Tii nhema, iyo yakaviriswa zvizere, ndiyo tii inodyiwa zvakanyanya pasi rose. Ichiri kugadziridzwa, inofanirwa kusvava, kukunguruka uye kuviriswa, izvo zvinokonzeresa maitiro akaomarara ebiochemical yezvinhu zviri mumashizha etii uye pakupedzisira inobereka kunhuhwirira kwayo uye hutano. Munguva ichangopfuura, boka rekutsvakurudza rinotungamirirwa naProf WANG Yuefei kubva kuKoreji yekurima uye Biotechnology, Zhejiang University, yakaita nhevedzano yekufambira mberi maererano nekugadzirwa kwehutano uye hutano hwehutano hwe black tea.

Nekushandisa ongororo yekunzwa uye metabolomics kuongorora mhedzisiro yeakasiyana ekugadzirisa maparamendi pane inoshanduka uye isiri-inotenderera makomisheni eZijuan dema tii, timu yakaona kuti phenylacetic acid uye glutamine zvakabatana zvakanyanya nekunhuhwirira uye kuravira kweZijuan nhema tii, zvichiteerana, nekudaro ichipa chirevo chekugadzirisa nzira yekugadzira yeZijuan dema tii (Zhao et al., LWT -Sayenzi Yezvokudya uye Tekinoroji, 2020). Mune zvidzidzo zvakatevera, vakaona kuti kuwedzera kweokisijeni kunogona kukurudzira makatechini, flavonoid glycosides uye phenolic acids, uye catechins oxidation inogona kukurumidza kuparara kweamino acids kuti igadzire aldehydes inoputika uye inosimudzira kusvibiswa kwe phenolic acids, nokudaro kuderedza astringency uye kusuruvara uye kuwedzera umami. , iyo inopa ruzivo rutsva mukukodzera kuumbwa kweblack tii. Izvi zvakawanikwa zvekutsvaga zvakaburitswa muchinyorwa chakanzi "Oxygen-enriched fermentation inovandudza kuravira kweblack tea nekudzikisa anovava uye astringent metabolites" mujenari.Food Research Internationalmuna Chikunguru, 2021.

Shanduko mune nonvolatile metabolites panguva yekugadziriswa inokanganisa ese emhando uye inogona kuita hutano basa reblack tii. Muna Mbudzi 2021, timu yakaburitsa chinyorwa chekuvhura-yakavhurika chakanzi "Nonvolatile metabolite alterations panguva yeZijuan black tea processing inokanganisa simba rekudzivirira paHOECs rakafumurwa nicotine" mujenari.Chikafu & Basa. Chidzidzo ichi chakaratidza kuti leucine, isoleucine, uye tyrosine ndiyo yaive yakanyanya hydrolysis zvigadzirwa panguva yekusvava, uye theaflavin-3-gallate (TF-3-G), theaflavin-3'-gallate (TF-3'-G) uye theaflavin-3 , 3'-gallate (TFDG) yakanyanya kuumbwa panguva yekukunguruka. Uyezve, oxidation yeflavonoid glycosides, makatechini uye dimeric catechins yakaitika panguva yekuvirisa. Munguva yekuomesa, kutendeuka kweamino acid kwakava kukuru. Shanduko dze theaflavins, mamwe maamino acids uye flavonoid glycosides dzakave nemhedzisiro yakakura pakupokana kweZijuan dema tii kune nicotine-induced yemunhu mumuromo epithelial cell kukuvara, zvichiratidza kuti kupfumisa kweanoshanda zvinosanganisa uye kukwidziridzwa kweakakosha mabasa eblack tii nekuvandudza. iyo nzira yekugadzira yeblack tii inogona kunge iri zano rakangwara rekugadzira chigadzirwa chetii.

Muna Zvita 2021, timu yakaburitsa chimwe chinyorwa chine musoro unoti "Black Tea Alleviates Particulate Matter-Induced Lung Injury via Gut-Lung Axis in Mice"Journal ofAgricultural and Food Chemistry. Ongororo iyi yakaratidza kuti PM (chedu chinhu) -makonzo akafumurwa airatidza kushushikana kweoxidative uye kuzvimba mumapapu, izvo zvinogona kudzikiswa zvakanyanya nekudyiwa kwemazuva ese kweZijuan dema tii infusion nenzira inotsamira. Sezvineiwo, ese ethanol-soluble chikamu (ES) uye ethanol precipitate chikamu (EP) yakaratidza zvirinani mhedzisiro pane yeTI. Uyezve, fecal microbiota transplantation (FMT) yakaratidza kuti gut microbiota yakagadziridzwa zvakasiyana neTI uye zvikamu zvayo zvakakwanisa kubvisa zvakananga kukuvara kwakakonzerwa nePMs. Mukuwedzera, iyoLachnospiraceae_NK4A136_groupinogona kunge iri yakakosha gut microbe inobatsira mukuchengetedzwa kweEP. "Izvi zvigumisiro zvakaratidza kuti kunwa kwezuva nezuva kweti nhema uye zvikamu zvayo, kunyanya EP, zvinogona kuderedza kukuvara kwemapapu kunokonzerwa nePM kuburikidza ne-gut-lung axis mumakonzo, saka zvichipa zvinyorwa zvehutano hwehutano hweti yeti," akadaro Wang.
