Resumo: | The objective of this study was to evaluate the influence of coffee cultivation at different altitudes associated with the type of fruit processing on the diversity and density of the yeast population and on the chemical and sensorial quality of the final beverage. The experiment was conducted at Fazenda Segredo, in the municipality of Cristais, Minas Gerais, with samples of coffee harvested from plots of the Mundo Novo variety. After the samples were harvested, the coffee beans were separated into cherry varieties, and the beans were subjected to natural drying on a terrace and anaerobic fermentation in drums for 36 hours. The experimental design used was a randomized block design, in a 3x2 factorial scheme, with three repetitions per treatment. The yeast density was measured by means of the serial dilution technique and the diversity was given by the Shannon-Wiener index (H'). The classification of the beans followed the Technical Rules of Identity and Quality for the Classification of Raw Beneficiated Coffee and the sensorial analysis was done according to the Specialty Coffee Association (SCA) methodology, by judges certified by the Association. The coffee culture at the altitude of 845 meters associated with the process of anaerobic fermentation showed the highest rate of density and diversity of yeasts in the grain and the distinct sensory characteristics, resulting in a drink with differentiated flavor. |

El experimento se realizó en la Fazenda Segredo, en el municipio de Cristais, Minas Gerais, con muestras de café cosechadas en parcelas de la variedad Mundo Novo. Tras la recolección de las muestras, los granos de café se separaron en variedades de cereza y se sometieron a un secado natural en una terraza y a una fermentación anaeróbica en bidones durante 36 horas. El diseño experimental fue en bloques aleatorios, en un esquema factorial 3x2, con tres repeticiones por tratamiento. La densidad de las levaduras se midió mediante la técnica de dilución en serie y la diversidad vino dada por el índice de Shannon-Wiener (H'). La clasificación de los granos siguió las Normas Técnicas de Identidad y Calidad para la Clasificación del Café Beneficiado Crudo y el análisis sensorial se realizó según la metodología de la Asociación de Cafés Especiales (SCA), por jueces certificados por la Asociación. El cultivo de café a la altitud de 845 metros asociado al proceso de fermentación anaeróbica presentó la mayor densidad y tasa de diversidad de levaduras en el grano y características sensoriales diferenciadas, dando lugar a una bebida con sabor diferenciado.O objetivo deste estudo foi avaliar a influência do cultivo de café em diferentes altitudes associado ao tipo de processamento dos frutos na diversidade e densidade da população de leveduras e na qualidade química e sensorial da bebida final. O experimento foi conduzido na Fazenda Segredo, no município de Cristais, Minas Gerais, com amostras de café colhidas em talhões da variedade Mundo Novo. Após a colheita das amostras, foi realizada a separação dos grãos de café em cereja e os tratamentos de seca natural em terreiro e fermentação anaeróbica em tambores por 36 horas. O delineamento experimental utilizado foi em blocos casualizados, em esquema fatorial 3x2, com três repetições por tratamento. A densidade de leveduras foi medida por meio da técnica de diluição seriada e a diversidade dada pelo Índice de Shannon-Wiener (H’). A classificação dos grãos seguiu o Regulamento Técnico de Identidade e Qualidade para a Classificação do Café Beneficiado Cru e a análise sensorial feita segundo a metodologia Specialty Coffee Association (SCA), por juízes certificados pela mesma. A cultura do café na altitude de 845 metros associada ao processo de fermentação anaeróbica apresentou a maior taxa de densidade e diversidade de leveduras no grão e as características sensoriais distintas, resultando em uma bebida de sabor diferenciado.Research, Society and Development2022-10-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3490510.33448/rsd-v11i13.34905Research, Society and Development; Vol. 11 No. 13; e389111334905Research, Society and Development; Vol. 11 Núm. 13; e389111334905Research, Society and Development; v. 11 n. 13; e3891113349052525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/34905/29828Copyright (c) 2022 Gustavo Adolfo de Paula Souza; Tayla Évellin de Oliveira; Ligiane Aparecida Florentinohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Gustavo Adolfo de Paula Oliveira, Tayla Évellin de Florentino, Ligiane Aparecida 2022-10-17T13:43:46Zoai:ojs.pkp.sfu.ca:article/34905Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:50:01.259717Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
