Hemisynthesis of anthocyanin phase II metabolites and their characterization by LC-ESI-IMS-QTOF mass spectrometry

Sarah Schmitt will speak about "Hemisynthesis of anthocyanin phase II metabolites and their characterization by LC-ESI-IMS-QTOF mass spectrometry" during the Malta Polyphenols 2019 Congress.

Sarah Schmitt from the University of Bonn, Germany will join the Malta Polyhenols 2019 Congress which will be held on September 30 and October 1st, 2019 in Malta.

Sarah Schmitt highlights: Until today, little is known about the biological activity of the phase II metabolites of anthocyanins. Among other reasons, especially the poor commercial availability and the high prices of the phase II metabolites pose a significant hindrance in the identification and quantification. Therefore, strategies for their synthesis are required, which may include chemical and enzymatic approaches. Novel techniques such as ion mobility mass spectrometry are promising for the analytical characterization of compounds and may serve as a basis in the search for metabolites formed in vivo”.

Phenolic compounds from wine industry by-products: characterization and in vitro bioaccesibility

Dr. Ariel Fontana will give a presentation entitled "Phenolic compounds from wine industry by-products: characterization and in vitro bioaccesibility".

Malta Polyphenols 2019 Congress welcomes Dr. Ariel Fontana from Universidad Nacional de Cuyo (UNCUYO), Argentina.

Summary of talk: The wine industry generates a large volume of wastes, including those by-products produced before, like pruning residues (canes), and along the winemaking process such as pomaces and stems. The increase of consumers’ concerns about the use of additives in alimentary products and the attention that functional foods have attained in the last years prompted the identification of alternative sources of natural antioxidants. Several compounds present in winemaking by-products such as phenolic compounds have shown health-promoting effects and other biological properties mostly related to their antioxidant characteristics. The characterization of compounds is therefore a necessary step to increase the worth and justify their application in food industries. As well, in vitro gastrointestinal simulation is a valuable tool for investigating the effect of digestion on the phenolic compounds bio-accessibility. This approach contributes to assess the nutritional quality of a bioactive compound while encourages the development of functional foods. This talk will focus on the characterization of phenolics from winemaking by-products of Vitis vinifera L. cv. Malbec and the properties of extracts after in vitro digestion with the aim to establish their bio-accessibility

Influence of juice processing and natural variation in the bioaccessibility of phenolics from grapes and blueberries

Prof. Mario Ferruzzi will talk about his study on Influence of juice processing and natural variation in the bioaccessibility of phenolics from grapes and blueberries.

The Organizing Committee of Malta Polyphenols 2019 Conference is honored to announce the participation of Prof. Mario Ferruzzi from North Carolina State University, USA.

Summary of Talk: The food matrix is known as a modifier of polyphenol bioavailability.  The matrix itself is influenced by genetics, agronomic conditions as well the ultimate food process chosen for production.  For example, juicing and pasteurization of purple grapes modifies both the food matrix (fractionation, structure) and polyphenol profiles (content) influencing ultimate bioaccessibility of polyphenols for uptake/metabolism by humans or the microbiota.  Additionally, while diversity in content of phenolics is commonly studied in fruit germplasm/breeding populations, variation in phenolic bioaccessibility remains largely unknown.   Exploration of natural diversity of phenolic bioaccessibility in blueberry germplasm is beginning to provide insights into matrix effects and will potentially yield genetic targets for improvement of polyphenol bioavailability from fruit products.

Epigenetic modulation of inflammation and synaptic plasticity by polyphenolic metabolites promotes resilience against stress in mice

Prof. Giulio Maria Pasinetti from Icahn School of Medicine at Mount Sinai, USA will join the Malta Polyphenols 2019 Congress and give a presentation entitlled "Epigenetic modulation of inflammation and synaptic plasticity by polyphenolic metabolites promotes resilience against stress in mice".

Summary of presentation: Major depressive disorder is associated with abnormalities in the brain and the immune system. Here, through a high-throughput screening, we identify two phytochemicals, dihydrocaffeic acid (DHCA) and malvidin-3'-O-glucoside (Mal-gluc) that are effective in promoting resilience against psychological stress-induced depression. We discuss the ability of DHCA/Mal-gluc to significantly reduces  depression-like phenotypes in a mouse model of increased systemic inflammation induced by transplantation of hematopoietic progenitor cells from stress-susceptible mice. DHCA reduces pro-inflammatory interleukin 6 (IL-6) generations by inhibiting DNA methylation at the CpG-rich IL-6 sequences introns 1 and 3, while Mal-gluc modulates synaptic plasticity by increasing histone acetylation of the regulatory sequences of the Rac1 gene. This study suggests that polyphenolic metabolites capable of influencing peripheral inflammation and synaptic maladaptation may eventually be implemented as novel therapeutic interventions for promotion of mental health.

Natural and bioinspired phenolic compounds as skin depigmenting agents: Recent Advances

The Organizing Committee of Malta Polyphenols 2019 Conference is honored to announce the participation of Dr. Lucia Panzella from the University of Naples "Federico II", Italy.

Dr. Panzella will speak about "Natural and bioinspired phenolic compounds as skin depigmenting agents: Recent Advances" during the special session dedicated to Polyphenols and Skin.

Dr. Panzella highlights: "Several skin pigmentary disorders are associated with the overproduction of melanin as the result of an abnormal function of melanocytes. One of the most common approach for control of pigmentation involves the inhibition of tyrosinase, a copper-containing enzyme which catalyzes the key steps of melanogenesis. The talk will focus on the tyrosinase inhibition properties of a series of natural and bioinspired phenolic compounds for the development of novel depigmenting agents."

During this special session, Malta Polyphenols 2019 Speakers will highlight the strategic roles of polyphenols and phenolics compounds as antioxidants (anti-UV) and anti-inflammatory agents. We will also discuss the polyphenols formulation and skin pigmentation. We will dedicate time to all innovations related to polyphenols'  use in skin care and skin aging.

You can submit your Abstract and innovation before July 15, 2019.

Use of nanosystems to improve delivery of polyphenols for skin repair

Dr. Carla Caddeo  will give a presentation entitled "Use of nanosystems to improve delivery of polyphenols for skin repair" during the Special session dedicated to Polyphenols and Skin.

Dr. Carla Caddeo from the University of Cagliari, Italy will join the 13th World Congress on Polyphenols Applications: Malta Polyphenols 2019 which will be held in Malta on September 30 -  October 1, 2019.

Summary of presentation: The beneficial health effects of polyphenols have been extensively studied in the past years. However, their potential therapeutic and prophylactic applications are restricted by low bioavailability, poor water solubility and stability. In this framework, nanoparticulate systems are gaining increased attention as innovative delivery systems for poorly bioavailable compounds, as they ensure high stability, incorporation of hydrophilic/hydrophobic substances, high carrier capacity, and feasibility of various administration routes. Additionally, they can be designed to allow controlled release of the payload, thus enabling reduction of dosing frequency: bioefficacy is amplified and side-effects and costs are reduced, while increasing patient compliance.

During this special session, we will highlight the strategic roles of polyphenols and phenolics compounds as antioxidants (anti-UV) and anti-inflammatory agents. We  will  also discuss the polyphenols formulation and skin pigmentation. We will dedicate time to all innovations related to polyphenols' use in skin care and skin ageing.

You can submit your Abstract and innovation before July 15, 2019.

"Our research group participated at the congress with two poster presentations, the results of the research, carried out under the international project SUSMEATPRO and Estonian University of Life Sciences financed project.

In preliminary tests (poster presented by Piret Raudsepp) different plant parts of different cultivars with the best antioxidative and antimicrobial properties were selected for further use as berry or vegetable powders in meat products. The product studies showed the capability of plant supplements to reduce bacterial load, inhibit lipid oxidation, prolong the shelf-life and improve sensory qualities of meat products. The ongoing and future research will be focused on plant powder blends and finding out specific polyphenolic compounds responsible for these beneficial effects.

We attended the World Congress on Polyphenols Applications for the first time and we enjoyed it very much. It was a well organized event, interesting oral presentations, plenty of room for posters and time to read, think and discuss. We met the researchers of different research fields willing to co-operate and representatives of food industry interested in our results. We got good memories and experience from this year. The recognition motivates us to continue our research, to achieve more interesting results and present our findings at forthcoming congresses".

Biosynthesis of acylphloroglucinols: novel phenolics from strawberry fruit

Prof. Wilfried Schwab from Technical University of Munich, Freising, Germany will talk about "Biosynthesis of acylphloroglucinols: novel phenolics from strawberry fruit" during the 12th World Congress on Polyphenols Applications: Bonn Polyphenols 2018 which will be held at the University of Bonn, Germany in September 25-28, 2018.

Summary of talk: "Polyphenolic compounds have health-promoting properties and are a major group of secondary metabolites in fruit crops. Through reverse genetic analysis of the functions of ripening-related genes in strawberry (Fragaria × ananassa) we discovered four acylphloroglucinol (APG)-glucosides as native Fragaria spp. fruit metabolites whose levels were differently regulated in the transgenic fruits. The biosynthesis of the APG aglycones was investigated by examination of the enzymatic properties of three recombinant Fragaria vesca chalcone synthase proteins."

Stabilization of anthocyanins by co-pigmentation using mango peel and rooibos phenolics

During the 12th World Congress on Polyphenols Applications: Bonn Polyphenols 2018, Judith Müller-Maatsch from University of Hohenheim, Germany will talk about "Stabilization of anthocyanins by co-pigmentation using mango peel and rooibos phenolics".

Short summary of talk: "Anthocyanins are highly susceptible to light exposure, temperature, and oxygen, thus, the color of anthocyanin-rich products lacks in stability during processing and subsequent storage. Anthocyanins’ susceptibility to degradation is primarily determined by their molecular structure and the surrounding matrix, i.e. pH, water activity, hydrocolloid content, and concomitant phenolic compounds named co-pigments. Co-pigmentation describes the interaction of anthocyanins and co-pigments that results in a modulation of color and a change in anthocyanin stability. Phenolics of mango peels as well as rooibos have been observed to effectively modulate the color of strawberry anthocyanins. Whereas phenolics based on gallic acid deriving from mango peel  pronouncedly modulated the color, phenolics from rooibos further increased the stability of anthocyanins during heating."
