AgarGel is engaged in the manufacture of agar-agar and carrageenan, hydrocolloids extracted from red seaweeds used as gelling, thickening and stabilizing agent in several industrial applications. Our company has been a pioneer in the manufacture of seaweed derivatives in Brazil. It has been continuously improving its productive processes to deliver higher quality seaweed hydrocolloids to cater to the most demanding technical specifications devolving from any industrial segment.

Our hydrocolloids are used in a wide range of foodstuffs as a textural and functional ingredient. In regards to the biotechnology segment, our agar-agar is used to grow plants. In the pharmaceutical industry it is used as a bed for microbiological cultures as well as for the manufacture of vegan capsules. Our processed seaweeds are supplied as a source of raw material to manufacture seaweed hydrocolloids or as source of food for human consumption.


História AgargelThe Company was founded in 1973 by four immigrants, three from Japan and one from Taiwan. It was named Alganor. It began its activities as an exporter of seaweeds to Japanese hydrocolloid industries. Envisaging a possibility to industrialize the raw materials it was exporting, it invested in the acquisition of process technology to manufacture the agar-agar industrial gum.

Specialized engineers were hired in Japan, and in 1978 it started to industrialize seaweed on a small scale. The company faced all kinds of starting-out difficulties that any small outfit with scarce financial resources faces. Furthermore, there was compounded the inadequate technology to Brazilian conditions. However, still motivated by a vision and an ideal of entrepreneurial success, it kept its operations up along all these years. It developed and improved its own process technology, which allowed it to expand little by little its sales for the domestic market. In 1993, aiming to diversify its line of products, it started the manufacture of carrageenan, also a seaweed derived industrial gum. Few years later, it also started producing seaweed extract for cosmetics as well as seaweed for human consumption.

In order to improve production processes in its industrial plant, the company constantly implements modernization programs, acquires new and modern equipments and implements personnel training programs for improved operational skills. Thereby, superior product quality is obtained, gains in productivity, an increase in its productive capacity and greater competitiveness for its products vis-à-vis the international market.

In 2003, the company celebrated 30 years of activities supplying seaweed derivatives. Its visual identity was redesigned and the brand AGARGEL was created to represent the company within the new expansionist reality and its increasing insertion into the global market. The company legal and official name was changed to Agargel Industria e Comercio Ltda. in 2009.

Through years of experience, Agargel has developed an expertise in the manufacture of seaweed hydrocolloids Agar-Agar and Carrageenan as well as on their applications on food and non-food products. The company intends to continue innovating and growing in the seaweed industry.

In 2018, a brand named GELIALGAS was created to represent a company line of consumer products based on Agar-Agar.
