In this study, the recovery of polyphenols from olive oil mill and winery waste was investigated. The performance ultrasound assisted extraction (UAE), microwave (MAE), pressurized liquid (PLE) assessed using ethanol–water mixtures, which are compatible with food, nutraceutical, cosmetic applications. efficiency pomace lees samples evaluated in terms total polyphenol content (TPC), determined by high chromatography (HPLC) Folin–Ciocalteu assay. effect solvent composition, temperature, time...
Winery and olive mill industries generate large amounts of wastes causing important environmental problems. The main aim this work is the evaluation different membrane separation processes like microfiltration, ultrafiltration, nanofiltration, reverse osmosis for recovery polyphenols from winery in aqueous solutions. Membrane were tested separately a closed-loop system, by an integration concentration mode sequential design (open-loop). Feed flow rate was varied 1 to 10 mL min-1, permeate...
Waste management presents a significant challenge for agri-food industries, but also an opportunity to recover valuable bioactive compounds, particularly phenolics, aligning with circular economy principles. This study compares the efficacy of conventional solvents and natural deep eutectic (NADES) in extracting polyphenols from olive leaves using scalable techniques solid–liquid extraction (SLE) mechanical stirring microwave-assisted (MAE). Key factors affecting yield, including solvent...
Spinach and orange by-products are well recognized for their health benefits due to the presence of natural polyphenols with antioxidant activity. Therefore, demand produce functional products containing recovered from vegetables fruits has increased in last decade. This work aims use integrated membrane process recovery spinach wastes, implemented on a laboratory scale. The clarification (microfiltration ultrafiltration, i.e., MF UF), pre-concentration (nanofiltration, NF), concentration...
Phenolic compounds recovery by mechanical stirring extraction (MSE) was studied from orange and spinach wastes using water as a solvent. The statistical analysis showed that the highest total polyphenol content (TPC) yield obtained 15 min, 70 °C, 1:100 (w/v) solid/solvent ratio pH 4 for orange; 5 50 1:50 6 spinach. Under these conditions, TPC 1 mg gallic acid equivalent (GAE) g-1 fresh weight (fw) 0.8 GAE fw spinach, respectively. MSE substantially increased phenolic yields (1-fold 2-fold...
More sustainable waste management in the winery and olive oil industries has become a major challenge. Therefore, valorization to obtain value-added products (e.g., polyphenols) is an efficient alternative that contributes circular approaches environmental protection. In this work, integration scheme was purposed based on extraction membrane separation processes, such as nanofiltration (NF) reverse osmosis (RO), for recovery of polyphenols from mill wastes. Membrane processes were evaluated...
La enzima endo-(1,3)-B-glucanasa tiene una función fisiológica en los procesos morfogenéticos durante el desarrollo y diferenciación algunos hongos. Adicionalmente, esta ha sido implicada ataque de hongo la interacción fitopatógeno-planta. Por lo que fúngica, se utilizado como sitio-objetivo para búsqueda dirigida antifúngicos. Utilizando un aislamiento bio-dirigido compuestos bioactivos, aislaron dos ácidos fenólicos tallos <em>Turnera diffusa</em>, cuales inhiben actividad...
