Abstract

Tea, due to its taste, color, pleasant aroma, and calming properties, holds a special place among beverages in many countries, including Afghanistan. Additionally, tea received the interest of scientists due to its antioxidant qualities, which originate from the polyphenols it contains. The aim of this article is to identify the antioxidants present in tea by the cyclic voltammetry (CV) method and to compare CV with other methods. An important stage in the tea industry is measuring the antioxidant activity and capacity of tea to find out how much polyphenols are present. For this purpose, various methods have been developed, each with its own advantages and disadvantages, and in this research, it was found that cyclic voltammetry is a suitable, rapid, simple, and cost-effective method for the identification and measurement of antioxidants present in tea.
