1. Mgbanwe Mgbanwe nke Nitrite

Site n'iji spectrophotometry na-enyocha usoro ịgba mmiri mgbe niile, nnwale ahụ gosiri njirimara "usoro elu okpukpu abụọ" na ọdịnaya nitrite. N'oge mbụ (awa 0-24), nje bacteria na-ebelata nitrate gbanwere nitrates na akwụkwọ nri ngwa ngwa ka ọ bụrụ nitrite, na-amụba ọkwa ruo 48 mg/kg. Na nkebi nke abụọ (ụbọchị 3-5), mmụba nke nje bacteria lactic acid na-emebi nitrite nwayọọ nwayọọ, na-eweghachi ọkwa na oke nchekwa. Ihe pụrụ iche bụ na kwa 5°C na-abawanye na okpomọkụ gburugburu na-eme ka mmepụta elu dị elu site na awa 12-18.

Ntụnyere ya na kimchi azụmaahịa gosiri na mmepụta ụlọ ọrụ mmepụta ihe, site na njikwa ziri ezi nke ọnọdụ (1.5%–2.5% nnu, 15–20°C), na-ebelata oke nitrite ka ọ ghara ịdị n'okpuru 32 mg/kg. N'ụzọ dị iche, kimchi e ji aka mee, nke na-anaghị achịkwa okpomọkụ, na-agafekarị 40 mg/kg, nke na-egosi nnukwu ihe egwu nchekwa n'ụlọ.

2. Isi Ihe Njikwa Dị Mkpa

Njupụta nnu na-arụ ọrụ dị mkpa na nguzozi nje. Mgbe nnu dị n'okpuru 1%, nje bacteria na-akpata ọrịa na-emebi ihe na nitrate na-etolite, na-eme ka elu nitrite dị elu na nke mbụ. Nnwale ahụ chọpụtara na nnu 2.5% dị ka nguzozi kachasị mma, na-egbochi nje bacteria na-emerụ ahụ nke ọma ma na-akwado metabolism nke nje bacteria lactic acid.

Ndozi okpomọkụ dịkwa oke mkpa. Ịgbanye ọkụ na 20°C gosiri ọrụ nje bacteria kacha sie ike. Okpomọkụ karịrị 25°C mere ka ịgbaze ngwa ngwa mana ọ na-eme ka ihe egwu nke enweghị nhazi nke nje bacteria dịkwuo elu, ebe ihe na-erughị 10°C gbatịkwuru oge nchekwa ruo ihe karịrị ụbọchị 20. Maka ịgbaze ọkụ n'ụlọ, a na-atụ aro ka achịkwa okpomọkụ nke ọma: 18–22°C maka ụbọchị atọ mbụ, wee tinye ya na friji.

Ọgwụ tupu e jiri ya mee ihe na-emetụta ihe si na ya pụta nke ukwuu. Ịchacha kabeeji ruo sekọnd iri atọ belatara ọdịnaya nitrate mbụ site na 43%, na-ebelata oke nitrite ikpeazụ site na 27%. Ịtinye ihe ndị bara ụba na vitamin C (dịka ọmụmaatụ, chili ọhụrụ ma ọ bụ mpekere lemon) belatara oke site na 15%–20%.

3. Atụmatụ oriri dị mma

Dabere na data nnwale, enwere ike kewaa usoro oge ịgba mmiri n'ime usoro atọ:

Oge ihe egwu (ụbọchị 2–5):Ọkwa nitrite karịrị ọkọlọtọ nchekwa nke China (20 mg/kg) ugboro abụọ– atọ. A ghaghị izere iri ya.

Oge mgbanwe (ụbọchị 6–10):Ọkwa na-ebelata nwayọ nwayọ ruo n'ókè dị nso na nchekwa.

Oge nchekwa (mgbe ụbọchị nke iri gasịrị):Nitrite na-ada ada n'okpuru 5 mg/kg, a na-ewere ya dị ka ihe dị mma maka oriri.

Usoro kachasị mmanwere ike ibelata ihe egwu:

Usoro nnu gradient (2.5% nnu mbụ, mụbara ruo 3% mgbe e mesịrị) yana ịgba ọgwụ mmiri brine 5% dịla ndụ na-eme ka oge ihe egwu dị obere ruo awa 36.

Nkwalite mgbe niile iji mee ka ikuku oxygen mụbaa site na 40%.

Maka mkpughe nke nwere oke nitrite n'amaghị ama, usoro ndozi gosipụtara na ọ dị irè:

Itinye ntụ ntụ vitamin C 0.1% ruo awa isii belatara nitrite site na 60%.

Ịgwakọta ya na galik ọhụrụ (3% site na ibu) nwetara otu ihe ahụ.

Nnyocha a na-akwado na ihe egwu dị na nri e ji aka mee bụ ihe a ga-ahụ anya ma nwee ike ịchịkwa. Site n'ịghọta usoro nitrite na itinye njikwa ziri ezi n'ọrụ - dịka idobe nnu 2.5%, njikwa okpomọkụ edobere, na ọgwụgwọ tupu e jiri ya mee ihe - ndị na-eri nri nwere ike ịnụ ụtọ nri ọdịnala e ji aka mee n'enweghị nsogbu. A na-adụ ọdụ ka ha debe "ndekọ ịgbaze" iji soro okpomọkụ, oge, na paramita ndị ọzọ, na-agbanwe omume kichin ka ọ bụrụ usoro sayensị na-eme nke ọma, nke a na-aghọtaghị ihe egwu dị na ya.
