As early as ancient times, people took note of the foam that showed up when making tea, as well as concerned this “white foam” as a kind of significance. In the Jin Dynasty (265-420) of our country, Du Yu stayed in the “Fu” in which there is a rhyme: “Weizi is simply created, as well as the foam is sinking and drifting. It is like snow, as well as it is like springtime.” Explains that after developing tea for the very first time, the thin soup flowers float up, brilliant and bright like dazzling snow, beautiful as well as brilliant like flourishing spring blossoms.
Now clinical research study has actually even more shown that the substance that can produce this “white foam” is called tea saponin. Tea saponin, likewise known as saponin, saponin, has the name of “saponin” because of its aqueous option as well as the ability to generate relentless, soap-like foam when oscillating. Saponins widely exist in more than 90 family members and more than 500 category of plants in nature. These plants consist of common oil crops such as soybeans and camellia oleifera, as well as unusual Chinese medical products such as ginseng, Codonopsis pilosula, Aescin, licorice, sand ginseng, and pulsatilla. In addition, some marine organisms such as starfish can likewise produce saponins.
Tea saponin is a kind of all-natural glycoside compound included in the Theaceae plant, which is a blend of a kind of oleanane-type pentacyclic triterpene saponins, and its fundamental framework consists of three components: saponin, sugar body as well as natural acid. Tea saponin has the generality of camellia plant saponins, it is an anemic ashless great columnar crystal with a melting point of 223 ~ 224 ° C, it tastes bitter and also poignant, it can foam and has hemolytic result. The crystals of tea saponin are insoluble in ether, chloroform, acetone benzene, oil ether and other solvents, barely soluble in cold water, outright ethanol as well as outright methanol, yet slightly soluble in warm water, carbon disulfide as well as ethyl acetate, and easily soluble in aqueous Amongst methanol, liquid ethanol, n-butanol, glacial acetic acid, acetic anhydride and also pyridine, its solubility increases dramatically in dilute alkaline aqueous solution.
Tea saponin is distributed in the origins, stems, leaves as well as seeds of the tea tree, but its molecular structure is different, resulting in distinctions in physical buildings. In regards to web content alone, the content of saponin in tea seeds is the highest, and also the web content of tea saponin in the whole seeds of different tea tree seeds varies.
The web content of tea saponin in tea seeds, like other plant components, is affected by the geographical location of the tea tree, ecological problems, tea tree kind, variety, seed maturity, and also the uniformity of the dimension of the fruit. my country’s tea location is large, and also the intricate eco-friendly conditions will have a profound effect on the web content of tea seed saponin.
For the application of tea saponin, old Chinese laborers have actually known for a long period of time to utilize tea seed cakes to saturate water for washing clothing and also hair. In the “Compendium of Materia Medica” released in 1590, there is a record of “tea seeds pounding kernels to clean clothes to eliminate greasy”, as well as this is exactly the effect of tea saponin in tea seed cakes. Since it was first isolated and uncovered by Japan Aoyama Jiro in 1931, tea saponin has actually been adequately and in-depth clinical study. Modern medical research study shows that tea saponin has medicinal features such as hemolysis as well as fish poisoning, anti-insect as well as bactericidal impacts, anti-osmosis and anti-inflammation, phlegm and cough, analgesia, anti-cancer, as well as the result of advertising plant growth. In addition, tea saponin additionally has various surface activities such as excellent emulsification, diffusion, wetting, purification, and also lathering, as well as is a natural surfactant with outstanding performance. Therefore, tea saponin is commonly utilized in cleaning, woollen spinning, weaving, medicine, daily chemical sector, building and construction industry and also various other areas.
Soaking tea seed cakes in water for cleaning as well as shampooing has existed in old times. Individuals usually believe that tea seed cakes can make hair soft and also glossy after washing, as well as can get rid of dandruff and also ease itchiness. In contemporary times, tea saponin, as a natural product, is an uncommon surfactant product in the daily chemical sector.
Using the surface activity of tea saponin, it can be utilized as shampoo, hair shampoo, etc. It not only makes the hair glossy and also really feels excellent, yet likewise is almost non-toxic, secure to use, has the impact of nourishing hair and also skin care, and lowers swelling as well as itching. Anti-dandruff result and also various other pharmacological features; as a matrix component, tea saponin can be utilized in sun block and also anti-inflammatory cream, soap, body clean, and so on.
Tea saponin can likewise be used to wash clothes. The all-natural nature of tea saponin and its non-destructive buildings to healthy protein as well as cellulose make tea saponin have incomparable benefits in washing woollen, silk, down, and so on, such as little removing ability., will not create milling, the fabric will not lose luster, etc. Therefore, in recent times, day-to-day chemical products of tea saponin have actually shown up constantly.
Saponin compounds have a damaging result on red cell of pet cells. Tea saponin in tea is the same as soybean and ginseng saponin compounds, which has really weak hemolytic activity; tea saponin is a lot more toxic to cold-blooded animals, particularly to fish. Tea saponin also reveals better toxicity when infused intravenously to other pets and also people, but the poisoning is extremely reduced when taken by mouth. Individuals do not require to worry about the hemolysis of tea saponin when consuming alcohol tea.
( 2) Antibacterial and also antiviral results.
Tea saponin has inhibitory effect on various fungi as well as Escherichia coli that trigger skin diseases. Tea saponin has inhibitory effect on An as well as B flu virus, herpes infection, measles infection and HIV infection.
( 3) Anti-inflammatory and also anti-allergic results.
Tea saponin has obvious anti-leakage as well as anti-inflammation characteristics. In the early stage of swelling, it can stabilize capillary permeability as well as works for bronchospasm as well as edema triggered by allergic reactions. Its effect is comparable to that of numerous anti-inflammatory medications.
( 4) The result of inhibiting the absorption of alcohol.
Tea saponin has the task of inhibiting the absorption of alcohol. In the experiment on mice, the computer mice were offered alcohol one hr after taking tea saponin, and it was located that the alcohol material in the blood as well as liver of the computer mice reduced, as well as the alcohol in the blood disappeared in a short time period. Tea saponin hinders the absorption of alcohol, advertises the metabolic process of alcohol in the body, and also has a safety effect on the liver.
( 5) Weight-loss effect.
Tea saponin can impede the activity of pancreatic lipase. Tea saponin can decrease the intestinal tract absorption of fat in food by impeding the task of pancreatic lipase, thus decreasing weight. Tea saponin also has the results of advertising the secretion of hormones in the body, regulating blood sugar level levels, decreasing cholesterol degrees, as well as reducing high blood pressure.
1. What is tea foam caused by?
The tea saponin in tea is working
Tea saponin is the main cause of tea foam. Tea saponin is also called tea saponin. It tastes bitter and pungent, and has a strong foaming power. Generally, tea with rich foam has a relatively strong taste. Scientific research shows that tea saponin has antibacterial, anti-inflammatory, analgesic and other effects, and is a substance beneficial to the body.
There is some fluff on the tea leaves
The fluff on the tea leaves is also one of the reasons for the formation of tea foam. Some teas made from tea buds are relatively tender and have more fluff, such as Biluochun, which will float tea hairs and bubbles when flushed, which looks dirty, but is actually essence.
There are some fragments in the tea
In addition, like crushed red tea, or tea leaves with a lot of powder, the effective substances in the tea are leached out quickly, and tea foam is more likely to be produced when brewing.
2. Good tea will not have tea foam, is it true?
Some people think that good tea has no foam, and the more foam there is, the worse the tea will be. Is this true?
Some people have found that the tea soup has foam in high-end Pu’er ancient tree tea, because there are more fluff on the tea sticks; in addition, some teas that are fermented heavily, the rich content sticks to the surface of the tea sticks, and it is easy to produce foam when brewing. Foam.
Tea foam is related to the brewing technique. If the hanging pot is poured at high speed, there will be more bubbles stirred up, but if the water is poured gently at low pressure, the tea foam will be less.
3. Do I need to scrape the tea foam to make tea?
On the one hand, tea foam is the essence of tea soup. Although the content of tea saponin is small, it is a component of the taste of tea soup. If there is less tea foam, the flavor of tea will be compromised. On the other hand, tea saponin has a certain antibacterial and anti-inflammatory effect, and it is beneficial and harmless to the human body.
Tea saponin is a kind of glycoside substance, which widely exists in the plant kingdom, such as traditional Chinese medicine tangerine peel and licorice, which contain glycoside substances.
The action of scraping the tea foam in the tea art performance is only out of psychological habits. After knowing the truth about tea foam, there is no need to have these worries.
