Introduction to hualai black tea knowledge. Tea is a common drink in our daily life. Many people use tea to entertain guests, but tea has a long history of development. I collected and sorted out the relevant information about the introduction of Hualai black tea for everyone. Let's have a look.
Introduction to Hualai Black Tea 1 Introduction to Tea Knowledge
About 700 aromatic compounds have been invented in tea. The types and contents of aroma components in various teas are different. The wonderful combination of these identities has formed the unique personality charm of black tea. Examples of fragrance include: incense, grass fragrance, rose fragrance, osmanthus fragrance, jasmine fragrance, orchid fragrance, violet fragrance, daffodil fragrance, coconut fragrance, fruit fragrance, woody fragrance, resin fragrance, roasted fragrance, honey fragrance, agarwood and so on. After the aroma of tea is inhaled into the human body, it will lead to changes in brain waves, changes in the affinity of neurotransmitters and their receptors, and anti-α S mechanical pleasure effects caused by two brilliant components such as blood pressure, some of which are sedative effects, and so on. The aroma released by old tea over 0 years old is still old and lasting.
The aroma components in black tea have many results. Such as sedation, analgesia, rest, antibacterial and anti-inflammatory, virus killing, deodorization and so on. About 700 aromatic compounds have been invented. When drinking black tea, the aroma components of tea enter the body through the mouth and nose, which makes people feel refreshed. Human experiments have found that the aroma components of black tea act on the central nervous system after inhalation, causing changes in brain waves, conduction and affinity between neurons and blood pressure. Different ingredients will cause different reactions in the brain, and the effects of pleasure and sedation are coordinated with each other, which plays a comprehensive regulatory role in the human body.
Introduction to Hualai black tea knowledge
According to a survey report on smoking jointly completed by the World Health Organization (WHO), the British Imperial Cancer Research Foundation and the American Cancer Society, every 10 second in the world, 1 people die from diseases caused by smoking. The harm of smoking begins with the free radicals produced by nicotine and its comprehensive components. Some scientists have done tests. Smoking a cigarette produces 6,543,800,000 free radicals (as does secondhand smoke). Too many free radicals will induce the oxidation of unsaturated fatty acids in the body, produce lipid peroxides and cause oxidative polymerization of protein. Unsaturated fatty acids are important substances in cell membrane layout. The occurrence and accumulation of free radicals will weaken and damage the normal function of cells, lead to structural necrosis, affect the normal metabolism in the body, and thus induce diseases and aging of the body.
There are many oxidases in organisms, such as xanthine oxygenase, P-450 enzyme system, lipoxygenase, cyclooxygenase and so on. Can catalyze the formation of free radicals in the body. Tea polyphenols in black tea and Poria cocos tea can inhibit and destroy these oxidases. At the same time, there is an antioxidant system (free radical scavenging system) in the organism, which includes catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH) and other antioxidant enzymes. These enzymes can accelerate the elimination of free radicals under the action of tea polyphenols and prevent the body from being damaged by reactive oxygen species. Tea polyphenols can also strengthen the enzyme activity of antioxidant system in liver, lung, digestive system, blood and other structures, and play a role in shielding oxidase in the body.
In animal experiments, it is also found that the intake of tea polyphenols can inhibit the occurrence of lipid peroxide, maintain the concentration of antioxidants such as vitamin C and E in the body, and inhibit the damage of free radicals to DNA.
Introduction to Hualai Black Tea 2 Efficacy of Hualai Black Tea
1, improving carbohydrate metabolism, lowering blood sugar and preventing and treating diabetes.
Tea polysaccharide complex in black tea is the main component of lowering blood sugar. Tea polysaccharide complex, usually called tea polysaccharide, is a complex and diverse mixture. Due to the action of glycosidase, protease and hydrolase, relatively short sugar chains and peptide chains are formed, and short peptide chains are easier to be absorbed and have stronger biological activity, which may be one of the reasons why fermented tea, especially Anhua black tea polysaccharide, has better hypoglycemic effect than other teas.
2, sterilization, anti-inflammatory
The main components of dark tea soup color are theaflavins and thearubigins. Studies have shown that theaflavins are not only an effective free radical scavenger and antioxidant, but also have obvious antibacterial effects on Botox, Enterobacteriaceae, Staphylococcus aureus, Clostridium perfringens and Bacillus cereus. In addition, theaflavins can also inhibit the invasion of influenza virus and the infection of rotavirus and enterovirus.
3, diuretic detoxification, reduce the toxicity of tobacco and alcohol
The diuretic effect of caffeine in black tea is realized by the kidney promoting the filtration rate of water in urine. At the same time, the stimulating effect of caffeine on bladder not only helps diuresis, but also helps sober up and relieve alcoholism.
At the same time, tea polyphenols in black tea can not only precipitate nicotine in tobacco and excrete it with urine, but also remove free radicals in smoke and reduce the toxic effect of smoke on human body. Tea polyphenols have a strong adsorption effect on heavy metal poisons, so drinking more tea can also alleviate the toxic effect of heavy metals.
4. Dietary nutrition
Black tea is rich in nutrients, the most important of which are vitamins and minerals, as well as protein, amino acids and sugars. It is called the tea of life.
5, help digestion and oil production.
Caffeine, vitamins, amino acids, phospholipids and so on. Black tea helps the human body to digest and regulate fat metabolism. The stimulation of caffeine can improve the secretion of gastric juice, thus increasing appetite and helping digestion. Japanese scholars have proved through scientific experiments that black tea has a strong function of relieving greasy and helping digestion, which is why meat eaters especially like this kind of tea.
6. Reduce fat and lose weight
Black tea has good effects of degrading fat, anticoagulation, promoting fibrinogen dissolution and significantly inhibiting platelet aggregation. It can also relax the wall of blood vessels and increase the effective diameter of blood vessels, thus inhibiting the formation of atherosclerotic plaques on the inner wall of aorta and coronary artery. Achieve the purpose of lowering blood pressure, softening blood vessels and preventing and treating cardiovascular diseases.
7. Anti-oxidation
Black tea is not only rich in catechins, tea pigments, flavonoids, vitamin C, vitamin E, D- carotene and other antioxidant substances, but also contains a large number of trace elements with antioxidant effects such as zinc, manganese, copper (the constituent element of SOD) and selenium (the constituent element of GSHPX). Catechins, theaflavins, theanine and tea polysaccharides in black tea, especially compound flavonoids with high content, all have the function of scavenging free radicals, so they have the functions of antioxidation and delaying cell aging.
8, lower blood pressure
Lou Fuqing, China, et al. found that tea pigment has obvious effects of anticoagulation, promoting fibrinolysis, preventing platelet adhesion and aggregation, and inhibiting the proliferation of arterial smooth muscle cells. It can also significantly reduce triglyceride and low-density lipoprotein in serum of high-fat animals, increase high-density lipoprotein in serum, significantly inhibit ACE enzyme, and has antihypertensive effect.
9, radiation protection
Tannin polyphenols in black tea can combine with radioactive substances such as strontium, and even promote the excretion of strontium from bone marrow. Excretion with feces; Lipopolysaccharides and tannins can resist radiation damage.
Nutritional value of Hualai black tea
1, clear fat, lose weight and gain weight
Polyphenols and their oxidation products in black tea can dissolve fat and promote the discharge of lipid substances; It can also activate protein kinase, accelerate fat decomposition and reduce body fat content. Therefore, Anhua black tea is called "slimming tea" by Koreans; Japanese people call it "beauty tea"; People in Taiwan Province Province call it "Xiaoshi Tea".
2, clear the stomach, help digestion
Black tea is rich in dietary fiber and has the function of regulating stomach and clearing stomach; And with the participation of probiotics, it can improve the intestinal microbial environment and help digestion. In China, there is a tradition of using old black tea to treat abdominal distension, dysentery and indigestion.
3, dredge blood vessels, reduce the three highs
Black tea is rich in theaflavins, which can soften blood vessels and effectively remove atherosclerotic substances from blood vessel walls, and is called "cardiovascular scavenger"; Theanine can effectively inhibit the increase of blood pressure, and flavonoids can relax the wall of blood vessels, increase the effective diameter of blood vessels and reduce blood pressure; Tea polysaccharide has similar effect to insulin, reducing blood sugar content; Polyphenols and their oxidation products can dissolve fat, promote the excretion of lipid substances in blood vessels and reduce the content of cholesterol in blood.
4. Remove toxins and protect liver and kidney.
The unique functional factors of probiotics, polyphenol oxides, catechins and other complex components in black tea participate in human metabolism, and have a special purification function for human internal organs, adsorb toxic substances (alcohol, heavy metals, body garbage) and excrete them, which can deeply detoxify; It can also inhibit bacteria and protect liver and kidney.
