Let me give you a brief squeeze, the most important class of substances in tea is called tea polyphenols, how much can tea polyphenols account for? Before we just brewed this tea, this is called dry tea, and the proportion of tea polyphenols in dry tea is probably the highest accounting for 36.9%, that is, it is the most important class of substances in tea.
Dry tea
1. Natural antioxidants: catechins in tea polyphenols
But what are tea polyphenols? Tea polyphenols are a class of substances, it is not a single, tea polyphenols contain the most important substance called catechins. Why does drinking tea make us young? Because catechins are natural antioxidants, it can scavenge our free radicals.
It is a scientific concept of human aging, why do people age? It is more and more free radicals, which cause our oxidation, that is, people will always have that kind of age spots, that is, the scavenging of free radicals is getting slower and slower, and catechins are natural antioxidants.
Age spots
Then catechins can account for about 75% of the total content of tea polyphenols, which is what we call antioxidants, which actually confirms why drinking tea can make people younger. This is the main class of substances. When we absorb it, nature can be young.
2, the age of the tea will be hungry after drinking: ester catechins are at work
Catechins are then subdivided into ester catechins and simple catechins. Ester catechins are the highest in tea plants such as this small tree, for example, but it is characterized by strong irritation, and now it is complicated, and now it is complicated into English letters;
Tea trees that are small in age
This type of substance actually accounts for the highest proportion of catechins. So why is it said that Taiwan tea or the tea made of tea that is not very old, you will feel hungry after drinking, you will feel that the stomach is very weak, and the ability to consume food is strong, because of the irritation.
Ability to consume food
3, drink more comfortable ancient tree tea: simple catechin content is high
The other is simple catechins, simple catechins are less irritating, but the content of simple catechins, that is, the older the tree, the higher the content of simple catechins.
Ancient tea trees with higher simple catechin content
So that's why, the so-called ancient tree tea we say, or you say, for example, like the old fir in other teas, you drink relatively little stimulation to the stomach, this is the scientific truth.
Large-leaf tea with a large tree age
4, say that white tea makes women young reasons: higher flavonoid content
Then you look at the tea polyphenols, catechins are the most important category of it, it accounts for 75%, the other 25% what? Anthocyanins.
What's in anthocyanin? Flavonoids, flavonol, you go to the place where white tea is sold, he must tell you, why can I make you women very young? Our white tea has a high content of flavonoids and is also an antioxidant, which is actually much worse than catechins, right?
Pick white tea
Summary: The Importance of Tea Science
Therefore, tea gives our body a lot of benefits, basically because of tea polyphenols, understand? Don't be so complicated, everything is now starting to give you English letters, my God, there is no need, you scare people for half a day, you are not good for promotion.
In fact, the most meaningful development of this industry is that consumers are becoming more and more aware, and consumers are really liking it by understanding that this is benign, right?
The consumption end is ok, in order to force the production end of the rules to go, you say this is right? Consumers are all confused, the production end I want to come how to come, all to you is ancient tree tea, all to you is the old ban zhang.
So, this is what I told you, that is, the importance of tea science class, it must be learned, because you understand this truth, all your tea leaves, as long as it is tea, it must still have tea polyphenols, since it has, it is just how much.
