Nori has a high protein content of up to 48% dry matter. Also very rich in
polysaccharides, it contains provitamin A, vitamin B12, potassium, magnesium,
calcium and eicosapentaenoic acid, a fatty acid known to thin the blood. This action is
further increased by the presence of taurine, a relatively rare free amino acid. This
gives a great potential to this alga, whose regular consumption has preventive
effects against certain cancers.
Nori's flavor is musky, reminiscent of smoked green tea. For some, the taste is more
earthy than marine, which accounts for its great reputation! Nori’s renown is also due
to its very high protein content - 10g of Nori = a rib of beef!
Its very soft leaves are used raw (marinated) or cooked for the making of sushi, maki
and other usages giving free rein to inventiveness.
