The difference between black tea and Pu-erh tea

Tea is a common drink in our daily life. Tea tastes different from different types of tea. So what kind of tea is good? It depends on your preference! Here's a look at the two teas together.

The difference between black tea and Pu-erh tea

Pu'er tea is made from large-leaf tea tree tea in a specific region of Yunnan, and is made into sun-dried tea. It is produced through a special fermentation process and is divided into pressed tea, loose tea, ripe Pu'er tea and Pu'er tea.

Black tea belongs to fully fermented tea and is named after its black product. It is mainly distributed in Sichuan, Yunnan, Hubei, Hunan and Shaanxi.

On the choice of materials

Pu'er tea must be large leaf tea tree tea. Black tea This can be made with shrub tea.

Fermentation process

Pu'er tea belongs to semi-fermented and post-fermented tea. Black tea is fully fermented tea.

Color on

Pu-erh tea can clearly show the fresh activity of tea, while cooked tea shows brown-red. After the black tea was fully fermented, it turned black and black.

Other differences

Black tea is made by directly fermenting the enzyme activity of tea leaves after high temperature autoclaving. Pu'er tea cooked tea is fermented by wolfberry heap, using low-temperature watering. Pu'er tea is fermented in the later stage of the process.

Which is better for black tea and pu-erh tea?

Black tea is also good, but in terms of leaf species, it is two kinds of pure and different, Pu'er tea is a large leaf tea, which contains more should be rich, more and more fragrant, should choose Pu'er tea.

Each type of tea is good or bad. It depends on what kind of tea you like to drink. The tea itself is the best.

The effect and function of black tea

Digestive oil

Black coffee in the caffeine, vitamins, amino acids, phospholipids, etc. help the body to digest, regulate fat metabolism, caffeine stimulation can improve the secretion of gastric juice, thereby increasing appetite and help digestion.

Lipid-lowering diet

Black tea has a good degradation of fat, anti-hemagglutination, profibrinolytic activity and significant inhibition of platelet aggregation, but also to relax the blood vessel wall, increase the effective diameter of blood vessels, thereby inhibiting the atherosclerotic plaque and atherosclerotic plaque form. To achieve blood pressure, soften blood vessels, prevention and treatment of cardiovascular diseases.

anti-oxidation

The catechins, theaflavin, theanine and tea polysaccharides in black tea, especially the more complex flavonoids, etc., have the function of scavenging free radicals, and thus have the effects of anti-oxidation and delaying cell senescence.

Lower blood pressure and blood sugar

Caffeine and catechins in tea can relax blood vessel walls, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation. The black tea has the highest tea polysaccharide content and its component activity is stronger than other teas.

Lose weight and prevent arteriosclerosis

Tea polyphenols can significantly inhibit the increase of cholesterol and triglyceride (the main components of lipids) in the body, and can promote the excretion of lipid compounds from the body, and can also improve the elasticity of the capillary wall. Therefore, it plays an important role in the prevention and treatment of atherosclerosis, hypertension and obesity.

Prevention of coronary heart disease

According to statistical data, the incidence of coronary heart disease without drinking tea was 3.1%, and the occasional tea drinking was reduced to 2.3%, and tea drinking (more than 3 years) was only 1.4%. In addition, the increase in coronary heart disease is related to coronary insufficiency and thrombosis. The continuous oxidation of catechins and tea polyphenols in tea polyphenols during the decoction process to form tea pigments into animal in vitro tests all suggest significant Corning, fibrinolysis, and antithrombotic effects.

Hypertensive hypertension

Increased systolic or diastolic pressure, above normal levels. Arteriosclerosis not only causes coronary heart disease, but also has a close relationship with hypertension. Buck, that is, lower blood pressure. Tea polyphenols, vitamin C and vitamin P are all effective ingredients for preventing and treating hypertension. In particular, tea polyphenols improve the function of capillaries, and catechins and theaflavins have a significant inhibitory effect on the activity of angiotensin I-converting enzyme, which can directly lower blood pressure.

Anti-Aging

Lipid oxidation in the human body has proven to be one of the mechanisms of human aging. The use of compounds with antioxidant properties such as vitamin C and E can delay aging, and tea polyphenols also play an important role. According to research by Japanese scholars, the antioxidative effect of vitamin E, which has been used for anti-aging, has been only 4%, while the green tea is printed with polyphenols, and its antioxidant effect is higher than 74%. In addition, the amino acids and trace elements of tea also have certain anti-aging effects.

aid digestion

Caffeine and flavanols in tea can increase the motility of the digestive tract and thus aid in the digestion of food.

Anticancer

The anti-cancer effect of tea refers to the prevention and control of various malignant tumors. The Chinese Academy of Preventive Sciences has conducted in vivo and in vitro tests on more than 140 kinds of tea in vivo. A large amount of data indicates that tea has anti-cancer and anti-mutagenic effects. It mainly has a blocking effect on the formation of human carcinogenic nitroso compounds. Polyphenols and catechins in tea can inhibit certain enzymes that can activate carcinogens, and can also interact with the ultimate carcinogenic metabolism of electrophiles to alter their activity, thereby reducing the initiation and promotion of proto-oncogenes. , so that the final number of carcinogens decreased. Compared with a large number of people, it is also proved that tea drinkers have a lower incidence of cancer. Recent research shows that the chemical composition of green tea can also stop an important molecule in the development of cancer. This means that the anti-cancer ability of green tea is stronger and more diverse than scientists have guessed. Polysaccharides are mainly indirectly through the enhancement of the body's immune function to achieve the purpose of killing tumor cells.

Hangover

Tea hangover, because the liver in the process of alcohol hydrolysis requires vitamin c as a catalyst, tea, you can add vitamin c, is conducive to the decomposition of alcohol in the liver. On the other hand, the diuretic effect of caffeine in tea causes the rapid excretion of alcohol from the body, and it can also excitement in the brain center of inhibition in the presence of alcohol, thus playing an anti-alcoholic effect.

Diuresis

Modern studies have shown that the caffeine and theophylline contained in tea have a significant diuretic effect by expanding the renal microvasculature, increasing renal blood flow and inhibiting the reabsorption mechanism of renal tubular water.
