Physical-chemical characterization of pre-cooked mixed rice flour and barley bagasse

Abstract: The extrusion processing parameters, chemical composition and water content of the flour mixture may affect the structure of rice flour, leading to products with different rheological behavior and hygroscopicity. Therefore, this work aimed to study the rheological properties and water adsorption of mixed flours of broken rice and barley bagasse obtained by extrusion cooking. Samples were prepared from a mixture of grits/bagasse between 82/18 and 73/27 (w/w) with water content between 18.04 and 26.96%, using a … Show more

“…The most frequent use of rice residues is as a fertilizer additive and in plants in the production of thermal and electrical energy (Abaide et al, 2019). Applications of residues were also found in the coproduction of furfural, furfuryl alcohol and formic acid , fertilizer (Jakelaitis et al, 2010), milk coagulation enzymes (Alecrim et al, 2015), flour (Ascheri et al, 2016) andvermicomposting (Vione et al, 2018).…”

“…A viscosidade inicial a frio (Vinicial) está relacionada com o alto grau de cisalhamento mecânico que expõe os agrupamentos hidrofílicos que apresentam grande afinidade pela água, ocasionado pela perda da integridade dos grânulos de amido e da cristalinidade interna (ASCHERI et al, 2016). Sendo assim, quando se nota uma baixa Vinicial pode-se entender que o processo de extrusão não causou danos mecânicos suficientes aos grânulos de amido nas farinhas mistas, impedindo a absorção de água pelos grânulos de amido e o seu consequente intumescimento (tabela 1 e 2).…”

“…This process promotes the disruption of the granular structure of starch, denaturing and re-directing proteins to form a final product with modified physical characteristics. Due to the changes in the raw material imposed by the extrusion cooking process, it is important to understand the water absorption properties (ASCHERI et al, 2016).…”
