Ngakanani i-caffeine equlethwe kwikhofi ye-decaffeinated?

Ukusetyenziswa kwekhofi kunika izibonelelo ezithile zezempilo. Oku, umzekelo, ukhusela isibindi, kunciphisa umngcipheko wesifo sikashukela kunye nezifo zentliziyo. Kodwa ngaba unokufumana impembelelo xa usela i-coffee decaffeinated?

Mhlawumbi uvile ukuba le khofi iqulethe ipesenti yale nto, kwaye yinyaniso. Into efana ne-caffeine, iqule ii-cocoa. Kodwa ukuba ufumane umphumo ofanayo kunye nekhofi rhoqo, kufuneka uphuze izitya ezininzi.

Ngakanani i-caffeine apho apho akufanele kube khona?

Inkqubo ye-decaffeination ivame ukukhokelela ekususweni kweepesenti ezingama-94-98 zale mveliso kwi-grains. Nangona kungekho mithetho esemthethweni malunga nento ebizwa ngokuba yi-caffeine-free, kukholelwa ukuba i-97% ye-caffeine kufuneka isuswe kuyo.

Ngokomyinge, i-450 ml yekhofi eqhelekileyo iqukethe i-188 milligrams ye-caffeine, ngelixa enye indebe ye-decaffeinated iqukethe i-9.4 milligrams, ngo-2006 uphando olwenziwa ngabaososayensi baseYunivesithi yaseFlorida. Abaphandi bathi kufuneka uphuze kwiikomityi ezinhlanu ukuya kwezilishumi ukuze uzive umphumo.

Umxholo we-caffeine kwisiphuzo, apho akufanele kube khona, uhluka kuye kuxhomekeke kukuphi uhlobo lwezityalo ezisetyenzisiweyo, kunye nendlela inkqubo ye-decaffeination eyenziwa ngayo. Ukulungiselela ubhontshisi bekhofi, le nqubo iqhutshwa ngokusebenzisa enye yeendlela ezintathu-usebenzisa amanzi, iikhemikhali okanye i-carbon dioxide. Uphononongo olufanayo lulwazi oluvela eFlorida lubonisa ukuba umxholo we-caffeine kwikhobe yekhofi, ebonwa ngokuba yi-beskofeenovym, iyahluka ngokubanzi, kwaye kuya kufuneka ufune isiselo esingenalo nhlobo.

Iziphumo zophando lwezesayensi

Ngokwenziwe uphando, izazinzulu zakhetha iisampulu ezazithobela i-decafeination, ezivela kubakhiqizi abahlukeneyo aba-10. Inani elikhulu le-caffeine abayifumene kulezi sampuli ngu-13.9 mg, oko kukuthi, malunga neshumi elinesithathu kwisixa sayo kwikofi eqhelekileyo. Kwaye isampuli esisodwa kuphela sasine-decaffeinated ngokuphelele.

Umxholo we-caffeine e-espresso, ukulungiswa okungafaniyo nokulungiselelwa kwekhofi rhoqo, kwahluke. Ngokomyinge, i-espresso iqukethe ii-milligram ze-caffeine. Emva kokuhlaziywa, ihlala ivela kuma-3 ukuya kuma-15.8.

Ngaba kufanelekile ukukhathazeka

Kodwa ukuba awukwazi ukusebenzisa i-caffeine ngenxa yezizathu, kwaye ngoko ukhetha ikhofi ngaphandle kwayo, ungakhathazeki: nangona ufumana ikhofi eyenzayo, akunakwenzeka ukuba oku kuya kukuchaphazela kakhulu. Iiprofesa ezivela kwiyunivesithi efanayo eFlorida zithi, cishe, akukho nto iya kwenzeka, kwaye umphumo awuyi kubonakala.
