- Characterization of pineapple peel (Ananas comosus) Perolera variety as a potential resource for bioethanol production Maria Victoria Celis Cabeza Carlos Daniel Toro Ruedas Dora Cecilia Rodríguez Ordoñez John Wilmer Parra Llanos Ingeniería Lignin Biofuel Holocellulose Organic waste Reducing sugars Pineapple production in Colombia generates around 185,000 tons of waste per year, consisting of peels, residual pulp, stems and leaves. Due to its lignocellulosic nature, pineapple peel shows significant potential to produce bioethanol, leading to the use of this waste. The objective of this research was to characterize the peels of pineapple (Ananas comosus) of the Perolera variety, grown in the municipality of Teorama, Catatumbo Region (Norte de Santander), to evaluate its potential for the production of bioethanol. The physical-chemical characterization of the lignocellulosic material was carried out, assessing the percentage of moisture, ash, ethanol-hexane extractables, holocellulose, cellulose, hemicellulose, and lignin soluble and insoluble in acid, each analysis was carried out in triplicate. The most relevant results obtained in the characterization were: 83.51 % moisture, holocellulose, which is made up of cellulose and hemicellulose, with percentages on a dry basis of 54.90 and 45.09 %, respectively, which indicates that a higher cellulose content means a greater amount of glucose, which facilitates the production of reducing sugars through hydrolysis processes. On the other hand, the total lignin content was 26.40 %, which contributes to structural support in the cell wall of pineapple peels, giving it rigidity and permeability. The high lignin content can make the conversion of cellulose into simple sugars difficult, which is why it is suggested to carry out a delignification process so that the cellulose is more susceptible to enzymatic hydrolysis, thus optimizing bioethanol production. 2024 artículo científico 0120-100X https://www.redalyc.org/articulo.oa?id=342082796006 https://www.redalyc.org/journal/3420/342082796006/ https://www.redalyc.org/journal/3420/342082796006/html/ https://www.redalyc.org/journal/3420/342082796006/342082796006.epub https://www.redalyc.org/journal/3420/342082796006/movil 10.18273/revion.v37n3-2024006 en http://www.redalyc.org/revista.oa?id=3420 Revista ION application/pdf Universidad Industrial de Santander Revista ION (Colombia) Num.3 Vol.37
