Resumo: | Araucaria (Araucaria angustifolia) is a tree species found in the Southeast and South of Brazil. It is also known as Brazilian pine, presenting fruits of high acceptance. However, its processing generates by-products that are little used. Thus, this work aimed to extract and characterize the cellulose obtained from the pinion husk, as well as to evaluate the contents of ash, lignin, cellulose and α-cellulose in its composition. The raw material and the extracted cellulose were characterized by X-ray fluorescence analysis (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). As for the contents of chemical composition detected, the husks showed 1.6% ash, 7% extractives, 34% lignin and 55% cellulose, being 46% α-cellulose and 9% hemicellulose. It was observed by XRD that the removal of amorphous materials resulted in a gain of crystallinity (from 19 to 33%). Proving the efficiency of the extraction, the characterization of the cellulose obtained was shown to be of high purity, since the main band of the lignin (FTIR) and the amorphous materials of the cellulosic sample (TGA) disappeared. Finally, this work shows that the pinion bark is a rich source of cellulose, making it possible to obtain nanocrystals. |

También se le conoce como pino brasileño, presentando frutos de alta aceptación. Sin embargo, su procesamiento genera subproductos poco utilizados. Así, este trabajo tuvo como objetivo extraer y caracterizar la celulosa obtenida de la cáscara del piñón, así como evaluar los contenidos de ceniza, lignina, celulosa y α-celulosa en su composición. La materia prima y la celulosa extraída se caracterizaron mediante análisis de fluorescencia de rayos X (XRF), difracción de rayos X (XRD), espectroscopia infrarroja por transformada de Fourier (FTIR) y análisis termogravimétrico (TGA). En cuanto a los contenidos de composición química detectados, las cáscaras presentaron 1,6% de ceniza, 7% de extractos, 34% de lignina y 55% de celulosa, siendo 46% de α-celulosa y 9% de hemicelulosa. Se observó mediante XRD que la eliminación de materiales amorfos dio como resultado una ganancia de cristalinidad (del 19 al 33%). Comprobando la eficiencia de la extracción, la caracterización de la celulosa obtenida se mostró de alta pureza, ya que desaparecieron la banda principal de la lignina (FTIR) y los materiales amorfos de la muestra celulósica (TGA). Finalmente, este trabajo demuestra que la corteza del piñón es una rica fuente de celulosa, lo que permite la obtención de nanocristales.Araucária (Araucaria angustifolia) é uma espécie arbórea encontrada nas regiões Sudeste e Sul do Brasil. É também conhecido como pinho brasileiro, apresentando frutos de alta aceitação. Porém, seu processamento gera subprodutos que são pouco utilizados. Assim, este trabalho teve como objetivo extrair e caracterizar a celulose obtida da casca do pinhão, bem como avaliar os teores de cinzas, lignina, celulose e α-celulose em sua composição. A matéria-prima e a celulose extraída foram caracterizadas por análise de fluorescência de raios X (XRF), difração de raios X (XRD), espectroscopia de infravermelho por transformada de Fourier (FTIR) e análise termogravimétrica (TGA). Quanto aos teores de composição química detectados, as cascas apresentaram 1,6% de cinzas, 7% de extrativos, 34% de lignina e 55% de celulose, sendo 46% de α-celulose e 9% de hemicelulose. Foi observado pelo XRD que a remoção dos materiais amorfos resultou em ganho de cristalinidade (de 19 a 33%). Comprovando a eficiência da extração, a caracterização da celulose obtida mostrou-se de alta pureza, uma vez que a banda principal da lignina (FTIR) e os materiais amorfos da amostra celulósica (TGA) desapareceram.
