    O café sombreado da serra de Baturité, Ceará, Nordeste do Brasil: gestão ambiental, sustentabilidade e impactos eco-ssocioeconômicos
    (Universidade do Vale do Itajaí, 2023-09-15) Ribeiro, Sofia Regina Paiva; Lima, Filipe Augusto Xavier; Loiola, Maria Iracema Bezerra
    O café sombreado da serra de Baturité, uma das poucas plantações no Brasil que integram lavoura-floresta, configura-se como uma antítese ao modelo agrícola predominante em nosso país, em monocultivo. Conhecido como “café de Baturité”, é apreciado por ser originário da variedade típica da espécie arábica (Coffea arabica) sombreada, com produção realizada por pequenos produtores rurais familiares, de forma agroflorestal. Diante desse cenário, o presente artigo objetiva verificar o impacto da revitalização da cultura do café de sombra na serra de Baturité a partir de iniciativas voltadas para o turismo, preservação ambiental e desenvolvimento socioeconômico regional. O procedimento metodológico adotado contempla estudo bibliográfico, observação participante e entrevistas semiestruturadas, com fontes-chave. Para tanto, as informações foram catalogadas, analisadas e confrontadas através da triangulação dos dados. Os resultados evidenciam que a cafeicultura, inserida na região há dois séculos (1822-2022), se encontra em fase de revitalização. Essa revalorização do cultivo, agora com conhecimentos empírico e técnico, vem contribuindo para minimizar o impacto antrópico na prática agrícola serrana, ampliar a gestão socioambiental nas propriedades rurais (onde o café se tornou um vetor de desenvolvimento sustentável) e fomentar a economia regional, como se observa a partir das ações voltadas para o ecoturismo, o empreendedorismo rural e a economia circular.

    Selection of genotypes of Coffea arabica for drought tolerance based on anatomical and physiological characteristics
    (Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2025-03-31) Santos, Cyntia Stephânia dos; Freitas, Ana Flávia de; Silva, Glauber Henrique Barbosa da; Tavares, Maria Clara dos Santos; Carvalho, Milene Alves de Figueiredo; Santos, Meline de Oliveira; Carvalho, Gladyston Rodrigues; Silva, Vânia Aparecida
    Climate change affects crop productivity, with forecasts for the coming years pointing to increased temperatures and changes in rainfall distribution. This paper aimed to identify genotypes of Coffea arabica that are potentially drought-tolerant. Seven germplasm genotypes of Timor Hybrid were evaluated in comparison to two cultivars considered as sensitive and drought-tolerant. These were submitted to two water treatments, the first maintaining water availability and the second with complete suspension of irrigation. The physiological characteristics analyzed were gas exchange and predawn leaf water potential. For leaf anatomy, characteristics of the leaf lamina, conductive vessels and stomata were evaluated. It was found that some genotypes were able to maintain gas exchange even under low water availability. For these genotypes, the analysis of leaf anatomy presented an increase in cuticle thickness on the adaxial face, in the relationship between polar and equatorial diameters of stomata, in addition to a lower vulnerability index. A positive relationship was observed between adaxial phase cuticle thickness and water use efficiency. The Timor Hybrid UFV 377-21, UFV 376-31 and the cultivar IPR100 were the highlights among the genotypes analyzed, which presented adaptations that allowed the maintenance of the hydric status in the initial development phase.

    Informações e inovação na rede social de produtores de café ecológico – Ceará
    (Universidade Estadual de Campinas, 2024-08-16) Braga, Francisco Laercio Pereira; Campos, Kilmer Coelho; Lima, Filipe Augusto Xavier; Ribeiro, Luiz Carlos de Santana
    Este trabalho constrói e analisa a estrutura da rede social de produção de café sombreado/ecológico da região do Maciço de Baturité, no Estado do Ceará. Para tanto, foram realizadas pesquisas de campo e estudo de caso com 36 produtores de café ecológico dos municípios de Mulungu, Baturité e Guaramiranga, aplicando-se o conceitual de Análise de Redes Sociais (ARS). Os principais resultados mostram que a densidade da rede da região ficou em 6,7%. Isso reforça o argumento de que as informações circulam em menor velocidade e de que há pouca interação dos atores da rede para troca de ideias, experiências, erros e acertos individuais e coletivos, fator limitante para o conhecimento de inovações implementadas por outros produtores locais. A atuação das universidades, associações de produtores, poder público e instituições de apoio são importantes para troca de informações sobre produção e comercialização do café ecológico e para estimular as inovações a serem exploradas.

    European strategic trade policy and Brazilian export growth during the nineteenth century
    (Departamento de Economia da Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo (FEA-USP), 2022-04-04) Absell, Christopher David
    Until the Amazonian rubber boom, cane sugar and coffee were the two most important export commodities for Brazil during the nineteenth century. Despite inherent differences in methods of cultivation, both sugar and coffee at once benefitted and suffered from the characteristics of Brazil’s factor endowment in land, labour and capital. Yet these two export commodities demonstrated divergent growth patterns across the nineteenth century. The difference was not one of relative productivity and thus price competitiveness disadvantage, but of the imperfectly competitive nature of the international market for each commodity. European governments actively practised strategic trade policy to transfer profits from foreign to domestic or colonial firms. These market distortions were exogenous, imposed by consumer markets, and took the form of European colonial tariff preferences and subsidies to domestic production. Coffee suffered less from imperfect competition, thus remaining more profitable to Brazilian agricultural producers in the long run.

    (Sociedade Brasileira da Ciência das Plantas Daninhas, 2022-09-30) Rodrigues, Rafael J. A.; Carvalho, Gladyston R.; Gonçalves, Adenilson H.; Carvalho, João Paulo F.; Alcântara, Elifas N. de; Resende, Laís S.
    Background Phytosociological surveys of weeds in agricultural regions, such as the coffee growing Cerrado Mineiro Denomination, are essential for understanding the predominant species in a cultivation area. Objective This study aimed to determine the predominant weed species in coffee crops in Cerrado Mineiro through phytosociological surveys during two periods of the year. Methods 26 coffee farms in 12 municipalities within the Cerrado Mineiro Denomination of Origin of were visited. The inventory square method was used for the phytosociological surveys. In each area, 40 m2 was evaluated and divided into two study periods (summer and winter). Calculations of the variables were performed using the following data: frequency, density, abundance, importance value index, similarity coefficient, rarefaction curve, Shannon index, and hierarchical grouping analysis using Jaccard’s similarity. Results In the summer (rainy period), 54 species from 16 families were found, with Poaceae, Asteraceae, and Amaranthaceae predominating. In winter (dry season), 56 species from 16 families were found, predominantly Asteraceae, Poaceae, and Brassicaceae. There was a predominance of 17 and 16 species, with similarity levels (Jaccard) of 45.58% and 40.78% for summer and winter, respectively. Conclusions The weed community in the Cerrado Mineiro coffee plantation is dominated by two main families, Poacaeae and Asteraceae, with Eleusine indica (summer) and Conyza spp. (winter) being the species with the highest importance values.

    Leaf extract of Coffea arabica L. reduces lipid peroxidation and has anti-platelet effect in a rat dyslipidemia model
    (Faculdade de Ciências Farmacêuticas da Universidade de São Paulo, 2022-09-02) Simões, Mario Henrique Souza; Salles, Bruno Cesar Correa; Duarte, Stella Maris da Silveira; Silva, Marcelo Aparecido da; Viana, André Luiz Machado; Moraes, Gabriel de Oliveira Isaac de; Figueiredo, Sonia Aparecida; Ferreira, Eric Batista; Rodrigues, Maria Rita; Paula, Fernanda Borges de Araújo
    This study aimed to evaluate the antioxidant potential of the Coffea arabica Lineu (L.) leaf extract and its effects on platelet aggregation of dyslipidemic rats. The extract was obtained by the percolation of C. arabica L. leaves in hydroethanolic solution 70% (v/v). The mass spectrometry FIA-ESI-MS² suggested the presence of chlorogenic acid, rutin acid, and quinic acid. The DPPH• radicals scavenging capacity was demonstrated (IC50 = 0.06 mg/mL). The extract was administered to rats by gavage (300 mg/kg/day) for 56 days. Dyslipidemia was induced by administering Triton WR-1339 (300 mg/kg body weight) on the 54th day. On day 56, blood was collected by puncturing the abdominal aorta artery and the aortic artery was removed. Lipid profile, markers of renal and hepatic injury, lipid peroxidation, and platelet aggregation tests were carried out. The ingestion of extract reduced the lipid peroxidation (aorta and plasma) and platelet aggregation in dyslipidemic rats. The extract did not affect markers of renal and hepatic function as analyzed in this study, suggesting neither impaired liver nor kidney function in these animals. Therefore, our results demonstrate that the extract of leaves of C. arabica L. show antioxidant potential in vitro and in vivo as well as anti-platelet aggregation in dyslipidemic animals.

    Influence of Fermentation Time and Inoculation of Starter Culture on the Chemical Composition of Fermented Natural Coffee Followed by Depulping
    (Academia Brasileira de Ciências, 2024-09-09) BORÉM, FLÁVIO M.; SALVIO, LUÍS GUSTAVO A.; CORREA, JEFFERSON LUIZ G.; ALVES, ANA PAULA C.; SANTOS, CLÁUDIA M. DOS; HAEBERLIN, LUANA; CIRILLO, MARCELO A.; SCHWAN, ROSANE F.
    Fermentation using starter cultures has been considered an alternative and economically viable technology for the production of specialty coffees. This type of technology promotes several benefits, such as increased sensory quality, control over the fermentation process, predictability of the final product and added value. Coffee (Coffea arabica L.) samples for this study were collected in Presidente Olegário - MG (2018/19 crop year) in the Cerrado region of Minas Gerais. The effects of natural fermentation and inoculation of the yeast Torulaspora delbrueckii and duration of fermentation (0, 24, 48, 72 and 96 hours) on the sensory and chemical quality (analysis of bioactive, volatile, and organic compounds and fatty acids) of coffee were evaluated. The objective of this study was to determine the effect of fermentation time and starter culture inoculation on the chemical composition of fermented coffees. Fermentation time significantly influenced the sensory description of the coffee beverage, with notes of honey, brown sugar and almond predominating up to 48 hours, for coffees fermented for 72 and 96 hours the notes described were and fruity, winey notes. The chemical composition was primarily influenced by fermentation time.

    Experimental model for optimizing mechanized mountain coffee harvesting
    (Departamento de Engenharia Agrícola - UFCG, 2024-08-30) Souza, Felipe G.; Teixeira, Mauri M.; Villibor, Geice P.; Furtado Júnior, Marconi R.; Cecon, Paulo R.
    Coffee holds significant economic and social importance for Brazil, being one of the main commodities in global agribusiness. Coffee growers, particularly those cultivating arabica coffee, face challenges due to labor shortages and high associated costs during manual harvesting. This study aimed to evaluate the operational performance and efficiency of a self-propelled coffee harvester prototype in terraced mountain areas. To assess harvesting losses, efficiency, and operational capacity, the experimental model traversed the designated area entirely. Fruit stripping was performed over the collection system at five different terrain incline angles (8°, 17°, 25°, 30°, and 38°). Harvesting loss was determined by the ratio of the mass of fruits retained by the collection system to the total mass of harvested fruits. For comparison, the efficiency and operational capacity of two workers performing manual fruit harvesting were also measured. Terrain slope did not significantly impact harvesting losses or operational capacity. The highest operational capacity was 0.11 ha h⁻¹, achieved at a 17° slope. The average operational efficiency was 66.2%.

    (Universidade Federal do Ceará, 2024-05-17) Peixoto, Priscilla Moreira Curtis; Osório, Vanessa Moreira; Colodetti, Tafarel Victor; Parreira, Luciana Alves; Dalvi, Leandro Pin; Tomaz, Marcelo Antonio
    Du e to the concern with the contamination of food by pesticides, especially coffee, the aim of this study was to analyze the chemical composition and glyphosate residue in Conilon coffee beans with and without defects and harvested at different times after applying the herbicide. The experiment was in a split-plot design, with the presence or absence of defects in the beans comprising the subplots, and the periods of 15, 30, 45 and 60 days after applying the herbicide corresponding to the split plots. We analyzed the volatile compounds, bioactive compounds, and glyphosate residue in the beans. Regardless of the presence or absence of defects, there was an increase in the concentrations of bioactive compounds in the raw Conilon coffee beans as the interval between applying the herbicide and harvesting the beans was increased. The most abundant volatile compounds per percentage area belonged to the pyrazines, furans and phenols. The amount of glyphosate residue found in the beans exceeded the maximum detectable limit by the ELISA method regardless of the time between application and harvest, corresponding to values that are unacceptable to several purchasing countries, and making the samples unsuitable for export and a risk to food safety.
