The most commonly used hydrocolloids in the food production industry include; cassia gum,sesbania gum, tamarind gum, guar gum, fenugreek gum, gelatin, Arabic gum et cetera. A prime example of this is starch. Starch cannot form a gel in cold water but on heating, it swells, burst and occupies more space creating greater interaction with and immobilization of water.

For example, Konjac mannan gel, which has been commonly eaten in Asian countries to enjoy the special texture, recently gathers a lot of interest because of its effectiveness of prebiotics. Many hydrocolloids are derived from natural sources. For example, agar-agar and carrageenan are extracted from seaweed, gelatin is produced by hydrolysis of proteins of mammalian and fish origins, and pectin is extracted from citrus peel and apple pomace. Hydrocolloids are among the most commonly used ingredients in the food industry.

General Overview of Food Hydrocolloids 1.1 Introduction to the World of Hydrocolloids The term ‘hydrocolloid’ is derived from the Greek hydro ‘water’ and kolla ‘glue’. Hydrocolloids are colloidal substances with an afﬁnity for water. From a chemical point of view, they are macromolecular hydrophilic substances. Some
These include xanthan gum, sodium alginate, carrageenan, carboxymethyl cellulose, and guar gum.

Hydrocolloids have a profound impact on food Guar Gum is a good example of a Hydrocolloid which is a white color powder processed from the seeds of a plant guar. It has several good properties like its excellent solubility in water at any temperature, excellent viscosity, good stabilizer, gelling agent and emulsifier. Food Hydrocolloids publishes original and innovative research concerned with the characterisation, functional properties and applications of hydrocolloid materials. Hydrocolloids are defined as polysaccharides and proteins of commercial importance that are added Read more. foods like yogurt, ice cream and chocolate milk smooth and creamy. Beyond its role of improving texture and mouthfeel, carrageenan is a gelling, thickening and binding agent.
At present, carrageenan is the most commonly used hydrocolloid in meat foods. It has excellent water 2. Agar-Agar. Agar is a hydrophilic colloid, which is insoluble in cold water and easily soluble in hot water. Agar has 3. Konjac Gum.

For example, agar, a reversible hydrocolloid of seaweed extract, can exist in a gel and solid state, and alternate between states with the addition or elimination of heat.
The most commonly used hydrocolloids in the food production industry include; cassia gum,sesbania gum, tamarind gum, guar gum, fenugreek gum, gelatin, Arabic gum et cetera. Hydrocolloids are organic and naturally occurring, some are extracted from tree sap, seaweed, seeds or roots among other sources.

Hydrocolloids are employed in food mainly to influence texture or viscosity (e.g., a sauce). Hydrocolloid-based medical dressings are used for skin and wound treatment. Other main hydrocolloids are xanthan gum, gum arabic, guar gum, locust bean gum, cellulose derivatives as carboxymethyl cellulose, alginate and starch. For decades, food manufacturers have added hydrocolloids such as xanthan gum, pectin, and carrageenan to give salad dressings, jams, ice creams, and other foods their characteristic textures. Hydrocolloids are substances that alter the flow properties, or rheology, of aqueous solutions in which they are dispersed. Examples of a number of different food products are given and the role of the hydrocolloids in controlling their texture and properties is discussed.
