Ikhofi ye-Decaffeinated: ukukhiqizwa, izinzuzo, izakhi, imiphumela
O ikhofi eline-decaffeinated Ikhofi elicutshunguliwe ukuze lisuse yonke i-caffeine. Izinzuzo zayo ziningi: ivimbela ukuguga kanye ne-rheumatism, ithuthukisa ukujikeleza kwegazi, isiza ukwelapha ukukhathazeka, inciphisa ingozi ye-gout, ilawula i-cholesterol, ivimbela umdlavuza, nezinye engizozichaza ngezansi.
Ikhofi ingesinye seziphuzo ezidume kakhulu emhlabeni. Yenziwe ngembewu eyosiwe negayiwe yesitshalo sekhofi. Amasimu ekhofi amakhulu atholakala emazweni ashisayo njengeBrazil, ehlanganisa cishe ingxenye yesithathu yokukhiqizwa komhlaba wonke.
Ikhofi libhekwa njengesiphuzo esishukumisayo ngenxa yokuqukethwe kwalo okuphezulu kwe-caffeine, cishe amagremu angu-40 ngamagremu angu-100 wokumnika. Lokhu kuletha izinzuzo eziningi, kodwa futhi nemiphumela eminingi engemihle engagwenywa ngokuphuza ikhofi eline-decaffeinated.
Ukukhiqizwa kwekhofi eline-decaffeinated
Ngo-1820, imbongi edumile kanye nombhali wemidlalo yeshashalazi uJohann Goethe, ephazanyiswa ukuqwasha okubangelwa ikhofi, wahlongoza umngane wakhe, usokhemisi uFriedrich Ferdinand Runge (1795-1867), ukuthi bahlaziye izingxenye zekhofi. URunge wasamukela isiphakamiso futhi ngokushesha wathola i-caffeine, isikhuthazi esabangela ukuba umngane wakhe angalali ebusuku.
Kamuva, ekuqaleni kwekhulu lama-20, uLudwig Roselius, umthengisi wekhofi waseJalimane, wathola indlela yokukhipha i-caffeine kubhontshisi. Lo mshini wawuwukucwilisa ubhontshisi wekhofi, uwushunqise, bese uwumanzisa futhi. Lokhu okuqukethwe komswakama kokugcina yikho okwaqeda i-caffeine.
Ngokushesha yathengiswa, futhi izindlela zokukhipha i-caffeine zavela futhi zaba ngcono kwaze kwaba yilapho zingasathinti iphunga nephunga lekhofi. Amanye amasu ajwayeleke kakhulu yilezi:
Ukwelashwa kwamanzi
Le nqubo yenza cishe ama-22% e-decaffeination yomhlaba wonke. Ubhontshisi wekhofi uswakanyiswe ngamanzi axutshwe nemikhiqizo yekhofi eluhlaza, enciphisa i-caffeine. Ungakwazi futhi ukuwageza ngamanzi nje. I-caffeine igxilwe ku-solvent, futhi ubhontshisi une-decaffeinated. Bese zomiswa ngomoya oshisayo.
Inzuzo yayo enkulu ukuthi kuyinqubo yemvelo, engenakho ukuxhashazwa kanye nezingozi zemvelo. Ngakolunye uhlangothi, ukukhishwa kwe-solvent kuyindlela ebiza kakhulu futhi ehamba kancane ye-decaffeination.
Inqubo ye-methylene chloride
Lena yindlela esetshenziswa kakhulu, ehlanganisa u-50% wokukhiqiza emhlabeni jikelele. Kuyindlela esebenzisa i-methylene chloride njenge-solvent yamakhemikhali. Ubhontshisi oluhlaza ucwiliswe emanzini ukuze wenze ubuso bawo bube nezimbotshana.
Zicwiliswe ku-methylene chloride kuze kube yilapho i-caffeine ichitheka. Ekugcineni, i-solvent ikhishwa kusetshenziswa i-evaporator, ubhontshisi uyagezwa ukuze ugweme ukuqhekeka, futhi womiswe ngamanzi ashisayo. I-Methylene chloride ingasetshenziswa kabusha.
Igqama ngokusebenza kwayo okuhle kakhulu kokukhipha, futhi naphezu kokuthi iyincibiliki, umthelela wayo kwezemvelo cishe awuziro. Naphezu kokugunyazwa yi-Montreal Protocol, abanye ochwepheshe bayakungabaza ukuphepha kwezinyibilikisi ze-methylene chloride; futhi bakholelwa ukuthi kudinga izimo zobuchwepheshe ezilawulwa kakhulu ukuze kugwenywe ukukhishwa komkhathi.
Ukwelashwa kwe-carbon dioxide
Sisebenzisa i-carbon dioxide ukuze sijikeleze phakathi kukabhontshisi wekhofi, siwacindezele ndawonye. Ngalokhu kucindezela, i-CO02 ithola ukuminyana okufana noketshezi kanye namandla okusabalalisa kwegesi, okukuvumela ukuthi ingene kubhontshisi futhi iqede i-caffeine.
Bese, ngesihlungi se-carbon, i-CO2 iyamuncwa (ngaphandle kwe-caffeine), iyibuyisele kumjikelezo kanye nobhontshisi obungenayo i-caffeine. Ekugcineni, ubhontshisi uvunyelwe ukuba wome emoyeni oshisayo.
Inzuzo yayo eyinhloko amandla ayo aphakeme okuncibilika, futhi uketshezi alusebenzi, alushiyi nsalela, alushi, futhi alulona usongo ongqimbeni lwe-ozone. Kodwa-ke, kudinga ukutshalwa kwezimali okubalulekile kokuqala emishinini nasekunakekeleni okulandelayo.
Ikhofi yemvelo ye-decaffeinated
Ngo-2004, abacwaningi abavela Universidade Estadual de Campinas (iBrazil) ithole ikhofi elingenayo i-caffeine ngokwemvelo. Kuyimbewu yesi-Arabhu ephuma ekuguquguqukeni okumila endle e-Ethiopia.
Lolu hlobo lwaqanjwa ngokuthi 'CA', ukuhlonipha isazi sezakhi zofuzo sase-Brazil u-Alcides Carvalho, ingqalabutho kumasu okuvikela nokuthuthukisa izitshalo zekhofi ezimelana nezinambuzane. Nakuba abacwaningi babehlose ukuthi itholakale emakethe kusukela ngo-2008, namuhla lokhu kungafezwa kuphela ngokugazinga okukhethekile.
Namuhla, ikhofi eline-decaffeinated liqukethe phakathi kuka-0,1% no-0,3% we-caffeine, kuyilapho ikhofi lemvelo liqukethe phakathi kuka-0,8% no-2,8%, kuye ngemvelaphi yalo nokuhlukahluka.
