Nekuvandudzwa kwezviratidzo zvekurarama, vatengi vari kubhadhara kuwedzera kutarisa kune kunaka uye kuchengetedzeka kwenyama. Semanyama maviri makuru ezvigadzirwa, yakachekwa nyama uye nyama yechando kazhinji inyaya yekupokana nezve "kuravira" kwavo uye "kuchengeteka". Yakagadzirirwa nyama yakachengetedzeka kupfuura nyama yechando? Ita chando meats inochengeta mabhakitiriya mazhinji nekuda kwekuchengetedza kwenguva refu? Chinyorwa ichi chinonzwisisika kuongorora musiyano wekuchengetedza pakati pezviviri kuburikidza neyesainzi yekuedza data, kududzira kwenyanzvi, uye kupa Scenario kuongororwa, kupa vatengi nehwaro hwenhu hwakajeka hwekuita sarudzo.
- Yakachekwa nyama vs. Yakatemerwa nyama: Kuenzanisa kwetsanangudzo uye maitiro ekugadzirisa
1)Yakachekwa nyama: nyowani yakachengetedzwa pane yakaderera tembiricha mumamiriro ezvinhu mukati
Yakachekwa nyama, inozivikanwawo seyakatonhora-yakachengetwa nyama ine pasi peiyo yakagadziriswa acid kubviswa, inotevera aya matanho ekugadzirisa:
- Kukurumidza Kutonhorera Mushure mekuuraya: Pashure pekuuraya, iyo chitunha ichizoreredzwa kusvika 0-4 ° C mukati memaawa maviri ekudzivirira microbial kubereka.
- Lactic acid kubviswa: Inosara kuti uzorore mumamiriro ekunze ekupisa kwemaawa makumi maviri nemana kusvika kuDecoms Acctic acid, nyoro nyoro tsandanyama machira, uye kusimudzira kuravira.
- Chikukutu cheni chinotonhora mukati me: kubva pakugadzirisa kutengeswa, tembiricha inochengetwa mukati meiyo 0
2)Nyama yechando: kukurumidza kutonhora makiyi mu "yekutanga mamiriro"
Iyo yakakosha yeiyo yechando nyama yekugadzirisa iyo iri "Rapid Freezing Technology":
- Kukurumidza Kurega
- Kuchengeterwa kwenguva refu: Inogona kuchengetwa mune yekupisa tembiricha pa -18 ° C kwemwedzi 6-12 uye inofanira kudyiwa nekukurumidza mushure mekunyora mushure merying.
Misiyano Yakakosha:Yakachekwa Nyama inosimbisa "nyowani uye nyorovesa kuravira" asi ine ipfupi yekuchengetedza hwindo. Chakagadzirirwa chando chezvibayiro zvimwe kuravira kwehupenyu hwakareba.
- Yese Bacerial Kuverenga KuedzaKwayedza: Dambudziko Dual yenguva uye tembiricha
Kuti uenzanise kuchengeteka kwemhando yemhirizhonga yemhando mbiri dze nyama, inzvimbo ine mvumo yekuyedza yakaita bvunzo yakaiswa pane iyo nyama yenguruve kubva kune imwe batch, simumari mamiriro ekuchengetedza imba:
Kuedza Kugadziriswa
- SAMPLE BHUKU: Nyowani pork TenderLoin yakakamurwa muboka renyama rehuswa (firiji pa 0
- Kuedza nguva mapoinzi: Zuva 1 (yekutanga nyika), zuva 3, zuva 7, uye zuva 14 (chete neboka rechando).
- Kuedza Zviratidzo: Yese Bacerial Kuverenga (CFU / G), Coliform Bactia, uye Pathogenic Bactia (SalmonellauyeStaphylococcus Aureus).
Migumisiro Yemhedzisiro
| Kuedza Nguva | Chiverengero chehutachiona chehutachiona hwechirongwa nyama (cfu / g) | Chiverengero chehutachiona chehutachiona chema chando (cfu / g) |
| Zuva 1 | 3.2 × 10⁴ | 1.1 × 10⁴ |
| Zuva 3 | 8.5 × 10⁵ | 1.3 × 10⁴ (isina kugadziriswa) |
| Zuva 7 | 2.3 × 10⁷ (inodarika nyika yenyika) | 1.5 × 10⁴ (isina kugadziriswa) |
| Zuva 14 | - | 2.8 × 10⁴ (isina kugadziriswa) |
Kuyedzwa kwe nyama yechando mushure mekutyaira:
Mushure mekushongedza uye kuiswa mune 4 ° C nharaunda kwemaawa makumi maviri nemana, iyo nhamba yehutachiona yakakwira kusvika ku4,8
Mhedzisiro yekuedza
1) Yakatemwa Nyama: Iyo yakazara yehutachiona kuverenga inowedzera nekuwedzera nguva, inopfuura muganho we1】 10
2) Nyama yechando: Buttial kubereka kwakadzikira pa -18 ° C, asi chiitiko chehutachiona chinokurumidza kutangazve mushure mekusimuka, kukurumidza kuparara.
1 Nekudaro, iyo yakanyanya kukosha yehutachiona huwandu inogona kukonzera kudzikira uye kubva-zvinonhuwira, zvichikura njodzi yekudhakwa.

Pfungwa dzisirizvo 1: Yakachekwa nyama yakachengeteka zvakanyanya kupfuura nyama yechando?
Chokwadi: Kuchengeteka kwezvinhu zviri zviviri zvinoenderana nemamiriro ekuchengetedza. Kana churu yenyama inofumurwa pamasherufu marefu kwenguva yakareba kana kuchengetwa mumba kwemazuva anopfuura matatu, njodzi inogona kunge yakakwirira kupfuura iyo yenyama yechando.
Pfungwa dzisirizvo 2: Nyama yechando inotambura kurasikirwa kwakakura here?
Chokwadi.
Scienceficifing yekutenga uye kurudziro yekuchengetedza
1) Nekuti nyama yakajeka:
Paunenge uchitenga, tarisa iyo ruvara (tsvuku yakajeka ne gloss), kuumbwa (zvishoma kunyorovesa uye kwete kunamatira), uye kunhuhwirira (kusununguka kubva kunonhuwirira kana kurira.
Zvekuchengetedza kumba, Simbisa nyama ine purasitiki yekuputira uye inoiisa muchitokisi chetiraki yefiriji (kazhinji padyo nemadziro kumashure, uchizvipedza mukati memazuva matatu.
2)Nechando chando:
Sarudza zvigadzirwa zvine mashoma echando makristasi uye asina kunaka kurongedza, achidzivisa "nyama yeZombie" iyo yakatsika uye inopisa.
Kana tywing, shandisa "tembiricha yekudziya-tembiricha yekukwira"
3)ZVINOKOSHA ZVINOKOSHA:
Svina pamusoro peyamvura nemvura inoyerera usati wabika, asi dzivisa kusimuka kwenguva yakareba.
Ita shuwa kuti yemukati yekubheka tembiricha inosvika pamusoro 75 ° C kuti iite zvakakwana mabhakitiriya.
