A biorefinery approach for the simultaneous obtention of essential oils, organi...
Gómez-Mejía, Esther; Dias, Maria Inês; Pereira, Carla; Pires, Tânia C.S.P.; Palá-Paúl, Jesús; Rosales-Conrado, Noelia; León-González, María EugeniaThis investigation evaluates the valorization of citrus peels (lemon, tangerine, and orange) to recover both on-polar and polar fractions simultaneously. Citrus essential oils, abundant in limonene (74.4–33.7 %), exhibited great antioxidant activity (IC50 = 2.002 mg/mL) and Campylobacter jejuni halo inhibition (2.9 cm), particularly in tangerine and orange essential oils. The aqueous extracts were rich in quini...
A green alternative approach to citrus peel bio-waste disposal: characterisatio...
Gómez-Mejía, Esther; Palá-Paúl, Jesús; Lobo Roiz, Custódio; Heleno, Sandrina A.; Calhelha, Ricardo C.; Dias, Maria Inês; Rosales-Conrado, NoeliaCurrently, there is a great interest in promoting circular economy perspectives for the recovery of value-added bioactive compounds, potentially exploitable as bioactive natural ingredients, from agri-food bioresidues that causes serious environmental problems. The citrus juice industry is a powerful manufacturing industry that generates huge amounts of waste, mainly peels [1-2]. Material & Methods: A hydrodist...
Valorisation of black mulberry and grape seeds: Chemical characterization and b...
Gómez-Mejía, Esther; Roriz, Custódio Lobo; Heleno, Sandrina A.; Calhelha, Ricardo C.; Dias, Maria Inês; Pinela, José; Rosales-Conrado, NoeliaGrape (Vitis vinifera L. var. Albariño) and mulberry (Morus nigra L.) seeds pomace were characterized in terms of tocopherols, organic acids, phenolic compounds and bioactive properties. Higher contents of tocopherols (28 ± 1 mg/100 g fw) were obtained in mulberry, whilst grape seeds were richer in organic acids (79 ± 4 mg/100 g fw). The phenolic analysis of hydroethanolic extracts characterised grape seeds by ...
Chemical characterization and bioactivity evaluation of black mulberry and grap...
Gómez-Mejía, Esther; Roriz, Custódio Lobo; Heleno, Sandrina A.; Calhelha, Ricardo C.; Dias, Maria Inês; Pinela, José; Rosales-Conrado, NoeliaCircular economy is increasingly seen as a crucial way to reduce food by- products and residues and obtain valuable raw materials. There is a growing demand for industrial products with clean labels and bio benefits, where natural bioactive compounds play an important role. Among these natural biomolecules, polyphenols stand out for their health benefits against diseases such as cancer or diabetes. Thus, the us...
