Resumo: The objective of this study was to identify the type and quantity of fibres present in rice bran. Samples of fresh rice bran were analysed by Acid Detergent Fibre Method (NDA) and Neutral Detergent Fibre Method (NDF). The results showed that rice bran has in its fibre composition high levels of N. D. F. (27,4%), predominating the contents of hemicelluloses (17.3%) and lignin (20.9%). On the other hand, the value obtained for cellulose (2.64%) was smallerthan that reported in literature. The informations of this study show that rice bran has high concentration of insoluble fibres, such as hemicelluloses and lignin, which may play an important protective role against colonic carcinogenesis.

Amostras em triplicata de farelo de arroz fresco, fornecido pela máquina de beneficiamento ARAWAL de Botucatu, foram analisadas pelos Métodos de Fibra Detergente Ácido (FDA) e Fibra Detergente Neutro (FDN). As amostras analisadas apresentaram níveis elevados de FDN (27,4%), predominando os conteúdos de hemiceluloses (17,3%) e lignina (20,9%). Por outro lado, o conteúdo de celulose (2,64%) foi menor do que relatado na literatura. Os dados do presente estudo demonstram que o farelo de arroz possui alta concentração de fibras, predominando as do tipo insolúvel como hemiceluloses e lignina, as quais atuam como protetoras no desenvolvimento de câncer de cólon.Núcleo de Editoração – PUC-Campinas1994-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9098Brazilian Journal of Nutrition; Vol. 7 No. 1 (1994): Revista de NutriçãoRevista de Nutrição; Vol. 7 Núm. 1 (1994): Revista de NutriçãoRevista de Nutrição; v. 7 n. 1 (1994): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPporhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9098/6485Copyright (c) 2023 Luiza Cristina Godim Domingues DIAS, Félix REYES, João Lauro Viana de CAMARGO, Maria Aparecida Marchesan RODRIGUEShttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDIAS, Luiza Cristina Godim DominguesREYES, FélixCAMARGO, João Lauro Viana deRODRIGUES, Maria Aparecida Marchesan2024-04-08T11:24:48Zoai:ojs.periodicos.puc-campinas.edu.br:article/9098Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2024-04-08T11:24:48Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false
