The Heart Of Seaweed Innovation


Red Seaweed From Scandinavian Cold Waters

Red seaweed Furcellaria lumbricalis , historically also known as Furcellaria Fastigiata. The drifting and attached forms of Furcellaria lumbricalis and Coccotylus truncatus form a loose-lying algal stratum in Kassari bay, Estonia, which is the most abundant community in the Baltic Sea. Furcellaria lumbricalis is a source of unique texturant –  furcellaran. Among people, furcellaran is known as vegan gelatine.

Furcellaran can be used in many fields, offering alternative for other gums and texturing agents, also oil-based and non-sustainable ingredients. 

We’ve gathered some articles for you to explore, these articles are written by independent scientists across the world and are not related to Est-Agar AS. However, articles should guide you through different opportunities in various industries. Collection of articles in this page is just a small amount of research that is carried out about furcellaran. If you are interested about certain topic or industry, that is not listed here, feel free to reach out to us. We always do our best to provide you necessary information.


Secret Treasure in The Baltic Sea

According to our current knowledge Kassari bay red seaweed resources are the only ones left in the world industrially usable and we are licensed owners of the quota.

Although Furcellaria lumbricalis is found in Estonia, Denmark, Poland, Latvia and Canada, today only the Estonian company Est-Agar produces furcellaran. In other locations, algal stocks have declined or disappeared entirely as a result of trawling or pollution. However, it is still important to mention that the first factory producing furcellaran was launched in Denmark in the 1940s. Hence, another common name for the seaweed is Danish agar.

Kassari Bay has 54 monitoring stations that measure Furcellaria lumbricalis quantity and evaluate the biodiversity. Based on the information received from the stations, every other year, a new quota is calculated by the Estonian Marine Institute. It’s not only the quantity thats being calculated, evaluation of catching places are being set as well – taking into account proportion of seaweed mass, coverage and all other species – plants and animals – that could be affected. Sustainable approach and not harming natural reproduction rate is always kept in mind, within protecting all species in the area. Kassari Bay red seaweed’s whole mass is approximately 200 000t, quota set is 2000t (≈1%).

Seaweed caught and collected from Väinameri on average contains a maximum of 8% of additives. Gathered material is dried and stored having a maximum of 22% moisture content. 

In addition to catching, local people gather seaweed storm casts from shore, dry it in the sun and sell it to us. Maintaining this tradition brings families and people together, and helps to keep the Baltic Sea shores clean.

Also, Est-Agar AS is an important employer in Saaremaa, Kärla region. Providing different career opportunities to approximately 25 people and the number is growing.

The safety of furcellaran and its production is guaranteed by the systematic analysis of hazards and critical points. The production’s compliance to HACCP requirements is under control of Veterinary and Food Board. Strict and careful quality control checks are made in every stage of production from accepting the seaweed to sale. All lots are tested and guaranteed to comply with the specifications and standards.

Furcellaran is classified together with carrageenan (E407) and complies with EU directive 2009/10/EC, Food Chemical Codex and JECFA standards. Although it is very important to note here that even though furcellaran is classified together with carrageenan, it is still a standalone polysaccharide with similar good properties – rigid or elastic, clear or turbid, tough or tender, heat stable or thermally reversible, low or high melting/gelling temperatures, but lacks the negative properties. Furcellaran is fully safe and contains no danger for health.

Furcellaran is anionic partly sulphated polysaccharide which is classified together with carrageenan (E407).

The structure of furcellaran is similar to that of kappa carrageenan and has been described as a hybrid of kappa/beta carrageenans complex. The essential difference is that kappa carrageenan has one sulphate ester residue per two sugars, while furcellaran has one sulphate ester residue per three or four sugar residues.

Furcellaran is polysaccharide consisting of repeated disaccharide units of beta (R1 = R2 = H) and kappa carrageenan (R1 = SO3-, R2 = H). The structures of repeating disaccharide units of furcellaran and carrageenan are shown in figure 1.


(a) kappa carrageenan (R1= SO3–, R2= H), beta carrageenan (R1= R2=H), furcellaran (R1= SO3–, R2= H) (R1= R2= H), iota-carrageenan (R1= R2= SO3–)

(b) lambda-carrageenan (R3 = R4= SO3–)

Furcellaran is composed of D-galactose, 3,6-anhydro-D-galactose and D-galactose- 4-sulphate.

Furcellaran is extracted raw seaweed Furcellaria lumbricalis and the liquid extract is purified by filtration. The liquid extract may be converted into flaky furcellaran by evaporation of water to yield by drum drying. Proper release of the dried material from the dryer roll requires addition of a small amount of roll-stripping agents (foo doil).

Also the furcellaran can be isolated from the liquid extract by precipitation of the furcellaran with potassium chloride. This process gives a pure and concentrated product.

Our Mission

We are dedicated to a sustainable future through expanding the range of use of furcellaran from purely natural origin without threatening its natural reproduction rate.

Our Footprint

Currently 20kW Solar Power source installed, plan to expand to be fully self-sufficient green energy using manufacturer

Initial cleaning and washing of seaweed only with rain water

Waste water is release back to the nature clean and safe

In the last resource audit, we analyzed the usage of electricity, machinery effectiveness, material usage in order to lower consumption in all areas. All electrical motors and systems were renewed with low energy consumption machinery.

Excess heat from production is reversed back to the facilities own heating system

100% natural planting pots will replace plastic pots that are currently used in herb and plant growing companies

Through it, we are helping to reduce the effect of eutrophication. Which is one of the main threats to the biodiversity of the Baltic Sea and is caused by excessive inputs of nutrients to the marine environment
