I-tea esheshayo luhlobo lomgubo ococekileyo okanye i-granular imveliso yeti eqinileyo enokuchithwa ngokukhawuleza emanzini, ecutshungulwa ngokukhutshwa (i-extraction yejusi), ukuhluzwa, ukucaciswa, ukugxininiswa kunye nokomisa..Emva kweminyaka engaphezulu kwama-60 yophuhliso, ubuchwephesha bokwenza iti ngoko nangoko kunye neentlobo zemveliso ziye zakhula.Ngotshintsho kwiimfuno zemarike yabathengi baseTshayina kwixesha elitsha, ishishini leti elikhawulezayo lijongene namathuba amakhulu kunye nemingeni.Ihlalutya kwaye icacise iingxaki eziphambili, iphakamisa iindlela zophuhliso lwexesha elizayo kunye neemfuno zobugcisa, kwaye iqhuba uphando lobugcisa olufanelekileyo ngexesha elifanelekileyo ukuze lube ngcono Kubaluleke kakhulu ukusombulula iindawo ezithengisa iti ezisezantsi kunye nokukhuthaza uphuhliso oluzinzileyo lweti ekhawulezayo. ishishini.

Imveliso yeti ekhawulezileyo yaqala eUnited Kingdom ngeminyaka yoo-1940.Emva kweminyaka yokuveliswa kovavanyo kunye nophuhliso, iye yaba yimveliso yesiselo esibalulekileyo kwimarike.I-United States, iKenya, iJapan, iIndiya, iSri Lanka, iChina, njl.ilizwe.Uphando lweti olukhawulezileyo lwaseTshayina kunye nophuhliso lwaqala ngeminyaka yoo-1960.Emva kwe-R & D, uphuhliso, ukukhula okukhawulezayo, kunye nokukhula okuzinzileyo, i-China iye ngokuthe ngcembe yakhula yaba ngumvelisi weti okhokelayo kwihlabathi.

Kwiminyaka engama-20 edlulileyo, inani elikhulu letekhnoloji entsha kunye nezixhobo ezinje ngokutsalwa, ukwahlula, ukugxininiswa kunye nokomisa ngokuthe ngcembe kuqalise ukusetyenziswa ngokubanzi kwiimveliso zeti ezikhawulezayo, kwaye umgangatho weti ekhawulezileyo uphuculwe kakhulu.(1) Itekhnoloji yokukhutshwa okuphezulu.Njengesixhobo sokutsalwa kobushushu obuphantsi, izixhobo zokutsalwa eziguqukayo eziqhubekayo, njl.njl.;(2) iteknoloji yokwahlula i-membrane.Okufana ne-microporous filtration, i-ultrafiltration kunye nezinye izixhobo ze-membrane zokwahlula kunye nokusetyenziswa kwe-tea ekhawulezayo yokwahlula inwebu ekhethekileyo;(3) iteknoloji entsha yoxinaniso.Njengokusetyenziswa kwezixhobo ezifana ne-centrifugal encinci ye-evaporator yefilimu, i-reverse osmosis membrane (RO) okanye i-nanofiltration membrane (NF) yoxinaniso;(4) iteknoloji yokubuyisela ivumba.Njengokusetyenziswa kwesixhobo sokubuyisela ivumba le-SCC;(5) iteknoloji ye-enzyme yebhayoloji.Njenge-tannase, i-cellulase, i-pectinase, njl.(6) obunye ubugcisa.Ezifana ne-UHT (Ultra-high high instant instant instant applications).Okwangoku, itekhnoloji yaseTshayina yokwenziwa ngoko nangoko yokwenziwa kweti ikhulile ngokwentelekiso, kunye nenkqubo yetekhnoloji yokwenziwa ngoko nangoko yemveli esekwe kwisityana esinembiza enye, i-centrifugation enesantya esiphezulu, ivacuum concentration, itekhnoloji yokutshiza yokutshiza kunye ne-dynamic countercurrent extraction, ukwahlula inwebu, inwebu. ukugxininiswa, kunye nokukhenkceza kuye kwasekwa.Inkqubo yetekhnoloji yetekhnoloji yanamhlanje esekwe kubuchwepheshe obutsha obunjengokomisa.

Njengemveliso yeti efanelekileyo kunye nemfashini, iti yobisi ekhawulezayo iye yathandwa ngabathengi, ngakumbi abathengi abancinci.Ngokuqhubekayo ukujula kweti kunye nokukhuthazwa kwempilo yabantu, ukuqonda kwabantu ngemiphumo yeti kwi-antioxidant, ukulahleka kwesisindo, ukunciphisa uxinzelelo lwegazi, ukunciphisa iswekile yegazi, kunye ne-anti-allergies kuye kwanda.Indlela yokuphucula umsebenzi wezempilo weti ngesiseko sokusombulula iimfuno zokulula, imfashini kunye ne-flavour, ikwayingqwalasela ebalulekileyo yokusela iti efanelekileyo kunye nenempilo kwiqela labantu abaneminyaka ephakathi kunye nabantu abadala.Ulwalathiso olubalulekileyo lokukhuthaza ixabiso elongezelelweyo.
