Conteúdo: | In this study, the cold-pressing extraction conditions of regular and defective green coffee beans were compared to obtain green coffee oil (GCO). The total phenolic content (TPC) in GCO, press-cake, and sediment was quantified. GCO was charac-terized by mass spectrometry and incorporated into carboxymethyl cellulose (CMC) films. Highest TPC was found for cake and sediment from defective beans (55.8 and 41.1 mg of GAE/g dry matter, respectively). Oil yield was increased (5.9%) using the finest particle size (<850 ?m). Fatty acids, phenolic compounds, and carboxyatrac-tyloside II were identified in GCO by Direct-Infusion Electrospray Ionization-Mass Spectrometry. Films added with 0.3 ml of GCO and lecithin (0.1 g/1.5 g CMC) exhib-ited greater strength (38.6 MPa) and flexibility (27.6%). Results are promising for both the production of CMC-GCO films, and high-value antioxidant from GCO and its by-products with a sustainable perspective using defective Arabica beans.
