  • Antioxidant activity assessment in fruit liquors and spirits: methods comparison
    Publication . Santos, Carolina; Botelho, Goreti; Caldeira, Ilda; Correia, João; Ferreira, Fernanda M.
    During the last few years, Portugal has seen an increasing trend in the development of new fruit-based products, such as liquors and spirits. The antioxidant capacity of fruit liquors and spirits, sourced commercially or produced on a pilot-scale, was assessed using two simple spectrophotometric methods: the 2,2’-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays. The major goal of this work was to find which of the two methods is the most suitable and accurate in determining antioxidant capacity for fruit liquors and spirits. In addition, the total phenolic compounds of both kinds of alcoholic beverages were determined by Folin-Ciocalteau method. Despite the widespread use of DPPH assay for distilled drinks, a weak Spearman correlation coefficient (r = 0.023) between ABTS and DPPH methods in spirits were found, as well as, between DPPH values and total phenolic compounds content (r = 0.239). This work highlights the limitations of DPPH assay when used for analysis of samples with very low antioxidant capacity, as distilled spirits.
  • OLIVOTURISMO EM PORTUGAL UMA VISÃO GERAL DA OFERTA EXISTENTE PELAS PRINCIPAIS REGIÕES PRODUTORAS
    Publication . Pato, Maria Lúcia
    ntrodução: O olivoturismo, um produto turístico desenvolvido em áreas rurais, pode constituir‐se como uma nova alavanca de desenvolvimento de áreas oleícolas, induzindo o desenvolvimento da agricultura, gastronomia e cultura local. Objetivo: Ciente desta importância, o objetivo deste trabalho é observar a oferta atual e o grau de desenvolvimento do produto turístico em Portugal, um dos principais produtores de azeite a nível mundial. Métodos: Numa primeira fase, observaram‐se as regiões de produtos de azeite certificado com Denominação de Origem Protegida (DOP) no país, seguindo‐se uma pesquisa de dados (recursos) nos sites de todos os municípios das regiões DOP referidas. Numa terceira fase, esta informação foi complementada com uma pesquisa no motor de busca Google sobre o olivoturismo nos referidos concelhos. Resultados: As experiências em unidades de alojamento e as feiras e eventos relacionados com a temática, são os recursos turísticos mais utilizados para a promoção do produto turístico. Os resultados evidenciam igualmente que as seis regiões com azeite DOP estão num processo de desenvolvimento distinto da atividade turística. A Região da Beira Interior, no Centro de Portugal, é a região de Portugal onde o olivoturismo apresenta mais oferta turística, existindo aqui duas rotas de azeite que percorrem quase toda a região. Conclusão: Em Portugal o olivoturismo está num estado de desenvolvimento recente. Como um produto turístico rural que pode promover o desenvolvimento rural, carece de uma maior atenção, articulação e divulgação por parte de entidades privadas e públicas, a nível local e nacional.

  • Development of a Mediterranean Diet Recipe Index (MedRI)
    Publication . Florença, Sofia de Guiné e; Filipa P. Costa; de Pinho Ferreira Guiné, Raquel; Cunha Silva Reis Lima, Maria Joao; Teixeira-Lemos, Edite; Costa, Cristina Amaro da
    Background/Objectives: The Mediterranean Diet (MD) is globally recognized for its nutritional, environmental, and cultural value. Although several indices assess adherence to the MD and its food environments, none evaluate the alignment of individual recipes with MD principles. This study aimed to develop and validate the Mediterranean Diet Recipe Index (MedRI), a novel scoring tool designed to quantify the concordance of recipes with MD guidelines. Methods: The MedRI was conceptualized through a comprehensive literature review and expert panel assessment, integrating two main dimensions: consumption context and recipe composition. The index evaluates ingredient selection, preparation methods, and food group inclusion, with criteria adapted to specific recipe categories. Validation was conducted using a structured questionnaire administered to 244 adults living in Portugal. Statistical analyses included descriptive statistics, Spearman correlations, intra-class correlation coefficients (ICCs), Cohen’s kappa, Chi-square tests, Cramer’s V, and principal component analysis (PCA). Results: Validation results demonstrated strong internal consistency and construct validity, confirming the reliability and applicability of the MedRI in assessing recipe alignment with MD principles. Conclusions: The MedRI thus represents a reliable and innovative tool to assess and promote culinary practices consistent with the MD. It holds potential applications in nutrition education, public health policymaking, and gastronomic research, supporting the advancement of sustainable and health-promoting dietary models.
  • Bio-Regions as An Innovative Model of Sustainable Rural Development: An Integrative Literature Review
    Publication . Lagoa, Rui; Florença, Sofia de Guiné e; Tibério, Manuel; Gonçalves, Ramiro; Costa, Cristina Amaro da
    The Bio-Regions, whose origin dates back to Italy, constitute an innovative model of rural development anchored in endogenous dynamics, valuing territorial specificities, local social capital and participatory governance mechanisms. Its integrated approach seeks to articulate organic farming, environmental sustainability, community cohesion and proximity circuits. This study aims to contribute to the scientific and political debate around Bio-Regions, exploring their transformative potential in the context of territorial public policies. Through an integrative literature review, we sought to understand not only the conceptual and practical evolution of the Bio-Regions, but also the implications of their consolidation in different territorial contexts. The analysis focused on indexed scientific publications and non conventional specialized literature, collected through professional and academic networks. The selection of contributions was guided by thematic criteria, favoring studies that addressed institutional factors, the mobiliza tion of local actors and the role of public policies in the operationalization of this development model. The results highlight the decisive role of the institutional dimension in the consolidation of Bio-Regions, underlining the importance of integrated and participatory political strategies. At the same time, significant gaps in sci entific production are identified, particularly with regard to the systematic assessment of the economic, social and environmental impacts associated with the implementation of the Bio-Regions.
  • Recognizing diversity to enable an agroecological transition: understanding the potential of family farmers in Portugal
    Publication . Costa-Pereira, Inês; Aguiar, Ana A. R. M.; Delgado, Fernanda; Costa, Cristina Amaro da
    The agroecological transition of family farms in Portugal poses a significant challenge within the framework of the Common Agricultural Policy (CAP) and the European Green Deal. Despite their multifunctional contributions to rural territories, family farms—particularly smallholders—remain structurally disadvantaged by policy frameworks that continue to favor large-scale, high-input agricultural models. This study demonstrates that aligning family farming with agroecological principles yields tangible benefits and requires support through differentiated, typology-sensitive public policies. Using a tailored methodology, data were collected from 40 farms initially classified as conventional or agroecological. Ward’s hierarchical clustering, supported by complementary significance tests, identified three distinct farmer typologies: conventional, proto-agroecological, and agroecological. These typologies reflect meaningful differences in ecological integration, systemic thinking, and social engagement. The findings highlight the need for targeted policy frameworks that recognize farm diversity and promote multiple pathways toward agroecology. This typology-based approach provides an empirically grounded foundation for designing more inclusive and context-responsive institutional support for family farmers in Portugal

  • From Household to Public Sphere: Women Farmers, Gender Inequality, and Collective Mobilisation.
    Publication . Gomes, Diana; Bandeira, Cristina; Costa, Cristina Amaro da
    The MAIs Project – Women Farmers in Inland Territories – aimed to empower and promote the civic and associative participation of women farmers in S. Pedro do Sul and Sabugal, contributing to the advancement of gender equality in these regions. Using a participatory approach grounded in the principles of community development, activities were structured along three axes of intervention: personal/social, technical, and collective. This article analyses gender inequality in civic participation and highlights popular education as a key tool for strengthening collective action. When considering community mobilisation in rural contexts, it is essential to recognise the role of trust-based networks and the coordination between public policies and local actors. Women farmers face structural barriers that limit their engagement in the public sphere, including the burden of domestic and agricultural labour and persistent patriarchal norms. Thus, the centrality of labour and the gendered division of responsibilities emerged as key factors in understanding patterns of political participation and the development of collective action.

    Publication . Simões, Joana; Peleja, Ana; Neves, Cláudia; de Vasconcelos Teixeira Aguiar da Costa, Daniela; de Paiva Martins Esteves Correia, Helena Maria; Pinto, António; Ferreira Wessel, Dulcineia; Costa, Cristina Amaro da; Delgado, Fernanda; Carneiro, João Paulo; Horta, Carmo; Bahcevandziev, Kiril; Vidal, Maria; Filipe, Olga
    Agroecological transition is a major societal challenge and it is urgent to support technical solutions to answer farmers demand towards the necessary changes. The project RESTORE - biopReparados Em SisTemas prOdução agRoEcológicos aimed to study and validate the production, conservation, and use of seven biopreparations by characterizing and testing them in lettuce nurseries. The biopreparations used include prickly pear vinegar, purslane vinegar, fermented orange juice, garlic extract, nettle infusion, horsetail decoction and a biopreparation of garlic and chilli. The in vitro microbiological characterization and chemical analysis of the biopreparations, which included phenolic composition and antioxidant capacity, allowed us to understand their properties and to propose the most appropriate conservation strategy. The tests were conducted in four different moments: during the biopreparations’ manufacturing, after six months of frozen storage, and after three and six months of fresh storage. One-Way ANOVA in SPSS 29.0 and PCA comparison tests were used to analyze the results. Fermented orange juice and vinegars were the biopreparations that showed the greatest outcomes in terms of antioxidant capacity and phenolic composition. Purslane vinegar had the highest average inhibition against germs. The concentration of phenolic compounds, the antioxidant capacity, and the antibacterial activity of the biopreparations varied with time and type of conservation. It is crucial to conduct more trials, using different species and recipes, to support farmers’ decision making and adoption of agroecological solutions.
