“…In this context, virtually every one eats some processed seaweeds every day (Dhargalkar and Verlecar 2009). Edible macroalgae are rich in resistant protein and dietary fiber (Mamatha et al 2007). Protein content differs according to species being generally low in brown seaweeds (3±15% of the dry weight) as compared with green or red ones (10±47% of the dry weight; Fleurence 1999).…”

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.

“…However, attempts are being made to use seaweed powder in food products as functional ingredient. Addition of seaweed powders in fi sh and vegetable snack products improved the functional and sensory properties (Senthil et al 2005, Mamatha et al 2007). Besides improving the functional properties, addition of seaweeds in food products would also improve the nutritional quality due to the presence of many bioactive components like antioxidative substances.…”

Radical scavenging and singlet oxygen quenching activity of extracts from Indian seaweeds

et al. 2010

Free radicals and singlet oxygen are responsible for oxidative stress related diseases and many natural compounds are known to have antioxidant properties. In this study, extracts from brown and red seaweeds of Indian origin were evaluated for their ability to scavenge different radicals and quench singlet oxygen. The crude extract in methanol and its fractions in different solvents were evaluated for their activity. The methanol extract and its fractions from brown seaweed exhibited higher 2,2′-azinobis(3-ethylbenzothizoline-6-sulfonic acid) radical scavenging activity with more than 90% scavenging in butanol and ethyl acetate fractions and correlated with polyphenol content. There was a signifi cant difference (p<0.001) in hydroxyl radical scavenging activity between different fractions of the same seaweed. Among the crude extracts, extract from Gracilaria corticata showed the highest (14.0%) activity. Crude extract from brown seaweeds showed higher peroxyl radical scavenging activity compared to red seaweeds. In fractions from brown seaweed extracts, highest activity was observed in ethyl acetate fraction (>88%) followed by hexane fraction (>40 %). Ethyl acetate fraction from crude extract showed higher inhibitory activity against hemoglobin induced linoleic acid oxidation. Singlet oxygen quenching activity of the crude extract from brown seaweed was lower (<13%) compared to red seaweeds (16.4-20.5%).

São fonte de uma grande variedade de compostos benéficos para o homem, apresentando diversas aplicações em nutrição animal e humana (URBANO; GOÑI, 2002), indústria de alimentos (MAMATHA et al., 2007), fertilização do solo (BLUNDEN, 1991) e outras áreas biotecnológicas (FARIAS; NAZARETH; MOURÃO, 2001;LIMA et al., 2004). Durante as últimas décadas, a comunidade científica demonstrou interesse crescente pelo estudo dos carotenóides e das vitaminas lipossolúveis, que podem estar associados com a redução de doenças cardiovasculares e outras doenças degenerativas (WILLIS; WIANS-Jr, 2003;JOHNSON, 2004).Os carotenóides são pigmentos naturais que se destacam principalmente devido a sua ampla distribuição nos seres vivos, grande diversidade estrutural e numerosas funções fisiológicas, dentre as quais, a principal é atuar como precursores de vitamina A nos animais (BRITTON; LIAAEN-JENSEN; PFANDER, 1995).A vitamina A dietária dá origem a uma variedade de metabólitos ativos, coletivamente conhecidos como retinóides, compostos por retinóis, retinais e ácidos retinóicos, dependendo do grupo terminal polar (NOY, 2000). A maior parte do β-caroteno e de outros carotenóides provitamina A é convertida em retinol (OLSON, 1989;ARMSTRONG;HEARST, 1996;ARMSTRONG, 1997), mas eles não são considerados micronutrientes essenciais e não existe uma Ingestão Diária Recomendada (IDR) específica. Apesar disso, no cômputo da atividade vitamina A dos alimentos, referida como retinol equivalente (RE), eles são levados em consideração. De acordo com a Resolução de Diretoria Colegiada (RDC) N o 269, de 22 de setembro de 2005, da Agência Nacional de Vigilância Sanitária, do Ministério da Saúde, que trata da IDR de vitaminas, minerais e proteínas para indivíduos e diferentes grupos populacionais, a IDR de vitamina A consiste em 600 µg de RE para adultos. Cada 1 µg de β-caroteno corresponde a 0,167 µg de RE e cada 1 µg de outros carotenóides provitamina A, a 0,084 µg de RE (BRASIL, 2005). AbstractThe aim of this work was to evaluate the potential of 32 marine macro algae species, members of Chlorophyta, Rhodophyta and Phaeophyta, as sources of α-carotene, β-carotene and α-tocopherol. Both β-carotene and α-carotene were found in all species of green macroalgae analyzed. The maximum content of α-carotene was detected in algae belonging to Caulerpa genus and the minimum in Codium decorticatum. The amount of β-carotene found was minimum in Caulerpa mexicana and maximum in Ulva fasciata. Among the Rhodophyta species, eleven contain α-carotene, the maximum content was found in Botryocladia occidental...
