Efeitos da fermentação nas propriedades físico-químicas e nutricionais do farelo de arroz

Abstract: .br *A quem a correspondência deve ser enviada ResumoO objetivo deste trabalho foi avaliar a disponibilização de nutrientes no farelo de arroz através de um processo de fermentação utilizando Saccharomyces cerevisiae como inóculo, bem como caracterizar os farelos não fermentado e fermentado química e nutricionalmente. Os parâmetros definidos para a fermentação foram 3% de levedura, 30% de umidade e um intervalo de 6 horas a 30 °C. A caracterização físico-química foi realizada segundo AOAC (2000), a digestibili… Show more

“…This result is consistent with some researchers who reported an increase in ash content by 30%, 47.8%, and 10.5% [35,38,45]. Increased ash content is thought to result from the growth of hypha and mycelium Rhizopus oryzae on the rice bran.…”

“…At the end of 15, 30, 45 and 60 minutes, the absorbance was measured at 515 nm and the ability of scavenging the radical was expressed as inhibition percentage according to the Equation 3 (Souza et al 2009). Table 1 presents the variation in rice bran composition during the fermentation with R. oryzae CCT 7560 The variation in the contents of ashes in unfermented and fermented biomass was similar to that reported by Feddern et al (2007), which after 6 h of fermentation with Saccharomyces cerevisiae obtained 10.5% of ashes. In this work, the maximum ash content was after 72 h fermentation (14.7%).…”
