Pressed palm fiber (PPF), a residue obtained from palm oil industry, is a source of bioactive compounds, such as carotenoids, which are used as food additives. It also has cellulose and hemicellulose that can be used to yield fermentable sugars for the production of second generation ethanol. Supercritical fluid extraction (SFE) of pressed palm fiber provides an oil rich in carotenoids while subcritical water hydrolysis (SubWH) produces hydrolysates with high amounts of fermentable sugars. In this work, the effects of pressure (15-30 MPa) and temperature (318 and 328 K) on SFE of carotenoids were investigated. The SFE extract with highest carotenoid content was obtained at 318 K and 15 MPa (2.3% d.b., 0.81 mg β-carotene/g extract). After the extraction, the influence of process temperature (423-633 K), pressure (15 and 25 MPa), solvent:feed ratio (120 and 240), and residence time (1.25-5 min) on SubWH of the extraction residue was studied. At the temperature of 523 K, the highest total reducing sugar yield (11-23 g glucose/100 g carbohydrate) and the highest biomass conversion (40-97%) were obtained for any pressure and solvent:feed ratio. The highest selectivity for saccharide formation was found at 423 K (20-59 mol glucose/mol furfural equivalent). Optimal conditions for high saccharide formation and low sugar degradation product in subcritical hydrolysis were obtained at 523 K, 15 MPa, solvent:feed ratio of 120, residence time of 2.5 min with a total reducing sugar yield of 22.9 g glucose/100 g carbohydrate and a conversion of 84.9%.93 4248Gupta, R., Demirbas, A., (2010) Gasoline, Diesel and Ethanol Biofuels from Grasses and Plants, pp. 1-24. , Cambridge University Press New YorkFrança, L.F., Meireles, M.A.A., Extraction of oil from pressed palm oil (Elaes guineensis) fibers using supercritical CO2 (1997) Ciência e Tecnologia de Alimentos (Campinas), 17, pp. 384-388Garrote, G., Dominguez, H., Parajo, J.C., Hydrothermal processing of lignocellulosic materials (1999) Holz Als Roh-Und Werkstoff, 57, pp. 191-202Moreschi, S.R.M., Petenate, A.J., Meireles, M.A.A., Hydrolysis of ginger bagasse starch in subcritical water and carbon dioxide (2004) Journal of Agricultural and Food Chemistry, 52, pp. 1753-1758Carvalheiro, F., Duarte, L.C., Girio, F.M., Hemicellulose biorefineries: A review on biomass pretreatments (2008) Journal of Scientific & Industrial Research, 67, pp. 849-864Kruse, A., Vogel, H., (2010) Chemistry in Near- And Supercritical Water In: Green Solvents, , Wiley, John & Sons, Incorporated Weinheim, GermanySchacht, C., Zetzl, C., Brunner, G., From plant materials to ethanol by means of supercritical fluid technology (2008) Journal of Supercritical Fluids, 46, pp. 299-321Demirbas, A., Biomass resource facilities and biomass conversion processing for fuels and chemicals (2001) Energy Conversion and Management, 42, pp. 1357-1378Jacobsen, S.E., Wyman, C.E., Cellulose and hemicellulose hydrolysis models for application to current and novel pretreatment processes (2000) Applied Biochemistry and Biotechnology, 84-86, pp. 81-96Chiu, K.L., Cheng, Y.C., Chen, J.H., Chang, C.J., Yang, P.W., Supercritical fluids extraction of Ginkgo ginkgolides and flavonoids (2002) Journal of Supercritical Fluids, 24, pp. 77-87Brunner, G., Near critical and supercritical water.
