Resumo: Cassava starch has many known applications in food, paper, glue and textile industries, including even biodegradable packaging. In small and medium industries, the starch is obtained by washing the peeled and grinded manioc roots, followed by leaving the washwater for settling before drying the concentrated slurry. Since starch particles are very fine and have a low density, their settling time is high, resulting in a batch operation that lasts for 18 to 24 h. Therefore, it becomes suitable to form larger and heavier starch sets by means of applying coagulants, allowing the particles to settle faster. In the work reported here, the natural coagulant M. oleifera seed extract was used to decrease the settling time of the cassava starch. The effect of the initial concentration of the particles and the coagulant content on the final sedimentation time was evaluated on the batch settling tests. The results showed that the use of the coagulant reduced the sedimentation time in a beaker from 14h to 2h, allowing a quick batch operation.

En las pequeñas y medianas industrias, el almidón se obtiene lavando la cáscara y moliendo la raíz de yuca, seguido de la separación del agua y el almidón por sedimentación, la pulpa concentrada se seca posteriormente. Dado que las partículas de almidón son muy finas y de baja densidad, los tiempos de sedimentación son altos, lo que resulta en lotes de aproximadamente 18 a 24 h. Sin embargo, el uso de coagulantes favorece la formación de grupos de partículas más grandes y pesados, lo que permite una sedimentación más rápida. En este trabajo, se usó un coagulante natural obtenido del extracto de semilla de Moringa oleifera LAM para reducir el tiempo de sedimentación del almidón de yuca. Se evaluó el efecto de la concentración inicial de las partículas y el contenido de coagulante en el tiempo de sedimentación final, a través de pruebas de sedimentación por lotes. Los resultados mostraron que el uso del coagulante redujo el tiempo de sedimentación en un vaso de precipitados de 14h a 2h, permitiendo una rápida operación por lotes.O amido de mandioca tem várias aplicações conhecidas nas áreas alimentícia, de papel, colas e indústria têxtil, incluindo embalagens biodegradáveis. Em pequenas e médias indústrias, o amido é obtido pela lavagem da casca e moagem da raiz da mandioca, seguida pela separação da água e do amido por sedimentação, sendo a polpa concentrada submetida posteriormente à secagem. Uma vez que as partículas de amido são muito finas e de baixa densidade, o tempo de sedimentação são altos, resultando em bateladas com cerca de 18 a 24 h. No entanto, o uso de coagulantes favorece a formação de aglomerados de partículas com maior tamanho e mais pesados, permitindo uma sedimentação mais rápida. Neste trabalho, um coagulante natural obtido do extrato de semente de M. oleifera LAM foi utilizado na redução do tempo de sedimentação do amido de mandioca.  Foi avaliado o efeito da concentração inicial das partículas e do teor de coagulante sobre o tempo final de sedimentação por meio de testes de sedimentação batelada. Os resultados mostraram que o uso do coagulante reduziu o tempo de sedimentação em proveta de 14h para 2h, permitindo uma rápida operação em batelada. Research, Society and Development2020-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/316910.33448/rsd-v9i5.3169Research, Society and Development; Vol. 9 No. 5; e28953169Research, Society and Development; Vol. 9 Núm. 5; e28953169Research, Society and Development; v. 9 n. 5; e289531692525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/3169/5380Copyright (c) 2020 Amarílis Severino Souza, Kassia Graciele Santosinfo:eu-repo/semantics/openAccessSouza, Amarílis Severino eSantos, Kassia Graciele dos2020-08-20T18:06:36Zoai:ojs.pkp.sfu.ca:article/3169Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:28.144830Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
