dc.description.abstractLa panela es producida en 30 países, Colombia es el segundo país productor de panela después de la india. En el proceso de producción de panela se genera biomasa residual en la molienda para la extracción de los jugos de caña de azúcar, que generan problemas a los productores quienes lo utilizan como combustible para el calentamiento de las hornillas en el proceso de producción, generando gases tóxicos (CO2). El bagazo en su pared celular contiene celulosa, uno de los polímeros más abundantes de la naturaleza, ofreciendo alternativas en las industrias de alimentos y conservación del medio ambiente. Otro inconveniente para los productores de panela es en el proceso de clarificación, se utilizan mucílagos vegetales propios de cada región como el balso, guácimo y caldillo los cuales se ha visto afectado en por su uso indiscriminado lo que ha llevado a subir su costo y utilizar floculantes alternativos. Se plantea una un floculante catiónico a partir de biomasa residual de bagazo de caña de azúcar, realizando una extracción de celulosa de la biomasa y realizando una modificación química selectiva de la celulosa dialdehído catiónica (CDAC), y comparando la floculación del floculante catiónico con el balso traído del trapiche Buena Vista en el municipio de Santana Boyacá. Se caracterizó la celulosa y CDAC por técnicas como Espectroscopia infrarroja con transformada de Fourier (FT-IR), Raman, Difracción de rayos-X (DRX), se realizó un estudio a las propiedades térmicas por termogravimetría (TGA) y calorimetría diferencial de barrido (DSC) corroborando la extracción exitosa de celulosa con un rendimiento del 50% y la modificación a CDAC, la capacidad clarificante del floculante catiónico es eficiente comparado con el balso nativo de la región de Boyacá.spa

dc.description.abstractenglishPanela is produced in 30 countries; Colombia is the second producer of panela after India. In the panela production process, residual biomass is generated in the mill for the extraction of sugarcane juices, which generate problems for the producers who use it as fuel for the heating of the burners in the production process, generating gas toxic (CO2). The bagasse in its cell wall contains cellulose, one of the most abundant polymers in nature, offering alternatives in the food and environmental conservation industries. Another disadvantage for panela producers is in the process of clarification, vegetable mucilages from each region are used, such as balsa, guácimo and caldillo, which has been affected by its indiscriminate use, which has led to an increase in its cost and use alternative flocculants. A cationic flocculant is proposed from residual biomass of sugarcane bagasse, performing a cellulose extraction of the biomass and carrying out a selective chemical modification of the cationic dialdehyde cellulose (CDAC), and comparing the flocculation of the cationic flocculant with the balsa brought from the trapiche Buena Vista in the municipality of Santana Boyacá. Cellulose and CDAC were characterized by techniques such as infrared spectroscopy with Fourier transform (FT-IR), Raman, X-ray diffraction (XRD), a thermal properties study by thermogravimetry (TGA) and differential scanning calorimetry. (DSC) corroborating the successful extraction of cellulose with a yield of 50% and the modification to CDAC, the clarifying capacity of the cationic flocculant is efficient compared to the native balsa of the Boyacá region.spa
