Jikada makhaayadda: badbaadada cuntada iyo socodka Qaabka tooska ah

Waxaad maamushaa jikada makhaayad mashquul ah: qol qaboojin, saynka maydhashada barafka, qaboojiye degdeg ah oo yar, miis uumi iyo safka kuukiyayaasha. Cuntada kulul waa inay si degdeg ah u dhex martaa aagga khatarta, cuntada qabow waa inay qabow ahaato, tigidhaduna way soo wadaan. Kani waa jilaa hawlgal — ma aha qorshe HACCP ama talo sharci.

Xakamayaal

Wuxuu xidhmo kasta oo weli qaboobaysa ugu kala qaybiyaa saxamo hudheel oo 5 cm ah (qiyaastii 1 daqiiqo-kuukiye kilo kasta).

Xidhmada ku walaaq biyo baraf leh (ilaa 25 kg). Walaaqista iyo barafka dib u dhigidda waxay khadka ka qaadaan kala bar kuukiye.

Hawo qasbaysa −5 °C ilaa 40 kg; kulaylkeedu dibadda ayuu aadaa, ma aha qolka qaboojinta.

Kuukiye kastaa wuxuu shaqeeyaa hal tigidh mar kasta (12 daqiiqo mid kasta).

Maaddooyinka diyaarinta ku soo qaado safarro la qorsheeyey oo daahda xargaha ah ka dhig xiran: albaab-furis yar oo yar.

Hawada qaboojinta waa inay ka qabow tahay 5 °C, haddii kale cuntada qolka qaboojinta lagu qaboojiyo halkaas weligeed ma gaadho.

Cuntada ku jirta godadka way ka hoosaysaa heerka la dejiyey, in ka badan marka daboolladu mar walba furmaan inta ay jirto cadaadis shaqo.

Wuxuu tuuraa xidhmo kasta oo dhaafay xadka qaboojinta — ama, haddii mid aan dhaafin, midka waqtiga ugu badan ku qaatay aagga khatarta.

Xaaladaha dhibaatada

Heerka 1 · Dufcad weyn oo chili ah adeegga ka dib

Adeegga casho wuu dhammaaday. Dheri 24 kg ah oo chili cuf ah ayaa jikada ka soo baxay 70 °C waana in la qaboojiyaa berri. Caadada caadiga ahi waa in dheriga lagu riixo qolka qaboojinta lana gurigaba tago. Ku qaboojii xadka Food Code, waqtiga aagga halista ku qaato ka dhig mid gaaban, hana tuurin.

  • Dhammaadka cunto aan buuxin shuruudaha ma jirto
  • Waxba lama tuurin
  • Dufcaddu aagga halista (5–57 °C) waxay ku jirtaa ≤ 100 daqiiqo
  • Badeecadda la keydiyey weligeed ha ka sarrayn 5 °C

Heerka 2 · Cilladda kombarasarka qolka qaboojinta adeegga dhexdiisa

Waa fiid mashquul ah kombarasarka qolka qaboojinta wuxuu bilaabaa inuu jabo: kaliya toban meelood hal awooddiisa ayaa hadhay ilaa farsamoyaqaanku yimaado qiyaastii shan saac iyo badh. Saac ka dib dheri 15 kg ah oo suugo cufan ah ayaa jikada laga soo qaadaa oo waa in la qaboojiyaa. Cuntada la keydiyey ku hay 5 °C ama ka hooseysa oo suugada waqtigeeda ku qaboojiso.

  • Badeecadda la keydiyey weligeed ha ka sarrayn 5 °C
  • Dhammaadka cunto aan buuxin shuruudaha ma jirto
  • Waxba lama tuurin

Heerka 3 · Cadaadiska cashada ee khadka kulul

Afar kuukiye ayaa si fudud u maareeya fiidkii hore. Ka dib cadaadiska ayaa dhacaya: tigidhadu way ka badan yihiin laba jibaar saddex saac iyo badh. Waqtiga tigidhada gaaban ku hay oo cuntada miiska uumiga kulul ku hay, adigoon shaqaale badan qaadin ama cuntada la hayo ilaa ay xumaato kari.

  • Waqtiga tigidhka celceliska ≤ 15 daqiiqo inta cadaadisku jiro
  • Cuntada kulul ee la hayo weligeed ha ka hoosayn 57 °C
  • Shaqaalaynta celceliska ≤ 9 kuukiye
  • Heerkulka celceliska ee cuntada kulul ee la hayo ≤ 75 °C (tayo)

Aasaas — moodelka ka dambeeya tirooyinka

Xiriir kasta oo jilaha isticmaalo, iyo ilaha uu ka yimid. Mudnaanta lagu calaamadiyay malo-awaal waa hagaajin muunad ah.

Sharciga qaboojinta Newton: farqiga u dhexeeya dhexdhexaadiyaha qaboojinta wuxuu si jibaaran u yaraadaa.
