Carboxymethylcellulose in Food: Everything You Need to Know About

Carboxymethylcellulose in food refers to its use as a binder, to thicken, to limit crystal development, to absorb and hold water, to thicken, to produce desirable texture or body, and to increase shelf life. The preparation of dry pet foods that produce their own gravy when warm water is added accounts for the majority of its volume utilization.

Carboxymethylcellulose (CMC), another name for cellulose gum, is essentially a thickening ingredient used in a variety of food products. You've probably never heard of it. However, the majority of people regularly consume it.

In essence, CMC is a derivative of cellulose that has carboxymethyl groups linked to the hydroxyl groups of a substance called glucopyranose. These comprise the cellulose backbone's building blocks. Their preparation process is difficult and requires a lot of supplies to accomplish the goal.

There are numerous ways that carboxymethylcellulose in food can perform. Food additives like cellulose gum are frequently used in low-fat and diet products to give them a creamier, thicker consistency that increases consumer appeal. Additionally, some foods and fruits' shelf lives may be increased with the aid of cellulose gum.

This kind of addition, according to the Center for Science in the Public Interest (CSPI), can enhance texture, stabilize foam, prevent sugar from crystallizing, bind water, and do many other things. Because of these benefits, producers routinely use cellulose gum in a variety of meals.

Source of carboxymethylcellulose

Jansen made the initial discovery of CMC following the First World War. It was achieved by reacting mono-chloroacetic acid or its sodium salt with an organic solvent, such as a hydroxyl group substituent, in an alkaline medium.

CMC began while World War II was coming to an end. It is derived from cellulose, a straightforward sugar-based polymer found in plant sources. For the production of carboxymethyl cellulose in commercial quantities, there are two steps in the process.

The suspension of cellulose in an alkaline media. The suspension causes the cellulose chains to break free, allowing the water to enter. By interacting with sodium mono-chloroacetate after the suspension, the cellulose can produce sodium carboxymethyl cellulose.

Side effects of carboxymethylcellulose in food

Cellulose and an acetic acid derivative react to create CMC, a thickening agent. Although it has long been regarded as secure, a 2015 study supported by the National Institutes of Health cast some doubt on that notion. It was shown that CMC impacted gut bacteria, brought on symptoms of inflammatory bowel disease, and caused other changes in the gut, along with obesity and metabolic syndrome, a group of risk factors for diseases associated with obesity.

Early animal investigations also demonstrated that repeated nasal exposure led to mild to moderate inflammation four weeks later. More worrisome was reported that started to surface linking CMC usage to intestinal inflammation. CMC led to "massive bacterial overgrowth" and small intestinal inflammation in immune-compromised mice.

Increased inflammation, blood sugar dysregulation, obesity, and colitis were discovered in later studies using low dosages of carboxymethyl cellulose in mice.

Studies on mice have revealed that ingesting CMC also has a deleterious impact on behavior. Similar to prior studies, CMC cellulose was discovered to worsen gut flora, increase obesity, and cause intestinal inflammation. However, they also discovered modifications in male mice's anxiety behaviors, along with a decline in females' sociability.

Benefits of carboxymethylcellulose

Plant cell walls, such as those in cotton seeds and wood pulp, are the source of cellulose gum. Without adding fat, it is used to thicken and creamy meals. Selecting meals with an ingredient like cellulose gum may help you feel less starved if you're attempting to cut your fat intake or are on a low-fat diet.

Additionally, cellulose gum might aid with appetite suppression. Foods that include cellulose gum fiber tend to make you feel full longer because of this. It is frequently included in diet foods for this additional reason. Due to the high fiber content of cellulose gum, one disadvantage is that eating too many foods high in this substance may cause loose stools. Even some people take it as a laxative to lose weight.

But keep in mind that before utilizing cellulose gum for this function, you should always see a healthcare provider. They can assist you in developing the ideal strategy for you.
