Formulation and Development of a Functional Fermented Beverage from Guava Leaves

Abstract

There has been more interest in making functional drinks in the last several years because more people are looking for natural and health-promoting items. Guava leaves were chosen for the beverage's development because of their therapeutic effects on the human body (antibacterial, anti-inflammatory, and anti-diabetic), their high polyphenol, flavonoid, and antioxidant content. Guava leaves can be transformed into a novel fermented herbal drink, integrating traditional herbal uses with contemporary nutraceutical applications, which is the first step toward developing a novel beverage. This research aims to develop a functional beverage while utilizing guava leaves with various health benefits. This natural, health-driven novel beverage adheres to global consumer demands for inclusive, sustainable and nutrient-dense drinking options and provides artisanal and commercial sectors with a scalable solution to sustainable global demands for economic equity, environmental efficacy and health.
