You may have seen, read about, or eaten sodium carboxymethyl cellulose (sodium CMC), in the ingredients list of a variety of foods like chocolate milk, waffles, salad dressing, ice cream and more. In fact, it’s used in a wide range of foods and beverages to deliver everything from consistency to texture and more. But just what is cellulose gum? How does it work? And more importantly is cellulose safe to eat?

What is cellulose gum?

 

Cellulose gum, also known as carboxymethyl cellulose (CMC) or methyl cellulose (MC), is a non-digestible fiber produced from natural cellulose. It is used as a food additive, dietary supplement and thickening agent. Cellulose gum is also used in cosmetics and pharmaceuticals.

Cellulose gum is usually made by treating purified plant fiber with aqueous sodium hydroxide (caustic soda) to remove lignin followed by treatment with an organic solvent such as acetone (an organic compound with formula C 3 H 6 O) or ethanol to remove the lignin permanently. The resulting viscous solution is dried to produce a white powdered solid.

The major application for cellulose gum is as an emulsifier and stabilizer in food products such as ice cream, salad dressing, peanut butter, baked goods, confectionery products and frozen desserts. In addition to this primary function, cellulose gum can be used as a thickener or binder in pharmaceutical tablets and capsules to help improve flow characteristics during manufacturing operations and reduce the incidence of tablet breakage during handling prior to packaging.

What is cellulose gum used for?

 

Cellulose gum is a natural product made from wood pulp. It is used as a thickener, stabilizer and emulsifier.

Cellulose gum is used in the production of ice cream, yogurt, margarine, cottage cheese, salad dressing and other foods. It is also used in cosmetics and toothpaste to improve texture, consistency and stability.

It can be found in many common products like coffee creamer, non-dairy creamers, salad dressings and ice cream. Cellulose gum is also used in some medications such as chewable tablets and liquid supplements because it helps prevent them from sticking together during processing into tablets or capsules.

What is cellulose gum in food?

 

Cellulose gum is a tasteless and odorless powder made from wood pulp. It’s used to improve the texture of foods, act as a thickener and emulsifier, and ensure that ingredients are evenly distributed throughout the product.

Cellulose gum is used in frozen fruit bars, ice cream, salad dressings, sauces and ketchup to keep the ingredients from separating while they’re being processed or stored. It also helps prevent sugar crystals from forming on candies like gummy bears.

Food manufacturers use cellulose gum because it doesn’t change the taste or texture of food — it just makes it better.

What is cellulose gum made of?

 

Cellulose gum is a type of fiber that consists of natural plant fibers. It is made from wood pulp and used as a thickening agent, stabilizer and emulsifier. It has been used in foods since the 1950s and is considered safe for consumption.

Cellulose Gum is most commonly found in ice cream, breads, salad dressings, peanut butter and other processed foods which require thickening agents to create a smooth texture. Cellulose gum is also used in cosmetics such as toothpaste and shampoo because it helps these products form suds when added to water.

How is it made?

 

Alkalinization and etherification are the two steps in the manufacturing process of sodium carboxymethyl cellulose.

Step 1: Alkalinization

 

Alkali cellulose is obtained by dispersing the raw material cellulose pulp in an alkali solution (generally sodium hydroxide, 5–50%).

Cell-OH+NaOH →Cell·O-Na+ +H2O

Step 2: Etherification

 

Alkali cellulose is etherified with sodium monochloroacetate in an alcohol-water solution to a maximum of 30%. During the reaction, alkali cellulose and reagent are heated (50–75°C) and stirred.

  1. ClCH2COOH+NaOH→ClCH2COONa+H2O
  2. Cell·O-Na+ +ClCH2COO- →Cell-OCH2COO-Na

In addition to the reaction conditions, the use of organic solvents (such as isopropanol) can influence DS.

Molecular WeightThe degree of polymerisation is approximately 100 (higher than approximately 17000).

Properties

 
  • Degree Of Substitution
  • Solubility
  • Viscosity

Appearance

 

Powder that is slightly hygroscopic, white, yellowish or greyish, odourless and tasteless, granular or fibrous, and slightly hygroscopic.

Degree of Substitution

 

In addition to DS, it measures the number of hydroxyl groups that are substituted per glucopyranose molecule. A complete substitution would result in a DS of 3.

The EU specifies that food grade cellulose gum has a carboxymethyl group content of 0.2-1.5 per unit of anhydroglucose (CH2COOH).

Solubility

 

In water

 

Viscose colloidal solutions are produced by water. The solubility of cellulose gum in water is good, and it absorbs water easily. In hot or cold water, it forms a colloidal solution.

There are two main factors that affect its water solubility: The degree of substitution (DS) and the viscosity of the solution.

Generally, the viscosity ranges between 25 and 50,000 mPa.s, and it is only soluble in alkali when the DS value is 0.33. A higher DS value makes it water-soluble, while a higher DS value makes it less water-soluble.

Increasing the DS value will increase the transparency of its solution.

In organic solvents

 

Benzene, chloroform, copper, methanol, and ethanol are not soluble in organic solvents.

Viscosity

 

The viscosity of its solution is generally related to the degree of polymerization of cellulose (DP), the concentration of the solution, the pH value, the temperature, and the degree of substitution.

1. DP

It depends on where the cellulolytic material comes from.

2. Concentration

Viscosity increases as the concentration of the solution increases.

3. PH

When the pH ranges between 6.5 and 9.0, the viscosity of the 1% sodium CMC solution reaches its highest level. When the PH value changes from 9.0-11.0, the viscosity does not change much.

Once PH9 is reached, viscosity drops rapidly and CMC begins to form, initially the decrease is slow, but once PH>11.5 is reached, the decreasing process accelerates.

4. Temperature

When the temperature increases, the viscosity decreases, but when it cools down, it increases. When the temperature rises to a certain level, a permanent flow reducer will occur. Generally, the higher the degree of substitution, the lower the temperature’s effect on viscosity.

What are the application of cellulose gum?

 

Food

 

As a thickener in our daily food, cellulose gum is used as a food grade product. Food with thickened and creamier taste is more appealing to consumers than food without it.

As a thickener, suspending agent, emulsifying agent, stabilizing agent, and film-forming agent, it is used in beverages, bakery, dairy, desserts, and meat products.

Additionally, it can replace some other thickeners, such as guar gum, gelatin, agar and sodium alginate in some food applications. There are a variety of applications depending on the viscosity and mesh size.

The main functions and uses of this device are as follows:

  • Stabilizes particles and improves mouthfeel in beverages.
  • Improve volume, texture, and moisture retention in the bakery.
  • Desserts: retain fluids in hydrocolloid dressings and improve mouthfeel.
  • In dairy products, ice crystals are controlled, syneresis is prevented, and texture is improved.
  • In meat, water binding improved.

Cosmetics

 

According to the European Commission’s web-based database of cosmetic ingredients, cellulose gum contributes to cosmetic and personal care products by binding, stabilizing emulsions, forming films, masking and controlling viscosities.

Toothpaste

 

To achieve a proper viscosity, brightness, and smoothness in molding and flowing, it allows liquid and solid raw materials to mix completely.

Others

 

Other uses include oil drilling, detergents, paper making, textiles, mining, ceramics, etc.
