RESUMO
A Corema album L. D. Don, (camarinha) é uma planta marítima endémica da Península Ibérica que pode ser encontrada em zonas dunares ao longo da costa atlântica. O estudo apresentado é uma contribuição para a valorização da C. album através da utilização de técnicas de propagação da planta, da caracterização físico-química e de ensaios de conservação.
No estabelecimento ex vitro por estacaria, sem hormona, em substrato perlite, obteve-se 25 % de enraizamento e uma taxa de germinação em substrato orgânico de 25 %. A taxa de germinação obtida in vitro foi de 10 %. Relativamente à caracterização físico-química das bagas foi registado um pH de cerca de 3 e um teor de sólidos solúveis (ºBrix) próximo de 8. Através da utilização de técnicas espectroscópicas ATR-FTIR e FT-Raman, comprovou-se a análise nutricional relativamente ao elevado teor de humidade, fibras, hidratos de carbono e compostos fenólicos. Após a colheita, as bagas mantiveram-se próprias para o consumo nos períodos de conservação de duas e de quatro semanas à temperatura ambiente e a 4ºC, respetivamente.

ABSTRACT The Corema album L. D. (camarinha) Don is a marine plant endemic to the Iberian Peninsula that can be found in dune areas along the Atlantic coast. The study presented is a contribution to the valuation of C. album through the use of plant propagation techniques, physicochemical characterization and conservation trials. In the ex vitro establishment by staking, without hormone, in perlite substrate, 25% of rooting was obtained and a germination rate in organic substrate of 25%. The germination rate obtained in vitro was 10%. As regards the physicochemical characterization of the berries, a pH of about 3 and a soluble solids content (ºBrix) of about 8 were registered. Using the ATR-FTIR and FT-Raman spectroscopic techniques, the nutritional analysis high moisture content, fibers, carbohydrates and phenolic compounds. After harvesting, the berries were kept for consumption in storage periods of two and four weeks at room temperature and at 4 ° C, respectively.
