Topics for Discussion
International scientific conferences on polyphenols contained in foods are now exploring the beneficial health effects of foods such as coffee and tea. One such conference structured the following discussions of health benefits:
The following topics will be treated
Topic 1 : Polyphenols in Human Health
clean hotel ZandvoortMedicinal plants rich in polyphenols have been used in the treatment of diseases for several thousand years. Today it is realized that polyphenols present in food and beverages also contribute to the prevention of diseases and upholding of a good state of health. Communications will focus on:- the demonstration of their activity in vivo
- the mechanisms of action
- their bioavailability
Topic 2 : Chemical and Biochemical Synthesis of Polyphenol
The difficulty in obtaining polyphenols of a defined structure and composition limits considerably the study of their biological properties.The aim of this session is to revise recent development of polyphenol synthesis by chemical and biochemical means. The following molecules will be considered:- labeled molecules
- analogues with specific properties
- oligomers of defined composition and stereochemistry
- polyphenol conjugates
Topic 3 : Polyphenols in Food and Consumer Preference
Red color of fruits, vanilla aroma and wine astringency are all explained by the presence of polyphenolic compounds. Polyphenols have a major influence on color, aroma and taste and will affect the final consumer choice. Communication will focus on:- polyphenols and food quality
- polyphenols and sensory analysis
- polyphenols and physiology of food quality perception
Topic 4 : Polyphenols and Stress Resistance of Plant
Mechanisms of plant defense against stress imposed by biotic (e.g. pathogens) and abiotic (e.g. UV radiation) factors are diverse and complex. Polyphenols, either constitutive or inducible, are one of the important components of the defence strategies developed by plants during evolution. Communications will concern:- polyphenol biosynthesis in response to stress
- regulation of the expression of polyphenol biosynthetic pathways
- molecular approaches for reducing or enhancing the accumulation of polyphenols in plants

Plant polyphenols are present in various food additives either as a coloring agent or as an antioxidant. An important development outlook appearstoday in many a field e.g. dietary supplements, beauty products or packing. The following specialties will be considered:- food additives
- nutraceuticals
- cosmetics
- polyphenol polymers
Topic 6 : Polyphenols in the Biosphere
Polyphenols are major secondary metabolites setting the balance between plant, animal and micro-organism species. Synthesized in plant tissues, degraded by micro-organisms in the soil or in the animal gut, discarded in the course of human activities, understanding their role and evolution in the biosphere is essential for its preservation. The following aspects will be covered:- polyphenols as deterrent agents
- polyphenols as signal molecules
- biodegradation of polyphenols
- polyphenols in soil and water
