Dip tea with your fingers and pinch it. If it fades, it will prove to be dyed tea.
As the saying goes, "Ming before the tea, expensive as gold", the new tea listed during the Ching Ming Festival because of its taste mellow and cotton, coupled with a small amount of output, so it is particularly precious. However, at this time each year, some unscrupulous traders will take advantage of this opportunity to reprocess the tea and make up new tea. Recently, such "refurbished tea" has appeared in places like Shanghai, Nanchang, Hangzhou, Beijing and Zhengzhou. In this regard, Shen Hong, a national first-class tea maker and senior engineer of the National Tea Quality Supervision and Inspection Center, said in an interview with a reporter from the “Life Times†that Chen tea posing as a new tea needs to be stained with a dye, if it is dyed with lead-chromium green, It will endanger health.
Shen Hong said that each year after the new tea season, some shops will sell the remaining tea into cold storage, and wait until next year, use food coloring agents and cooking oil to fry the tea and pretend to be a new tea; or wait for the new tea to come on the market and mix it with new tea. Sold together. Although this kind of tea tastes slightly worse, it does not harm human health much. A few traders used industrial pigment lead-chromium green to dye Chen tea, processed it into a brand-new “new tea†and sprayed with flavor, which would undoubtedly cause harm to the human body.
Shen Hong reminds us that we must be vigilant for dyeing tea. For those green teas that are too bright, we should use a small amount on the palm of our hand. Use your fingers to pinch the cold water and pinch the tea leaves. If you leave green traces on your fingers, you can prove this. Kinds of tea stained. In addition, if the tea color is green and it is still aquamarine after being soaked for a few times, the tea is likely to be "dyed tea."
Finally, the following points need to be noted in the selection of new tea: In appearance, the shape of the new tea is more compact and the Chen tea is more divergent; the new tea is more vivid and lustrous than the tea, and the tea is often dark in color; the tea is soaked in boiling water. After the new tea was bright and the color of the tea was yellow and turbid; the new tea smelled fresh and fresh, while the tea did not have a good smell, and there was still a sense of anger. Especially for Longjing tea and Biluochun, the new teas have distinct characteristics. The former has yellow color in the green and some spots on the foliage; the latter has a young bud with a white hair on the back of the bud.
