Ukutyhila iLogic yoKhuseleko lokutya emva kweXabiso le-F0

Kutheni iziphumo zokubulala iintsholongwane zahlukile nokuba kubushushu obufanayo be-121°C? — Kwishishini lokulungisa ukutya, iinkampani ezininzi zinombono ophosakeleyo malunga nokubulala iintsholongwane kubushushu obuphezulu:

“Ukuba imveliso ihlanjululwe kwiintsholongwane kwi-121°C, kufuneka ikhuseleke.” Nangona kunjalo, kwimveliso yokwenyani, le meko ilandelayo idla ngokuvela: nokuba ihlanjululwe kwiintsholongwane kwiqondo lobushushu elifanayo le-121°C, ezinye iimveliso zihlala ixesha elingaphezulu kweenyanga ezili-12, ngelixa ezinye zikhula iingxaki ezifana nokudumba kweengxowa, ukurhawuzelela okanye ungcoliseko lweentsholongwane kwiiveki ezimbalwa.

Kutheni oku kusenzeka? Impendulo ayikho kubushushu nje kuphela, kodwa nakwipharamitha ebalulekileyo ekubulaleni ukutya: ixabiso le-F₀.

Kutheni iziphumo zokubulala iintsholongwane zahlukile nangona iqondo lobushushu lilingana ne-121°C?

Ubushushu yinto enye nje phakathi kweemeko zokubulala iintsholongwane. Kwiintsholongwane, into egqiba ngokwenene ubungakanani bokutshatyalaliswa kwazo yile:

isiphumo esidibeneyo sobushushu kunye nexesha.

Nangona zombini ezi mveliso zifikelela kubushushu obufanayo, isiphumo sokubulala iintsholongwane esibangelwa kukwenziwa kwazo sahlukile ngokupheleleyo.

Isizathu kukuba iMveliso B ifumana ubungozi obuphezulu bokutsha, obukwaziyo ukubulala iintsholongwane ezinganyangekiyo kubushushu. Ke ngoko, kwishishini lokutya, ukusebenza kakuhle kokubulala iintsholongwane akunakuvavanywa bubushushu bodwa, kodwa kunoko ngexabiso le-F₀.

Ithini ixabiso le-F₀?

Ixabiso le-F₀ (ixabiso lokucoca umzimba) liphawu eliqatshelwayo kwihlabathi liphela lobunzulu bokucoca umzimba ngobushushu.

Ichazwa njengexesha (ngemizuzu) elifunekayo ukuze kufunyanwe isiphumo esifanayo sokubulala iintsholongwane kwiintsholongwane kwi-121.1°C.

Okukhona ixabiso le-F₀ liphezulu, kokukhona amandla okubulala iintsholongwane esanda.
