Polyphenols in food processing wastewaters: A review on their identification and recovery

Cleaner and Circular Bioeconomy, Journal Year: 2023, Volume and Issue: 5, P. 100048 - 100048

Published: May 9, 2023

Polyphenols are strong natural antioxidants, associated with anti-inflammatory, disease prevention and anti-microbial effects. Due to their water solubility, these molecules at least partially transferred process waters during processing of foods crops which contain them. As wastewater components, polyphenols can impart toxicity impact microbial treatment. Their recovery contribute not only treatment reuse, but also reducing economic nutritional losses. Although olive mill has been the most thoroughly studied effluent for polyphenol recovery, other wastewaters deserve attention. This paper reviews containing generating processes, reports on identified quantities, as well methods. It sheds light state art existing research gaps highlights need pilot industrial scale studies, evaluation proposed technologies, ultimately providing support enhancement circular economy in food industry.

Anthropometric and cardiometabolic effects of polyphenols in people with overweight and obesity: an umbrella review

Nutrition Reviews, Journal Year: 2024, Volume and Issue: 82(11), P. 1556 - 1593

Published: Jan. 12, 2024

Abstract Context Polyphenols are plant-based compounds with potential anti-inflammatory, antioxidant, and anti-obesogenic properties. However, their effects on health outcomes remain unclear. Objective To evaluate the of polyphenols anthropometric cardiometabolic markers. Data Sources Six electronic databases—namely, EMBASE, CINAHL, PubMed, Scopus, The Cochrane Library (reviews only), Web Science—were searched for relevant systematic reviews meta-analyses (SRMAs). Extraction Three reviewers performed data extraction via a data-extraction Microsoft Excel spreadsheet. Analysis An umbrella review meta-analysis existing SRMAs was conducted. Eighteen published from 2015 to 2023, representing 445 primary studies 838 unique effect sizes, were identified. Meta-analyses conducted using random-effects models general inverse variance. Polyphenol-containing foods found significantly improve weight (-0.36 kg; 95% confidence interval [CI]: −0.62, 0.77 P < 0.01, I2 = 64.9%), body mass index (−0.25 kg/m2; CI: −0.34, −0.17 0.001, 82.4%), waist circumference (−0.74 cm; −1.34, −0.15 99.3%), low-density-lipoprotein cholesterol (−1.75 mg/dL; −2.56, −0.94; 98.6%), total (−1.23 −2.00, −0.46; 0.002, 94.6%), systolic blood pressure (−1.77 mmHg; −1.77, −0.93 72.4%), diastolic (−1.45 −2.09, −0.80 61.0%), fat percentage (−0.70%; −1.03, −0.36%; 52.6%), fasting glucose (−0.18 −0.35, −0.01 0.04, 62.0%), C-reactive protein (CRP; including high-sensitivity-CRP [hs-CRP]) (−0.2972 −0.52, −0.08 87.9%). No significant changes high-density-lipoprotein (−0.12 −1.44, 0.69; 0.67, 89.4%) triglycerides (−1.29 −2.74, 0.16; 0.08, 85.4%). Between-study heterogeneity could be explained by polyphenol subclass differences. Conclusion findings this support beneficial metabolic markers, but discretion is warranted determine clinical significance magnitude biomarker improvements.

Gestational Diabetes and the Gut Microbiota: Fibre and Polyphenol Supplementation as a Therapeutic Strategy

Microorganisms, Journal Year: 2024, Volume and Issue: 12(4), P. 633 - 633

Published: March 22, 2024

Gestational diabetes mellitus (GDM) is an escalating public health concern due to its association with short- and long-term adverse maternal child outcomes. Dysbiosis of microbiota within the gastrointestinal tract has been linked development GDM. Modification dysbiosis through dietary adjustments attracted considerable attention as adjunct strategies improve metabolic disease. Diets high in fibre polyphenol content are associated increased gut alpha diversity, reduced inflammation oxidative processes improved intestinal barrier function. This review explores potential supplementation prevent GDM by investigating their impact on composition

Natural Polyphenols and the Corrosion Protection of Steel: Recent Advances and Future Perspectives for Green and Promising Strategies

Metals, Journal Year: 2023, Volume and Issue: 13(6), P. 1070 - 1070

Published: June 3, 2023

Corrosion is recognized as an unavoidable phenomenon and steel, particularly carbon strongly susceptible to corrosion. damages cause serious material, energy, economic losses well negative impacts on the environment. As a result, research interest has been focused development of effective corrosion prevention strategies. However, some most commonly used inhibitors, such chromates pyridines, are harmful human environmental health. Polyphenols natural, non-toxic, biodegradable compounds from plant sources or agricultural by-products. Polyphenols’ chelating capacity acknowledged since 1990s, tannins, in particular, have widely exploited green rust converters phosphoric acid-based formulations recover rusty steel. Polyphenolic recently investigated method prevention. This review overviews not only polyphenolic converters, but also application anticorrosive coatings containing polyphenols. Moreover, polyphenols were discussed active component corrosion-inhibiting primers promote strong adhesion between steel surface topcoat layer. Finally, overview use additives sustainable systems improve resistance provided.
