Tannins extraction: A key point for their valorization and cleaner production

Abstract: Tannins are phenolic compounds with considerable abundance in nature. They have attracted significant attention lately owing to their huge variety of potential applications. Accordingly, the tannin-related activity in terms of research has undergone a great boost, especially as green feedstock for materials in several fields. Nevertheless, the extraction process remains as the main bottleneck for their valorization, due to their heterogeneous nature. In the present review, a comprehensive study of the main typ… Show more

“…In the form of polymeric flavonoids, they have limited to no solubility in water, whereas in oligomeric form, they are water soluble. Within the flavonoids group, condensed tannins are considered as flavanols, since they are composed of flavan‐3‐ol moieties (de Hoyos‐Martínez, Merle, Labidi, & Charrier–El Bouhtoury, ). In this study, total condensed tannin content of Teucrium polium extract was obtained 3.77 mg/g.…”

“…Conventional methods involve maceration and infusion, but new methods such as microwave‐assisted extraction, pressurized liquid extraction, and ultrasound‐assisted extraction can bring important advantages such as shorter reaction times and lower quantities of chemicals. A review of extraction methods, major strengths, and weaknesses was recently published …”

“…The procedures should be optimized in a case-by-case approach, depending on the source, the extraction method and the required nature of the extractible compounds (polyphenols, condensed or hydrolysable tannins). [13] Extraction yields generally increase with the polarity of solvents [5] and extractions in ethanol, [11] methanol, [13] and aqueous solution [11] have been successful. Conventional methods involve maceration and infusion, but new methods such as microwave-assisted Sílvia Santos completed the Ph.D. in Chemical and Biological Engineering in 2009, at the Faculty of Engineering of the University of Porto (FEUP), with a thesis supervised by Dr. Rui Boaventura.…”
