The recycling and revalorization of wastes from the agri-food industry (AFI) have emerged in scientific scenario as a multidisciplinary working field framework circular bioeconomy. Residues side materials AFI result great source raw products with increasing social economic impact. In this regard, phenolic compounds are possibly most relevant group phytochemicals because their multiple healthy properties, including antioxidant, anti-inflammatory, hypolipidemic, antibacterial activities. Among other sources, olive oil, winemaking, fruit vegetable juice been considered to assess revalorization. paper reviews recovery characterization waste extracts generate by-products rich polyphenols for chemical, nutraceutical, food science applications. Polyphenols recovered by solvent extraction conventional advanced techniques. resulting complex, major should be identified quantified. profiling analytes such proanthocyanins, curcuminoids, resveratrol derivatives, caffeic acids, oleuropein is often performed liquid chromatography UV/Vis or fluorescence detection. Additionally, coupled mass spectrometry technique choice unambiguous identification target structural elucidation new unknown molecules. Complementarily, antioxidant activity can determined using spectrophotometric assays.

Plant extracts and essential oils have a wide variety of molecules with potential application in different fields such as medicine, the food industry, cosmetics. Furthermore, these plant derivatives are widely interested human animal health, including potent antitumor, antifungal, anti-inflammatory, bactericidal activity. Given this diversity, methodologies were needed to optimize extraction, purification, characterization each class biomolecules. In addition, products can still be used synthesis nanomaterials reduce undesirable effects conventional routes based on hazardous/toxic chemical reagents associate properties those present oils. Vegetable chemically complex, although they already nanomaterials, limited studies examined which effectively acting stabilization nanostructures. Similarly, few investigated whether coating derived from would bring benefits or somehow their This synergistic effect presents promising field further explored. Thus, review article, we conducted comprehensive addressing main groups oils, extraction capacity, available for characterization. Moreover, highlighted metallic antimicrobial capacity. correlated extract’s role activity, considering synergy between product forms associated nanomaterials.

Phenolic compounds (PCs) are widespread secondary metabolites with potent biological activity. Their sources mainly plants from cultivated and natural states, providing valuable protective health-promoting extracts. The wide activity of PCs (antioxidant, anti-inflammatory, antimicrobial, antiatherosclerotic, antidiabetic, antiallergic, prebiotic, antimutagenic) means that new constantly being sought, as exemplified by extracting these tissue culture or agricultural by-products. Plant phenols show marked qualitative quantitative variation not only at different genetic levels (between within species clones) but also between physiological developmental stages. Assessing seasonal variations in phenolic content allows for selecting the best time to harvest plant. Learning about causes PCs' variability putting this knowledge into practice can significantly increase yields extract most compounds. properties resulting consuming products rich plant undeniable, so it is worth promoting high-phenolic a regular diet. This paper presents an overview use potential therapeutic alternatives. Additionally, factors complex genome ontogeny levels, relevant practical terms basis further scientific research, presented.

Each year, 20 million tons of wine by-products are generated, corresponding to 30% the total quantity vinified grapes. Wine a source healthy bioactive molecules, such as polyphenols and other molecules (pigments, fibers, minerals, etc.). The abundance compounds assures promising future for nutritional foodstuff production. can be used fortify aromatized waters infusions, bread, pasta, dairy products, alcohol, sugary beverages, processed foods. These innovative products part Mediterranean diet great interest both human environmental health. Pre-clinical studies show that consumption food produced with or their extracts attenuates inflammatory state increases antioxidant status. As such, provide protective effects against underlying pathophysiological hallmarks some chronic diseases atherosclerosis, diabetes, hypertension, obesity, cancer. However, poor bioavailability warrants further investigation on how optimize efficacy by-products, more clinical trials also needed. scientific evidence has validated uses dietary nature helped promote use functional prevent diseases.

Agrifood industries generate large amounts of waste that may result in remarkable environmental problems, such as soil and water contamination. Therefore, proper management treatment have become an environmental, economic, social challenge. Most these wastes are exceptionally rich bioactive compounds (e.g., polyphenols) with potential applications the food, cosmetic, pharmaceutical industries. Indeed, recovery polyphenols from agrifood is example circular bioeconomy, which contributes to valorization while providing solutions problems. In this context, unconventional extraction techniques at industrial scale, microwave-assisted (MAE), has demonstrated its efficacy laboratory level for analytical purposes, been suggested search more efficient procedures. On other hand, natural deep eutectic solvents (NADES) proposed green alternative typical solvents. This review aims provide comprehensive insights regarding phenolic waste. Specifically, it focuses on utilization MAE conjunction NADES. Moreover, delves into possibilities recycling reusing NADES a sustainable cost-efficient application. The results obtained MAE-NADES approach show high efficiency contributing practices field product extraction. However, further research necessary improve our understanding strategies, optimize yields, reduce overall costs, facilitate scaling-up.

Around two million tons of olive oil are produced in Europe annually, with Portugal being among the top five European oil-producing countries. Olive production results a substantial amount waste form leaves. These discarded leaves contain valuable phenolic compounds antioxidant, anti-inflammatory, hypoglycaemic, neuroprotective, and antiproliferative properties. Due to their richness polyphenols health-promoting properties, can be considered potential functional food ingredient. Thus, sustainable practices for reusing leaf demand. In this study, polyphenolic content from different Portuguese locations was determined using HPLC-UV-Vis after defining best fit-for-purpose liquid extraction strategy. The differences vitro antioxidant activity these samples were by several methodologies based on radical scavenging (against 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), 2,2-diphenyl-2-picrylhydrazyl (DPPH), peroxyl (ORAC)) reducing properties (cupric-reducing capacity (CUPRAC), Folin-Ciocalteu assay (FC)), unveil relationship between profile quantity mechanisms capacity. At last, stability extracted upon lyophilization exposition surrogate biological fluids assessed, envisioning future incorporation products.

Winery wastes are rich in polyphenols with high added value to be used cosmetics, pharmaceuticals, and food products. This work aims at recovering purifying the polyphenolic fraction occurring malolactic fermentation lees generated during production of Albariño wines. Phenolic acids, flavonoids, related compounds were recovered from this oenological waste by green liquid extraction using water as solvent. The resulting extract solution was microfiltered remove microparticles further treated ultrafiltration (UF) membranes 30 kDa 5 molecular weight cut-offs (MWCOs). feed sample filtrate retentate solutions each membrane system analyzed reversed-phase chromatography (HPLC) UV mass spectrometric (MS) detection. most abundant extracts identified quantified, namely: caftaric acid a concentration 200 µg g-1 trans-coutaric acid, cis-coutaric gallic astilbin concentrations between 15 40 g-1. Other minor phenolic acids flavanols also found. UF process did not modify composition, but filtration through poly-acrylonitrile elicited decrease content. Hence, recommended pre-process extracts. combined purification presented here is environmentally friendly demonstrates that wines valuable source compounds, especially acids.
