Health & nutrition(humans and animals)

– Gut health (fibers, prebiotics)– Immune stimulation– Anti-oxidants– Anti-inflammatory– Anti-biotic– Protein– Vitamins– Minerals– Fatty acids– Skin health (cosmetics)– Animal fur and mucus health– Pharmaceuticals/bioactives

Human food– Sea vegetables, snacks– Salt replacement– Flavor– Texturizer

Industrial fermentation– Biofuels– Biochemicals– Single cell protein (SCP)– Biorafinery

Specialty chemicals– Alginate, carrageenan, agar– Alginate derivatives– Fucoidan– Mannitol and derivates– Fiber/textiles– Minerals

Global markets

Global production of seaweedGlobal seaweed production

• Yearly production of 30 million tons seaweed (FAO, 2016)

• Mainly aquaculture in Asia (95%)

• Production in Europe mainly in France, Ireland, UK, Spain, Iceland, The Faroe Islands and Norway

• European consumers bought 5000 tons of seaweed for culinary uses in 2014 (Organic Monitor, 2014).

• Asian products currently dominate the European market of seaweed food products

• Increasing awareness of environmental issues as well as food safety causes an increasing demand of European seaweeds which are local, organic and traceable

• Seaweed is healthy – The new ”superfood”

– Excellent source of fiber, minerals and trace elements, incl. iodine

– Contains valuable protein, omega-3 fatty acids, vitamins and

antioxidants

– Low in sodium (salt replacement) and low in calories

• Seaweed is tasty – The new food trend

– Salty, ”umami”, ocean flavor – highly valued in Asian cuisine and

new trend among chefs in Europe

– Bright green color (after blanching/boiling)

– Can be used to add flavor, color and texture in food products

• Seaweed is sustainable – The food of the future”

– No need for feed, fertilizer, freshwater or land area

– Seaweeds are sea vegetables

– Vegetarian friendly

– Organic and traceable production

Why use seaweed in food products?

• Risks by consumption of seaweed assessed by NIFES in 2016 (requested by Norwegian Food Safety Authorities)

• The most important risk factors in seaweed appear to be iodine, cadmium and inorganic arsenic, but there is a need for more knowledge regarding variation in composition, effects of processing, bioavailability and consumption patterns.

• No current regulation of upper limits of metals in seaweed for human consumption (except for seaweed as ”additives”)

• EFSA has identified seaweed as an “emerging risk” and are working on a “commision recommendation” on the monitoring of metals in macroalgae and halophytes.

• Planned and on-going research in SES:

– Investigate how various processing methods affects the content of risk components in seaweed

• Estimated daily consumption of Saccharina latissima in order to obtain the recommended daily intake (RDI, 150 µg/day*) and the tolerable upper limit (UL, 600 µg/day*) of iodine

• The iodine content was found by alkaline extraction of iodine from Saccharinalatissima harvested at SES’ farm, May 2016

• Little information about the bioavailability

*Defined by the World Health Organization (WHO)

The high iodine content (especially in S. latissima)can also be an advantage, as the general iodine status of the European population is low.

Variation of Iodine Content in Processed Cultivated S. latissima

- Important to develop food products that are tasty, healthy and safe

- SES is taken an active role in product development, together with students and food producing companies

Product development

• Air dried (35C) and pulverized seaweed

• 0.00% - 0.56% - 1.00% - 1.44%

• Sensory analysis (elderly people 70-80 years old)

• Most of the judges (60 in total) preferred the fish burgers containing the highest amount of seaweed

0.00% 0.56% 1.00% 1.44%

Product development: Fish burgers with A. esculenta
