Resumo: | A pilot system for the application of microwaves to foods, with a frequency of 2.45 GHz, and microwave powers ranging from 100 W to 3000 W was used to evaluate the effects of this technology on physical, physicochemical and rheological characteristics of wheat grains, wheat flour and their respective gluten. Wheat samples (600 g per treatment) were conditioned to moisture of 23% and exposed to microwaves in the powers of 100 W, 450 W and 750 W (TM 1, TM 2 and TM 3, respectively) until it reached 16 % and had their characteristics compared with control wheat (TC), without treatment. The results of milling yield and specific volume of grains did not show significant differences (p≤0.05). These wheats were ground, generating flours FM 1, FM 2, FM 3 and FC (from TM1, TM 2, TM 3 and TC, respectively). The results of wheat flour damaged starch from wheat-treated and FC showed no significant difference between their averages. Flours FM1, FM 2 and FM 3 showed significant reductions in the values of wet and dry gluten, when compared to the FC, but their gluten indexes were not statistically different. With the exception of the paste temperature, other pasting properties (maximum viscosity, minimum viscosity, breakdown and final viscosity) were significantly different, at the level of 5% significance, and presented a progressive behavior of the viscosity profile. The size distribution of the particle, accumulated at 90%, for flours FM 1, FM 2 and FM 3 were larger than the accumulated flour of FC and different significantly, confirmed by the higher values of their mean diameters (d4,3). The polydispersity of the particles (Span), ranged from 1.81 to 1.94, and there was no significant difference between all samples, however due to the value obtained being greater than 1, this indicates that the samples are polydispersed. |

Las muestras de trigo (600g por tratamiento) fueron acondicionadas a una humedad de 23% y luego expuestas en las potencias de microondas de 100 W, 450 W y 750 W (TM 1, TM 2 y TM 3, respectivamente) hasta llegar a 16%, siendo comparadas con un control de trigo (TC) sin tratamiento. Los resultados del rendimiento de moliendas y el volumen especifico de los granos no presentaron diferencias significativas (p≤0,05). Luego, estos trigos fueron molidos generando las harinas FM1, FM 2, FM3 y FC (provenientes de TM1, TM2, TM3 y TC, respectivamente). Los resultados sobre el almidón dañado de las harinas de trigo tratadas por microondas y FC no presentaron diferencias significativas en sus promedios. Las harinas FM 1, FM 2, y FM 3 mostraron una reducción significativa en sus valores de gluten húmedo y seco en comparación con FC, sin embargo, sus índices de gluten no se mostraron estadísticamente diferentes. Excepto la temperatura de pasta, las demás propiedades de pasta (viscosidad máxima, viscosidad mínima, quiebra y viscosidad final) presentaron diferencias significativas, a un nivel de significancia de 5%, y un comportamiento progresivo del perfil de viscosidad. La distribución del tamaño promedio de partículas acumulada al 90%, para las harinas FM 1, FM 2 y FM 3 fueron mayores a las de la harina FC, y diferentes significativamente, siendo confirmado por los mayores valores de sus diámetros medios (d4,3). La polidispersibilidad de las partículas (Span), varió entre 1.81 y 1.94, no presentando diferencias significativas entre todas las muestras, no obstante, debido a que el valor obtenido fue superior a 1, este indica que las muestras son polidispersas.Um sistema piloto para aplicação de micro-ondas em alimentos, de frequência de 2,45 GHz, e capacidade de geração de micro-ondas com potências que variam de 100 W a 3000 W foi utilizado para avaliar os efeitos desta tecnologia nas características físicas, físico-químicas e reológicas dos grãos de trigo, farinha de trigo e seus respectivos glútens. Amostras de trigo (600 g por tratamento) foram condicionadas até a umidade de 23 % e expostas às micro-ondas nas potências de 100 W, 450 W e 750 W (TM1, TM 2 e TM 3, respectivamente) até que esta atingisse 16 % e tiveram suas características comparadas com o trigo controle (TC), sem tratamento. Os resultados de rendimento de moagem e volume específico dos grãos não apresentaram diferenças significativas (p≤0,05). Estes trigos foram moídos, gerando as farinhas FM 1, FM 2, FM 3 e FC (provenientes de TM1, TM 2, TM 3 e TC, respectivamente). Os resultados de amido danificado das farinhas dos trigos tratados por micro-ondas e a FC não apresentaram diferença significativa entre as suas médias. As farinhas FM1, FM 2 e FM 3 mostraram reduções significativas nos valores de glúten úmido e seco, quando comparadas com a FC, porém seus índices de glúten não se mostraram diferentes estatisticamente. Com exceção da temperatura de pasta, as demais propriedades de pasta (viscosidade máxima, Viscosidade mínima, quebra e viscosidade final) apresentaram-se diferentes significativamente, ao nível de 5 % de significância, e um comportamento progressivo do perfil de viscosidade. A distribuição do tamanho médio das partículas acumulada à 90%, para as farinhas FM 1, FM 2 e FM 3 foram maiores que a acumulada da farinha FC e diferentes significativamente, sendo confirmado pelos maiores valores dos seus diâmetros médios (d4,3). A polidispersibilidade das partículas (Span), variou de 1,81 a 1,94, e não apresentou diferença significativa entre todas as amostras, porém devido ao valor obtido ter sido superior a 1, este indica de que as amostras são polidispersas.Research, Society and Development2021-07-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1703310.33448/rsd-v10i8.17033Research, Society and Development; Vol. 10 No. 8; e12610817033Research, Society and Development; Vol. 10 Núm. 8; e12610817033Research, Society and Development; v. 10 n. 8; e126108170332525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17033/15304Copyright (c) 2021 Flávio Martins Montenegro; Raquel Bragatto Heffernan; Antonio Marsaioli Junior; Michele Nehemy Berteli; Pedro H.
