhance shelf life or modify texture and flavour. The melting behaviour of cheese is influenced by its chemical composition, water content, and heating process. Processed cheese contains emulsifiers that bind its components tightly, preventing separation with a sudden increase in temperature. However, prolonged heating at lower temperatures can cause the emulsifiers to release their hold, allowing the cheese to melt.
The claim that processed cheese is "one molecule away from plastic" is misleading. While it may share some similar chemical properties with plastic, a single molecule difference can significantly alter the qualities of a substance. Additionally, the term "plastic" in this context is used in a layman's sense and does not accurately reflect the complex chemistry involved in food science.
In conclusion, while processed cheese may have some plastic-like characteristics due to its emulsifiers, it is not accurate to state that it is plastic or one molecule away from becoming plastic. The videos claiming that processed cheese is plastic are based on a simplistic understanding of chemistry and ignore the complex nature of food chemistry and processing.

Frequently asked questions
Cheese is not one molecule away from plastic. While it is true that cheese can be permanently deformed by melting and cooling, this definition of "plastic" is overly simplistic. Many substances, including natural and synthetic materials, can be formed or "plasticized" in this way.
The phrase "one molecule away" is often used to describe substances that share similar chemical properties. However, even small differences in molecular structure can result in significant changes in the qualities of those substances. For example, water and hydrogen peroxide only differ by one oxygen molecule, but they have distinct chemical properties.
American cheese, also known as processed cheese, has been described as "plastic" due to its smooth and uniform consistency. This is achieved by blending various cheeses with emulsifiers like sodium monohydrogen phosphate. While it may fit the broad definition of plastic as a mouldable material, it does not contain actual plastic.
