Ntawm daim ntawv lo ntawm yuav luag txhua cawv, tsis hais txog nws cov nqi thiab keeb kwm, koj tam sim no tuaj yeem pom qhov ntsuas ntawm cov ntsiab lus ntawm sulfur dioxide. Cov tshuaj no, tseem hu ua sulfur dioxide lossis sulfur dioxide, tau muab cais ua cov tshuaj lom, yog li yuav tsum tau ntxiv cov tshuaj sulfur dioxide rau cov cawv feem ntau tau nug. Txawm li cas los xij, kev siv cov sulfurous anhydride hauv kev tsim cov cawv txiv hmab yog qhov tseeb heev thiab tau piav qhia los ntawm cov laj thawj vim li cas.
Vim li cas tsim nyog sulfur dioxide?
Sulfurous anhydride tau siv txij li puag thaum ub los. Hauv Nrab Hnub nyoog, fumigation ntawm cov ntim cawv nrog cov nplaim ntses cov nplais tau siv dav los tswj cov dej cawv zoo dua. Medieval winemakers tau paub txog cov tshuaj lom ntawm cov tshuaj lom neeg no; yog li ntawd, fumigation ntawm cov ntim cawv nrog cov leej faj yog txwv lossis txwv ntau dua ib zaug txhawm rau txhawm rau tiv thaiv kev noj qab haus huv ntawm cov neeg siv khoom.
Txawm li cas los xij, lawv tsis tuaj yeem tso cov sulfur dioxide, thiab thaum pib ntawm lub xyoo pua xeem lawv pib siv nws hauv kev tsim cov cawv, ntxiv cov khoom no rau cov khoom siv cawv lossis ua tiav rau hauv cawv ua kom tsis txhob muaj kab mob loj hlob, pwm thiab poov xab tsiaj qus.
Sulfur dioxide tsis tsuas yog tswj cov microflora ntawm cov cawv thiab cov cawv, tiv thaiv cov kab mob hloov hauv lawv, tab sis kuj tiv thaiv oxidation. Nws ua tsaug rau sulfurous anhydride uas tus caw khaws nws cov xim, saj thiab aroma.
Sulphur dioxide tseem tuaj yeem txhawb nqa cawv txiv hmab, vim tias kab lis kev cai tsis tuag nyob hauv nws cov cawv.
Nws tseem tseem tsis tau pom qhov hloov chaw txaus rau sulfurous anhydride - cov tshuaj muaj tsawg toxicity tsis muaj cov khoom tsim nyog antibacterial thiab antioxidant, thiab ua kom tsis zoo rau cov dej haus. Tsuas yog cov neeg tsim khoom ntawm cov organic organic kim tuaj yeem tswj cov kev xyaum yam tsis ntxiv sulfur dioxide lossis tsawg tshaj plaws ntawm nws - txiv kab ntxwv rau lawv cov ntau lawm hauv thaj chaw huv ecologically, tshuaj thiab cov thev naus laus zis tsis siv nyob rau hauv kev tsim cov dej haus, fermentation tshwm sim zoo li qub Tab sis txawm hais tias organic cawv muaj me me ntawm sulfurous anhydride tso tawm thaum lub sijhawm fermentation.
Kev zoo nyob ntawm qhov ntau
Txawm hais tias tag nrho nws cov txiaj ntsig zoo, sulfur dioxide tseem yog ib qho tshuaj lom uas tuaj yeem ua rau muaj kev mob nkeeg rau kev noj qab haus huv siab, thiab ua rau muaj qhov tsis haum. Txawm li cas los xij, nyob rau hauv cov koob tshuaj uas ua rau cov kev xav tsis haum, qhov khoom no tsuas yog tsis ntxiv rau cawv. Nws cov ntsiab lus hauv caw tsis tshaj 160-400 milligrams ib liter ntawm haus. Nyob rau tib lub sijhawm, cov tuam txhab tsim tawm sim txo cov ntsiab lus ntawm leej faj dioxide hauv cov khoom tiav ntau li ntau tau, vim tias nws txoj kev ua ntau dhau muaj qhov tsis zoo ntawm kev saj ntawm caw.
Cov neeg tsim khoom muaj txoj cai tsis kam qhia ntawm daim ntawv tso cai ntawm cawv txiv hmab seb puas muaj sulfurous anhydride nyob rau hauv nws, txawm li cas los xij, yog tias koj yuav tsis muaj cov organic caw tsawg, cov tshuaj muaj peev xwm tau lees tias nyob hauv cov dej haus.
Yog hais tias cov txheej txheem thev naus laus zis tau ua txhaum thaum lub sijhawm ua cawv txiv hmab, nws cov saj yuav hloov pauv - muaj cov hmoov hlau tsis muaj zog, txawv txav rau cov cawv no, tsis hnov tsw tsw. Kev haus dej haus ib qho zoo li no yuav ua rau mob taub hau, xeev siab thiab mob nyhav hauv plab, feem ntau yuam kev rau cov tsos mob hangover. Rau kev fab tshuaj tsis haum, nws zoo dua tsis txhob siv cov khoom lag luam txhua lub sijhawm - qhov zoo ntawm qhov tsis xav tau (txog kev ua tsis taus pa) nce ntau zaus.
