Abstract
Macroalgae are traditionally used in human and animal nutrition. Their protein and fiber content have been widely studied
and differ according to the species, their geographic origin and their seasonal conditions. In addition to their value for
human nutrition, seaweeds have multiple therapeutically applications (e.g., weight control, hypocholesterolemic, antioxidant
and antitumor activities, others) and, in general, contribute and promote human health. In the archipelago of the Azores,
the consumption of seaweeds is widespread and accepted as a common practice in some islands. This work is aimed at providing
information on the protein and fiber content of the locally consumed species, to promote this regional food product that can
be potentially profitable from the biotechnology and commercial perspective, and also benefit public health, particularly,
taking into account the low level of marine pollution in the Azores archipelago. Protein and fiber content of eight seaweeds
(Porphyra sp., Osmundea pinnatifida, Pterocladiella capillacea, Sphaerococcus coronopifolius, and Gelidium microdon, Rhodophyta; Cystoseira abies-marina and Fucus spiralis, Phaeophyta; Ulva compressa, Chlorophyta) were determined using the Kjeldahl method and the Weende method, respectively. The protein content ranged from
6.81 to 26.62 of dry weight for C. abies-marina and U. compressa, respectively. Fiber content was generally higher as compared with that in seaweeds from other origins and ranged from 33.82
to 63.88 for O. pinnatifida and F. spiralis, respectively.
