Anthocyanin Accumulation in Berry Fruits and Their Antimicrobial and Antiviral Properties: An Overview

Abstract

Because of the recent global crises and lifestyle trends, anthocyanin-rich fruits are receiving more attention due to their medicinal qualities. Many studies have concluded that higher anthocyanin consumption tends to correlate with health benefits. Furthermore, research has shown great promise for anthocyanin application in treating fever and neurodegenerative processes. Once the industrial application difficulties are solved, anthocyanins might prove to be a crucial component in helping to treat the diseases that are becoming more common—viral infections and illnesses associated with aging. Fruit extracts that contain large quantities of anthocyanins have antimicrobial and antiviral (against SARS-CoV-2 virus) properties. Most of the synthesized anthocyanins in the fruit-bearing fruits are stored in the fruits. The aim of this review article is to indicate the fruit species that have the most potential for anthocyanin extraction from fruits, to overview the antimicrobial and antiviral capabilities of anthocyanin and the main sample preparation and extraction methods that preserve polyphenolic compounds and reduce the time expenditure.
