Tea cream efficacy
1, the effect of relieving alcoholism and protecting liver
The hangover relieving function of Pu 'er tea has been recognized for a long time in the industry. Not only that, among many hangover products, Pu 'er tea is not only a leader, but also a special product in Pu 'er tea-Pu 'er tea paste, which has always enjoyed the reputation of "the first product to sober up" since ancient times.
The catabolism of alcohol in human body mainly depends on two enzymes: one is alcohol dehydrogenase and the other is acetaldehyde dehydrogenase. Alcohol dehydrogenase can remove two hydrogen atoms from alcohol molecules and decompose ethanol into acetaldehyde. On the other hand, acetaldehyde dehydrogenase can remove two hydrogen atoms from acetaldehyde, thus converting acetaldehyde into acetic acid and finally decomposing it into carbon dioxide and water.
At the same time, L- alanine contained in Pu 'er tea paste will produce a large amount of pantothenic acid in human body and promote normal alcohol metabolism. In addition, L- cysteine can react with alcohol, accelerate alcohol metabolism, absorb a certain amount of alcohol, and improve human tolerance to alcohol. It can be converted into cystine, and taurine can repair damaged liver cells, brain cells, gastric mucosa and tissues. So in this sense, the process of hangover is also a process of protecting the liver.
2, digestion, greasy effect
Anyone who has tasted Pu 'er tea paste knows that drinking Pu 'er tea paste after eating beef and mutton or eating big fish and meat is extremely fast. There used to be a misunderstanding that Pu 'er tea paste can help digestion and relieve cattle annoyance because caffeine contained in Pu 'er tea paste stimulates gastrointestinal peristalsis, thus achieving the effect of rapid digestion. But this is not the real reason. Scientists once did an experiment: put a few pieces of meat in a wire cage for an eagle to eat. After a while, take it out of the cage and the pieces of meat disappeared. Therefore, the previous statement that gastrointestinal peristalsis helps digestion was shaken. It is recognized that there are some substances in gastric juice that can digest meat. Among them are pepsin, glucoamylase and so on. This experiment also indirectly denied the theory that Pu 'er tea cream contains caffeine to stimulate gastrointestinal peristalsis and help digestion.
In the subsequent fermentation process of Pu 'er tea paste, its inherent cellulase and pectinase are decomposed into a large number of derivatives under the interaction of other enzyme systems. These derivatives not only contain glucoamylase, but also contain other enzymes that react with the biological enzyme system of human gastrointestinal tract, which can increase the secretion of pepsin, promote the improvement of pepsin activity, strengthen the digestion ability of the stomach for protein food, and enhance the digestion function of human body.
3, the effect of nourishing the stomach
One of the most remarkable features of Pu 'er tea paste is that it can be drunk on an empty stomach, that is, it does not harm people's gastrointestinal tract and has the effect of nourishing the stomach. There are three reasons:
First, after fermentation-extraction-fermentation-membrane filtration, Pu 'er tea paste is basically small molecules, which is beneficial to human gastrointestinal absorption and has little irritation. Green tea is different from oolong tea. The "cold" of green tea in Chinese medicine is probably related to the macromolecules it contains. Similarly, Pu 'er tea without artificial fermentation and natural fermentation (commonly known as raw Pu 'er tea) cannot be drunk on an empty stomach because its molecular weight is too large.
Second, the pectin contained in Pu 'er tea paste is much higher than other teas. It not only embodies good adsorption, but also combines and eliminates bacterial toxins and other harmful substances in the body, such as lead, mercury and radioactive elements in heavy metals, and plays a detoxification role; At the same time, it can protect gastric mucosa and help digestion For people with gastric ulcer or gastritis, the pectin in Pu 'er tea can form a film, which can be attached to the wound of the stomach to promote the healing of the ulcer surface, and is suitable for patients with gastric diseases.
Thirdly, caffeine contained in Pu 'er tea paste can neutralize gastric acid in human body, thus improving digestive function.
The key point of the stomach-nourishing effect of Pu 'er tea paste lies in the fermentation quality. We can do an experiment: brew three kinds of tea samples: green tea, Pu 'er tea (three-year-old tea) and Pu 'er tea paste, and then put three cups of tea soup in the refrigerator. When the temperature of the tea soup drops to about 5 degrees above zero, take it out and observe whether the tea soup changes. At this time, we will find that the tea soup of green tea has a lot of milky suspended solids, which is the most turbid; Followed by Pu 'er tea, containing a small amount of milky suspended matter, the tea soup is brown, dark and opaque; The best one should be Pu 'er tea paste, without visible suspended matter and impurities. The color of tea soup is slightly darker than when it was just brewed. This experiment tells us that unfermented tea contains a lot of macromolecular substances. After the temperature of its tea soup drops, it leads to the chemical reaction of material reduction and polymerization, resulting in serious turbidity or slight turbidity, which is due to the insufficient fermentation process and the incomplete degradation of many substances. Pu 'er tea paste is the product of deep processing of Pu 'er tea, almost all of which are small molecules. Although there are also reduction and polymerization, the result is the polymerization of small molecules, but the tea soup is black.
