Desafios da mulher na cafeicultura Grupo Cafeína COCATREL, Três Pontas - MG
Archanjo, Larissa Evely; Brigante, Giselle Prado
A região do Sul de Minas é reconhecida mundialmente pela produção rural, principalmente a produção cafeeira, de importância econômica regional e nacional, para o agronegócio. No entanto, o papel da mulher na cafeicultura contribui notavelmente para o crescimento do cenário de produção rural. Assim, o presente estudo considerou pesquisar sobre a inserção feminina no mercado, averiguando as comparações de gênero e a atuação da mulher na atualidade, na cadeia produtiva. Inicialmente, foi realizada uma busca exploratória, através da investigação de artigos científicos publicados online, para embasamento desta discussão. Utilizou-se como método uma pesquisa descritiva e qualitativa, a partir de questionário estruturado e composto por questões de múltipla escolha direcionada as mulheres produtoras rurais, empresárias do ramo, técnicas que compõem o Grupo Cafeína (COCATREL), da cidade de Três Pontas, Minas Gerais. Fizeram parte do questionário perguntas que envolveram os desafios das mulheres na cafeicultura, como a remuneração mensal, maternidade e inseguranças. Ao analisar os dados obtidos, com apoio de ferramentas e autores selecionados, foi possível discutir e apresentar um material para a discussão sobre a equidade de gênero no campo. E assim proporcionar um trabalho com o intuito de produzir resultados relevantes e promover um estudo científico para o entendimento da atuação das mulheres na produção rural local, no presente e no futuro das próximas gerações. Com a pesquisa pôde-se perceber que ainda existe uma insatisfação com as condições encontradas no mercado de trabalho e uma expressiva discriminação.

A mixed model applied to joint analysis in experiments with coffee blends using the least squares method

The aim of the present study was to propose a mixed model for a sensory analysis of four experiments with blends of different standards of quality, including the species Coffea Arabica L. and Coffea Canephora. Each experiment differed in the proportions used to formulate the blends and the concentrations used in preparing the beverages, these being 7% and 10% coffee powder for each 100 ml of water. The response variables under analysis were the sensory characteristics of the beverage found in an assessment made by a group of trained tasters, considering taste, bitterness and a final score. Each description followed a numerical rating scale of intensity that ranged from 0 to 10. The model was implemented using the least squares method; this led to the conclusion that including random parameters in the model, represented by the experiments, made it possible to compare the effect of each component simultaneously for each of the experiments.

Monte Carlo simulation and importance sampling applied to sensory analysis validation of specialty coffees

Coffee sensory analysis is usually made by a sensory panel, which is formed by trained tasters, following the recommendations of the Specialty Coffee Association of America. However, the preference for a coffee is commonly determined by experimentation with consumers, who typically have no special skills in terms of sensory characteristics. Therefore, this study aimed at applying an intensive computational method to study sensory notes given by an untrained sensory panel, considering the probability distributions of the class of extreme values. Four types of specialty coffees produced under different processes and in varied altitudes in the mountainous region of Mantiqueira, Minas Gerais, were considered. We concluded that the generalized Pareto distribution can be applied to sensory analysis to discriminate types of specialty coffees. Furthermore, the method of importance sampling by Monte Carlo simulation showed greater variability considering a probabilistic model adjusted to identify specialty coffees.

The intrinsic characteristics of the vegetative propagule may influence the rooting speed and shoot growth, as well as the final physiological quality of clonal seedlings of Coffea canephora. The aim of this study was to evaluate the growth and physiological quality of ‘Robusta’ coffee seedlings produced from propagules (stem cuttings) with different cutting ages. The study was conducted in a greenhouse, in the district of Ouro Preto do Oeste, in Rondônia, Brazil (10˚45’43” S and 62˚15’10” W). The ages of the cuttings were 30, 60, 90, 120 and 150 days, corresponding to five positions on the secondary orthotropic stem (sprout), from the apex to the base. Dry matter accumulation, and relative and absolute growth rates were evaluated for 188 days after cutting, as well as the vegetative characteristics of the seedlings at 125 days after cutting. It appears that growth can be divided into three phases: 1) Initial: slow growth, lasting approximately 83 days; 2) Intermediate: fast growth, lasting approximately 40 days; and 3) Final: slow growth, starting approximately 125 days after cutting. With physiological quality, although all the cuttings showed similar growth curves, those of 60, 90 and 120 days produced, 125 days after cutting, the best vegetative performance in the seedlings.
