Setting the standard

In 1997 Seagreens® wild wrack species were the first seaweeds to be wild harvested according to DEFRA and Soil Association Organic Standards.

These remain concerned with water quality, contamination and sustainability, but alone do not assure consumers of consistent nutritional quality or composition.

Large volumes of old seaweed can be cut and sold into the human food chain, or it may be storm-cast, collected on the shoreline, and rapidly dried at high temperatures.

Small scale artisan harvesting also offers no guarantees concerning cleanliness, consistency, or nutritional composition.

Most seaweed in Europe and North America is produced on an industrial scale for alginate extraction, horticulure, and more sadly, animal feed.

Seagreens moved onward and upward from these conventional practices, developing its own methods and standards over the years. 

All Seagreens ingredients for food and nutrition product manufacturing have a fully analysed composition, batch certification and full tracability, assuring the consumer that the products are also free from allergens, contaminants, microbial pathogens and heavy metals.

Seagreens developed the careful selection, monitoring, harvesting, transportation, processing, production, packaging, and international food and medical compliance to its proprietary standard.

Since 2012 Seagreens has worked with the Seaweed Health Foundation and the Biodynamic Association to introduce an international standard for seaweed for human consumption.  

In the process, Seagreens has redefined the standards for producing human food seaweed in Europe which are now among the most advanced in the world.

In September 2016 Seagreens was Certified under the new non-governmental Nutritious Food Seaweed Quality Assurance Scheme and Standard - the world's first standard developed specifically for seaweed.

Mor information is available at the Seaweed Health Foundation's website.

Seagreens continues to develop its own unique standard and is the seaweed ingredient of choice for leading food and nutrition supplement brands.
