Exploring the potential of underrated yet versatile crop Lunaria annua L.: New ...
Petrović, Jovana; Almeida, Daiana; Fernandes, Ângela; Stojković, Dejan; Robajac, Dragana; Silveira, Tayse Ferreira; Barros, LillianLunaria annua is an underexplored crop with promising potential for use in various industries: food, oil etc. It grows rapidly, has low maintenance and high resistance to pathogens, which makes it a promising crop for sustainable cultivation. Herein, we investigated nutritional value, phenolic profile, and bioactive properties of L. annua seeds collected in the wild. The results we obtained indicate that seeds ...
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...
Biotechnological approaches for reducing antinutrients and enhancing lentil (Le...
Liberal, Ângela; Fernandes, Ângela; Pires, Tânia C.S.P.; Ferreira, Isabel C.F.R.; Vívar-Quintana, Ana Maria; Barros, LillianThis study explores the effects of germination and cooking as pretreatments, followed by fermentation using different starter cultures on the physicochemical, nutritional, and techno-functional properties of Beluga and Du Puy lentil flours, focusing on reducing antinutritional factors and enhancing nutrient bioavailability. Fermentation was conducted using lactic acid bacteria (Furfurilactobacillus rossiae and ...
Innovative fortified kale soup formulation designed for the elderly
Duarte, Cristina; Pinheiro, Rita; Mata, Fernando; Pinto, Elisabete; Fernandes, Ângela; Vaz-Velho, ManuelaThe nutritional needs of the elderly require immediate attention. Strategies to incorporate healthy, high-fibre, protein-rich ingredients into traditional diets have been identified to enhance health benefits. This study aimed to develop a new food product specifically for older adults, using kale (Brassica oleracea L. var. acephala DC), and to evaluate its nutritional, sensory, and antioxidant properties. Acce...
Bark-based biorefineries: anatomical and chemical characterization of the bark ...
Şen, Ali Umut; Simões, Rita; Yücedağ, Cengiz; Quilhó, Teresa; Sousa, Vicelina; Miranda, Isabel M.; Fernandes, Ângela; Pereira, HelenaThe detailed anatomical and chemical features of the bark from endemic Quercus vulcanica in Turkey are reported here for the first time and discussed in the perspective of integration into a bark-based biorefinery system. The bark of Q. vulcanica trees was collected and studied through observations using light and scanning electron microscopy, wet-chemical analysis, inorganic elemental and FTIR analyses, GC-MS ...
Food from the Wild—Roles and Values of Wild Edible Plants and Fungi
Catarino, Luís; Romeiras, Maria Manuel; Fernandes, ÂngelaHumans have used a multitude of wild species of plants, fungi, and animals for food and medicinal purposes. However, with the widespread establishment of industrial agriculture and globalization, the numbers of consumed plant, animal, and fungi species have significantly reduced. While in most developed or urban societies, virtually only cultivated or bred species are consumed, rural communities in many countri...
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...
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...
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...
