Item Cocriação de valor na cadeia do café especial: o movimento da terceira onda do café(Fundação Getulio Vargas, Escola de Administração de Empresas de São Paulo, 2018) Boaventura, Patricia Silva Monteiro; Abdalla, Carla Caires; Araújo, Cecilia Lobo; Arakelian, José SarkisO Brasil participa em aproximadamente 29% da exportação mundial de café, sendo 15% de “café especial”. A maior parte da exportação é composta por café commodity, influenciando a orientação da cadeia de valor por um paradigma de troca. Esse cenário tem mudado com a introdução de cafeterias especializadas, cápsulas para consumo domiciliar e demanda por um produto mais artesanal. Um paradigma de criação de valor ao longo da cadeia passa a impulsionar processos de produção, com objetivo não apenas de diferenciação por meio de grãos e processos superiores, mas também de experiências únicas construídas. Este artigo foi desenvolvido por meio de análise de conteúdo de 15 anos de notícias de dois jornais brasileiros. Além disso, foram entrevistados proprietários de cafeterias, produtores de café, cooperativas, intermediários e reguladores. Concluímos que a cadeia de valor passa por desafios para atingir uma mudança com objetivo de maior geração de valor em uso para todos os envolvidos.Item Influence of flowering and additional fertilization on physical and sensory aspects of arabica coffee(Universidade Federal Rural de Pernambuco, 2019) Rocha, Richardson Sales; Simão, João Batista Pavesi; Peluzio, João Batista Esteves; Ferrari, Jeferson Luiz; Gravina, Geraldo de AmaralIn Caparaó region, Brazil, in areas above 1000 m high, a second flowering (called late or from March) is common to take place, causing changes in the crop management for those intending to produce specialty coffees. The objective of this study was to evaluate physical and sensory aspects of arabica coffee from the Caparaó region, produced in traditional and late plantations in the same fields, using two fertilization regimes, one recommended by specific literature and another with the addition of extra fertilizers (33%), respecting the proportions amid them. The employed factorial analysis allowed identifying the interaction between the two levels of nutrition and the two harvests, for the analyzed attributes. The extra addition of fertilizers provided a reduction in the mean score of the fragrance/aroma and overall sensory attributes in the traditional harvest; and in the late harvest, it alone was responsible for raising the scores of the following sensory attributes: flavor, aftertaste, acidity, balance and total. The added extra amount of fertilizer, unassisted, altered the coffee physical aspects, reducing their defects/imperfections.Item Racionalidade limitada e oportunismo na cadeia do café: impactos nas formas contratuais do consórcio agrícola de fazendas especializadas(Universidade Federal de Lavras, 2006-07) Ferreira, Gabriel Murad Velloso; Waquil, Paulo Dabdab; Gonçalves, Wilson MagelaO presente trabalho objetivou analisar os impactos do comportamento oportunista e da racionalidade limitada na forma contratual adotada pelo Consórcio Agrícola de Fazendas Especializadas (C.A.F.E). Para isso, realizou-se um estudo de caso, no intuito de abranger as características mais importantes do tema, bem como seu processo de desenvolvimento. O referencial teórico que sustentou a pesquisa foi a Economia dos Custos de Transação (ECT). Mediante a análise das variáveis abordadas pela ECT, mais especificamente os pressupostos comportamentais (racionalidade limitada, oportunismo) e formas contratuais, concluiu-se que, no caso estudado, a existência do oportunismo interfere de certo modo na confiança, aumentando os custos de transação. No mesmo sentido, a assimetria informacional reforça a limitação da racionalidade dos agentes e, portanto, aumenta os custos de transação. Isso deixa clara a importância destes elementos na definição da forma contratual. Verificou-se a necessidade de uma estrutura contratual formalizada mais especificada e detalhada para que se possam reduzir os custos de transação gerados pela possibilidade de ações oportunistas e pela racionalidade limitada dos agentes. De acordo com as características observadas no Consórcio, a forma contratual mais adequada é a relacional, em que o ponto de referência principal é a própria relação entre as partes, mantendo-se a autonomia entre elas. A confiança e a reputação são elementos relevantes.Item A terceira onda do café em Minas Gerais(Universidade Federal de Lavras, 2016-07) Guimarães, Elisa Reis; Castro Júnior, Luiz Gonzaga de; Andrade, Helga Cristina Carvalho deConsidera-se que existam três movimentos, também denominados “ondas”, influenciando o mercado e o consumo mundiais de café. Cada um apresenta um conjunto diversificado de prioridades e filosofias, contribuindo de formas diferentes para a experiência de consumo da bebida. No Brasil, a Terceira Onda ganhou força nos últimos cinco anos, o que pode contribuir significativamente para a melhoria de qualidade dos cafés consumidos no país. Objetivou-se compreender como a Terceira Onda do café se faz presente nas estratégias de cafeterias no estado de Minas Gerais, por meio de entrevistas semiestruturadas em profundidade com proprietários de três cafeterias mineiras, baseadas no conceito de Terceira Onda e localizadas em cidades de portes variados. Observou-se grande adesão destas empresas aos princípios deste movimento, mas com adoção de duas posturas distintas, de purismo e transição. Concluiu-se que tais posturas podem ser influenciadas por diversos fatores e contribuir de formas diferentes para o consumo de cafés especiais no Brasil.Item Characterization of beverage quality in Coffea canephora Pierre ex A. Froehner(Editora UFLA, 2018-04) Souza, Carolina Augusto de; Rocha, Rodrigo Barros; Alves, Enrique Anastácio; Teixeira, Alexsandro Lara; Dalazen, Janderson Rodrigues; Fonseca, Aymbiré Francisco Almeida daDifferentiation of coffee according to its quality can result in added value. Both the coffee genotype and the environment influence beverage quality. The main species grown in the Amazon region is C. canephora, which includes two distinct botanical varieties: Conilon and Robusta. The aim of this study was to characterize beverage quality in C. canephora and distinguish the Conilon and Robusta botanical varieties and intervarietal hybrids. We evaluated the beverage quality of 130 superior clones from samples of hulled coffee collected in the experimental field of Embrapa Rondônia in the municipality of Ouro Preto do Oeste, RO, Brazil. The beverage was classified according to the Robusta Cupping Protocols, which also considers the nuances of the beverage, described as neutral, fruit-like, exotic, refined, and mild. The final mean values classified the Robusta botanical variety and the intervarietal hybrids as coffees with a premium beverage, and the Conilon botanical variety as usual good quality. The nuances of the Conilon botanical variety were found to be predominantly neutral (78%), as compared to the Robusta botanical variety and the intervarietal hybrids, which exhibited 50% and 44% of their beverages, respectively, with fruit-like, exotic, or mild nuances. The genetic parameters indicate that the genetic component was more important than the environmental in expression of coffee quality attributes. Genetic variability was observed in the population evaluated, except for the Uniform Cup and Clean Cup beverage attributes.Item Competitive pressures on the artisan coffee roaster segment in the state of Minas Gerais, Brazil: a multi-case study(Editora UFLA, 2018-04) Guimarães, Elisa Reis; Andrade, Helga Cristina Carvalho de; Cozadi, Álvaro dos Reis; Antonialli, Luiz Marcelo; Santos, Antônio Carlos dosThe specialty coffee market is still little known and underexplored in Brazil, motivating an analysis of the competitive pressures and structure of the artisan coffee roaster segment in the state of Minas Gerais, in order to better understand it and encourage the adoption of specific policies for its expansion, besides comparing it to the commodity coffee roasting segment. A multi-case study was performed with three companies in this segment through in-depth interviews with their owners. There were significant changes in the competitive forces that shape the coffee industry, when comparing the specialty and commodity coffee segments, both in intensity and in motivations. Among the suggested policies to support the specialty coffee segment are its promotion and dissemination through “consumer education” and awareness raising on the differentiated properties of these products, besides providing subsidized courses and specializations for those who wish to be involved in this marketplace.Item Quality of natural coffee dried under different temperatures and drying rates(Editora UFLA, 2018-04) Borém, Flávio Meira; Isquierdo, Eder Pedroza; Alves, Guilherme Euripedes; Ribeiro, Diego Egídio; Siqueira, Valdiney Cambuy; Taveira, Jose Henrique da SilvaThe final quality of coffees depends on the preservation of the cell membranes of the coffee beans, which can be damaged during the drying. Thus, the aim of this study was to assess the immediate and latent effects of the air temperature and drying rate on the sensorial quality of natural coffees, as well as its relationship with the chemical e physiological characteristics of the coffee beans. Mature fruits of arabica coffee were harvested and sundried to moisture content of approximately 35% (wb) and then moved into a mechanical drier under different conditions of drying. This process involved the combination of three dry bulb temperatures – DBT (35°C, 40°C, and 45°C) and two dew point temperatures – DPT (2.6°C and 16.2°C). Thus, the relative humidity of the air used for drying was a dependent variable of DTB and DPT, and as consequences, different drying rates were achieved for each DBT. The increase in the drying rate for the temperatures 35°C and 40°C has a negative effect on the final quality of natural coffee beans. However, for the temperature of 45°C, the effects of the drying rate on the coffee beans are overlaid by the thermal damages that are caused at this level of heating. Higher sensory scores for coffee are linked to lower values of electrical conductivity and potassium leaching of the exudate of the coffee beans, as well as lower values of fatty acids. It is emphasized that while the temperature of 35o C is recommended for the production of specialty coffees the temperature of 45o C is not.Item Sensory analysis and chemical composition of ‘bourbon’ coffees cultivated in different environments(Editora UFLA, 2018-01) Figueiredo, Luisa Pereira; Borém, Flávio Meira; Ribeiro, Fabiana Carmanini; Giomo, Gerson Silva; Malta, Marcelo Ribeiro; Taveira, José Henrique da SilvaGiven the growing participation and appreciation of specialty coffees in the international market, coupled to the intrinsic quality of cultivar Bourbon for the production of differentiated coffees and the environmental diversity of Brazil, this study was conducted, with the objective to evaluate how the interaction between ‘Bourbon’ genotypes and different environments affect the sensory quality of coffees, besides relating the chemical composition (trigoneline, 5-CQA and caffeine) of beans with their sensory profile. Four Arabica coffee genotypes were evaluated: one of them is widely grown in Brazil (Mundo Novo) and three belong to the group of cultivar Bourbon. The genotypes were evaluated in a field experiment, in Lavras, MG; Santo Antônio do Amparo, MG and São Sebastião da Grama, SP. Thelatter was the most promising environment for the production of specialty coffees. Genotypes Yellow Bourbon IAC J9 and Yellow Bourbon/SSP were the most suitable for the production of specialty coffees. Regardless of culture environment, the genotype Yellow Bourbon/CM is not suitable for the production of specialty coffees. Caffeine content enabled coffee differentiation regarding beverage quality. Coffees with superior quality have lower caffeine contents. The content of 5-CQAallowed to differentiate environments.Item Sensorial characteristics of coffee (Coffea arabica L.) varieties in the Alto Paranaíba region(Editora UFLA, 2013-01) Chalfoun, Sara Maria; Pereira, Marcelo Cláudio; Carvalho, Gladyston Rodrigues; Pereira, Antonio Alves; Taciana Villela Savian; Botelho, Deila Magna dos SantosThe objective of this study was to verify the sensorial characteristics of grains of 21 Coffea arabica L. cultivars obtained from EPAMIG Experimental Farm in Patrocínio, Minas Gerais, in the Alto Paranaíba Region. The coffee cherries were husked and dried in wooden trays, until 11 to 12% humidity and sent to three Brazilian Specialty Coffee Association BSCA accredited professional coffee tasters. The data were statistically evaluated by multivariate analysis to compare the cultivars and group them. The following cultivars, listed in decreasing order according to the first principal component with scores above 80 points, thus considered to produce superior beverage based on the attributes with the highest scores (flavor, sweetness, balance, acidity, clean beverage and aspect), for the two methods, during the two –year study was cultivar H419-6- 2-5-2. The ascendancy of the cultivars and progenies tested, whether derived or not from the Timor Hybrid, did not affect their qualitative performance.
