The entity of black tea fungus is mainly composed of yeast, acetic acid bacteria and lactic acid bacteria, which are beneficial to human body. They complement each other and metabolize in the state of "* * *", dissolving the metabolites into the culture solution. The polymer of microorganisms (i.e. bacterial membrane) floats on the surface of liquid, showing milky white, and the mother body is yellowish brown or reddish brown, floating under the membrane or in bacterial liquid. Due to different living habits, the distribution and functions of these three bacteria are also different.
Yeast is an oval unicellular fungus, which can breathe anaerobically in an anoxic environment and ferment sugars into alcohol, carbon dioxide and energy. So most of them are distributed in the lower part of the black tea fungus entity. Many compounds with nutritional value to human body in the liquid of black tea fungus are in yeast cells, and its nitride content (including protein and alkaline acid) is 2 times higher than that of meat, 4 times higher than that of eggs and 0/5 times higher than that of fresh milk. Its vitamin B content is also much higher than that of beans, wheat, peanuts and tomatoes. The cell wall membrane of yeast can produce a biological cell body called "B Gulugan", which is said to have anti-cancer effect.
Acetobacter is the main microorganism in black tea fungus, which is rod-shaped and flagellated and belongs to aerobic bacteria. It absorbs alcohol decomposed by yeast and oxygen in the air, and oxidizes it into acetic acid, water and energy, which makes the bacterial liquid strongly acidic, so it is a good bactericide and can inhibit the reproduction and growth of other harmful bacteria. It is mainly distributed in the upper layer of black tea fungus. Drinking bacterial liquid containing acetic acid bacteria can help digestion of the stomach, enhance absorption capacity and reduce blood lipid.
Lactic bacteria, including Lactobacillus bulgaricus and Lactobacillus acidophilus, belong to anaerobic bacteria. It can secrete lactase, hydrolyze lactose into glucose and galactose, and then ferment into lactic acid and gluconic acid. The glucose produced can be used for yeast fermentation. Lactic acid bacteria have strong acid resistance, and most of them exist in the lower part of bacteria and coexist with yeast. Lactic acid bacteria can inhibit the proliferation of intestinal spoilage bacteria, prevent and hinder the decomposition of harmful bacteria to produce toxic substances, and at the same time, they can also synthesize vitamins B 1, B6, B 12, K, E, creatine, folic acid and other substances needed by human body. These microorganisms have a strong ability to synthesize nutrients, and the nutrients synthesized every day and night are 30 to 40 times their own weight, which is beyond the reach of ordinary animals and plants.
The medium needed by microorganisms such as yeast, acetic acid bacteria and lactic acid bacteria is made of tea juice and sugar. Sugar is an indispensable nutrient in people's daily life and an energy source for life activities, while tea juice contains more extensive nutrients. Such as tea polyphenols, protein, amino acids, sugars and caffeine, and also contains many mineral elements such as manganese, tungsten, potassium and copper, which also have certain physiological effects on human body. If tea juice and sugar are continuously supplemented in the culture medium, yeast, acetic acid bacteria and lactic acid bacteria can not only survive in it, but also reproduce and develop, producing more metabolites for people to use.
According to the research, the liquid of black tea fungus contains more than 30 kinds of nutrients, especially organic acids (including lactic acid, acetic acid, folic acid, etc. ), sugars (including glucose, fructose, sucrose, galactose, etc. ), vitamins (especially C and B groups), amino acids, lecithin, coenzyme A and carbon dioxide will all increase greatly. Individually, the content of these substances is not high. But in general, it is nutritious and has the function of nourishing and strengthening the body. Many drinkers will feel that their appetite is increased, their defecation is smooth, their immunity is enhanced, and some diseases are controlled or even cured.
Black tea fungus is a traditional and healthy family brewed beverage, which is convenient to produce and delicious to drink.
Raw material container
Tea: Black tea, green tea, oolong tea, scented tea and other teas are all acceptable, but tea ash and moldy tea are not suitable.
Sugar: rock sugar, white sugar, glucose and honey are all acceptable, but brown sugar (or earth sugar) and sugar residue cannot be used.
Water: It is best to use clean water such as cold boiled water, pure water and spring water.
Fungal mother membrane: it is best to be fresh, pure and healthy, milky white and yellowish.
Container: Use two washed jars and boil them for disinfection.
manufacturing method
1. Tea and sugar water equipment
Tea, sugar and water? 1: 10: 100 put in a teapot and cook 10 minutes;
You can also put 5g tea leaves and a spoonful of sugar into a teacup and pour boiling water. When the tea syrup is cooled to 20℃-30℃, the tea syrup is filtered, and the pure filtrate is poured into a sterilized jar (the filtrate is two-thirds of the volume of the jar).
2. Inoculate black tea fungus
Inoculate the selected mother film, pour the mother liquid, and then wrap the bottle mouth with gauze. When inoculating bacterial membrane, pay attention to cleanliness and hygiene, and don't be contaminated with miscellaneous bacteria. Keep the bottle away from sunlight and put it in a stable place for about 10 days (high temperature, short time; Low temperature, long time), the bacterial membrane increases rapidly and fills the liquid surface, the color of the culture solution becomes lighter, the solution becomes turbid, bubbles are generated, and the sweet and sour aroma is emitted, so it can be drunk at this time.
3. Post-treatment after curing
When drinking and taking food, you can gently pour the fungus liquid into the cup (about 2/3 ~ 3/4 of the culture liquid), and the fungus mother and the rest are still in the bottle, then prepare the tea soup according to the above method and slowly pour it into the bottle. The two jars can be cultivated and fed alternately, and the cycle is endless.
4. Drink black tea and mushroom soup
When drinking, you can adjust the acidity of the black tea fungus liquid according to your personal preference. If it is too sour, you can add sugar and cold boiled water or dilute it with tea soup. It is advisable to drink 100 ~ 200ml per person every day, which can be drunk once or several times. Because the bacterial liquid is acidic and the pH value is 2 ~ 4, it is not suitable to be taken with drugs, especially alkaline drugs. Some first-time drinkers will have some side effects after taking black tea fungus, such as insomnia, stomach acid, mild diarrhea and itchy skin. If you drink it for a long time, most of the symptoms will disappear by themselves. If you really can't adapt, you can only give up drinking.
Matters needing attention
When making black tea fungus, we should pay attention to the following aspects:
1. Choose a good mother to prevent mixed bacteria infection. In the event of mixed bacteria infection, you can't drink it;
2. When the fungus mother is aging, that is, when the fungus mother is reddish brown and brown, it should be re-inoculated and re-cultured;
3. Wash the culture vessels and utensils, and then put them in boiling water for 20 minutes for disinfection;
4. The utensils and appliances should be made of transparent lead-free glass or ceramic products with colorless glaze, and metal products cannot be used;
5. It is most suitable to culture the bacterial liquid at 25℃-30℃, but it is necessary to avoid sun exposure and shock absorption.
Black tea fungus has unique nutrition and health care functions.
1, prevention and treatment of gastropathy
Black tea fungus liquid has the effect of anti-Helicobacter pylori, and has a good therapeutic effect on atrophic gastritis and gastric ulcer.
Step 2 supplement probiotics
Due to the abuse of antibiotics, probiotics in the intestine are destroyed, resulting in decreased resistance and threatening health.
Lactic acid bacteria is an important flora with important physiological functions in human body. Lactic acid bacteria can inhibit abnormal fermentation in the intestine, prevent the human body from absorbing toxins produced by the decomposition of harmful bacteria, and make some substances in the intestine produce various vitamins, which is helpful to the health of the human intestine and prevents the human body from aging rapidly. The number of lactic acid bacteria in the intestine is an important indicator of human health. The number of lactic acid bacteria will gradually decrease with the increase of people's age, and the number of lactic acid bacteria in the intestine of the elderly may decrease to 10%.
Yeast is rich in protein and contains dozens of amino acids, eight of which are essential for human body. Yeast protein also has the function of anti-cancer and dissolving cancer cells. Yeast cells also contain a variety of vitamins, especially B vitamins.
Acetobacter is the main microorganism in black tea fungus. Acetic acid produced by Acetobacter has strong acidity, which can clear the intestine and stomach, help digestion, prevent constipation, improve the stability of vitamins, prevent the invasion of harmful bacteria and viruses, and prevent colds.
Black tea fungus liquid contains a large number of active lactic acid bacteria, acetic acid bacteria and yeast, which can regulate intestinal flora and promote human health.
3, enhance the liver detoxification function
Gluconic acid in black tea fungus has detoxification function, which can combine with phenolic substances (harmful carcinogens) in the body to form lipids and be excreted smoothly.
4. Relieve gout and kidney calculi.
Regulate the body's pH and relieve the symptoms of gout and kidney calculi.
5. Prevent cardiovascular and cerebrovascular diseases.
Black tea fungus liquid can reduce cholesterol, improve atherosclerosis, prevent cardiovascular and cerebrovascular diseases and delay aging.
6, improve immunity
Acetic acid in black tea fungus liquid can stimulate the production of accessory renal cortical hormone, which is the source of natural healing power of the body and an important substance to defend life. Therefore, drinking black tea and fungus liquid often can improve immunity and prevent colds.
Step 7 lose weight
The black tea fungus liquid brewed by black tea fungus and tea (or other teas such as green tea and scented tea) has many health care functions, contains a lot of probiotics and nutrients, and is a carbonated beverage with extremely low sugar content. Regular drinking can promote metabolism and avoid obesity.
