Based at the Innovation Hub (I-HUB) of Imperial College London, Tigmak Natural Polymers sources squid pens, the highest quality β-chitin source, for preparation of the biopolymer Chitosan used in pharmaceutical and medical applications.

Our technical panel is working under the direction of world leading academics from Imperial College in the fields of biomaterials and polymer synthesis. Tigmak is focused in the preparation of pharmaceutical grade Chitosan from a marine source. 

β-chitin is obtained from squid pens, which are usually discarded in the processing of squid for human consumption. Following cleaning and processing in Europe, squid pens are further processed in the U.K. in a strictly controlled environment.

TIGMAK Squid Pens

β-chitin is a polysaccharide obtained from sustainably sourced squid pens. Watch the video below to see how Tigmak squid pens are harvested and cleaned in Europe, before shipping for preparation in a strictly controlled laboratory environment.

What is Chitosan

Chitosan is a natural polymer made from chitin, a polysaccharide not dissimilar to cellulose, which is commonly obtained from shrimp, crab, and squid.

Once processed, chitin yields Chitosan, a non-toxic, biodegradable, and biocompatible polymer, making it a scientifically and commercially significant product, with a number of highly specialist pharmaceutical applications.

Chitosan Applications and Scientific Developments

Applications of Chitosan vary, from fertilisers to stem cell scaffolds, and depend on the quality and purity of the Chitosan polymer.

Chitosan has been a focus of research and industry for some years, with pharmaceutical grade Chitosan increasingly being used in the synthesis of next generation medicines.

Tigmak prepares pharmaceutical grade Chitosan, for research and development in wound healing treatments, implant coating, gene and stem cell delivery systems, drug delivery systems, tissue engineering, 3D cell culture scaffolds, biodegradable scaffolds, and electrospun nanomaterials.

TIGMAK Sourcing of β-Chitin

Tigmak β-chitin is sustainably sourced from accredited wild squid fisheries in the Atlantic Ocean off the coasts of Africa and Latin America. Tigmak’s chosen fishing waters have the lowest toxicity levels in the world, meaning that produce from this region has much lower bio-accumulations of contaminants such as lead, mercury or cadmium.

Fishing Locations

Our squid are fished sustainably for the food industry.
Squid pens are harvested during processing and would otherwise be discarded.
