What does tea contains?

Tea, as a beverage, is primarily made from the leaves of the Camellia sinensis plant, but can also include other plants and flavors. Here's a breakdown of what tea contains:

Basic Components:

* Water: The main ingredient in tea, acting as a solvent for the other components.

* Caffeine: A stimulant found in tea leaves, contributing to its alertness-inducing effect.

* Theanine: An amino acid found specifically in tea, known for its calming and relaxing effects.

* Polyphenols: Antioxidants that contribute to tea's potential health benefits. These include:

* Catechins: The most abundant polyphenols in tea, such as epigallocatechin gallate (EGCG).

* Theaflavins and Thearubigins: These develop during oxidation (fermentation) in black tea, contributing to its color and flavor.

* Flavonoids: Pigments that contribute to tea's color and may also have antioxidant properties.

* Minerals: Tea contains small amounts of minerals like potassium, magnesium, and manganese.

Other Ingredients:

* Sugar: Often added to tea for sweetness.

* Milk: Added to tea, especially black tea, to create a milky tea.

* Other Flavorings: Various herbs, spices, and fruits are often added to tea to create different flavors.

Types of Tea:

The amount of each component in tea varies depending on the type of tea, the processing method, and the origin of the tea leaves. Here are some key differences:

* Black tea: Most oxidized, resulting in a strong flavor and dark color. Contains more theaflavins and thearubigins.

* Green tea: Minimally oxidized, resulting in a lighter flavor and color. Contains more catechins.

* White tea: Least processed, resulting in a delicate flavor and light color. Contains a high amount of antioxidants.

* Oolong tea: Partially oxidized, resulting in a variety of flavors and colors, depending on the level of oxidation.

* Herbal teas (infusions): Made from various herbs, flowers, and fruits, and do not contain caffeine or theanine.

Overall, tea is a complex beverage with a diverse range of components that contribute to its flavor, aroma, and potential health benefits.
