The difference between black tea and green tea

The difference between black tea and green tea

1. The appearance difference between black tea and green tea

Judging from the appearance of the tea leaves, green tea leaves show bright buds, fresh soup, rich aroma, and mellow taste, turning into green tea color, while black tea leaves show bright color, bright red leaves at the bottom, rich aroma, and long-lasting aroma.

2. The difference in color of tea soup between black tea and green tea

A few minutes before brewing, black tea is light brown; green tea soup is clear green. After more than half an hour of brewing, black tea is brown, and good green tea is still green. Green tea is bright, green or dark green, while black tea is light or dark brown.

3. Differences in the production process of black tea and green tea

In terms of processing technology, black tea is a fully fermented tea, which is extracted from tea buds and leaves through the typical withering, crushing, fermentation, and drying processes. Green tea is a non-fermented tea. It is made from unfermented new leaves of the tea tree and goes through the typical processes of blanching, kneading and drying. After fermentation, the chemical changes caused by theanine in green tea are reduced by more than 90%, and new components such as theaflavins and thearubigins are formed.

As everyone knows, green tea leaves have not undergone fermentation, so they retain many of the original ingredients of tea and contain many nutrients, such as theanine, catechins, chlorophyll, caffeine, carbohydrates, vitamins, etc. Because the two types of tea have different natural nutrients, the functions and effects of the two types of tea are different.

4. Differences in the efficacy and functions of black tea and green tea

The functions and effects of black tea: Black tea contains a lot of phenolic substances. Although the relative molecular weight of these phenolic substances is quite large, black theanine is very different. As everyone knows, clinical research results show that it also has antioxidant properties, lowers blood lipids, inhibits myocardial infarction, improves capillary function, and resists sudden changes. Black tea contains lipopolysaccharide, so drinking black tea can also lower blood sugar. Black tea has strong bactericidal and anti-inflammatory effects.

The efficacy and function of green tea: Green tea retains more of the natural substances of the fresh leaves. Among them, theanine and caffeine retain more than 85% of the tea green, and the chlorophyll retains about 50%, with less vitamin damage, thus bringing about the characteristics of green tea “white soup with green leaves, strong flavor and astringency”. Studies have shown that the natural compounds stored in green tea leaves have anti-aging, cancer prevention, cancer prevention, germ removal and anti-infective properties. Tea has medicinal values such as lowering blood lipids and preventing vascular sclerosis. When summer is hot, consider consuming the bitter herbal green tea as appropriate, which has the effects of clearing away heat, detoxifying, and quenching thirst. Green tea contains high amounts of tea polyphenols, caffeine, amino acids, etc., which can stimulate the oral mucosa, promote the secretion of digestive glands, and is beneficial to the production of body fluids. It is a good product for relieving summer heat and quenching thirst.
