Microbial and pest contamination in nuts: Radio frequency disinfestation and co...
Liberal, Ângela; Fernandes, Ângela; Moreira, Jorge; Fernandes, Natércia; Gonçalves, Alexandre; Ferreira, Isabel C.F.R.; Barros, LillianNuts are increasingly recognized for their rich nutritional profile and bioactive potential, making them a sig- nificant economic contributor globally. However, the commercialization of nuts necessitates stringent quality control measures to mitigate infestations by insect pests and microorganisms, which can lead to rapid deterio- ration both pre- and post-harvest. Contamination often arises from inadequate pra...
Nutritional and Biochemical Assessment of Edible Fruits From Angola's Native Flora
Rangel, Josefa; Liberal, Ângela; Pires, Tânia C.S.P.; Finimundy, Tiane C.; Barros, Lillian; Monteiro, Filipa; Romeiras, Maria M.; Fernandes, ÂngelaAngola's native flora hides a wealth of underexplored edible fruits with significant nutritional and bioactive potential. This study provides a comprehensive evaluation of the physicochemical and bioactive potential of some less explored edible fruits from this country, namely Annona muricata, A. squamosa, A. senegalensis, A. boehmii, Dacryodes edulis, and Strychnos spinosa. Nutritional profiling revealed carbo...
Chemical and Bioactive Properties of Red Rice with Potential Pharmaceutical Use
Baptista, Eugénia; Liberal, Ângela; Cardoso, Rossana V.C.; Fernandes, Ângela; Dias, Maria Inês; Pires, Tânia C.S.P.; Calhelha, Ricardo C.Red rice has been proposed as a super-food. Accordingly, the nutritional properties (AOAC), as well as its chemical composition, including sugars (HPLC-RI), organic acids (UFLC-PDA), tocopherols (HPLD-FD), and phenolic compounds (LC-DAD-ESI/MSn), together with the main bioactive properties (antioxidant, cytotoxic, antiproliferative, and antibacterial activities), were evaluated to access its nutritional benefit...
Phytochemical and bioactive potentials of African Annonaceae species
Rangel, Josefa; Liberal, Ângela; Catarino, Sílvia; Costa, José Carlos; Romeiras, Maria M.; Fernandes, ÂngelaThis review aims to gather available information on the medicinal, nutritional, and bioactive profiles of Annonaceae species in the African continent, sponsoring their use worldwide and mainly in African communities, where access to food and medicines for basic health care is scarce. >60 medicinal taxa were compiled, belonging to 22 genera, namely Annickia, Annona, Anonidium, Artabotrys, Cleistochlamys, Cleisto...
Effect of different physical pre-treatments on physicochemical and techno-funct...
Liberal, Ângela; Fernandes, Ângela; Ferreira, Isabel C.F.R.; Vivar-Quintana, Ana Maria; Barros, LillianLentils have a valuable physicochemical profile, which can be affected by the presence of antinutrients that may impair the benefits arising from their consumption. Different treatments can be used to reduce these undesirable compounds, although they can also affect the general composition and behaviour of the lentils. Thus, the effect of different processing methods on the physicochemical and techno-functional...
Determination of Carbohydrate Composition in Lentils Using Near-Infrared Spectr...
López-Calabozo, Rocío; Liberal, Ângela; Fernandes, Ângela; Revilla, Isabel; Ferreira, Isabel C.F.R.; Barros, Lillian; Vivar-Quintana, Ana MariaCarbohydrates are the main components of lentils, accounting for more than 60% of their composition. Their content is influenced by genetic factors, with different contents depending on the variety. These compounds have not only been linked to interesting health benefits, but they also have a significant influence on the techno-functional properties of lentil-derived products. In this study, the use of near-inf...
Nutritional, phytochemical, and bioactive prospects of black chokeberry (Aronia...
Sagandyk, Assem T.; Liberal, Ângela; Silveira, Tayse F. F. da; Alves, Maria José; Ferreira, Isabel C.F.R.; Zhakupova, Gulmira N.; Makangali, KadyrzhanBerries are consumed worldwide, but recently, they have attracted more attention due to their valuable phytochemical profiles and diverse applications. This study comprehensively characterized the saskatoon berry (Amelanchier ovalis) and black chokeberry (Aronia melanocarpa) from Kazakhstan, documenting their nutritional, chemical, and bioactive profiles. Nutritional analysis showed proteins at 2.52±0.2 g/100 g...
Ethnomycological prospect of wild edible and medicinal mushrooms from Central a...
Bastos, Claudete António André; Liberal, Ângela; Moldão-Martins, Margarida; Catarino, Luís; Barros, LillianIn several regions of Africa, the daily diet is partly dependent on the edible products from wild animals, plants, and mushrooms, driven by their availability, wide distribution in the local environment, and the low incomes of the general population. The documentation of ethnomycological information is particularly important to validate or correct the identification of specimens and the preservation of these na...
Nutritional, chemical and antioxidant evaluation of Armuna lentil (Lens culinar...
Liberal, Ângela; Almeida, Daiana; Fernandes, Ângela; Pereira, Carla; Ferreira, Isabel C.F.R.; Vivar-Quintana, Ana Maria; Barros, LillianLentils (Lens culinaris spp.) are a type of edible pulse consumed and produced worldwide; they are known for their valuable nutritional assets. The nutritional and chemical profiles of 34 Armun tilde a lentil samples were assessed together with their antioxidant capacity. In addition, the influence of both the climatic conditions during the growing season and the soil type in which they grow (Luvisol and Cambis...
