Li Shizhen, a great medical scientist, once said: There are few real teas and more miscellaneous teas, which are also infested.
Especially in modern times, when black-hearted merchants can put various additives in inferior tea to make it shoddy, how should we identify these garbage to prevent ourselves from being harmed?
Pigmented tea
In the processing of green tea, "killing green" is a very important process, in which "green" refers to the polyphenol oxidase in tea. If it is "killed", the tea will not be oxidized and can remain green for a long time.
Killing green tea has a great influence on the quality of tea, such as "Daguan Tea Theory": the beauty and evil of tea, especially in steaming buds (a method of killing green), and the gain and loss of pressing yellow.
Due to problems such as the production process or the poor raw materials, some tea leaves are very ugly after they are finished, and they will naturally become uglier when they are oxidized in the future.
Among these pigments, the most common is lead chrome green, which is a kind of paint, which can cause great damage to the central nervous system and organs of people, which is very annoying.
Identification:
1. Green tea vellus is often white, and dyed green tea vellus is green.
2. Wet the white napkin with tea water. If there are obvious color blocks, it is likely to be mixed with chemical dyes.
Fried tea with sugar
The so-called sweetness, that is, the sweet aftertaste, is one of the most fascinating properties of tea.
As Wang nephew of the Qing Dynasty praised: the seal pattern is natural, and the tea taste is sweet and fragrant.
In order to achieve the effect of "returning the sweetness" of inferior products, black-hearted merchants often add sugar directly to the fried tea. Although the pit is a bit of a pit, at least it is not harmful to the human body. If you really drink it, you should drink it.
normal tea
Identification:
1. Gently twist with hands, sticky hands, or there is a crisp shell on the surface of the tea, it is likely to be fried tea with sugar.
2. If you lick it, you can obviously taste the sweetness, which is also fried with sugar.
3. The sugar added during the frying process is only attached to the surface of the tea leaves, so the sweetness of the first brew is very obvious, but the sweetness of the second brew dissipates, and the drop will be very large, which can also be distinguished based on this.
Talc Tea
Talc is a magnesium silicate mineral, and its powder treated with hydrochloric acid is talc powder. The World Health Organization defines it as a carcinogen. It is slightly pitted, but it is much less harmful than No. 1 paint.
Black-hearted merchants often use talcum powder to cover the darkened bottom of inferior tea leaves, making them look better, taste fresher and heavier.
During the Guangxu period, an official from a tea area wrote an official document commenting that: when making tea, adding talc powder, etc., makes it dark and dark... In addition to the indigo color, talc, white wax and other powders are added, and they are made into a brown luster. Benefit to win.
Identification:
After adding talcum powder, the tea soup will be abnormally cloudy, which is very abnormal. This kind of counterfeiting method is relatively low-end and generally exists in small workshops that are shoddy.
Essence tea
Regarding the aroma of tea, Song Huizong said that (inferior tea) "if the peach kernel is mixed, its gas is sour and evil", which forms a dazzling contrast with good tea.
Therefore, black-hearted merchants choose to add flavor to tea to deceive consumers with shoddy products.
Identification:
1. Essence tea has a strong fragrance and is extremely unnatural.
2. Normal tea can only be brewed with fragrance above 80 ℃. Tea with warm water is very fragrant. Eighty percent of it is essence tea.
3. Essence tea has a low durability. Generally, after brewing, the aroma of each brewed tea decreases quickly.
