Extraction technology


World-class advanced manufacturing

Marinova is an ISO9001 and HACCP certified company, producing high purity fucoidan extracts under GMP. Our corporate headquarters in Tasmania, Australia, comprise an API-standard manufacturing plant and state-of-the-art research laboratories. Designed and built to accommodate our proprietary technologies and processes, this world-class facility provides Marinova with the unique ability to produce fucoidan extracts of unrivalled quality and efficacy.

Exclusive extraction technologies

Manufacturers of fucoidan have traditionally utilised solvents to precipitate the fucoidan polymer from crude seaweed extracts. This traditional methodology may lead to contaminants being present in the final extract. Fucoidans manufactured in this way can suffer from many shortfalls; their quality can be inconsistent, their chemical integrity may be compromised and – most importantly – their bioactivity may be affected.

Marinova's exclusive extraction technology overcomes these problems. The process does not use organic solvents and produces fucoidan extracts that remain unadulterated in chemical structure and free from solvent residues. The mild, aqueous process also ensures the resulting extracts comply with the most rigorous quality standards and regulatory requirements.

Marinova's unique extraction process produces efficacious, high purity fucoidan extracts that are certified organic. The advanced process technologies can also be used to create high purity extracts with specific sulfation profiles and defined molecular weights. It is this unique ability to modify the key structural elements that enables Marinova to produce fucoidans with enhanced bioavailability and distinct bioactivities for pharmaceutical research.

Marinova's exclusive extraction technology is summarised below:

  1. Pure seaweed source

    Pure seaweed source

    Wild, certified organic seaweed is hand-harvested from the world’s cleanest ocean waters.

    Freshly harvested seaweed is immediately air-dried to preserve maximum bioactivity.

  2. Aqueous extraction

    Aqueous extraction

    Pure water physically separates whole fucoidan compounds from the seaweed matter.

    No harsh solvents are used, which ensures the natural fucoidan structure is preserved.

  3. Proprietary filtration

    Proprietary filtration

    Two stages of specific filtration developed by Marinova capture and purify the fucoidan.

    All nutrient-rich by-products are then utilised in certified organic horticultural applications.

  4. Concentration


    Purified fucoidan is carefully dewatered to produce a highly concentrated extract.

  5. Dehydration


    Specialised technology dehydrates the fucoidan concentrate to create a shelf stable, free-flowing powder.

    This powdered fucoidan is then immediately sealed and stored.

  6. Quality testing & release

    Quality testing & release

    Highly qualified technicians perform multiple tests throughout the entire process of each batch to ensure compliance with all key quality parameters prior to release. Detailed specifications are provided with each product order.
