Recovery of Polyphenols from Agri-Food By-Products: The Olive Oil and Winery Industries Cases

Foods, Journal Year: 2022, Volume and Issue: 11(3), P. 362 - 362

Published: Jan. 26, 2022

The production of olive oil and wine are two the main agri-food economic activities in Southern Europe. They generate large amounts solid liquid wastes (e.g., pomace, mill wastewater, grape stems, lees, processing wastewater) that represent a major environmental problem. Consequently, management these residues has become big challenge for industries, since they harmful to environment but rich bioactive compounds, such as polyphenols. In recent years, recovery phenolic compounds been proposed smart strategy valorization by-products, from circular economy perspective. This review aims provide comprehensive description state art techniques available analysis, extraction, purification polyphenols winery residues. Thus, integration implementation could sustainable solution sectors.

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.

Antimicrobial Activities of Natural Bioactive Polyphenols

Pharmaceutics, Journal Year: 2024, Volume and Issue: 16(6), P. 718 - 718

Published: May 27, 2024

Secondary metabolites, polyphenols, are widespread in the entire kingdom of plants. They contain one or more hydroxyl groups that have a variety biological functions natural environment. These uses include polyphenols food, beauty products, dietary supplements, and medicinal products grown rapidly during past 20 years. Antimicrobial described together with their sources, classes, subclasses. Polyphenols found different such as dark chocolate, olive oil, red wine, almonds, cashews, walnuts, berries, green tea, apples, artichokes, mushrooms, etc. Examples benefits antiallergic, antioxidant, anticancer agents, anti-inflammatory, antihypertensive, antimicrobe properties. From these classes helpful for growth internal functional systems human body, providing healthy fats, vitamins, minerals, lowering risk cardiovascular diseases, improving brain health, rebooting our cellular microbiome health by mitochondrial uncoupling. Among various (curcumin, naringenin, quercetin, catechin, etc.) primarily antimicrobial activities discussed along possible future applications.

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.
