| Summary: | The valorization of byproducts such as defatted meal (DM) is essential for the implementation of a biorefinery structure and can be achieved through the application of emerging technologies, such as pressurized liquid extraction. This work aimed to apply pressurized liquid extraction to obtain products derived from the DM of crambe (<i>Crambe abyssinica</i> Hochst) seeds. The experiments investigated the effect of ethanol percentage in the hydroalcoholic solvent (25%, 50% and 75%, <i>v</i>/<i>v</i>) on the mass extract yield (MEY) and on the composition of the products obtained: phytochemical extract (PE) and processed flour (PF). The PE obtained using 25% ethanolic solvent had the highest MEY (23.48 wt%) and phenolic compounds, composed of caffeic, gallic and ferulic acids, which conferred activity against the fungus <i>C. albicans</i>. The solvents tested did not influence the content of soluble proteins. The solvent with 75% ethanol promoted the highest levels of glucosinolates (258.94 μmol/g) and tannins (8.80 mg/g) in the PE, reducing 96% and 98% of these contents in the PF produced. The PF obtained in the extraction with 75% ethanol contained phenolic compounds (~23 mg/100 g), dietary fibers (54.25 g/100 g) and soluble proteins (26.39 wt%), mainly composed of glutelin fraction. The PF also presented adequate functional properties, such as water solubility and absorption, which suggest potential use in pet food formulations. |
