What Is Cellulose Gum Made from: In-Depth and Comprehensive Understanding

When you search the question “what is cellulose gum made from”, what you are really concerned about is if it’s safe as a common food additive. Here we try to answer this question from its roots.

What Is Cellulose Gum?

The substance in question is a partially-sodium salt form of carboxymethyl ether derived from cellulose extracted from fibrous plants. In 2013, the EU modified the definition and synonyms of E466 Specification to explicitly state that it refers to sodium carboxymethyl cellulose or cellulose gum, while previously it was referred to as carboxymethyl cellulose or cellulose gum with the addition of sodium carboxymethyl cellulose or NaCMC as synonyms.

What is Cellulose Gum Made from: Ingredients & Steps

Sodium carboxymethyl cellulose is made up of an anhydro glucose unit with an average of 0.2-1.5 carboxymethyl groups (-CH₂COOH) attached to it. The manufacturing process involves two main steps: alkalinization and etherification.

During the first step, cellulose pulp is dispersed in an alkali solution, typically sodium hydroxide (5-50%), to produce alkali cellulose. This reaction results in the formation of cellulose sodium salt and water.

In the second step, alkali cellulose is etherified by reacting it with up to 30% sodium mono chloroacetate in an alcohol-water solution. The mixture is heated (50-75°C) and stirred during the process. The reaction between sodium mono chloroacetate and sodium hydroxide results in the formation of sodium chloride and sodium mono chloroacetate. This is followed by the formation of sodium carboxymethyl cellulose through the reaction between alkali cellulose and sodium mono-chloroacetate.

The degree of substitution (DS) of sodium carboxymethyl cellulose can be adjusted by controlling the reaction conditions and the use of organic solvents such as isopropanol.

What are the uses of Cellulose Gum?

Cellulose gum, also known as sodium carboxymethyl cellulose or cellulose gum, has a wide range of applications in various industries.

• Food Applications

One of the primary uses of cellulose gum is in the food industry. Cellulose gum is a food-grade thickener that imparts thickening and creamier characteristics to food. It is used as a thickening, suspending, emulsifying, stabilizing, and film-forming agent in many food products. Cellulose gum can replace other thickeners such as guar gum, gelatin, agar, sodium alginate, and pectin in some food applications.

Following are some of the main uses and functions of cellulose gum in food applications:

• Beverages: Cellulose gum stabilizes particles and improves the mouthfeel of beverages.
• Bakery: Cellulose gum improves the volume and texture of baked goods, retains moisture, and prolongs shelf life.
• Desserts: Cellulose gum retains fluids in hydrocolloid dressings, improves the mouthfeel, and reduces syneresis.
• Dairy: Cellulose gum controls ice crystal growth in ice cream, prevents syneresis, and improves texture.
• Meat: Cellulose gum is used as a water-binding agent and improves yield in meat products.
• Cosmetics

Cellulose gum is also used in the cosmetic and personal care industry. It acts as a binding, emulsion-stabilizing, film-forming, masking, and viscosity-controlling agent in cosmetic and personal care products.

• Toothpaste

Cellulose gum can also be used in toothpaste to enable the liquid and solid raw materials to mix completely and provide toothpaste with proper viscosity, brightness, and smoothness in molding and flowing.

• Other Applications

Apart from food, cosmetics, and toothpaste, cellulose gum is used in various other industries, such as:

• Oil drilling: Cellulose gum is used as a drilling fluid additive to increase viscosity and control fluid loss.
• Detergent: Cellulose gum is used as a thickener and stabilizer in detergent formulations.
• Papermaking: Cellulose gum is used as a coating and binding agent in paper products.
• Textile: The textile industry uses cellulose gum as a sizing and printing thickener.
• Mining: Cellulose gum is used as a flocculating and settling agent in the mining industry.
• Ceramic: The ceramic industry uses cellulose gum as a binder and suspending agent.

Is Cellulose Gum Safe, Any Risks?

Cellulose Gum comes from the cell walls of plants and is also used in toothpaste, pharmaceuticals, and household products due to its thickening and stabilizing properties.

While cellulose gum is generally considered safe, there is still potential for unknown risks as it is not a traditional whole food. Some studies have found that long-term consumption of cellulose gum may promote chronic inflammatory conditions, including colitis, metabolic syndrome, and colon cancer. Additionally, some individuals may be at a higher risk of developing an allergic reaction or sensitivity to the additive that could lead to anaphylactic shock.

Consuming too much cellulose gum can also lead to loose bowel movements and may be used as a laxative for weight loss, but this should always be discussed with a healthcare professional first. Nutrition labels and ingredient lists should be carefully read to avoid confusion regarding the amount of fiber in a food product.
