A brief review on emerging trends in global polyphenol research

Abstract

This article is focused on the global trend in research with special emphasis on the economic importance of polyphenols. We examined some of the media used for the formulation of polyphenol-enriched products. The levels of polyphenol extract production, international research funding, and number of published research work were determined from various databases and publicly available reports. The quantity of industrially extracted polyphenols was estimated to be 16,380 tons in 2015 and this is anticipated to reach a total of 33,880 tons by the end of 2024 with an estimated monetary value of USD 1.33 billion. Industrial utilization of polyphenol is dominated by the functional beverages sector (44%), followed by functional foods (33%) primarily due to high demands for polyphenol-rich consumables. Within a 10-year period, the number of polyphenol-related publications doubled from 2006 (1,574) to 2012 (3,330) and almost tripled in 2015 (4,213). Practical applicationsPolyphenols remain one of the most researched bioactive food compounds because of their wide distribution in nature and also due to their versatility as agents that can improve human health and enhance the shelf-life of foods. This report combines available scientific knowledge on the various factors that dictate polyphenol synthesis in plants, extraction methods, and utilization. The report also provides information on global polyphenol research and project funding history, which could serve as a critical reference for researchers all over the world.

Antifungal stilbene impregnation: transport and distribution on the micron-level

“…Today, more than 8000 plant phenolics are known and are classified into two main groups, either flavonoid or non-flavonoid compounds ( Strack and Wray 1994 ). These plant-associated substances are currently a hot topic in a wide range of research areas ( Savio et al 2016 , Berman et al 2017 , Adebooye et al 2018 , Arif et al 2018 , Donado-Pestana et al 2018 , Halake et al 2018 ). In particular, the 3,4′,5-trihydroxystilbene, known as resveratrol, has attracted a lot of research attention ( Bostanghadiri et al 2017 ).…”

Recent Advances in the Analysis of Rosmarinic Acid From Herbs in the Lamiaceae Family

“…It is one of the biggest challenges for analysts due to the large number and variety of natural phenolics in different classes. 19,20 This review includes the latest research in high-performance liquid chromatography (HPLC) analysis of RA from herbs in the Lamiaceae family.…”

Structure and Function of Mung Bean Protein-Derived Iron-Binding Antioxidant Peptides

“…Metal chelation is an important mechanism by which antioxidants attenuate oxidative stress. This is because free iron molecules are involved in initiating and perpetuating the Fenton reaction [ 42 ]. By sequestering iron molecules, peptides can reduce the production of toxic free radicals, including lipid peroxidation.…”
