Orange is one of the primary fruits processed into juice and other products worldwide, leading to a vast amount waste accumulation. Such has been considered as an attractive candidate for upcycling obtain bioactive components remaining. The present study investigated extraction essential oil (EO), flavonoids, pectin from industrial orange with holistic approach. To maximize EO yield d-limonene concentration, hydrodistillation (HD) conditions were selected be 5.5 mL water/g solid 180 min. Remaining solids further used flavonoid where conventional solvent, sequential ultrasound + ultrasound-assisted (UE) applied. UE applied 50 min 120 solvent/g yielded highest total phenolic (TPCs) contents (TFCs), antioxidant capacity, hesperidin neohesperidin concentrations. In terms TPC, TFC, antibacterial activity, both fractions demonstrated moderate high bioactivity. At final step, ethanol precipitation was that solubilized in hot water during HD it characterized by Fourier transform infrared, degree esterification, galacturonic acid content. Practical application: ensure utilization food, pharmaceutical, cosmetic industries, this presents combined method several value-added compounds waste. Bioactive flavonoids obtained could have applications functional supplements, or formulations, whereas extracted can many formulated foods drugs.

The search for new forms to extend foodstuffs’ shelf-life through the use of natural compounds and extracts continues grow among researchers industry. In this line thought, main objective work was develop, characterize evaluate effectiveness an active food packaging based on polylactic acid (PLA) incorporated with obtained from grape and/or pomegranate by-products. vitro, antioxidant methods were applied capacity three extracts: wort extract, freeze-dried peels extract (PPE-FD), (PPE-N). Punicalagin (A + B) ellagic determined in PPE-FD, PPE-N, films by UHPLC-DAD. New PLA-based PPE-FD (PLA/3PPE) (PLA/3PP) developed, their chemical, mechanical, barrier properties evaluated. Moreover, film carried out study lipid oxidation state microbial contamination two high-fat content foodstuffs, almonds beef meat. presented high total phenolics flavonoid compounds. PLA/3PPE PLA/3PP prevented meat antimicrobial activity against Staphylococcus aureus. addition PLA did not affect morphology polymer. Although both punicalagin acid, only identified quantified PLA.

Dual Emerging Applications of Solid-State Fermentation (SSF) with Aspergillus niger and Ultrasonic-Assisted Extraction (UAE) for the Obtention of Antimicrobial Polyphenols from Pineapple Waste

Fermentation, Journal Year: 2023, Volume and Issue: 9(8), P. 706 - 706

Published: July 26, 2023

The exploration of natural antimicrobial compounds is necessary due to the current bacterial resistance synthetic antibiotics. For this reason, pineapple residues were evaluated as a source phenolic with capacity. Pineapple fermented A. niger GH1 and subjected ultrasound for extraction compounds. In solid-state fermentation (SSF), peel core (70:30) 32 h. Ultrasonic-assisted (UAE) was optimized. factors solid–liquid ratio (X1), ethanol concentration (X2), cycle (X3) optimized through Box–Behnken statistical design, using total phenol content (TPC) response variable. pre-purified extract amberlite characterized HPLC-MS we measured activity against Listeria monocytogenes, Staphylococcus aureus, Escherichia coli. optimal values X1, X2, X3 82 mg/mL, 26%, two cycles, respectively. effective an agent S. aureus L.

Advanced Extraction Techniques Combined with Natural Deep Eutectic Solvents for Extracting Phenolic Compounds from Pomegranate (Punica granatum L.) Peels

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(18), P. 9992 - 9992

Published: Sept. 17, 2024

Pomegranate (Punica granatum L.) peel is a potential source of bioactive phenolic compounds such as ellagic acid and α- β-punicalagin. This work explores the efficiency natural deep eutectic solvents combined with ultrasound-assisted extraction (UAE) pressurized liquid (PLE) for their extraction. Five NaDESs were evaluated by employing UAE (25 °C, 50 min) to determine total content (Folin–Ciocalteu assay) β-punicalagin contents (high-performance chromatography (HPLC-DAD)). The NaDES composed choline chloride (ChCl) glycerol (Gly) (1:2, molar ratio) was most efficient in when compared rest water extracts. Therefore, ChCl:Gly further using PLE at different temperatures (40, 80, 120 160 °C). PLE-NaDES extract obtained 80 °C 20 min 1500 psi exhibited highest PLE-water extracts under same conditions. Combining or emerges sustainable alternative extracting from pomegranate peel.

Food waste presents a critical environmental and economic challenge across Europe. In the Mediterranean region, agricultural industry generates considerable quantities of citrus fruits, leading to significant byproduct waste, which remains underutilized. To help address this, this study explored valorization orange peel using non-thermal ultrasonic-assisted extraction (UAE) one-factor-at-a-time experimental design investigate effects nine chemical physical UAE parameters. The goal was identify ideal operational ranges for each parameter several responses (bioactive compound recovery, antioxidant activity, radical scavenging activity), thus elucidating most influential factors their role in co-extracting various classes natural compounds. key findings revealed that polarity ionic potential medium, tuned through ethanol:water or pH, significantly influenced both profile bioactivity extracts. Notably, citric acid citrates appeared stabilize co-extracted Lower solid-to-liquid ratios increased yields, while particle sizes between 1400 710 µm enhanced phenolic recovery by approximately 150 mg/L GAE. contrast, increases pulse, probe diameter, immersion depth, time led degradation bioactive compounds, whereas maximal amplitude improved up 2-fold. Collectively, these insights provide foundation optimizing valorize waste.
