What is gum arabic?

 

Gum arabic definition

 

Gum arabic is a natural gum, obtained from the acacia tree. It is a polysaccharide made up of galactose sugars and rhamnose sugars. It is often used as a food additive, emulsifier and stabilizer, especially in soft drinks.

Composition

 

Sodium alginate is a viscous substance consisting mainly of high-molecular-weight polysaccharides and their calcium, magnesium, and potassium salts.

The main components of gum arabic are polysaccharides and glycoproteins. Arabinogalactan makes up about 90% of the gum, while arabinogalactan-protein makes up about 10%.

The main monomeric units in polymer when hydrolysis and their percentages are as follows:

  1. D-galactose(32.5–35.0%)
  2. L-arabinose (31.7–53.1%)
  3. L-rhamnose (2.7–16.3%),
  4. D-glucuronic acid (5.3–14.0%)
  5. 4-O-methyl-glucuronic acid (0.8–5.2%)
  6. Protein (1.5-3.0%)

Structure

 

It is a highly branched three-dimensional structure consisting of a b-1,3-linked D-galactose core with extensive branching through 3- and 6-linked galactose and 3-linked arabinose.

Two grades of gum arabic

 

Arabic gum is usually divided into two types based on the two tree sources: acacia senegal (hashab grade) and acacia seyal (talha grade).

Hashab grade gum arabic is produced from the bark of the acacia senegal tree. The raw gum is harvested in spring when the sap rises and flows from incisions made in the trunk of the tree. This process allows more water to enter into the tree, causing it to swell and thus making it easier for people to scrape off the bark without harming the plant itself.

Acacia senegal gum has a high quality with a light color and fine texture. It has no odor, is not sticky when wet, does not easily dissolve in water and can be mixed with other materials without affecting their properties.

What is gum arabic powder?

 

Gum arabic powder is a natural gum extracted from the bark of the acacia tree. It is used in many food products, confectionery and pharmaceuticals.

Gum arabic powder is also known as gum acacia or acacia gum. It’s a soluble fiber that acts as a thickening agent in foods and beverages. Gum arabic powder is also used to stabilize emulsions such as mayonnaise and salad dressings, prevent ice crystals from forming in frozen desserts and help prevent bread from rising while baking.

Gum arabic powder has been used since ancient times as a food additive and thickener in the Middle East and North Africa. It’s also used in parts of Asia, where it’s called Arabic gum or Chicle (the Mayan word for chewing gum)

What gum arabic used for?

 

Gum arabic is used as a thickening agent, emulsifier and stabilizing agent in foods such as ice cream, candy and baked goods. It prevents sugar crystallization and improves texture.

Gum arabic helps maintain moisture content in fruits and vegetables during freezing or drying by forming a protective layer around them. It also helps stabilize foam when adding whipped cream to hot beverages or desserts.

Gum arabic is used as an emulsifier in lotions, hair products, toothpaste and other personal care items to help keep oil and water components blended together.

In photography, gum arabic acts as an anti-fogging agent for negatives, helping them dry quickly after processing so they can be exposed to light again immediately for printing or viewing purposes.

How does gum arabic work?

 

Gum arabic is a natural gum made from the hardened sap of various species of the acacia tree. It’s used as a thickener and stabilizer in food, and as an adhesive for paper and cloth.

Gum arabic is a complex mixture of polysaccharides that contains glucose, galactose and rhamnose sugars. The individual sugars are linked together by glycosidic bonds to form large, branched chains. These chains have many hydroxyl groups on them, which are reactive with other molecules.

When mixed with water, gum arabic forms a weak solution called a colloidal dispersion — this means that the gum particles remain suspended in solution without dissolving completely. This allows them to be used as thickeners or emulsifiers in foods such as ice cream or salad dressing.

The hydroxyl groups on gum arabic are also able to react with proteins in foods such as egg whites or milk to form complexes called gums. These gums help stabilize these foods so they don’t separate into their various components during processing or storage (for example, cooking eggs).

Four forms of gum arabic

 

Gum arabic can be classified into four forms according to the degree of the manufacturing process: raw material, middle, powdered, and spray-dried.

1. Raw gum arabic

 

Raw gum arabic is a natural product obtained through manual treatment of the lumps, In food applications, it is mainly used for confectionery and wine.

2. Kibbled acacia gum

 

Kibbled acacia gum is ground acacia gum that has been pulverized into small granules to improve its flowability. The wood and bark particles and other foreign materials can be removed from kibbled gum after it has been ground. It is traditionally used in confectioneries as an acacia gum substitute.

3. Powdered acacia gum

 

Powdered acacia gum is a fine powder produced by grinding kibbled acacia gum, which resembles flour. Powdered acacia gum is used as a coating on candies in confectionery production; and in pharmaceutical applications requiring special powder density for pills.

4. Spray-dried Acacia gum

 

Acacia gum is a pure form of the gum. It is used most often in food products, but it can also be used as an adhesive and in pharmaceutical formulations.

How is it made of?

 

Acacia gum is the product of a bacterial or fungal infection on an Acacia tree, typically a wild tree, but also cultivated gardens. A combination of drought, heat, and poor nutrition stimulates unhealthy trees to create this gum.

The following are the steps in the manufacturing process of gum arabic powder.

Tapping

Farmers in West and South Sudan tap the two species of arabic trees, acacia senegal and acacia seyal, during autumn. Their process involves cutting small holes in the bark so that glue-like sap can seep out.

Collection

The gum arabic nodules are dried in the sun for a few days to make them ready for use.

Manual cleaning

The dried gum is then cleaned by hand to remove bark fibers and other impurities.

Dry purification processing

To remove vegetable and mineral impurities, a process called kibbling, sieving, and pulverization is used.

Aqueous solution purification

It is much more efficient to do this. Dissolve the gum in water and pass it through a series of filters to remove impurities.

Dry

The most common method of producing acacia gum today is spray drying, which can retain all the properties of the raw gum. Roller drying (also known as drum drying) reduces its emulsifying properties by exposing it to drastic thermal treatment.

Acacia gum can be concentrated by either roller drying or spray drying. However, the latter method is more common. It can produce acacia gum that has less water content than acacia gum produced by roller drying (less than 10% loss on dry basis versus 15% loss on dry basis).
