Best Poster Presentations of Polyphenols Applications 2021

During the 14th World Congress on Polyphenol Applications which was held as an interactove online event from September 22 to September 24 2021, the participants voted for the Best Poster Presentations.

Best Poster Presentation Award #1

The first award for the Best Proster Presentation was discerned to Teresa Herrera, PhD in Food Science and Technology, for her presentation on the "Development of Sustainable and Healthy Yogurts with Extracts of Wild Fruits Rich in Polyphenols".

Ms. Herrera's scientific career is mainly engaged in research  respect to bioactive compounds, extraction and characterization in legumes and fruits and also in the development of novel dairy products. 

"Our study is based on development novel healthy dairy products elaborated with extracts obtained of wild fruits rich in polyphenols. First, we evaluated and characterization wild fruits extracts, and selected the more interesting ones. Then,  produce yogurts that incorporate these wild fruits extracts  with antioxidants of natural origin as ingredients. This way can be a successful strategy for novel product development and could be valuable potential sources of safe and inexpensive antioxidants of natural origin in yogurts."

Best Poster Presentation Award #2

Another award for the Best Poster Presentation was given to Paulina Tapia Quirós, from Universidad Politécnica de Cataluña (Spain). She presented a poster about "Total Polyphenol Content and Antioxidant Capacity of Agri-Food Wastes: Estimation by Spectrophotometric Assays and High-Performance Liquid Chromatography".

"This study is dedicated to the valorization of agri-food wastes. In particular, this work is focused on the determination of the total polyphenol content (TPC) and antioxidant capacity from residues of the olive oil and wine production through different analytical techniques. For that purpose, some spectrophotometric assays (e.g. Folin-Ciocalteu (FC), 2,-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonat (ABTS), ferric reducing antioxidant power (FRAP)), and high-performance liquid chromatography (HPLC-UV) technique were used. Overall, the recovery of polyphenols from these agri-food wastes could provide a sustainable solution to olive oil and winery sectors."

Beneficial Effects of Cornelian Cherry polyphenols on NO/ROS Balance in Obese Zucker Rats

Prof. Olga Pechanova from Slovak Academy of Sciences, Slovakia will give a presentation entitled Beneficial Effects of Cornelian Cherry polyphenols on NO/ROS Balance in Obese Zucker Rats.

Prof. Pechanova will highlight about Cornelian cherries (CCs) that belong to promising anti-obesity substances. They aimed to study effects of coenzyme Q10 (CoQ10) and two varieties of CCs (Koralovij Marka and Wilde Type) on lipid profile, ROS, and nitric oxide (NO) production in obese Zucker rats. CoQ10 did not affect plasma lipid profile and NOS activity either in the heart left ventricle or aorta. On the other hand, Wilde Type decreased cholesterol and LDL levels. Koralovij Marka and Wilde Type increased NOS activity in the aorta, while not affecting the activity in the heart left ventricle. Koralovij Marka increased eNOS expression and did not affect ROS production, while Wilde Type increased SOD and decreased NADPH oxidase without affecting eNOS expressions in both tissues. In conclusion, CCs showed better beneficial effects than CoQ10 in all parameters studied.

Secoiridoids from Gentiana Lutea: Interaction with Bitter Receptors in the Gastrointestinal Tract and Enteroendocrine Pharmacological Application

Prof. Luigi Milella, from Università della Basilicata, Italy, will join Polyphenols Applications 2021. Prof. Milella will give a talk about "Secoiridoids from Gentiana Lutea: Interaction with Bitter Receptors in the Gastrointestinal Tract and Enteroendocrine Pharmacological Application".

According to his research, gentian root is known since centuries as an herbal bitter root and it has been traditionally used for several pharmacological applications. Moreover, the bitter principles of gentian root are secoiridoid glycosides like amarogentin and gentiopicrin. Recent evidences showed that bitter-tasting compounds modulate bitter taste receptors not only on the tongue but also in different parts of the gastrointestinal tract. In fact, it has been recently demonstrated as enteroendocrine in gut villi have functional bitter taste receptors and once activated they lead to release of enteroendocrine cell hormones. This latter can influence the dietary intake and there might be possibilities for studying their pharmacological application for regulating hunger and satiety.

Health-Promoting Effects of Hop-Derived Polyphenols Involve Modulation of the Gut-Liver-Brain Axis

Prof. Jan Frederik Stevens, from Oregon State University, USA, will join Polyphenols Applications 2021 in September to give a talk about "Health-Promoting Effects of Hop-Derived Polyphenols Involve Modulation of the Gut-Liver-Brain Axis". 

The main idea that Prof. Stevens will discuss concerns the increasing fact that the antioxidant and anti-inflammation hypothesis for polyphenol activity offers an unsatisfactory explanation for the health-promoting effects of dietary polyphenols. He confirms that using preclinical models of metabolic syndrome combined with a multi-organ, multi-omics data generation approach, it has been found that oral treatment of mice with the hop-derived polyphenol, xanthohumol, decreases liver fat accumulation, improves glucose tolerance, and mitigates cognitive impairments via modulation of the gut microbiota, nuclear receptor signaling, and via targeting metabolism that alters bile acid composition and suppresses ceramide accumulation.

Non-Covalent Interactions of Polyphenols and Polysaccharides – Friend or Foe?

It is a great pleasure to announce that Dr. Fabian Weber, from the University of Bonn, Germany, will join the Polyphenols Applications 2021 Congress this September as a major speaker. Dr. Weber will give a talk about "Non-Covalent Interactions of Polyphenols and Polysaccharides – Friend or Foe?" where he will mainly discuss the importance of non-covalent interactions of polyphenols and polysaccharides and the balance between keeping and breaking them.

To fulfill their technological, sensorial, and nutritional functions, polyphenols must be released from the plant material. Consequently, one of the main goals during food processing is their extraction. This implies the breaking of non-covalent bonds between polyphenols and cell wall polysaccharides. But these interactions tend to be very firm and resistant to breakage, thereby causing a decrease in the actual amount of released polyphenols. The downside of this release is that polyphenols are confronted with detrimental conditions, causing a rapid loss and a corresponding reduction in the nutritional and sensorial quality of the food. Simultaneously, interactions of polyphenols with polysaccharides can have protective effects. There seems to exist a balance between the need to break these interactions in order to increase their yield and to maintain these interactions in order to increase stability. It is worth mentioning that they also have an influence on the concentration of dietary fiber. The directed degradation of cell wall material can also be a tool to increase the content in soluble dietary fiber and the recovery of cell wall material from side streams can yield food ingredients that are abundant in dietary fiber and antioxidant phenolics, but also exhibit intense and vibrant hues.

Impact of aronia juice-based food supplement on DNA integrity in humans

Dr. Elke Richling, University of Kaiserslautern, Germany will join the Polyphenols Applications 2021 Congress and give a presentation entitled "Impact of aronia juice-based food supplement on DNA integrity in humans".

Dr. Richling will present her recent eight-week intervention study, in which she and her team investigated the effects of aronia (Aronia melanocarpa) juice-based food supplement on background and total DNA strand breaks in whole blood and response to H₂O₂-induced DNA strand breaks in isolated peripheral blood lymphocytes. The results showed a significant decrease of background DNA strand breaks after four and eight weeks of supplement consumption, compared to the wash out period. H₂O₂-induced DNA strand breaks were clearly diminished in the test group after four and eight weeks in comparison to the control group. Taken together, the consumption of the aronia juice-based food supplement contributed to the maintenance of DNA integrity in healthy volunteers.

Early-life combinatorial polyphenol-based prevention of estrogen receptor-negative breast cancer

Prof. Trygve Tollefsbol, University of Alabama at Birmingham, USA will join the Polyphenols Applications 2021 Congress which will be held on September 22-24, 2021 and will give a presentation entitled "Early-life combinatorial polyphenol-based prevention of estrogen receptor-negative breast cancer".

Prof. Tollefsbol's main focus will be on how to minimize the risk of  estrogen receptor-negative breast cancer.In fact, therapeutic efforts to control estrogen receptor-negative breast cancer have been disappointing for decades and novel approaches to prevent this too often fatal disease are of high priority. Field-driving important new directions using polyphenols in combination with other pytochemicals are now essential. Prof. Tollefsbol and his team have developed efficacious and safe early-life synergistic dietary approaches based on epigenetic mechanisms to enhance prevention or to slow progression of estrogen receptor-negative breast cancer.

Polyphenols as universal coatings and as bioactive agents in porous materials like cements

Prof. Vincent Ball from Université de Strasbourg, France will give a talk as the major speaker for the Polyphenols Applications 2021 Congress which will be organized on September 22-24, 2021 on "Polyphenols as universal coatings and as bioactive agents in porous materials like cements".

Prof. Ball will explain how polyphenols like tannic acid, pyrogallol, gallic acid and others are able to form thin films on all kinds of solid-liquid interfaces, can be deposited in the form of particulates when complexed with metallic cations like Fe3+ and can also take part in layered architectures (the so-called layer-by-layer film). In all cases they provide electroactivity, antimicrobial and anti-oxidant properties to the deposited films. We will finally show that the same polyphenols may be incorporated in cements and plaster to modify their wettability and to improve their biological and mechanical properties.

Valorization of Food Waste : Polyphenols extraction using Innovative Technologies

Prof. Richard Maroun, Dean Faculty of sciences at Saint-Joseph University Beirut, Lebanon will join the Polyphenols Applications 2021 Congress which will be held on September 22-24, 2021.

Prof. Richard Maroun will give a presentation entitled "Valorization of Food Waste: Polyphenols extraction using Innovative Technologies".

Summary of the talk: Food by-products are considered as a cheap source of valuable components since existing technologies allow for the recovery of the target compounds and the recycling into the food chain as functional additives in different industrial products.

Food waste valorization practices have gained much attention lately as a means of sustainable management. These materials constitute an underexploited source for the recovery of natural compounds. One of the main molecules extracted and purified are polyphenols. Our work aims to purify these natural antioxidant molecules through innovative technologies in order to reintegrate them as valuable additives in several final products such as food additives, pharmaceuticals, nutraceuticals, cosmetics, etc.

Prof. Richard Maroun will chair a workshop dedicated to Food byproducts valorization through polyphenols extraction. Business creation from lab to market which will be held one day before the congress, on September 22, 2021.
