Biorefining of the Prosopis juliflora fruit for ethanol production. Evaluation of the conditioning and pretreatment stages

The fruits of Prosopis juliflora have the potential to be raw material in the production of bioethanol due to its high carbohydrate and fiber content, and its high productivity in arid localities. P. juliflora fruits were characterized chemically, its sun drying kinetics was modeled and 2 physicoche...

P. juliflora fruits were characterized chemically, its sun drying kinetics was modeled and 2 physicochemical pretreatments were evaluated. The fruits showed a moisture content of 12.51% on a wet basis (wb), 14.84% protein, 2.27% fat, 20.15% fiber, 58.49% Nitrogen Free Extract (NFE) and 4.25% of ash, on dry basis (db). The prediction sun drying of Faneite-Suárez model was the best, within the range of prevailing weather conditions. The acid pretreatment (6% of sulfuric acid, for 20 min, at 121 ° C) got the highest content of reducing sugars, 37.85%. The evaluated fruits can be used in the production of bioethanol through a technically feasible and sustainable processing route. Los frutos del Prosopis juliflora, tienen el potencial de ser materia prima en la producción de bioeta­nol debido a su elevado contenido de carbohidratos y fibra, y su alta productividad en localidades áridas. Frutos de P. juliflora fueron caracterizados químicamente, fue modelada su cinética de secado al sol y fueron evaluados 2 pretratamientos fisicoquímicos. Las frutos resultaron tener 12,51% de Humedad en base húmeda (bh), 14,84% de proteínas, 2,27% de grasa, 20,15% de fibra, 58,49% de Extracto libre de nitrógeno (ELN) y 4,25% de ceniza, en base seca (bs). El modelo Faneite-Suárez es el que mejor predice el secado al sol, dentro del rango de condiciones meteorológicas imperan­tes. El pretratamiento ácido (6% de ácido sulfúrico, por 20 min, a 121oC) fue con el que se obtuvo el mayor contenido de azúcares reductores, un 37,85%. Los frutos evaluados pueden ser usados en la producción de bio-etanol mediante una ruta de procesamiento técnicamente factible y sostenible. 2017-12-15 2019-03-19T16:22:50Z 2019-03-19T16:22:50Z http://purl.org/coar/resource_type/c_6501 http://purl.org/coar/version/c_970fb48d4fbd8a85 https://revistas.unilibre.edu.co/index.php/avances/article/view/1295 10.18041/1794-4953/avances.1.1295 http://hdl.handle.net/10901/15110 spa https://revistas.unilibre.edu.co/index.php/avances/article/view/1295/1002 Revistas – Ingenierías Derechos de autor 2017 Las opiniones de los autores son de su exclusiva responsabilidad https://creativecommons.org/licenses/by-nc-nd/4.0/ http://creativecommons.org/licenses/by-nc-nd/2.5/co/ Atribución-NoComercial-SinDerivadas 2.5 Colombia application/pdf Universidad Libre AVANCES: Investigación en Ingeniería; Vol. 14 Núm. 1 (2017): Avances Investigación en Ingeniería; 169-183 2619-6581 1794-4953 10.18041/avances.v14i1
