Conventional, non-conventional extraction techniques and new strategies for the recovery of bioactive compounds from plant material for human nutriti…
2019
Considering a large number of variations in the chemical structures of bioactive compounds (BACs) that are valuable to humans and a large number of their sources, it is necessary to build a standard and integrated extraction and analytical approaches for obtaining these compounds. From this perspective, the main purpose of this Special Issue of Food Research International was to publish research related to the extractions with data about isolation of BACs from plant matrices for human nutrition. This Special Issue includes both, conventional and innovative extraction techniques, highlighting their characteristics and advantages in relation to the target matrix. Many of presented works conta…
Extraction of Phenolic Compounds from Fresh Apple Pomace by Different Non-Conventional Techniques
2021
Red Delicious apple pomace was produced at laboratory scale with a domestic blender and different non-conventional extraction techniques were performed to isolate phenolic compounds, such as ultrasound-assisted extraction (UAE), ultraturrax extraction (UTE), accelerated solvent extraction (ASE) and pulsed electric field (PEF) extraction pre-treatment. Total phenolic content (TPC) was determined by Folin–Ciocalteu assay. Phloridzin, the main phenolic compound in apples, was determined by chromatographic analysis Q-TOF-LC/MS. The results obtained with these techniques were compared in order to identify the most efficient method to recover polyphenols. The highest value of TPC (1062.92 ± 59.80…
Estudio de perfilación de metabolitos secundarios de extractos vegetales obtenidos mediante técnicas y estrategias no convencionales para el desarrol…
2022
En esta tesis doctoral se desarrolló en el entorno de la economía verde y el reciclaje de residuos alimentarios estudiando diferentes técnicas de extracción no convencionales. En primer lugar, se aislaron polifenoles de matrices complejas producto del desperdicio de alimentos, como son las hojas de Moringa oleifera, mediante extracción asistida por ultrasonidos (UAE). El enfoque de diseño experimental permitió optimizar las mejores condiciones de extracción (MeOH:H2O 50:50, v/v, proporcion 1:60 Sólido/Líquido (S/L), 60°C, 60 min) para obtener un contenido fenólico total (TPC) de 13,4 mg expresados como equivalentes de ácido gálico (GAE)/g de materia seca. Por lo tanto, la caracterización y …
