Kwishishini lokucubungula ubushushu bokutya,121°C (250°F)yenye yezona zinto ziqhelekileyo. Abantu abaninzi bacinga ukuba ukutya kusoloko kukhuselekile xa kufikelelwe kwi-121°C, kwaye abanye abavelisi basebenzisa i-121°C njengobushushu obumiselweyo bokubulala iintsholongwane xa besenza iimveliso ezintsha. Nangona kunjalo, oku kukungaqondi kakuhle okuqhelekileyo.
Ukubulala iintsholongwane ekutyeni, ukusebenza kakuhle kwenkqubo akumiselwanga lixabiso elinye lobushushu. Endaweni yoko, kuxhomekeke kwisiphumo esidibeneyoubushushu kunye nexesha, echazwa njengeIxabiso le-F₀.
I-121°C bubushushu obuqhelekileyo obusetyenziswa kwihlabathi liphela xa kubalwa iinkqubo zobushushu, kodwa ayisiyiyo yodwa iqondo lobushushu elifanelekileyo lokucubungula zonke iimveliso zokutya.
Kutheni i-121°C ibe liqondo lobushushu elibhekiselele kwishishini?
121.1°C (250°F)liqondo lobushushu elisetyenziswa rhoqo ekubaleni ixabiso lokuzala kwezorhwebo (Ixabiso le-F₀) ekusetyenzisweni kobushushu bokutya.
Kobu bushushu, iintsholongwane ezimelana nobushushu ezifanaI-Clostridium botulinuminokulawulwa ngokufanelekileyo, nto leyo eyenza i-121°C ibe yindawo ebalulekileyo yokubhekisa kwiinkqubo zokubulala iintsholongwane zokutya okusemathinini okune-asidi ephantsi, ukutya okulungisiweyo, kunye nokutya kwezilwanyana zasekhaya ezimanzi.
Nangona kunjalo, kufuneka kuqatshelwe ukuba i-121°C yindlela yokubala, ayiloqondo lobushushu eliyimfuneko lokucubungula yonke imveliso yokutya.
Kutheni Zonke Iimveliso Zingasebenzisi i-121°C?
Ukutya okwahlukeneyo kuneempawu ezahlukeneyo, umxube, kunye neengozi zebhayoloji. Ke ngoko, iinkqubo zokubulala iintsholongwane kufuneka zenziwe ngokweemfuno ezithile zemveliso.
1. I-asidi yokutya ichaphazela inkqubo efunekayo
Ukutya kudla ngokuhlelwa ngolu hlobo:
- Ukutya okune-asidi ephantsi (pH > 4.6)
- Ukutya okune-asidi (pH ≤ 4.6)
Ukutya okune-asidi kudla ngokuba nokumelana okuncinci kobushushu beentsholongwane. Iimveliso ezifana nezi:
- Incindi yeziqhamo
- Iimveliso ezenziwe ngetamatato
- Ijam
- Imifuno eqhotsiweyo
isenokucutshungulwa rhoqo kumaqondo obushushu aphantsi, kuxhomekeke kwindlela ezibunjwe ngayo kunye neemfuno zenkqubo.
Ukutya okune-asidi ephantsi, kuquka iimveliso zenyama, ukutya kwaselwandle, iimveliso zobisi, kunye nokutya kwezilwanyana zasekhaya, ngokubanzi kufuna iinkqubo zobushushu ezilawulwa ngononophelo ukuze kufezekiswe ukungabi nazintsholongwane kurhwebo.
2. Imveliso Etyebileyo Ayisoloko Ifuna Ubushushu Obuphezulu
Ingcinga eqhelekileyo yile:"Okukhona imveliso ityebile, kokukhona kufuneka iqondo lobushushu lokubulala iintsholongwane libe phezulu."
Enyanisweni, oku akusoloko kunjalo.
Kwiimveliso ezifana neziqwenga zenyama yenkomo, i-congee, iisuphu ezityebileyo, kunye nebhotolo yamandongomane, umceli mngeni ophambili awukonyusa ubushushu, kodwa kukuqinisekisa ukudluliselwa kobushushu obaneleyo kwindawo ebandayo ngaphakathi kwimveliso.
Kwiimeko ezininzi, indlela efanelekileyo kukuphucula iprofayili yokufudumeza, ukulungisa ixesha lokubamba, okanye ukuguqula iinkcukacha zokupakishwa endaweni yokunyusa nje ubushushu.
3. Izinto zokuPakisha zichaphazela inkqubo yokubulala iintsholongwane
Iifomathi ezahlukeneyo zokupakisha zinemigangatho eyahlukeneyo yokumelana nobushushu, uxinzelelo, kunye neemeko zokupholisa, kuquka:
- Iibhotile zeplastiki
- Iitreyi zePP
- Iingxowa zokuma phezulu
- Iingxowa ezinamachaphaza
- Iibhotile zeglasi
- Iithini zesinyithi
Ukuba iiparameter zenkqubo azicwangciswanga kakuhle, iingxaki ezinje ngokuguqulwa kwephakheji, ukonakala kwesitywina, okanye ukuvuza zinokwenzeka nokuba inqanaba lokubulala iintsholongwane elifunekayo lifezekisiwe.
Ngoko ke, uyilo lwenkqubo yokubulala iintsholongwane kufuneka luqwalasele kungekuphela nje imveliso yokutya ngokwayo kodwa nokhuseleko kunye nokuthembeka kokupakishwa.
Ixabiso le-F₀ limisela isiphumo sokubulala iintsholongwane ngokubanzi
Kwinkqubo yokulungisa ukutya, eli shishini ligxila ngakumbiIxabiso le-F₀endaweni yokuba kubekho iqondo lobushushu elinye.
Ixabiso le-F₀ liqwalasela ubushushu bokubulala iintsholongwane kunye nexesha lokubamba, nto leyo ebonisa umlinganiselo wesiphumo sobushushu ngokubanzi ngexesha lenkqubo.
Umzekelo:
- Inkqubo ingasebenzisa ubushushu obuphezulu ixesha elifutshane, njenge-121°C ixesha elifutshane.
- Inkqubo ingasebenzisa ubushushu obuphantsi ixesha elide, njenge-115°C kunye nexesha elide lokubamba.
Ukuba nje ixabiso le-F₀ elifunekayo lifezekisiwe kwaye inkqubo iqinisekisiwe ngokufanelekileyo, iindibaniselwano ezahlukeneyo zobushushu kunye nexesha zinokuhlangabezana neemfuno zokucoca ulwelo kwezorhwebo.
Inkqubo yokubulala iintsholongwane eyilwe kakuhle ijolise ekuqinisekiseni ukhuseleko lokutya ngelixa inciphisa impembelelo kumbala wemveliso, ubume bayo, izondlo kunye nencasa.
Ukukhetha Inkqubo Efanelekileyo Yokubulala Iintsholongwane
I-121°C ayisosisombululo esiqhelekileyo kuzo zonke izicelo zokubulala iintsholongwane ekutyeni. Liqondo lobushushu eliqhelekileyo elisetyenziswa ekubaleni ukubulala iintsholongwane kurhwebo.
Kwimveliso yokwenyani, iiparameter zokubulala iintsholongwane kufuneka ziphuhliswe ngokusekelwe kwezi zinto zilandelayo:
- Udidi lokutya
- Inqanaba le-asidi
- Ifomathi yokupakishwa
- Iimpawu zokungena kobushushu
- Ixabiso le-F₀ ekujoliswe kulo
Endaweni yokusebenzisa iiparameter ezisisigxina, abavelisi kufuneka bamisele iinkqubo ngokusebenzisauvavanyo lokusasazwa kobushushu, uvavanyo lokungena kobushushu, kunye nokuqinisekiswa kwenkqubo.
Isisombululo esithembekileyo sokubulala iintsholongwane sifuna ukuhambelana okufanelekileyo phakathiiimpawu zemveliso, uyilo lwenkqubo, kunye nokukhethwa kwezixhoboNgokukhetha amacebo okulawula ubushushu, ixesha, kunye noxinzelelo olufanelekileyo, abavelisi bokutya banokuxhasa ukhuseleko lwemveliso, bagcine umgangatho, kwaye bafezekise ukusebenza okuzinzileyo kwemveliso.
