Mabuku ambiri odyetsera komanso maphikidwe a mapuloteni amakuuzani kuti musagwiritse ntchito vinyo wosasa kuti musapulumuke chifukwa sizitetezeka. "Kunena zoona, pali njira yogwiritsira ntchito vinyo wosasa bwino mosamala, koma imafuna chinthu chimodzi chowonjezera. yesani vinyo wosasa kuti mutsimikizire kuti ndi ochepa kwambiri kuti aphe mabakiteriya aliwonse ovulaza.
Acidity ndi mabakiteriya
Vinyo wa vinyo wofiira (mosiyana ndi pickle zamtundu wofiira ) amadalira makamaka asidi a viniga kuti aphe mabakiteriya owopsa ndi kusunga chakudya.
Lingaliro loti "musagwiritsire ntchito vinyo wosasa chifukwa cha mafuta" ndiko kuti mulibe njira yodziwira momwe acidik wanu wokhala ndi vinyo wokhazikika amathandizira. Koma pali njira, ndipo ndi yophweka kuchita.
Chiwerengero chimene mukuyenera kukumbukira ndi asidi asidi ya 4.5%. Imeneyi ndiyo chiwerengero cha viniga wosakaniza kuti azigwiritsa ntchito popopera maphikidwe. Amagalagita ambiri amalonda ali ndi kuchuluka kwa magawo a acetic acid, kapena apamwamba (adzanena pa chizindikiro).
Kuti mudziwe ngati vinyo wokhala ndi vinyo wokhazikika ndi 4.5% kapena apamwamba, muyenera kuitanitsa chinachake chotchedwa asidi titration kit kuchokera kunyumba winemaking ogulitsa. Ziri zotsika mtengo ndipo chida chimodzi chidzakupangitsani magulu ambiri a viniga.
Chitsulo chosungiramo asidi chidzaphatikizapo:
Sironi 20 ml
150 ml kapu yopima pulasitiki
100 ml ya madzi otsika (0.2 N sodium hydroxide)
15 ml botolo la dropper la njira yowonetsera (phenolphthalein)
Chifukwa mtundu wa asidi omwe mukuyesera mu viniga ndi wosiyana ndi wa vinyo ndipo kawirikawiri pamakhala wapamwamba kwambiri, muyenera kutsata malangizo osiyana kuchokera kwa omwe akubwera ndi chida choyesa vinyo.
Mayendedwe a vinyo wa vinyo
Poyesa vinyo wosasa, choyamba mugwiritsire ntchito syringe kuti muyese 2 ml ya vinyo wosakaniza ndi kupititsa ku chikho choyesa.
Onjezerani 20 ml ya madzi ndi madontho atatu a njira yowonetsera ndi vinyo wosasa ndi kusonkhezera (ndimagwiritsa ntchito chotsitsa).
Lembani syringe ndi 10 ml ya maziko oyenera. Onetsani zowonjezereka ndikusakaniza kapu yoyesera 1 ml nthawi, oyambitsa pambuyo pa kuwonjezera.
Poyamba, madziwo adzawonekera pambuyo pa kuwonjezeka kwazomwe zimakhazikika. Potsirizira pake, zidzasintha ndipo zidzasintha. Lekani kuwonjezera zofanana pazomwezi.
Mukangomaliza madziwa, lembani momwe mumayendera kuti mufike panthawi imeneyo. Mwachitsanzo, kuyambira pomwe munayamba ndi 10 ml of basic base, ngati muli ndi 2 otsalira pambuyo kuwonjezera omwe anapanga kuyesa sampuli kusintha mtundu, ndiye anawonjezera 8 ml ya maziko ofanana.
Tsopano pakubwera masamu pang'ono. Lonjezerani chiwerengero cha milliliters chazomwe mumapanga ndi 0.6. Zotsatira zake ndizochepa peresenti ya asidi asidi mu viniga wanu. Ngati mwawonjezerapo 8 ml of base standard, mwachulukitsa 8 x 0.6 ndipo mumapeza 4.8, kapena 4,8% acetic acid.
