How Agar Stands Out in a Sea of Gelling Agents?

Hydrocolloids

Hydrocolloids are a group of polymeric substances, mainly polysaccharides and some proteins, that have the ability to form gels when in contact with water. They are essential in the food industry and in many other applications: they give texture, stability, and body to products. Among them, agar occupies a special place due to its versatility and performance.  

Extracted from red algae such as Gelidium and Gracilaria, agar forms firm, transparent, and stable gels even at low concentrations, maintaining its structure at temperatures where other gels weaken. 

Its high gelling power and thermal resistance make it ideal for the development of numerous food products.  

But agar is not alone. Each hydrocolloid has its own role. The right choice depends on the desired texture, required stability, processing conditions, and consumer dietary preferences.  

At Hispanagar, we offer a wide range of agar products and work with our customers to optimize the formulation of their products based on our in-depth knowledge of their properties.  

Comparing agar with other hydrocolloids such as gelatin, pectin, carrageenan, or xanthan gum, we see that agar combines interesting properties in a single ingredient

  • It can offer us different textures, from firm and transparent gels to creamy and spreadable textures, without the need for other additives or special pH conditions.  

  • It withstands high temperatures, maintaining its texture without melting easily.  

  • It provides a neutral base that does not alter the flavor or color of formulations.  

  • It is plant-based, ideal for vegetarian and vegan diets or in the development of plant-based products.  

For these reasons, agar has established itself as a key tool in food innovation, combining technical performance with naturalness. 

At Hispanagar, we specialize in the production and application of agar, helping our customers optimize their formulations and develop products with the desired textures.
