Exploring the Biochemical Profile of Beta vulgaris L.: A Comparative Study of B...
Almeida, Daiana; Petropoulos, Spyridon A.; Silveira, Tayse F. F. da; Pires, Tânia C.S.P.; Ferreira, Isabel C.F.R.; Fernandes, Ângela; Barros, LillianIn this study, leaves and roots from three beetroot cultivars (cv. Albina Vereduna (white roots), cv. Burpee’s Golden (golden roots), and cv. Pablo F1 (red roots)), as well as Swiss chard leaves (also known as “rhubarb chard”, or Beta vulgaris subsp. cicla var. flavescens) were evaluated in terms of their chemical profile and bioactive properties. Roots were characterized by high carbohydrate content, which als...
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...
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...
Exploring the potential of underrated yet versatile crop Lunaria annua L.: New ...
Petrović, Jovana; Almeida, Daiana; Fernandes, Ângela; Stojković, Dejan; Robajac, Dragana; Silveira, Tayse F. F. da; 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 ...

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...
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...
How Does Domestic Cooking Affect the Biochemical Properties of Wild Edible Gree...
Liava, Vasiliki; Fernandes, Ângela; Reis, Filipa S.; Finimundy, Tiane C.; Mandim, Filipa; Pinela, José; Stojković, Dejan; Ferreira, Isabel C.F.R.Wild edible greens are a key ingredient of the so-called Mediterranean diet and they are commonly used in various local dishes in their raw or processed form. Domestic processing of edible greens may affect their nutritional value and chemical profile. In this work, six wild species (e.g., Cichorium spinosum L. (S1); Centaurea raphanina subsp. mixta (DC.) Runemark (S2); Picris echioides (L.) Holub (S3); Urosper...
