Guar Gum and Partially Hydrolyzed Guar Gum

Guar Gum and Partially Hydrolyzed Guar Gum Differences

Guar Gum and Partially Hydrolyzed Guar Gum both come from guar beans. Guar Gum thickens things, and Partially Hydrolyzed Guar Gum is a thinner version made using special stuff.

Guar Gum is an organic substance that is derived from guar beans. It’s extensively used to thicken in a variety of products, including sauces, ice creams, cosmetics, and pharmaceuticals. It does this by absorbing water and expanding thereby making the product more thick to. The most popular is its origin in plants Guar gum is praised because of its effectiveness in changing the texture of a product.

Partially hydrolyzed Guar Gum is, on the contrary, a modified version of Guar Gum. The process that is ‘partially hydrolyzed’ involves breaking down the structure of the gum and making it less effective as a thickener while increasing its lubricity in liquids.

This makes it a great choice for products where a slight change to the texture of the product is required without substantially raising thickness. It is commonly used in drinks and food supplements, this type of product preserves the main advantages of guar gum but alters its texture in a less significant way.

What is Guar Gum?

Guar gum can be described as a substance derived from the guar seeds Cyamopsis Tetragonoloba. It’s most famous for its function for thickening and as a stabilizing agent. It is a powdered form. it is a fine off-white material that is extremely absorbable in water.

When mixed with water it develops a gel-like consistency that makes it a great thickener for various food items like sauces, ice creams, and baked products. Guar gum is also utilized in non-food industries due to its thickening stabilizing and emulsifying qualities. This includes industries such as pharmaceuticals, cosmetics, and textiles.

Guar gum’s ability to alter the texture and consistency of goods without affecting their aroma or flavor makes it an ideal ingredient for both food and industrial settings. Being a plant-based material, Guar gum is a popular ingredient in vegan and vegetarian products.

What is Partially Hydrolyzed Guar Gum?

Partially hydrolyzed Guar Gum (PHGG) can be described as an altered form of Guar Gum, a naturally occurring product derived from Guar beans. The process of modification, also known by the name of partial hydrolysis is the process of dissolving the guar gum’s molecular structure, to a certain extent.

The process decreases the dimensions of the polysaccharide chains. This results in a substance that’s less viscous, and has a lower thickness capacity when compared to normal Guar gum. The main feature the most notable feature of PHGG is its greater solubility in water and its reduced effect of thickening.

This makes it ideal to be used in products where a smoother texture is desired but without any significant growth in viscosity. PHGG is often used in a variety of drinks and food products to improve texture and ensure consistency.

It can also be beneficial in health supplements and dietary products since its high fiber content and low viscosity could aid in digestion and improve the health of your gut without affecting the flavor or texture or flavor of the item.

partially hydrolyzed Guar Gum has the same functional characteristics as regular guar gum but with less power to thicken which makes it suitable for applications in which an ethereal texture is wanted.

Difference Between Guar Gum and Partially Hydrolyzed Guar Gum

Here’s a comparison chart summarizing the key differences between Guar Gum and Partially Hydrolyzed Guar Gum:

Aspect Guar Gum Partially Hydrolyzed Guar Gum (PHGG)
Source Extracted from guar beans Derived from guar gum through partial hydrolysis
Composition Predominantly galactomannan polysaccharides Similar to guar gum but with shorter polysaccharide chains

Solubility Limited solubility in cold water Better solubility in water, easy to mix
Digestibility May cause digestive issues in high amounts Easier to digest, reduced risk of digestive issues
Fiber Content High fiber content, can aid in digestion High fiber content, promotes gut health
Health Benefits Cholesterol management, blood sugar control, digestive health Similar health benefits but gentler on the digestive system
Allergic Reactions Rare allergic reactions are possible Rare allergic reactions are possible
Medication Interaction May interfere with medication absorption May interfere with medication absorption
Common Applications Food, cosmetics, pharmaceuticals, textiles Food, dietary supplements, gut health products
Environmental Impact Conventional agricultural practices may have environmental concerns Similar to guar gum, but processing may have environmental advantages

Composition and Structure of Guar Gum and Partially Hydrolyzed Guar Gum

Guar Gum


  • Guar gum is made up mainly of guaran polysaccharide, an emulsion of galactomannan.
  • It consists of linear chains of (1-4)-b-D-mannopyranose units with a-D-galactopyranose units attached by (1-6) linkages.
  • The proportion of galactose to mannose in guar gum is about 2:1.


  • Guar gum’s structure is a high-molecular-weight carbohydrate polymer that gives it excellent thickening properties.
  • It is a viscous liquid when it is dissolved in water when the polysaccharides are hydrated and expand, thereby making the solution more viscous.
  • The structure is the main reason behind its ability to create hydrogen bonds with water, which results in the use of it for thickening and stabilizing agent in a variety of applications.

Partially Hydrolyzed Guar Gum


  • Partially Hydrolyzed Guar Gum (PHGG). It is made from guar gum by the process called partial hydrolysis. It reduces the polysaccharides’ long chains into shorter chains.
  • The process alters the ratio of galactose and mannose however it retains its chemical name as galactomannan.


  • The partial hydrolysis decreases the molecular mass of guar gum in a significant way.
  • This structural change results in an increase in its capacity to thicken solutions, however, it improves its digestibility and solubility.
  • PHGG is not an extremely viscose solution as unmodified guar is, which makes it suitable for use in areas where less thickness is required, however, the benefits of fiber content and solubility remain.

How is the making of Guar Gum different from Partially Hydrolyzed Guar Gum?

The method by which Guar Gum and Partially Hydrolyzed Guar Gum are made is very different. Guar Gum is constructed by the seeds of the Guar plant. The seeds are then ground into a fine powder, which is known as Guar Gum. It’s as simple as simply crushing the seeds.

Partial Hydrolyzed Guar Gum is made in a similar to process, however, there’s a second step. Once the guar gum has been created, it is subjected to the process of partial hydrolysis.’ This means that it is treated with water and a few special chemicals which break it down little.

It doesn’t change the substance completely however it does make the Guar Gum less dense and able to dissolve when in water. Thus, even though Guar Gum is essentially ground-up guar seeds hydrolyzed Guar Gum is Guar gum that has further been processed to make it less dense.

Health Benefits of Guar Gum vs. Partially Hydrolyzed Guar Gum

Guar Gum

  • Digestive Health: Guar gum is rich in soluble fiber and aids in improving digestion. Guar gum aids in bowel regulation and may be beneficial for people suffering from constipation.
  • Cholesterol Management: Guar gum has been linked to lower levels of cholesterol. The soluble fiber it binds cholesterol in the intestines, assisting in the elimination of cholesterol from your body.
  • Blood Sugar Control: Guar gum is a natural ingredient that slows the absorption of sugar into the intestines, resulting in an increase in the levels of blood sugar. This is particularly beneficial to people suffering from diabetes.
  • Weight management: Gum may create a sense of fullness. This could aid in reducing overall calorie consumption and assist in weight loss.

Partially Hydrolyzed Guar Gum

  • Improved Digestibility: Hydrolysis in part makes this type of gum more easy to digest. This is a benefit to those who have sensitive digestive systems or who have difficulty digesting the high viscosity that regular guar gum has.
  • Gut Health: It is also prebiotic which means that it assists in providing the necessary bacteria to the gut. This may improve the health of your gut and help with digestion.
  • Lower risk of gas: PHGG has less viscosity and is easier to digest, it is much less likely to create gas or gastric bloating when compared to regular gum.
  • Keeps Health Benefits: Despite the hydrolysis process, PHGG still retains many of the health benefits that come with regular gum, like helping in the management of cholesterol as well as blood sugar management.

Is there any side effect of Guar Gum and Partially Hydrolyzed Guar Gum?

Guar Gum:

  • A lot of Guar Gum could cause stomach pain, gas and bloating or cramps because it’s rich in fiber.
  • Sometimes, it can cause obstruction in your stomach or throat in the event that you don’t mix it well with enough water.
  • Certain people may experience breathing or skin problems in the event of an allergy.
  • Additionally, Guar Gum may alter the way the body absorbs drugs when you take these medications at the same time.

Partially Hydrolyzed Guar Gum (PHGG):

  • PHGG is gentle to your stomach because it’s not as heavy and gooey.
  • However, too much will make you feel gassy and bloated.
  • Similar to Guar Gum As with Guar Gum, there’s the possibility of a slight reaction.
  • It can also alter the way certain medicines perform in combination.


Guar Gum is a natural thickening ingredient derived of the plant guar. It is extensively used in cosmetics, food and pharmaceuticals due to its ability to stabilize and thicken products. It’s praised due to its plant-based origins and ability to alter the texture of different products.

Partially hydrolyzed Guar Gum (PHGG) It is a modified form of Guar gum. It is subjected to partial hydrolysis, decreasing its capacity to thicken, but increasing its water solubility.

It is utilized when it is required to have a smoother texture without excessive thickening, for example in food and drinks. It still retains the advantages of Guar gum, but has the ability to have a less noticeable effect on texture.
