Introduction to Tea Testing

Tea contains catechins, folic acid, pantothenic acid, caffeine, inositol and other ingredients to enhance human health. Tea is known as "one of the world's three major beverages." In order to maintain the credibility of tea, to promote the prosperity of the tea market, and to protect the interests of consumers, the International Standardization Organization-Agricultural Food Technology Committee Tea Subcommittee recommended the international standards and testing methods for tea.
