Discriminate quality Anxi tieguanyin tea by DNA
People are used to ask “is it authentic Anxi tieguanyin tea” when they’re purchasing tea while the answers of sellers are uniformly “yes”. According to person in the know, tieguanyin tea on the market is mostly being titled by Anxi tieguanyin tea, but there’s no lack of fake. Now, people can discriminate if the tea is authentic Anxi tieguanyin tea by DNA.
Just as the name implies, Anxi tie guan yin tea is oolong tea originating from Anxi while its finished tea has unique features like natural fragrance, obvious “Kwan-yin flavor” and strong aftertaste. According to materials on Anxi tea association website, the geographical trade market “Anxi” of tieguanyin tea applies to producing areas within Anxi borders as Xiping, Huqiu, Daping, Lutian, Longjuan, Xianghua, Changkeng, Lantian, Gande, Jiandou, Hushang, Jingu, Fengcheng, Chengxiang and Guanqiao.
People in the industry introduce that in recent years, tieguanyin tea largely produced in Yongchun, Nanan, Huaan, Zhangping and Sanming of Fujian hasn’t been marked with original place but been titled with “Anxi tieguanyin”. In the past few days, some news disclosed that it also happened in Liping of Guizhou.
The development of this item will greatly increase purity quotient of tieguanyin tea so as to keep its excellent quality as well as strengthen Anxi tie guan yin tea’s competitiveness at home and abroad, said the board chairman of Flying Tea Industry.
To discriminate if the so-called Anxi tieguanyin tea on the market was produced in Anxi, we may use the fingerprint technology, said professor Sun Weijiang, tutor of a Ph.D. student as well as dean of Tea Science Department of Fujian University of Agriculture and Forestry. He introduced that the DNA fingerprint may discriminate the tieguanyin tea whether produced in Anxi or areas apart from Anxi. It can even discriminate tieguanyin tea produced in the professional calling “internal Anxi” and “external Anxi”. With the establishment and improvement of fingerprint technology, the DNA fingerprint may find which manufacturer was the Anxi tieguanyin produced in so that consumers may get the information fully at on glance.
