There are many kinds of tea in the world, including milk tea, oil tea, barley tea and so on. However, the two most popular types of tea are black tea and green tea. These two teas are also made into drinks and have very high sales in supermarkets. Do you know the difference between black tea and green tea? Let’s learn about tea drinking culture in this issue!

Different appearance:

Black tea has red leaves and red soup, which is a quality characteristic formed after fermentation. The dry tea has a dark color, a mellow and sweet taste, and a bright red soup color. Black tea includes "Kongfu Black Tea", "Red Broken Tea" and "Suchong Black Tea".

Green tea is the most produced type of tea in my country and is an unfermented tea. Green tea has the quality characteristics of green leaf clear soup. New tea with good tenderness has green color, exposed bud peaks and bright soup color.

Different effects:

Black tea is a fully fermented tea. It is characterized by a red soup after brewing. It is sweet and warm in taste. It is rich in protein and has the functions of refreshing the mind, relieving fatigue, etc. effect. The red leaves and red soup of black tea give people a feeling of warmth; milk or sugar can be added to black tea, which has the effect of generating heat and warming the stomach; black tea helps digestion and removes greasiness, which is beneficial when replenishing fat in winter.

Green tea retains more of the natural substances of the fresh leaves. Among them, tea polyphenols and caffeine retain more than 85% of fresh leaves, chlorophyll retains about 50%, and vitamin loss is less, thus forming the characteristics of green tea: "clear soup, green leaves, strong astringent taste". Scientific research shows that the natural ingredients retained in green tea have certain effects on anti-aging, anti-cancer, anti-cancer, sterilization, and anti-inflammatory.

Tea has medicinal values ??such as lowering blood lipids and preventing vascular sclerosis. Summer is hot, so it is advisable to drink green tea, which has a bitter and cold taste. It has the functions of clearing away heat, relieving 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.

The water temperature for brewing tea is different:

High-end green tea, especially famous green tea with delicate buds and leaves, is generally brewed with boiling water at about 80°C. If the water temperature is too high, it will easily destroy the vitamin C in the tea, and the caffeine will easily precipitate, causing the tea soup to turn yellow and taste bitter.

To brew various scented teas, black teas, and mid-to-low-end green teas, you need to use boiling water at 90-100°C. If the water temperature is low, the active ingredients in the tea leaves will be less precipitated, and the tea leaves will have a weak taste.

Different production processes:

In terms of processing technology, black tea is a fully fermented tea, which is made from the buds and leaves of the tea tree and undergoes typical processes such as withering, rolling, fermentation, and drying. Refined by process. Green tea is a non-fermented tea. It is made from the new leaves of the tea tree without fermentation, and is made through typical processes such as curing, kneading and drying. After fermentation, the chemical reaction of tea polyphenols in black tea is reduced by more than 90%, and new components such as theaflavins and thearubigins are produced.

Green tea has not been fermented, so it retains many of the original ingredients in tea. It also contains tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients. Because there are differences in the natural nutrients contained in these two types of tea, there are differences in the efficacy and effects of the tea between the two.

Different effects:

Black tea can help gastrointestinal digestion, promote appetite, diuresis, eliminate edema, and strengthen myocardial function. In terms of disease prevention: Black tea has strong antibacterial power. Gargling with black tea can prevent colds caused by viral viruses, prevent tooth decay and food poisoning, and reduce blood sugar levels and high blood pressure.

Green tea can scavenge free radicals, delay aging and prevent cancer. Regular drinking of green tea can prevent cell gene mutations, inhibit the growth of malignant tumors, lower blood lipids and blood pressure, prevent cardiovascular diseases, and can also prevent colds, dental caries, and eliminate bad breath.

Conclusion Although they are all tea, the mothers are different, and the children born are definitely different, and the effects are also very different. Black tea and green tea basically have nothing in common except that they are both teas.
