Resumo: | The agricultural production of national coffee faces controversy regarding the quality of roasted and ground coffee, being susceptible to quality loss because of oxygen and humidity exposure and high storage temperatures. In light of the importance of coffee to the Brazilian economy and consumption, a survey was made of the main brands of coffee sold in establishments in the city of São Luís, observing the presence or absence of the ABIC quality seal, the category (traditional, extra-strong, superior, gourmet), and the most common packaging types (pillow and vacuum-sealed bags). Then, two purity parameters established by ABIC – humidity and fixed mineral residue – were determined quantitatively in the eight representative samples. The analyses were performed following the procedures described by the Adolf Lutz Institute (2008). The survey revealed that the superior and gourmet categories of coffee are not easily found, while traditional and extra-strong coffee is very accessible, both in pillow and vacuum-sealed bags. The moisture level results showed two brands (A2 and A3) within the standards established by INMETRO for coffee in both pillow and vacuum-sealed bags. Of the samples of fixed mineral residue that were collected, brand A1 was observed to be in conformity with legislation, for coffee packaged in both pillow and vacuum-sealed bags, and brand A4 showed results for pillow bags within the given parameters. Statistical design was applied to verify the effect of packaging (pillow and vacuum-sealed bag) on moisture levels between different brands using analysis of variance (ANOVA). The results showed that despite displaying the ABIC seal attesting to the quality of the product, without fraud and free of impurities, 50% of the samples analyzed showed alterations in moisture level and 62.5% showed fixed mineral residue levels above the standards established by Brazilian legislature. |

En vista de la importancia del café para la economía y el consumo brasileño, se realizó una encuesta de las principales marcas de café vendidas en los establecimientos de la ciudad de São Luís, observando la presencia o ausencia del sello de calidad ABIC, sus categorías (tradicional, extra fuerte, superior y gourmet) y los tipos de envasado más habituales (cojín y vacío). Luego, se determinaron cuantitativamente dos parámetros de pureza establecidos por ABIC - humedad y residuo mineral fijo - en las ocho muestras representativas. Los análisis se realizaron siguiendo los procedimientos descritos por el Instituto Adolf Lutz (2008). La encuesta reveló que las categorías de café premium y gourmet no se encuentran fácilmente, mientras que el café tradicional y extrafuerte es muy asequible, tanto en envasado al vacío como en cojín. os resultados del nivel de humedad mostraron dos marcas (A2 y A3) dentro de los estándares establecidos por INMETRO para café tanto en bolsas tipo almohada como en bolsas selladas al vacío. Para las muestras de contenido de residuos minerales fijos obtenidas, se observó que la marca A1 cumplía con la legislación, tanto para café envasado en cojín como en bolsa sellada al vacío, y la marca A4 arrojó resultados para los cojines dentro de los indicados parámetros. Se aplicó el proyecto estadístico para verificar el efecto del empaque (cojín y bolsa sellada al vacío) sobre los niveles de humedad entre las diferentes marcas mediante análisis de varianza (ANOVA). Los resultados mostraron que a pesar de exhibir el sello ABIC que acredita la calidad del producto, sin fraude y libre de impurezas, el 50% de las muestras analizadas presenta alteraciones en el nivel de humedad y el 62,5% presenta niveles fijos de residuos minerales por encima de los estándares establecidos por la legislatura brasileña.A produção agrícola do café nacional encara controvérsias quanto à qualidade do café torrado e moído, sendo suscetível à perda de qualidade pela exposição ao oxigênio e umidade e pela estocagem a temperaturas elevadas. Diante da importância do café para a economia e o consumo brasileiros, foi feito um levantamento das principais marcas de café comercializadas em estabelecimentos da cidade de São Luís, observando-se a presença ou ausência do selo de qualidade da ABIC, suas categorias (tradicional, extraforte, superior e gourmet) e tipos de embalagens mais comuns (almofada e a vácuo). Em seguida, dois parâmetros de pureza estabelecidos pela ABIC - umidade e resíduo mineral fixo - foram determinados quantitativamente nas oito amostras representativas. As análises foram realizadas seguindo os procedimentos descritos pelo Instituto Adolf Lutz (2008). A pesquisa revelou que as categorias de café superior e gourmet não são facilmente encontradas, enquanto o café tradicional e extra-forte é muito acessível, tanto na embalagem almofada quanto a vácuo. Os resultados obtidos para os teores de umidade demonstraram que duas marcas (A2 e A3) estão dentro dos padrões estabelecidos pelo INMETRO, tanto para cafés embalados em almofada quanto a vácuo. Para as amostras de teores de resíduo mineral fixo obtidos, observou-se que a marca A1 estava em conformidade com a legislação, tanto para o café acondicionado em almofada como em saquinho selado a vácuo, e a marca A4 apresentou resultados para as almofadas dentro dos parâmetros indicados. O projeto estatístico foi aplicado para verificar o efeito da embalagem (almofada e saco selado a vácuo) sobre os níveis de umidade entre as diferentes marcas por meio de análise de variância (ANOVA). Os resultados mostraram que apesar de apresentarem o selo ABIC atestando a qualidade do produto, sem fraude e livre de impurezas, 50% das amostras analisadas apresentaram alteração no teor de umidade e 62,5% apresentaram teores de resíduos minerais fixos acima dos padrões estabelecidos pela legislação brasileira.Research, Society and Development2021-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1463010.33448/rsd-v10i5.14630Research, Society and Development; Vol. 10 No. 5; e11810514630Research, Society and Development; Vol. 10 Núm. 5; e11810514630Research, Society and Development; v. 10 n. 5; e118105146302525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/14630/13229Copyright (c) 2021 Anna Karolyne Lages Leal; Ricardo Santos Silva; Elis Cristina de Sousa Ferreira; Raissa Soares Penha Ferreira; Maria do Socorro Nahuz Lourençohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLeal, Anna Karolyne Lages Silva, Ricardo Santos Ferreira, Elis Cristina de Sousa Ferreira, Raissa Soares Penha Lourenço, Maria do Socorro Nahuz 2021-05-17T18:20:49Zoai:ojs.pkp.sfu.ca:article/14630Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:42.128191Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
