Black tea fungus beverage tastes slightly sour, and it is a live fungus beverage like yogurt. The thallus of Kombucha is considered as the organism of yeast, lactic acid bacteria and acetic acid bacteria.
nutritive value
The black tea fungus liquid contains tea, sugar, lactic acid, acetic acid, yeast amino acids, vitamins, lecithin, coenzyme A, minerals, carbon dioxide and about 20 natural nutrients. Sweet and sour, cool and antipyretic, with unique flavor. Compared with other acidic drinks, it is more nutritious, has more health care and medical effects, has less side effects and has higher social and economic benefits. Known as the "king of drinks" by experts, it is a rare nutritional and health care treasure in the world.
Black tea fungus is rich in lactic acid bacteria, yeast, acetic acid bacteria, tea pigment, theophylline and tea polyphenols, so it has five functions of nutrition, prevention, health care, medical treatment and rehabilitation. It can prevent and treat 28 kinds of acute and chronic diseases such as cancer, cardiovascular and cerebrovascular diseases, stomach, liver and kidney, so its curative effect is outstanding, which is superior to the current microbial preparations.
Black tea fungus liquid is rich in more than 30 kinds of nutrients beneficial to human body, such as lactic acid bacteria, yeast, acetic acid bacteria, organic acids, sugars, vitamin B, C amino acids, including a large number of microbial active bacteria beneficial to human body, such as yeast, acetic acid bacteria, lactic acid bacteria, vitamin C, vitamin B and other nutrients, with 9.92 million yeasts per mg; Vitamin E has10-30mg per ml. Many active bacteria metabolize various vitamins, protein, ribose, nucleic acid, glutathione and other digestive enzymes and high-energy mixtures, among which calcium, magnesium, potassium, sodium, phosphorus and other minerals are essential to human body. Therefore, black tea fungus can regulate the physiological function of human body, promote metabolism, preserve health and strengthen the body.
Health function
In recent years, the practice of applying black tea fungus in medical circles at home and abroad shows that black tea fungus can treat and protect a variety of chronic diseases, such as cleaning the stomach, dredging the stool, regulating blood pressure and reducing blood fat; Arteriosclerosis slowed down, heart disease improved, renal function recovered and liver disease disappeared; The gallbladder and kidney calculi become smaller, the phlegm and cough become lighter, the insomniacs sleep peacefully, and the menopausal function is blocked and reduced.
Black tea fungus has strong antibacterial ability, fast fermentation and high acidification degree. Due to the comprehensive reaction of black tea fungus itself, many substances beneficial to human health are produced, such as yeast, acetic acid bacteria, lactic acid bacteria and other microorganisms. Yeast cells contain a lot of amino acids and digestive proteins, and yeast is often used to directly produce protein in industry. In addition, yeast glucose, inorganic salts, VB and VE contained in yeast have strong nutritional effects on human body. In particular, the cell wall of yeast can produce a substance called "B Guluqian", which is recognized as an anticancer substance in the world today. Acetobacter can absorb the alcohol decomposed by yeast, secrete acetic enzyme, oxidize alcohol into acetic acid and water, and release heat at the same time, so that the nutrition in human body can be fully utilized and metabolism can be promoted. The existence of lactic acid bacteria destroys the growth environment of bacteria, and the growth of bacteria is inhibited until death in the presence of acid. Therefore, black tea fungus can really enhance the human body's ability to resist viruses, and play a role in preventing and treating diseases and prolonging life.
China people regard black tea fungus as a "magic tea" that can cure all diseases: after drinking black tea fungus, the blood pressure of some hypertensive patients can remain stable; Some patients with atrophic gastritis have improved significantly; Some patients have constipation after drinking; More people feel energetic, tired, moist and disease-resistant after drinking. Kombucha has made gratifying achievements in the prevention and health care of cancer, cardiovascular and cerebrovascular diseases, liver and kidney diseases, obesity, alopecia areata and other diseases. Russian microbiologist Mechnikov called it "the immortal drink".
Culture of black tea fungus
Black tea fungus is brewed from black tea (or green tea, oolong tea, kudingcha, scented tea, etc.). ), white sugar (or rock sugar, honey) and water. The ratio of raw materials for cultivating black tea fungus is black tea: sugar: water = 0.2: 20: 200.
1. Culture of mother liquor: First, add a little black tea and sugar into boiling water in proportion to make it into diluted black tea syrup, then cook it for sterilization, and then put it into a sterilized glass. When cooling to 35℃, add a piece of finger-sized black tea fungus and seal the cup mouth with clean gauze. After three or four days (depending on the ambient temperature at that time, etc. ), the bottom of the cup will grow green cilia, and the liquid level will grow out to sea.
2. Culture of drinking liquid: in a sterilized beaker, add boiled black tea syrup, and then add mother liquor. It will ferment into sweet and sour tea in a week or so, and it can be drunk. After drinking the tea liquid, the remaining fungus mothers can continue to cultivate the tea liquid as above, and so on.
3. Strain culture: Strain culture is carried out on the basis of culture mother liquor. There are many layers of bacteria in the mother liquor, and the lower layer is tender and fresh, which is suitable for bacteria. A good mother will float on the liquid surface, showing milky white translucent colloidal colonies, and the culture medium smells sweet and sour. If the flora is red and green, it will be infected; The culture medium is not drinkable.
Drinking method
(1) In order to keep the activity of yeast and lactic acid bacteria in the bacterial liquid, the cultured bacterial liquid should be drunk with it.
(2) In order to avoid the bacteria liquid being too acidic and irritating the stomach, cold boiled water can be used to dilute the bacteria liquid, but frozen water is not suitable.
(3) Each person can drink several times a day. When drinking, add 2 times of cold boiled water to adjust the release, so that the bacterial liquid is sweet and sour.
