  • Chemical composition and omega 3 human health benefits of two sea cucumber species of North Atlantic
    Publication . Sales, Sabrina; Lourenço, Maria Helena; Pessoa, Maria Fernanda; Pombo, Ana; Félix, Pedro Miguel; Bandarra, Narcisa Maria
    The main goal of this study was to investigate the seasonal chemical changes of two sea cucumber species caught from Portugal. The potential contribution to human health of lipids was also evaluated. For this, the chemical composition (protein, ash, and fat) and lipids composition of Holothuria arguinensis and Holothuria forskali was followed in summer and winter. Both species presented adequate levels of protein and ash and low content of total lipids, although their lipid profile showed a high proportion of polyunsaturated fatty acid (PUFA). Eicosapentaenoic acid (EPA) was abundant in all samples, and a favorable and similar n-3/n-6 ratio was found for both species. The atherogenic and thrombogenicity indices and ypocholesterolaemic/hypercholesterolaemic ratio suggests a high-quality for H. arguinensis and H. forskali. In general, significant differences were observed between species but not between summer and winter. Some significant variations were observed between summer and winter in the lipid profile of both species and in the chemical composition of H. forskali. Results indicate that these species have adequate nutritional quality for human consumption and may be suitable for the development of reliable fatty acid guides in sea cucumbers.

  • Corema album spp: Edible wild crowberries with a high content in minerals and organic acids
    Publication . Brito, Catarina; Bertotti, Taciana; Primitivo, Maria João; Neves, Marta; Pires, Cristiana L.; Cruz, Pedro F.; Martins, Patrícia A. T.; Rodrigues, Ana Cristina; Moreno, Maria João; Brito, Rui M. M.; Campos, Maria; Vaz, Daniela C.; Pessoa, Maria Fernanda; Lidon, Fernando; Reboredo, Fernando; Ribeiro, Vânia S.
    Edible wild plants are part of the ethnobotanical and gastronomic heritage of different geographical areas. Corema album (L.) D. Don is an endemic species of the dune systems of the Atlantic coast of the Iberian Peninsula. The aerial parts of Corema album are a source of nutrients and antioxidants. The Corema album white berry (Portuguese crowberry) is rich in calcium, iron, and zinc. The plant also shows high phenolic content and antioxidant capacity associated with the leaves, fruit, and flowers. The presence of organic acids, namely phenolic acids, such as hydroxycinnamic acids, and long chain polyunsaturated fatty acids (PUFAs) omega-3 and omega-6 has also been confirmed. Toxicity studies evaluated by cell viability tests with human intestinal epithelium model cells (Caco-2) have shown that, at low concentrations, plant extracts may present beneficial effects.
