incazelo emfushane:
Itiye elimhlophe livela kuI-Camellia sinensistshala njengetiye elimnyama, itiye eliluhlaza kanye netiye le-oolong. Ingenye yezinhlobo ezinhlanu zetiye ezibizwa ngokuthi amatiye eqiniso. Ngaphambi kokuba amaqabunga etiye elimhlophe avuleke, amahlumela avunwa ukuze kukhiqizwe itiye elimhlophe. Lezi zicucu zivame ukumbozwa izinwele ezimhlophe ezincane, ezinikeza igama lazo itiye. Itiye elimhlophe livunwa kakhulu esifundazweni saseFujian eChina, kodwa kukhona nabakhiqizi eSri Lanka, India, Nepal naseThailand.
I-oxidation
Amatiye eqiniso wonke avela emaqabunga esitshalo esisodwa, ngakho-ke umehluko phakathi kwetiye usekelwe ezintweni ezimbili: i-terroir (isifunda lapho isitshalo sikhula khona) kanye nenqubo yokukhiqiza.
Omunye umehluko enqubweni yokukhiqiza yetiye ngalinye leqiniso inani lesikhathi amaqabunga avunyelwe ukuba enze i-oxidize. Izingcweti zetiye zingagingqa, zichoboze, ziwose, zishise namahlamvu ngesitimu ukuze zisize enqubweni ye-oxidation.
Njengoba kushiwo, itiye elimhlophe licutshungulwa kancane kakhulu langempela futhi alingeni inqubo ende ye-oxidation. Ngokuphambene nenqubo ende ye-oxidation yetiye elimnyama, okuholela kumbala omnyama, ocebile, itiye elimhlophe livele libune futhi lome elangeni noma indawo elawulwayo ukuze kulondolozwe imvelo ehlanzekile engadini yemifino.
Iphrofayili ye-Flavour

Izinzuzo Zezempilo Zetiye Elimhlophe
1. Impilo Yesikhumba
Abantu abaningi bahlushwa ukungahambi kahle kwesikhumba njengezinduna, amabala nokushintsha kwebala. Nakuba eziningi zalezi zimo zesikhumba zingeyona ingozi noma zisongela ukuphila, zisacasula futhi zingehlisa ukuzethemba. Itiye elimhlophe lingakusiza ukuthi uzuze ibala elilinganayo ngenxa yezakhiwo ze-antiseptic ne-antioxidant.
Ucwaningo olwenziwa yiNyuvesi yaseKinsington eLondon lubonise ukuthi itiye elimhlophe lingavikela amangqamuzana esikhumba emonakalweni obangelwa i-hydrogen peroxide nezinye izici. Itiye elimhlophe elicebile nge-Antioxidant lisiza ekuqedeni ama-radicals mahhala angaholela ezimpawini zokuguga ngaphambi kwesikhathi okuhlanganisa umbala kanye nemibimbi. Izakhiwo zokulwa nokuvuvukala zetiye elimhlophe le-antioxidant nazo zingasiza ekwehliseni ububomvu nokuvuvukala okubangelwa izifo zesikhumba ezifana ne-eczema noma i-dandruff (1).
Njengoba induna ngokuvamile ibangelwa ukungcola nokwakheka kwama-radicals mahhala, ukuphuza inkomishi yetiye elimhlophe kanye noma kabili ngosuku kungasusa isikhumba. Kungenjalo, itiye elimhlophe lingasetshenziswa njengendlela yokuhlanza ukugeza ngqo esikhumbeni. Ungakwazi futhi ukubeka isikhwama setiye esimhlophe ngqo kunoma yiziphi izindawo eziyinkinga ukuze usheshise ukuphulukiswa.
Ucwaningo olwenziwa ngo-2005 olwenziwa nguPastore Formulations lubonise ukuthi itiye elimhlophe lingaba nenzuzo kubantu abahlushwa izimo zesikhumba ezihlanganisa i-rosacea ne-psoriasis. Lokhu kungaba nomthelela ku-epigallocatechin gallate ekhona etiyeni elimhlophe esiza ukukhiqiza amaseli amasha ku-epidermis (2).
Itiye elimhlophe liqukethe amanani aphezulu ama-phenols, angaqinisa kokubili i-collagen ne-elastin eboleka ukubukeka okubushelelezi, kobusha esikhumbeni. Lawa maprotheni amabili abalulekile ekudaleni isikhumba esiqinile futhi uvimbele imibimbi futhi angatholakala emikhiqizweni eyahlukene ye-skincare.
2. Ukuvimbela Umdlavuza
Ucwaningo lubonise ukuxhumana okuqinile phakathi kwetiye langempela kanye namandla okuvimbela noma ukwelapha umdlavuza. Nakuba izifundo zingaphelele, izinzuzo zezempilo zokuphuza itiye elimhlophe zibangelwa kakhulu ama-antioxidants nama-polyphenols etiyeni. Ama-Antioxidants etiyeni elimhlophe angasiza ekwakheni i-RNA futhi avimbele ukuguqulwa kwamangqamuzana ofuzo okuholela kumdlavuza.
Ucwaningo olwenziwa ngo-2010 lwathola ukuthi ama-antioxidants etiyeni elimhlophe ayesebenza kakhulu ekuvimbeleni umdlavuza kunetiye eliluhlaza. Abacwaningi basebenzise i-white tea extract ukukhomba amangqamuzana omdlavuza wamaphaphu elebhu futhi imiphumela yabonisa ukufa kweseli okuncike kumthamo. Ngenkathi izifundo zisaqhubeka, le miphumela ikhombisa ukuthi itiye elimhlophe lingasiza ukumisa ukwanda kwamangqamuzana omdlavuza futhi libe nomthelela ekufeni kwamaseli aguquliwe (3).
3. Ukuncipha Kwesisindo
Kubantu abaningi, ukuncipha kwesisindo kudlula nje ukwenza isinqumo sikaNcibijane; kuwumshikashika wangempela ukunciphisa amakhilogremu futhi uphile isikhathi eside futhi unempilo. Ukukhuluphala ngokweqile kungenye yezinto ezihamba phambili ekuphileni isikhathi esifushane futhi ukuncipha kwesisindo kuba seqhulwini ezintweni ezibalulekile kubantu.
Ukuphuza itiye elimhlophe kungakusiza ukuba ufinyelele imigomo yakho yokulahlekelwa isisindo ngokusiza umzimba wakho ukuba ubambe izakhi ngokuphumelelayo futhi uchithe amakhilogremu kalula ngokusheshisa i-metabolism. Ucwaningo lwaseJalimane lwango-2009 lwathola ukuthi itiye elimhlophe lingasiza ukushisa amafutha agciniwe emzimbeni ngenkathi livimbela ukwakheka kwamangqamuzana amafutha amasha. Ama-catechins atholakala etiyeni elimhlophe angasheshisa inqubo yokugaya futhi asize ngokuncipha kwesisindo (4).
4. Impilo Yezinwele
Akukhona nje ukuthi itiye elimhlophe lilungele isikhumba, lingasiza ekusunguleni izinwele ezinempilo. I-antioxidant ebizwa ngokuthi i-epigallocatechin gallate iye yaboniswa ukuthuthukisa ukukhula kwezinwele futhi ivimbele ukulahlekelwa izinwele ngaphambi kwesikhathi. I-EGCG iphinde yabonisa isithembiso lapho kwelapha izifo zesikhumba sekhanda ezibangelwa amagciwane amelana nokwelashwa okuvamile (5).
Itiye elimhlophe liphinde livikele ngokwemvelo emonakalweni welanga, elingasiza ekuvimbeleni izinwele ukuthi zome ezinyangeni zasehlobo. Itiye elimhlophe lingabuyisela ukukhanya kwemvelo kwezinwele futhi lisetshenziswa kangcono kakhulu njengeshampu uma ufuna ukugqama.
5. Ithuthukisa Ukuzola, Ukugxila kanye Nokuqapha
Itiye elimhlophe linenani eliphakeme kakhulu le-L-theanine phakathi kwetiye langempela. I-L-theanine yaziwa ngokuthuthukisa ukuqapha nokugxila ebuchosheni ngokuvimbela izisusa ezijabulisayo ezingaholela ekusebenzeni ngokweqile. Ngokuthulisa isisusa ebuchosheni, itiye elimhlophe lingakusiza uphumule ngenkathi futhi likhulisa ukugxila (6).
Le nhlanganisela yamakhemikhali nayo ibonise izinzuzo ezinhle zezempilo uma kuziwa ekukhathazekeni. I-L-theanine ikhuthaza ukukhiqizwa kwe-neurotransmitter GABA, enemiphumela yokupholisa yemvelo. Ingxenye engcono kakhulu mayelana nokuphuza itiye elimhlophe ukuthi ungathola izinzuzo zokuqapha okwengeziwe ngaphandle kwemiphumela emibi yokozela noma ukukhubazeka okuza nezidakamizwa zokukhathazeka.
Itiye elimhlophe liqukethe nenani elincane le-caffeine elingasiza ekuqaliseni usuku lwakho noma ukukunikeza i-pick-me-up ntambama. Ngokwesilinganiso, itiye elimhlophe liqukethe cishe u-28 mg we-caffeine kuyo yonke inkomishi engama-ounce angu-8. Lokho kungaphansi kakhulu kwesilinganiso esingu-98 mg enkomishini yekhofi futhi kungaphansi kuka-35 mg etiyeni eliluhlaza. Ngokuqukethwe kwe-caffeine ephansi, ungaphuza izinkomishi ezimbalwa zetiye elimhlophe ngosuku ngaphandle kwemiphumela engemihle ezingaba nayo izinkomishi eziqinile zekhofi. Ungaba nezinkomishi ezintathu noma ezine ngosuku futhi ungakhathazeki ngokuzizwa unesizungu noma ukuqwasha.
6. Impilo Yomlomo
Itiye elimhlophe linamazinga aphezulu e-flavonoid, ama-tannins nama-fluoride asiza amazinyo ukuthi ahlale enempilo futhi eqinile. I-fluoride yaziwa kakhulu njengethuluzi lokuvimbela ukubola kwamazinyo futhi ivame ukutholakala ezitsheni zokuxubha. Kokubili ama-tannins nama-flavonoid asiza ukuvimbela ukunqwabelana koqwembe olungadala ukubola kwamazinyo kanye nezimbobo (7).
Itiye elimhlophe libuye libe nezinto ezilwa namagciwane kanye ne-antibacterial esiza ukugcina amazinyo nezinsini kunempilo. Ukuze uthole izinzuzo zezempilo zamazinyo zetiye elimhlophe, hlose ukuphuza izinkomishi ezimbili kuya kwezine ngosuku uphinde ugibele izikhwama zetiye ukuze ukhiphe zonke izakhi kanye nama-antioxidants.
7. Siza Ukwelapha Isifo Sikashukela
Isifo sikashukela sibangelwa izakhi zofuzo nendlela yokuphila futhi siyinkinga ekhulayo ezweni lanamuhla. Ngenhlanhla, ziningi izindlela zokulawula nokulawula isifo sikashukela kanye netiye elimhlophe ingenye yazo.
Ama-catechin asetiyeni elimhlophe kanye namanye ama-antioxidants aboniswe ukusiza ukuvimbela noma ukulawula isifo sikashukela soHlobo 2. Itiye elimhlophe lisebenza ngempumelelo ukuvimbela umsebenzi we-enzyme amylase ekhombisa ukumuncwa kweglucose emathunjini amancane.
Kubantu abanesifo sikashukela soHlobo 2, le enzyme ihlukanisa isitashi sibe ushukela futhi ingaholela ekunyukeni kukashukela egazini. Ukuphuza itiye elimhlophe kungasiza ukulawula lezo spikes ngokuvimbela ukukhiqizwa kwe-amylase.
Ocwaningweni lwaseShayina lwango-2011, ososayensi bathola ukuthi ukusetshenziswa njalo kwetiye elimhlophe kwehlisa amazinga kashukela egazini ngamaphesenti angama-48 futhi kwenyusa ukukhiqizwa kwe-insulin. Ucwaningo luphinde lwaveza ukuthi ukuphuza itiye elimhlophe kusiza ekwehliseni i-polydipsia, okuwukoma okunzima okubangelwa izifo ezifana nesifo sikashukela (8).
8. Yehlisa Ukuvuvuka
Ama-catechin nama-polyphenols etiye elimhlophe aziqhenya ngezakhiwo zokulwa nokuvuvukala ezingasiza ekudambiseni izinhlungu ezincane nezinhlungu. Ucwaningo lwezilwane lwaseJapane olwanyatheliswa kuyi-MSSE Journal lubonise ukuthi ama-catechin atholakala etiyeni elimhlophe asizwa ekubuyiseleni imisipha ngokushesha kanye nokulimala okuncane kwemisipha.9).
Itiye elimhlophe libuye lithuthukise ukuhamba kwegazi futhi lihambise umoya-mpilo ebuchosheni nasezithweni. Ngenxa yalokhu, itiye elimhlophe lisebenza ngempumelelo ekwelapheni amakhanda amancane nama-aches kanye nezinhlungu ekusebenzeni.
