How Tamarind Gum Powder is Prepared and its Applications?


Tamarind kernel powder is obtained from tamarind seeds, while tamarind gum is obtained from the endosperm of the seeds of tamarind tree. It has application in various industries like food, textile, paper, mining, etc. In food industry, tamarind gum is used as a stabilizer and emulsifier. Molecules present in it get spread easily in water and turns to gluey fluid, when it is heated up in acidic form and forms a thermal resistant solution. 

There are several reputed tamarind seed powder exporter in India, who provide quality range of tamarind seed powder for varied needs. Let us learn more about how tamarind gum powder is prepared and its applications. 

How tamarind gum powder is prepared from its kernel or seeds?
The powder is obtained from seeds of tamarind. Its seeds of different grades are grounded methodically to powder at the same time conserving nutritive properties present in them. The seeds are then decorticated & roasted. The kernel of the seeds is then sorted based on their color for obtaining tamarind kernel powder.

USE OF TAMARIND GUM POWDER IN VARIOUS INDUSTRIES
  • Food Processing Industry – It is used in manufacturing sauces, instant noodles, ice-cream, ketchups, etc. Due to acid and sugar content, tamarind pulp is also used in preparation of variety of food beverages and curries. Its kernel powder makes up for a great viscosifier of addition in pet foods as it has better ability to control viscosities, when added in certain types of solutions.
  • Textile Industry – It is used as textile thickeners and textile sizing purposes. Its thickening property makes it as an excellent thickening agent in textile industries.
  • Mining Industry – It is widely used for mining purposes, due to its brilliant property of soil stabilizer. Its specific areas of application include gas and oil drilling industries.
  • Pharmaceutical Industry – It is used for dissolution improvement and is also assessed for its appropriateness as a carrier to improve dissolution rate of poor water-soluble drug celecoxcib. It is also used to manufacture bio-adhesive tablets.

Carboxymethyl Starch & Guar Slurry for Printing Thickeners

Different types of printing thickeners such as guar slurry, carboxymethyl starch, etc. imparts plasticity and stickiness to the textile print paste, so that they can be easily applied on the surface without spreading and bleeding. They possess the capability of maintaining the design out lines.

They are traditionally made by weighing out and at times, if required dissolving the auxiliary chemicals and colorants. They are then stirred into the required weight of pre-prepared thickener. These printing thickeners are basically viscous and colorless paste made by using one or more thickening agents. The use of different terms such as thin, thickener, long or short is used to describe print pastes as more descriptive rather than scientific.

It is very important for thickeners to be compatible and stable with dyeing auxiliaries and dyes to be used with. Printing thickeners are widely appreciated for purity, effectiveness and longer shelf life. The produced derivatives of different textile printing thickeners is mainly based on tamarind, corn starch, tapioca, guar gum, etc, for various types of fabrics, dyes & textile printing applications.

Thickeners for textile printing are basically adhesive substances useful in making viscose printing pastes in water. They can be classified into: - natural, modified starch, emulsion and synthetic.

Carboxymethyl Starch
It is basically a guar gum derivative and is used as a mobility control agent like water loss control, oil, petroleum industries, friction reducing viscosity control & gas.

Guar Slurry
It has very distinctive property, which makes it appropriate for oil and well drilling. Its properties of water loss control and viscosity makes it suitable as an ideal thickening, suspending and stabilizer agent. It is mainly used for oil drilling processes that includes mud drilling, stimulation and fracturing.
