Kuki ibisubizo byo gufunga umubiri bitandukanye nubwo haba hari ubushyuhe bwa dogere selisiyusi 121? — Mu nganda zitunganya ibiribwa, amasosiyete menshi afite imyumvire itari yo ku bijyanye no gufunga umubiri mu bushyuhe bwinshi:
“Niba ibicuruzwa byasuzumwe ku bushyuhe bwa 121°C, bigomba kuba bidafite ingaruka mbi.” Ariko, mu ikorwa nyaryo, ibi bikurikira bikunze kubaho: nubwo byasuzumwe ku bushyuhe bumwe bwa 121°C, bimwe mu bicuruzwa bishobora kumara amezi arenga 12, mu gihe ibindi bikagira ibibazo nko kubyimba imifuka, gushwanyagurika cyangwa kwanduzwa na mikorobe mu byumweru bike.
Kuki ibi bibaho? Igisubizo ntikigaragara gusa mu bushyuhe, ahubwo kiri mu gipimo cy'ingenzi mu gufunga ibiryo: agaciro ka F₀.
Kuki ibisubizo byo gufunga umubiri bitandukanye nubwo byaba biri kuri dogere selisiyusi 121?
Ubushyuhe ni kimwe mu bintu bitera ubwicanyi. Ku mikorobe, ikigaragaza neza ingano y'irimbuka ryazo ni:
ingaruka z'ubushyuhe n'igihe bihuriweho.
| Igicuruzwa A | 121°C mu gihe cy'iminota 10 |
| Igicuruzwa B | 121°C mu gihe cy'iminota 30 |
Nubwo ibyo bicuruzwa byombi bigira ubushyuhe ntarengwa bumwe, ingaruka zo kubikoresha mu gukingira indwara zitandukanye rwose.
Impamvu ni uko Product B igira ingaruka ku bushyuhe bwinshi, ikabasha kwica udukoko twihanganira ubushyuhe. Kubwibyo, mu nganda z'ibiribwa, ubushobozi bwo gusukura ntibushobora gupimwa hashingiwe ku bushyuhe bwonyine, ahubwo hashingiwe ku gaciro ka F₀.
Agaciro ka F₀ ni akahe?
Agaciro ka F₀ (Agaciro ka Sterilization) ni ikimenyetso cyemewe ku rwego mpuzamahanga cyerekana ubukana bw'ubushyuhe bwo gusukura.
Bisobanurwa nk'igihe (mu minota) gisabwa kugira ngo habeho ingaruka zingana zo gusukura udukoko ku bushyuhe bwa 121.1°C.
Uko agaciro ka F₀ kaba kari hejuru, niko imbaraga zo gusukura ziyongera.
| F_0=3 | bigaragaza ingaruka zingana no gusukura buri gihe kuri 121.1°C mu gihe cy'iminota 3. |
| F_0=8 | bigaragaza ingaruka zingana no gusukura buri gihe kuri 121.1°C mu gihe cy'iminota 8. |
