Resumo: | The kombucha tea is a beverage resulting from the fermentation of sweetened green and/or black tea and added to a culture containing a symbiotic consortium of bacteria and yeasts, thus presenting an antimicrobial and antioxidant character. The fermentation of kombucha tea takes place at room temperature, over a period of 3 to 60 days. At the end of fermentation, the beverage is a cocktail of chemical components, organic acids, fiber, and ethanol. Studies show that the regular consumption of the beverage prevents several diseases, strengthening the immune system, benefits which are related to the presence of polyphenols, gluconic acid, amino acids, antibiotics, among other micronutrients generated during fermentation. Therefore, the present work aimed at producing kombucha tea using green tea as a substrate on a laboratory scale, evaluating the physicochemical properties, bioactive compounds and antioxidant activity of kombucha tea in order to characterize it. The analyses performed were pH, total soluble solids (TSS), titratable acidity (TA), ratio (TSS/TA), coloration in the parameters (L*, a* and b*), antioxidants DPPH, ABTS and polyphenols. From the results obtained, in its physical-chemical characterization, it was observed a decrease in the pH and SST value due to the presence of organic acids and sucrose used as a fermentative substrate. Furthermore, the results of bioactive compounds and antioxidant activity are related to the extraction of compounds from green tea under the conditions used on a laboratory scale, and that the resulting beverage presented characteristics similar to those evaluated by other authors. Therefore, this study encourages scientific research on this beverage, kombucha is still mainly produced through natural fermentation processes, and therefore uncontrolled. |

La fermentación del té de kombucha tiene lugar a temperatura ambiente durante un periodo de 3 a 60 días. Al final de la fermentación, la bebida es un cóctel de componentes químicos, ácidos orgánicos, fibras y etanol. Los estudios demuestran que el consumo regular de la bebida previene diversas enfermedades, fortaleciendo el sistema inmunológico, beneficios que están relacionados con la presencia de polifenoles, ácido glucónico, aminoácidos, antibióticos y otros micronutrientes generados durante la fermentación. Por lo tanto, el presente trabajo tuvo como objetivo producir té de kombucha utilizando té verde como sustrato a escala de laboratorio, evaluando las propiedades fisicoquímicas, los compuestos bioactivos y la actividad antioxidante del té de kombucha para caracterizarlo. Los análisis realizados fueron el pH, los sólidos solubles totales (SST), la acidez titulable (AT), la relación (SST/TA), la coloración en los parámetros (L*, a* y b*), los antioxidantes DPPH, ABTS y los polifenoles. A partir de los resultados obtenidos, en su caracterización físico-química, hubo una disminución en el valor de pH y SST debido a la presencia de ácidos orgánicos y sacarosa utilizada como sustrato fermentativo. Además, los resultados de los compuestos bioactivos y la actividad antioxidante están relacionados con la extracción de los compuestos del té verde en las condiciones utilizadas a escala de laboratorio, y que la bebida resultante presentó características similares a las evaluadas por otros autores. Por lo tanto, este estudio estimula la investigación científica sobre esta bebida, ya que la kombucha sigue produciéndose principalmente mediante procesos de fermentación natural y, por tanto, sin control.O chá de kombucha é uma bebida resultante da fermentação de chá verde e/ou preto adocicados e adicionados de uma cultura contendo um consórcio simbiótico de bactérias e leveduras, apresentando dessa forma, um caráter antimicrobiano e antioxidante. A fermentação do chá de kombucha ocorre a temperatura ambiente, em um período de 3 a 60 dias, ao final da fermentação, a bebida é um coquetel de componentes químicos, ácidos orgânicos, fibras e etanol. Estudos comprovam que o consumo regular da bebida previne diversas doenças, fortalecendo o sistema imunológico, benefícios os quais estão relacionados à presença de polifenóis, ácido glucônico, aminoácidos, antibióticos entre outros micronutrientes gerados durante a fermentação. Diante disso, o presente trabalho teve como objetivo a produção do chá de kombucha utilizando o chá verde como substrato em escala laboratorial, avaliando-se as propriedades físico-químicas, compostos bioativos e atividade antioxidante do chá de kombucha, a fim de caracterizá-lo. As análises realizadas foram pH, sólidos solúveis totais (SST), acidez titulável (AT), ratio (SST/AT), coloração nos parâmetros (L*, a* e b*), antioxidantes DPPH, ABTS e polifenóis. A partir dos resultados obtidos, em sua caracterização físico-química, observou-se um decréscimo do valor de pH e SST devido a presença de ácidos orgânicos e a sacarose utilizada como substrato fermentativo. Além disso, os resultados de compostos bioativos e atividade antioxidante estão relacionados com a extração dos compostos do chá verde nas condições utilizadas em escala laboratorial, além de que a bebida resultante apresentou características semelhantes a avaliadas por demais autores. Diante disso, este estudo estimula a pesquisa científica sobre esta bebida, visto que o kombucha ainda é produzido principalmente por meio de processos de fermentação natural, e, portanto, não controlados.Research, Society and Development2021-12-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2299210.33448/rsd-v10i15.22992Research, Society and Development; Vol. 10 No. 15; e576101522992Research, Society and Development; Vol. 10 Núm. 15; e576101522992Research, Society and Development; v. 10 n. 15; e5761015229922525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/22992/20592Copyright (c) 2021 Ana Paula Dada; Anderson Lazzari; Andresa Caroline de Oliveira Cestário; Dario Sousa da Silva; Bianka Rocha Saraiva; Cássia Inês Lourenzi Franco Rosa; Paula Toshimi Matumoto-Pintrohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDada, Ana PaulaLazzari, AndersonCestário, Andresa Caroline de Oliveira Silva, Dario Sousa da Saraiva, Bianka Rocha Rosa, Cássia Inês Lourenzi Franco Matumoto-Pintro, Paula Toshimi2021-12-06T10:13:53Zoai:ojs.pkp.sfu.ca:article/22992Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:59.754507Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
