What is Guar Gum (E412) in food? Uses, Benefits, Safe and Effects


Table of Contents

Guar gum is a polysaccharide that comes from the endosperm of guar beans. The protein-like polymers form a three dimensional matrix in a water solution, called hydrocolloids. This balanced dispersion prevents separation due to gravity and allows stabilization of emulsions and foams. These are the main characteristics that guarantee thickening (high viscosity) as well as very fine encapsulation of aromas, flavours, and nutrients.

What is Guar gum?

Guar gum is a complex carbohydrate that’s used primarily as a thickener, stabilizer and emulsifier in foods, cosmetics and pharmaceuticals. Guar gum is made from the seed of the guar plant, which is grown mainly in India, Pakistan and the United States.

Guar gum is one of the most versatile food ingredients available due to its ability to thicken liquids without altering their appearance or taste. It can be added to ice cream, ketchup and salad dressings to help prevent them from separating during storage. It’s also used in cosmetics such as facial cleansers and hair conditioners because it helps these products retain moisture better than they would if they were formulated without guar gum.


Like locust bean gum and tara gum, galactomannans also contribute to the large percentage of guar gum; it can thus be chemically described as galactomannans.

Galactomannans are polysaccharides consisting of mannose and galactose with an approximate ratio in guar gum of 2:1, a ratio of 3:1 in tara gum, and a ratio of 4:1 in LBG.

Following is the structure of galactomannans sourced from EFSA.


what is guar gum powder?

Guar gum is a galactomannan gum extracted from leguminous plants. It is a polysaccharide, composed of mannose and galactose monomers. It has a molecular weight of about 1 million daltons (10^6 g/mol).

The guar plant grows in semi-arid regions and can survive long periods of drought. Guar seeds are oily and rich in protein. In ancient times, they were used as food for birds and animals. The seeds were also used as medicine for constipation and stomach pain.

what guar gum made from?

Guar gum is made from the ground endosperm of a legume called Cyamopsis tetragonoloba. It is also known as cluster bean and galactomannan gum. Guar gum is a polysaccharide with many medical and industrial applications.

The plant grows in India, Pakistan, Mexico, China, Argentina and Australia. The seeds are extracted from the pods of the plant and then dried. After that they are milled into powder form before they are sold as a food additive or industrial product.

Guar gum has been used for centuries in India as a food thickener and stabilizer. In fact, it was one of the first gums to be used commercially in 1914 when it was used to make ice cream more elastic so that it could be easily scooped out of containers without melting on the way out. These days guar gum is added to many processed foods like cookies, cakes and candies to replace wheat gluten which can cause digestive issues in people who are sensitive to gluten.

Guar gum also has many medical uses including lowering blood cholesterol levels by preventing bile acid absorption from your intestines.

How is Guar gum made?

The seeds of the guar plant are used to make guar gum. The seed coats are removed from raw guar beans, and then they are ground into a fine powder. This is done using either mechanical or chemical processes.

Guar gum can be produced commercially or on a smaller scale at home. Commercial producers use large machines to extract the starch from guar beans and make it into a gel-like substance. Smaller-scale producers use blenders, food processors, and other kitchen tools to grind raw beans with water until they form a paste.

At this point, you may be wondering how to make your own guar gum at home. While it’s not necessary if you have access to large commercial producers who sell their products online or in stores, there are some benefits of doing so:

You can avoid many common allergens (including gluten) by making your own gum at home with organic ingredients.

how much guar gum to use?

Guar gum is a natural powder that comes from the guar bean. It’s used as a thickening agent in many foods and drinks, and it’s also used as a binder in cosmetics. Guar gum has a high fiber content, which makes it useful for binding foods and cosmetics together.

For use in food recipes, you can replace xanthan gum with guar gum at a ratio of 1:2.

Guar gum is most often found in products that require thickening or texturizing effects. For example, ice cream makers often use guar gum to make their frozen desserts more creamy and smooth. Guar gum also adds structure to baked goods such as breads and cookies, giving them better mouthfeel.

It also works well for adding body to sauces and puddings; just add a teaspoon or two of guar gum to your favorite recipe and you’ll see how quickly it works its magic!

what guar gum used for?

Guar gum is a thickening agent that is used in food, cosmetics, and industrial applications.

Guar gum is extracted from the seed coat of guar beans, a legume native to South Asia and grown widely in India, Pakistan, and Mexico. The seeds contain about 12% protein and 50% starch. Guar gum can be extracted from the whole seed or from just the endosperm of the seed.

Guar gum has been used for centuries in India as a thickening agent for drinks and cooking. Guar gum is also used as a laxative to relieve constipation and to treat irritable bowel syndrome (IBS). In addition to its use as a food additive and laxative, guar gum is also used as an emulsifier in ice cream and other foods.

how much guar gum in ice cream?

The answer is 0.1%. The Guar Gum content of ice cream is 0.1%. The percentage of Guar Gum in ice cream is 0.0001%. The amount of Guar Gum in Ice Cream is very low and does not have any effect on the taste or flavor of the food.

It’s used as an emulsifier and stabilizer in many foods including ice cream, yogurt, salad dressing and sauces/condiments like ketchup and mayonnaise (to thicken them). It can also act as an emulsifier for oils which means that it helps keep oil droplets suspended within water-based liquids like water-based paints or even toothpaste!

what is guar gum in coconut milk?

Guar gum is a water-soluble fiber that comes from the seeds of the guar plant. It’s used to thicken foods and drinks, including coconut milk.

Guar gum is used in many commercial products, including ice cream, salad dressing, sauces and baby formulas. Its ability to thicken liquids makes it useful as a thickener in gluten-free baked goods.

Guar gum can be found in some beverages made with coconut milk, such as chai tea and chocolate milk. It’s also used in many other foods and beverages, such as ice cream and salad dressing.

Types of Guar gum

There are three types of guar gum: a common type and clarified guar gum, which is the least processed, and partially hydrolyzed guar gum, which is partially hydrolysed by either heat treatment, mild acid or alkaline oxidative treatment is used for viscosity adjustment.

  • In water: soluble in cold and hot water.
  • In organic solvent: insoluble in ethanol, practically insoluble in organic solvents like oils, greases, hydrocarbons, ketones and esters.


Guar gum can be dispersed in cold or hot water to form a highly viscous solution. after being dispersed in cold water for about two hours, the polymer exhibits a strong viscosity that increases gradually. The highest level of viscosity is reached in about 24 hours.

Its thickening ability is 5 to 8 times that of cornstarch (another common hydrocolloid), and the highest viscosity is quickly reached by heating. Like other hydrocolloids, the viscosity of guar gum depends on time, temperature, concentration, particle size of powder, pH and ionic strength as well as agitation.


Generally, a solution’s viscosity increases as the temperature drops. However, in most cases, solutions of guar gum were more viscous when prepared with cold water than when prepared with hot water.  The viscosity of 0.5% (w/w) guar solutions at 25°C exceed that of 37°C.


Gum arabic is a natural gum with the highest viscosity among all gums. A 1% aqueous solution of gum arabic shows very high viscosity even at very low concentration, with a viscosity of 4 to 5 Pa·s. It is therefore recommended to use it at below 1% concentration in most food applications.


It has a non-ionic property, which makes it stable over pH range of about 1.0–10.5.

Its solution is neutral. The viscosity of a liquid varies with its pH.

PH Value  Viscosity
3.5 or less Increase
3.5 to 6 Decrease following with the pH goes down
6 to 8 Reach the highest
10 or more Go down quickly


Guar gum, when combined with xanthan gum, gum tragacanth and karaya gum, shows viscosity synergy.

Gelling agent

Sodium borate is not self-gelling but can form a gel with small amounts added to its aqueous solution.

People with diabetes often use guar gum because it slows down the absorption of glucose into the bloodstream after meals. The FDA has approved this use for diets requiring low-calorie intake such as Nutrisystem® or Weight Watchers®. Guar gum may also help lower cholesterol levels by binding with bile acids in the small intestine before they are absorbed by your body.


Guar gum is a hydrocolloid (a gelling agent) used in food, such as ice cream and frozen desserts, baked products, dairy products, beverages and more. It has a number of advantages over other hydrocolloids, including its water-retention ability, dietary fiber content, calorie reduction potential and ability to improve ice crystal formation during freezing while also regulating the rheological properties of whatever it’s added to.

Ice cream

Guar gum is used in ice cream manufacturing as a binder and stabilizer. Its property of rapid hydration in cold water makes it outstanding as an ice cream stabilizer, especially when used in high temperature, short-time processes (e.g., 80°C for 20–30 seconds). Guar gum can produce good quality ice cream using 0.2% of guar gum.
