Compositional and Bioactive Differentiation of Opuntia spp. Fruit Varieties by ...
Espírito Santo, Liliana; Pereira, Cláudia S.G.P.; Costa, Anabela S.G.; Almeida, Agostinho; Barreira, João C.M.; Oliveira, Beatriz; Vinha, Ana F.The nutritional, mineral, and bioactive profiles of four Opuntia fruit varieties-Opuntia robusta red variety (OR-RV) and three Opuntia ficus-indica varieties (red, yellow, and green: OFI-RV, OFI-YV, and OFI-GV, respectively)-were characterized to assess their compositional diversity and potential discriminant markers. Standard analytical procedures were applied to determine proximate composition, individual sug...
Coffee Pulp from Azores: A Novel Phytochemical-Rich Food with Potential Anti-Di...
Costa, Anabela S.G.; Peixoto, Juliana A. Barreto; Machado, Susana; Santo, Liliana Espírito; Soares, Thiago F.; Andrade, Nelson; Azevedo, RuiCoffee pulp, a by-product of wet coffee processing, shows significant potential in the food and health domains, but its real applications remain underexplored. This work investigated the chemical composition and bioactive properties of coffee pulp from São Miguel Island (Azores, Portugal). The studied coffee pulp exhibited high fiber content (52% dw), mostly insoluble; notable mineral levels (10.6%), mainly K, ...
Detailed Phytochemical Composition, Cyto-/Hepatotoxicity, and Antioxidant/Anti-...
Bouzaid, Hiba; Espírito Santo, Liliana; Ferreira, Diana M.; Machado, Susana; Costa, Anabela S.G.; Dias, Maria Inês; Calhelha, Ricardo C.Coriander, caraway, and mystical cumin are famous for their aromatic properties and widely used in Moroccan cuisine. The nutritional/phytochemical composition of their seeds (used for food flavoring and preservation) were compared. Their antioxidant, anti-inflammatory, cytotoxic and hepatotoxic effects were also explored. The fat content was similar among the samples (13%), with monounsaturated fatty acids bein...
Bioactive compounds and scavenging capacity of Adansonia digitata L. (Baobab fr...
Ferreira da Vinha, Ana; Costa, Anabela S.G.; Pimentel, Filipa B.; Santo, Liliana Espírito; Silva, Carla Sousa e; Freitas, Marisa; Fernandes, EduardaBackground: Baobab fruit is valued for its nutritional and medicinal benefits. Although it is acknowledged that baobab pulp is beneficial for health, studies that link its nutraceutical properties to the ability to eliminate reactive species (ROS and RNS) are scarce. Methods: The nutritional profile and the antioxidant properties of baobab pulp extracts from Angola were evaluated. Thus, for the first time, the ...
Almond cold-pressed oil by-product as ingredient for cookies with potential hea...
Barreira, João C.M.; Nunes, M. Antónia; Silva, Beatriz Vieira da; Pimentel, Filipa B.; Costa, Anabela S.G.; Alvarez-Ortí, M.; Pardo, J.E.tNowadays, food security is a global concern and a great scientific challenge. Agro-industrial by-productscan be used as potential ingredients of innovative food products, contributing to solve this societaldemand. By-products of high specialty oils processing, for instance, have remarkable nutritional andorganoleptic properties. Accordingly, the partially delipidified almond flour (PDAF) remaining fromalmond o...
Frutos da Opuntia: o fruto do futuro
Gomes, Alan; Espírito Santo, Liliana; Costa, Anabela S.G.; Nunes, M. Antónia; Ferreira da Vinha, Ana; Oliveira, M. Beatriz P.P.Segundo a Food and Agriculture Organisation (FAO), a produção de Opuntias (catos), para além de ser bastante rentável, é uma estratégia promissora no combate à desertificação e às mudanças climáticas globais, uma vez que esta planta tem a capacidade de se adaptar a condições climáticas extremas e consegue crescer em solos severamente degradados. A procura de plantas que estejam na base de uma agricultura susten...
Qualidade nutricional do pão: adequação à população com insuficiência renal cró...
Costa, Anabela S.G.; Pinto, Isabel; Santo, Liliana Espírito; Oliveira, M. Beatriz P. P.O pão continua a ser um dos alimentos mais consumidos pelo Homem, integrando a base da dieta mediterrânica. O seu consumo é uma questão cultural na sociedade portuguesa, sendo fundamental o controlo dos seus teores de sal. Como é sabido, a ingestão de sal pode contribuir para o desenvolvimento de doenças, tais como a hipertensão arterial (HTA) e doenças cardiovasculares. Com o objetivo de reduzir o sal ingerido...
Nutritional, chemical and antioxidant/pro-oxidant profiles of silverskin, a cof...
Costa, Anabela S.G.; Alves, Rita C.; Ferreira da Vinha, Ana; Costa, Elísio; Nunes, M. Antónia; Almeida, Agostinho A.; Santos-Silva, AliceCoffee silverskin (a coffee roasting by-product) contains high amounts of dietary fibre (49% insoluble and 7% soluble) and protein (19%). Potassium (∼5 g/100 g), magnesium (2 g/100 g) and calcium (0.6 g/100 g) are the major macrominerals. The vitamin E profile of silverskin comprises α-tocopherol, β-tocopherol, ɣ-tocopherol, δ-tocopherol, β-tocotrienol, ɣ-tocotrienol, and δ-tocotrienol. The fatty acid profile i...
The phytochemical and bioactivity profiles of wild Calluna vulgaris L. flowers
Rodrigues, Francisca; Moreira, Teresa; Pinto, Diana; Pimentel, Filipa B.; Costa, Anabela S.G.; Nunes, M. Antónia; Gonçalves Albuquerque, TâniaThe nutritional composition of Calluna vulgaris flowers as well as the phytochemical profile, antioxidant (DPPH and FRAP assays), antimicrobial and cytotoxic (in human immortalized non-tumorigenic keratinocyte and fibroblasts) activities of aqueous, hydroalcoholic and ethanolic extracts were evaluated. A high content of fiber and carbohydrates (75%) and the prevalence of α-tocopherol as vitamer deserves attenti...
Improving bioactive compounds extractability of Amorphophallus paeoniifolius (D...
Costa, Anabela S.G.; Barreira, João C.M.; Ruas, Adilson; Vinha, Ana F.; Pimentel, Filipa B.; Alves, Rita C.; Ferreira, Isabel C.F.R.; Oliveira, BeatrizElephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson) is an underground, unbranched deciduous plant that produces a large tubercle (rhizome) with recognized health effects. In this study, the influence of solvent nature (water, water/etanol (1:1) and absolute ethanol) and processing type (fresh, lyophilized and boiled) on the antioxidant activity and bioactive compounds extractability of elephant ...
