1. Kushanduka Kwesimba reNitrite

Kushandisa spectrophotometry kuti irambe ichitarisa maitiro ekuvirisa, kuyedza kwakaratidza "double-peak curve" muhuwandu hwe nitrite. Munguva yekutanga (maawa 0-24), mabhakitiriya anoderedza nitrate akakurumidza kushandura nitrates mumiriwo kuita nitrite, zvichikwira kusvika 48 mg/kg. Muchikamu chechipiri (mazuva 3-5), kuwanda kwemabhakitiriya e lactic acid kwakaodza nitrite zvishoma nezvishoma, zvichidzosera mazinga kunzvimbo dzakachengeteka. Zvinonyanya kukosha kuti, kuwedzera kwega kwega kwe5°C mukupisa kwemhepo kwakakurudzira kuumbwa kwepamusoro pemvura nemaawa 12-18.

Kuenzanisa nekimchi yekutengeserana kwakaratidza kuti kugadzirwa kwemaindasitiri, kuburikidza nekudzora mamiriro ezvinhu nemazvo (1.5%–2.5% munyu, 15–20°C), kunoganhurira nitrite kusvika pasi pe32 mg/kg. Kusiyana neizvi, kimchi yakagadzirwa kumba, kazhinji isina kudzora tembiricha, inogara ichidarika 40 mg/kg, zvichiratidza njodzi huru dzekuchengetedza mumabasa epamba.

2. Pfungwa Dzakakosha Dzekudzora

Kuwanda kwemunyu kunobatsira zvikuru pakuenzana kwehutachiona. Kana munyu uri pasi pe1%, mabhakitiriya anokonzera zvirwere uye anoderedza nitrate anowedzera kukura, zvichikonzera kuti nitrite iwedzere kukura. Kuedza uku kwakaratidza kuti munyu we2.5% ndiwo wakanaka, zvichidzivirira mabhakitiriya ane njodzi ukuwo zvichitsigira metabolism yelactic acid bacteria.

Kudzora tembiricha kwakakoshawo. Kuvirisa pa20°C kwakaratidza kushanda kwakasimba kwehutachiona. Tembiricha dziri pamusoro pe25°C dzakakurumidza kuvirisa asi njodzi dzehutachiona dzakawedzera, nepo dziri pasi pe10°C dzakawedzera nguva yekuchengetedza kusvika pamazuva anopfuura makumi maviri. Pakuvirisa kumba, kudzora tembiricha kunokurudzirwa: 18–22°C kwemazuva matatu ekutanga, zvichiteverwa nekuisa mufiriji.

Kurapa kwekutanga kunokanganisa zvakanyanya mhedzisiro. Kubvisa kabichi mumasekonzi makumi matatu kwakaderedza huwandu hwenitrate yekutanga ne43%, zvichideredza huwandu hwenitrite yekupedzisira ne27%. Kuwedzera zvinhu zvakapfuma muvhitamini C (semuenzaniso, chili nyowani kana zvidimbu zveremoni) kwakaderedzawo huwandu hwenitrate ne15%–20%.

3. Maitiro Ekushandisa Zvakachengeteka

Zvichibva padata rekuyedza, nguva yekuvirisa inogona kukamurwa kuita zvikamu zvitatu:

Nguva yengozi (mazuva 2-5):Mazinga eNitrite anodarika mwero wekuchengetedza weChina (20 mg/kg) nekaviri kusvika katatu. Kunwa kunofanira kudzivirirwa.

Nguva yekuchinja (mazuva 6-10):Mazinga anodzikira zvishoma nezvishoma kusvika padanho rakachengeteka.

Nguva yekuchengetedzwa (mushure mezuva rechi10):Nitrite inogadzikana pasi pe5 mg/kg, zvichionekwa seyakachengeteka kudyiwa.

Maitiro Akagadziriswazvinogona kuderedza njodzi:

Nzira yekuisa munyu wakawanda (2.5% munyu wekutanga, yakawedzerwa kusvika 3% gare gare) pamwe chete nekuisa mushonga wemvura yakacheneswa we5% inopfupisa nguva yengozi kusvika kumaawa makumi matatu nematanhatu.

Kukurunga nguva dzose kuti kuore ne oxygen boost nitrite ne40%.

Pakusangana netsaona ne nitrite yakawanda, nzira dzekugadzirisa dzakashanda:

Kuwedzera 0.1% yevhitamini C powder kwemaawa matanhatu kwakaderedza nitrite ne60%.

Kusanganisa negariki itsva (3% nehuremu) kwakawana mhedzisiro yakafanana.

Chidzidzo ichi chinosimbisa kuti njodzi dziri muzvikafu zvakabikwa zvakagadzirwa kumba dzinofungidzirwa uye dzinogona kudzorwa. Nekunzwisisa mashandiro e nitrite uye kushandisa kudzora kwakarurama—sekuchengetedza 2.5% munyu, kutonga tembiricha kwakatarwa, uye kurapwa kwezvinoshandiswa pakutanga—vatengi vanogona kunakidzwa nezvikafu zvakabikwa zvechinyakare zvakachengeteka. Kuchengeta "gwaro rekuvirisa" rekutevera tembiricha, nguva, nezvimwe zvinokurudzirwa, kushandura maitiro ekicheni kuita maitiro ane ruzivo rwesainzi, anoziva njodzi.
