Ama-sulfite ewayini akwenzeka ngokwezinga eliphansi emazingeni aphansi kuwo wonke amawayini, futhi ingenye yezinkulungwane zamakhemikhali ezakhiwe ngesikhathi sokuvuthwa. Kodwa-ke, ama-sulfite nawo ayengezwa yi-winemaker ukuvikela nokuvikela iwayini emabhaktheriya nasezikhungweni ezinomvubelo. Kwabanye, izifo zesibungu esibulalayo zingase zihlotshaniswe nezikhanda kanye nezono ezithandwayo emva kwesilazi noma ezimbili zewayini.
Ziyini Ama-Sulfites Futhi Avelaphi?
I-sulfur dioxide (SO2), noma ama-sulfite njengoba eyaziwa kakhulu emhlabeni wewayini, iyinhlanganisela yamakhemikhali eyenzeka ngokwemvelo emazingeni aphansi ngesikhathi sokuvuthwa kwewayini .
Ibuye ifakwe yi-winemakers amaningi ngesikhathi sokuvuthwa kwe-winemaking ukuvikela nokugcina umlingiswa wewayini, ukunambitheka, nombala. I-sulphuri dioxide yimizimba yomzimba kanye ne-antioxidant emvelo - okwenza ibe yinye yezakhamuzi eziphezulu ezitholakalayo kubavintner, njengoba ivimbela uketshezi kwewayini futhi kuvimbela ukuthi ingavumi indlela eya kuviniga. I-sulfur dioxide nayo isetshenziselwa kakhulu ezindaweni zokugcina izindlu njengengxenye yombuso wokugcina indlu - amakhemikhali anonya (ucabange i-bleach) kungaba ukuthengiswa okunzima njengendlela yokuhlanza amathangi, imishini, ama-hoses, ama-valve nezinye izinto ze-hardware ukuze i-sulfur dioxide ihlale ihlanzekile of choice.
"Iqukethe ama-Sulfites": Yini e-Label?
Imithetho yamanje ye-FDA e-United States idinga ukuthi yonke iwayini, kokubili ezifuywayo kanye nokungeniswa ngaphakathi, okuqukethe 10+ amapm of sulphuri diox state "Iqukethe ama-sulfites" kule ilebula. Le nkampani yokuqokwa kwelebula ihloselwe ukuvikela abantu okungaba yilapho isifo se-sulfites (kulinganiselwa ukuthi u-1% wabantu base-US), abantu abane-asthma basesimweni esithintekayo kakhulu.
Izimpawu zokuzwela kwe-sulfite zihlanganisa ukungqubuzana kwamanzi, ikhanda, isikhumba, i-broncho-constriction, i-nausea, ubuhlungu besisu, nesiyezi. Okumangalisa ukuthi, ngenxa yobuchwepheshe obukhona kuma-winemakers anamuhla, inani le-sulphuri dioxide kudingeka livimbele uketshezi, kuvimbele ukuvutshelwa okuqhubekayo nokuqiniswa kwewayini kusezingeni eliphansi.
Izinga eliphakeme elisemthethweni le-sulfite lamawayini e-US lungama-350 ppm, kanti amawayini amaningi ahlukanisa cishe ama-125 ppm. Amazinga okwenzeka ngokwemvelo e-sulfur dioxide ewayini, ngaphandle kwezihlanganisi zamakhemikhali, ayengalinganisa cishe ngo-10-20 ppm.
Yimaphi amawayini anamazinga aphansi kakhulu eSulfite?
Ukukhumbula ukuthi zonke iwayini ziqukethe ama-sulfite ajwayelekile, uma ufuna amawayini ngezinga eliphansi kunazo zonke ze-sulfites, ke amawayini e-organic awukubheja kwakho okuhle kakhulu, ngoba ngegama lelebula "ama- Organic Wines " akhiqizwa emvinini wamagilebhisi akhule ngaphandle kokungezwa yamakhemikhali (kufaka phakathi nesulfure dioxide) ngesikhathi sokuqothula. Iwayini elimnandi lewayini elimnandi liqukethe i-dioxide enesulfure kunazo zonke ngewayini elimnyama kanye newayini elimnandi elimnandi elimhlophe elifika ngesigamu esiseduze sokuqukethwe kwesulfur dioxide. Uma uhlola amawayini ngamazinga aphansi kunazo zonke ezenziwe nge-sulphuri dioxide uzodinga ukugijimela kumbono ohlukile futhi uhambe ngewayini elibomvu elomile ngokuqukethwe okuphansi kakhulu kwe-sulfite, okulandelwa yiwayini elimhlophe elimhlophe njengento ephakathi.
Ukuxhuma Phakathi KweSulfites Nenhliziyo
Kumele uqaphele ukuthi ama-sulfite ayeningi emithonjeni eminingi yokudla ngaphandle kwewayini. Ukudla okomile, amakhemikhali, kanye nemifino ekheniwe noma engakunqunywanga ngokuvamile inamatherafthi afakwe ekuvimbeleni ukuba abe ne-oxyidizing futhi avule isikhathi esimnyama eshalofini.
Eqinisweni, izithelo ezomile zivame ukuthwala ama-sulfite kakhulu kunebhola elivamile le-vino. Iphikisana phakathi kwama-sulfite kanye nokuhlanganiswa kwazo nekhanda lewayini liqhubeka, kanye nabantu abaningi bembonini ekhomba amaphrofamine, ama-tanins , kanye nokuphuza utshwala njengendoda yangempela. Noma ngabe yikuphi, uma othile ezwa ubudlelwane bomuntu siqu, kungase kudingeke uhlole izinketho eziphilayo ukuze ubone ukuthi lokho kushintsha umphumela.
