Have you ever wondered why Parmesan cheese has cellulose in it? While some may think it’s a strange addition to a beloved dairy product, there’s actually a good reason for it.

What is cellulose?

Cellulose is a naturally occurring compound found in plants and is the main component of the cell walls of green plants. It is a complex carbohydrate that provides structure and support to plant cells. Cellulose is also commonly used in many different industries, including food production.

Why is cellulose added to Parmesan cheese?

Parmesan cheese is known for its distinct flavor and texture. However, when it comes to grated Parmesan cheese sold in stores, manufacturers often add cellulose to prevent clumping and improve texture.

The cellulose used in grated Parmesan cheese typically comes from wood pulp or cotton. It is often listed as an ingredient on the label and can account for up to 4% of the product’s weight.

Is cellulose safe to consume?

Yes, cellulose is considered safe for human consumption by regulatory agencies such as the Food and Drug Administration (FDA). In fact, it is commonly used as a filler or bulking agent in many processed foods.

However, some people may be allergic or sensitive to cellulose. If you experience any adverse reactions after consuming products containing cellulose, it’s best to avoid them in the future and consult with a healthcare professional if necessary.


While some may view the addition of cellulose in Parmesan cheese as unnecessary or even concerning, it serves an important purpose in preventing clumping and improving texture. As long as you don’t have any allergies or sensitivities, there’s no need to worry about consuming products containing cellulose.

So next time you enjoy a delicious bowl of pasta with freshly grated Parmesan cheese on top, remember that there’s more to this beloved dairy product than meets the eye.
