Additives in food are as ubiquitous as they are nebulous. In our PrimaFoodie Ingredients Spotlight, we investigate common food additives to discover their origin, use, and purpose. Because just because something is edible doesn't mean it's healthy—or necessary.

What Is Cellulose?

Every one of us has consumed cellulose. This ubiquitous fiber is both naturally found in plants and an additive in countless foods, from ice cream to bread to veggie burgers. But what exactly is cellulose? Let's dig in.  

Cellulose is a naturally occurring organic insoluble fiber in nearly all plant matter, from cotton and wood to vegetables and fruits. It's a carbon, oxygen, and carbon molecule in plant cells that lends plants structure and support. Cellulose is also extracted from plant sources, processed, bottled, and used as a supplement and food additive. For this article, we'll look solely at cellulose as a food additive.

What's the Purpose of Cellulose?

Cellulose provides food with added bulk, thickness, and texture. Food manufacturers add cellulose to stretch a product's quantity and lend it additional fiber. Because cellulose is relatively tasteless and contains zero calories, it has little impact on a food's flavor or nutritional value. When mixed with water, cellulose forms a gel-like consistency and can, therefore, emulsify certain foods, giving them a satisfying, blended consistency. This is why it's commonly added to ice cream, condiments, sauces, soups, and more. Cheesemakers often add cellulose to their recipes to prevent caking.

Cellulose generally comes in three forms: cellulose gel, cellulose gum, and cellulose powder. The most popular form of cellulose added to processed foods usu­ally comes from wood pulp and cotton lint.

The Various Names of Cellulose

Look at an ingredients list, and you may see 'cellulose' labeled just like that. But chances are, it will lurk behind one of its other names: microcrystalline cellulose (also called MCC) or carboxymethylcellulose.

Where Is Cellulose Found?

Due to this thickening, emulsifying, stretching, and fiber-adding qualities, it's added to countless foods. You can find cellulose in:

Cheeses
Cottage cheese
Yogurt
Ice Cream
Bread and other baked goods
Snacks
Condiments
Soft drinks
Juice
Canned goods
Jared sauce
Gravies

Is Cellulose Harmful?

Researchers have studied additive dietary cellulose and its potential impact on the microbiome and overall gut health. Still, there needs to be more evidence of research on the impact of how food additive cellulose impacts human health. The FDA deems cellulose powder, gum, and gel as 'generally recognized as safe' (GRAS). 

The PrimaFoodie Take

It may not surprise you that we try to avoid cellulose, as much as possible. The FDA may deem it as ‘GRAS,’ but this always makes us pause. Same goes for the word ‘additive.’ Dietary cellulose is just that, an additive. Plus, it’s primarily wood pulp or cotton, and yet another way for food manufacturers to stretch food to increase their profits. Cellulose fills our stomachs, but does not nourish our bodies. 

Simply put, we’ll take our cheese free of wood pulp.
