ʻO ke kī ʻeleʻele, ka mea i hoʻomoʻa piha ʻia, ʻo ia ka ti i hoʻopau ʻia ma ka honua. ʻOiai ke kaʻina ʻia, pono ia e maloʻo, ʻōwili a me ka fermentation, kahi e hoʻoulu ai i nā hopena biochemical paʻakikī o nā mea i loko o nā lau kī a hānau ʻia i kona ʻono kūʻokoʻa a me ka hopena olakino. I kēia mau lā, ua hana ka hui noiʻi i alakaʻi ʻia e Prof. WANG Yuefei mai ke Kulanui o Agriculture a me Biotechnology, Zhejiang University, i kahi ʻano holomua e pili ana i ka hoʻokumu ʻana i ka maikaʻi a me ka hana olakino o ke kī ʻeleʻele.

Ma ka hoʻohana ʻana i ka loiloi sensory a me ka metabolomics e nānā i nā hopena o nā ʻāpana kaʻina hana like ʻole i nā pūhui volatile a me ka non-volatile o ka Zijuan black tia, ua ʻike ka hui ua pili nui ka phenylacetic acid a me ka glutamine i ka ʻala a me ka ʻono o ke kī ʻeleʻele Zijuan, kēlā me kēia. no laila e hāʻawi ana i kahi kuhikuhi no ka optimization o ka ʻenehana hana o Zijuan black tia (Zhao et al., LWT -ʻEpekema Meaʻai a me ʻenehana, 2020). Ma nā haʻawina hope aʻe, ua ʻike lākou he hiki i ka oxygen concentrations ke hoʻoikaika i ka catechins, flavonoid glycosides a me phenolic acids, a hiki i ka catechins oxidation ke hoʻolalelale i ka hoʻohaʻahaʻa ʻana o nā waikawa amino e hana ai i nā aldehydes volatile a hoʻoikaika i ka hoʻohemo ʻana o nā waikawa phenolic. , e hāʻawi ana i kahi ʻike hou i ka hoʻokumu kūpono ʻana o ke kī ʻeleʻele. Ua paʻi ʻia kēia mau ʻike noiʻi ma kahi ʻatikala i kapa ʻia ʻo "Oxygen-enriched fermentation e hoʻomaikaʻi i ka ʻono o ke kī ʻeleʻele ma o ka hōʻemi ʻana i ka ʻawaʻawa a me nā metabolites astringent" ma ka puke pai.ʻImi ʻAi Meaʻaii Iulai, 2021.

Hoʻololi nā hoʻololi i nā metabolites nonvolatile i ka wā o ka hana ʻana i ka maikaʻi a me ka hana olakino olakino o ke kī ʻeleʻele. I Nowemapa 2021, ua paʻi ka hui i kahi ʻatikala wehe ʻia i kapa ʻia ʻo "Nonvolatile metabolite alterations i ka wā o Zijuan black tea processing e pili ana i ka hiki ke pale i nā HOEC i hōʻike ʻia i ka nicotine" ma ka puke pai.Meaʻai & Hana. Ua hōʻike ʻia kēia haʻawina ʻo ka leucine, isoleucine, a me tyrosine nā huahana hydrolysis nui i ka wā maloʻo, a me theaflavin-3-gallate (TF-3-G), theaflavin-3'-gallate (TF-3'-G) a me theaflavin-3 ,3'-gallate (TFDG) i hoʻokumu nui ʻia i ka wā o ka ʻōwili ʻana. Eia kekahi, ʻo ka oxidation o flavonoids glycosides, catechins a me dimeric catechins i loaʻa i ka wā fermentation. I ka wā maloʻo, lilo ka hoʻololi ʻana o ka amino acid i mea nui. ʻO nā hoʻololi o theaflavins, kekahi mau amino acids a me flavonoids glycosides he hopena koʻikoʻi i ke kūʻē ʻana o Zijuan black tia i ka nicotine-induced human oral epithelial cell injury, e hōʻike ana i ka hoʻonui ʻana i nā mea hana kūikawā a me ka hoʻonui ʻana i nā hana kūikawā o ke kī ʻeleʻele ma o ka hoʻomaikaʻi ʻana. ʻO ke kaʻina hana o ke kī ʻeleʻele paha he manaʻo noʻonoʻo no ka hana ʻana i nā huahana kī.

I Dekemaba 2021, ua paʻi ka hui i kahi ʻatikala ʻē aʻe i kapa ʻia ʻo "Black Tea Alleviates Particulate Matter-Induced Lung Injury via the Gut-Lung Axis in Mice" ma kaMoolelo oMahiai a me ka meaʻai kemika. Ua hōʻike kēia haʻawina i nā ʻiole PM (particulate matter) i hōʻike ʻia i ke koʻikoʻi oxidative a me ka mumū i loko o ka māmā, hiki ke hoʻohaʻahaʻa nui ʻia e ka ʻai ʻana i kēlā me kēia lā o Zijuan black tea infusion ma kahi ʻano hilinaʻi. ʻO ka mea hoihoi, ʻoi aku ka maikaʻi o ka hakina ethanol-soluble (ES) a me ka hakina ethanol precipitate fraction (EP) ma mua o ko TI. Eia kekahi, ua hōʻike ʻia ka fecal microbiota transplantation (FMT) ua hoʻololi hou ʻia ka microbiota gut e TI a ua hiki i kāna mau hakina ke hoʻopau pololei i ka ʻeha i hoʻokomo ʻia e PM. Eia hou, kaLachnospiraceae_NK4A136_huiʻO ia paha ka microbe gut core e hāʻawi i ka pale o EP. "Ua hōʻike kēia mau hopena i ka ʻai ʻana i kēlā me kēia lā o ke kī ʻeleʻele a me kāna mau hapa, ʻoi aku ka EP, hiki ke hōʻoluʻolu i nā hōʻeha ʻeha o ka PM-induced ma o ka axis gut-lung i nā ʻiole, no laila e hāʻawi ana i nā kuhikuhi no ka hana olakino o ke kī ʻeleʻele," wahi a Wang.
