Vinyo wa sulfite mwachibadwa amapezeka pamtunda wotsika kwambiri m'ma vinyo onse, ndipo ndi imodzi mwa mankhwala ambirimbiri omwe amagwiritsidwa ntchito poyamitsa. Komabe, sulfites amawonjezeredwa ndi winemaker kuti ateteze ndi kuteteza vinyo ku mabakiteriya ndi mavitamini odzaza yisiti. Kwa ena, mitsempha ya sulfa imatha kugwiritsidwa ntchito ndi kupweteka kwa mutu komanso mankhwala osakaniza pambuyo pa galasi kapena vinyo awiri.
Kodi Sulphrates Ndi Chiyani?
Sulfure dioxide (SO2), kapena sulfite monga momwe zimadziwika bwino pa dziko la vinyo, ndi mankhwala omwe amapezeka mwachibadwa pamunsi panthawi yopangira vinyo .
Amaphatikizidwanso ndi winemakers ambiri panthawi yopuma ya winemaking kuti ateteze ndi kusunga khalidwe la vinyo, kukoma kwake, ndi mtundu wake. Sulfure dioxide imakhala ndi tizilombo toyambitsa matenda komanso tizilombo ta antioxidant - timapanga kukhala imodzi mwazolumikizana kwambiri, zomwe zimapangitsa kuti vinyo azitayidwa ndipo zimapangitsa kuti vinyo asakanike. Sulfure dioxide imagwiritsidwanso ntchito m'malo ambiri opanga zovala monga gawo la kusunga nyumba - mankhwala osokoneza bongo (kuganiza kwa bleach) angakhale ovuta kugulitsidwa ngati chokonza chokonzera zitsulo zamadzimadzi, zipangizo, mapepala, ma valve ndi zinthu zina zamtundu wa sulfure nthawi zambiri zimakhala zoyera zosankha.
"Lili ndi Sulphites": Kodi mulemba?
Malamulo amtundu wa FDA tsopano ku United States amafuna kuti ma vinyo onse, omwe am'nyumba ndi kutumizidwa kunja, omwe ali ndi 10+ ppm ya sulfuri dioxyde "Ali ndi sulfites" pa chizindikiro. Cholemba ichi chinali cholinga chowateteza anthu omwe angakhale oletsedwa ku sulfites (akuti pafupifupi 1% mwa anthu a ku United States), anthu omwe ali ndi mphumu ali m'gulu lotchuka kwambiri.
Zizindikiro za mphamvu za sulfite zimaphatikizapo kusokonezeka kwa mphuno, kupweteka mutu, khungu, khungu, kupweteka kwa m'mimba, ndi chizungulire. Chodabwitsa, chifukwa cha teknoloji yomwe ilipo kwa winemakers zamakono, kuchuluka kwa sulfure dioxide kuyenera kuletsa kutsekemera, kuteteza kuperekera kwina ndi kukhazikika kwa vinyo nthawi zonse.
Mawindo a sulfite omwe amalembedwa ndi malamulo a US vinkhwima ndi 350 ppm, ndipo ma vinyo ambiri amatha pafupifupi 125 ppm. Mawonekedwe a sulfure okosijeni m'thupi, omwe alibe vinyo, akhoza kulemera pozungulira 10-20 ppm.
Ndi Mavinyo ati Amene Ali ndi Mipata ya Sulfite Yafupi Kwambiri?
Pokumbukira kuti ma vinyo onse ali ndi sulfites mwachibadwa, ngati mukuyang'ana mavinyo ndi mlingo wotsika kwambiri wa sulfites, ndiye kuti vinyo ndiwabwino kwambiri, chifukwa ndi mawu otanthauzira mawu akuti " Organic Wines " amapangidwa kuchokera ku mphesa zopangidwa popanda kuwonjezera za mankhwala (kuphatikizapo sulufule dioxide) panthawi yopambana. Mavinyo abwino kwambiri a mchere amakhala ndi sulfure yambiri ya dioxide ndi vinyo wonyezimira komanso vinyo wofiira wonyezimira womwe umabwera mkati mwachiwiri kwa sulfur dioxide. Ngati mukufufuza vinyo ndi malo otsika kwambiri a sulfure dioxide mumayenera kusunthira kumbali yosiyana siyana ndi kupita ku vinyo wofiira wouma kwambiri kwa sulfite wokhutira, ndikutsatiridwa ndi vinyo woyera wouma ngati chisankho chokhala pakati.
Kulumikizana pakati pa Sulfites ndi kumutu
Ndibwino kuti muzindikire kuti sulphrates imapezeka muzinthu zina zambiri zopitirira vinyo. Zakudya zouma, jams, ndi zam'chitini kapena zamasamba zowonongeka nthawi zambiri zimakhala ndi sulfiti zomwe zimaphatikizapo kuti zisawonongeke ndi kutulutsa bulauni pafupipafupi.
Ndipotu, zipatso zouma zimanyamula kwambiri sulfite kuposa botolo la vino. Mtsutso pakati pa sulfite ndi mgwirizano wawo ndi mutu wa vinyo ukupitirira, ndi anthu ambiri amalonda akulozera ku histamines, tannins , ndi ndithudi mowa monga chowoneka chenichenicho. Mulimonsemo, ngati wina atha kukhala ndi anzanu payekha, kungakhale koyenera kufufuza njira zomwe mungasankhe kuti muone ngati zisintha zotsatira.
