About this Research Topic
Natural phenolic compounds are widely represented in nature, not only in foods but also in easily accessible sources such as waste materials from agri-food industries. This class of compounds has gained more and more attention because of the beneficial effects to human health in the prevention of cancer and cardiovascular diseases. Most of the biological properties of natural phenols have been ascribed to their potent antioxidant and scavenging properties against reactive oxygen species generated in settings of oxidative stress, which are responsible for the onset of several inflammatory and degenerative diseases. Evaluation of the actual bioavailability of phenolic compounds based on data concerning their absorption, metabolism, tissue, and organ distribution represents another crucial point to establish their effects on the human body. In addition, the understanding of the metabolic fate of phenols due to their interaction with the gut microbiota is an issue to be solved in the next years.
Apart from their use as food supplements or as additive in functional foods, in the last years natural phenolic compounds have become increasingly attractive also from a technological point of view, due to their possible exploitation in materials science, with particular reference to biomedical, active packaging and technological applications. Such interest has also been prompted by the increasing need for green and sustainable approaches to novel, functional materials.
This Research Topic welcomes original research articles describing sustainable approaches for the recovery of functional phenolic compounds from agri-food wastes and other natural sources. Structural characterization of the recovered material as well as characterization of relevant properties for their exploitation as additives in functional materials or for e.g. health, food, and/or cosmetic applications is mandatory. Methodological articles presenting novel approaches for the measurement of the impact/benefits of the isolated phenolic compounds in the different application fields, e.g. to the food supply and to human nutrition and health will be also considered for publication. Potential topics include also the description of novel effects, mechanisms of action, bioavailability data, and unintended consequences of long term consumption of the isolated phenolic compounds. Review articles describing the current state of the arts are also welcome.
