He aha i rerekē ai ngā hua o te whakahoromata ahakoa i te pāmahana kotahi o te 121°C? — I roto i te umanga tukatuka kai, he maha ngā kamupene e whai whakaaro hē ana mō te whakahoromata i te pāmahana teitei:
"Ki te whakahoromatatia tētahi hua i te 121°C, me noho haumaru." Heoi, i roto i te hanga tuturu, ka puta pinepine te āhuatanga e whai ake nei: ahakoa kua whakahoromatatia i te pāmahana kotahi o te 121°C, ka roa te ora o ētahi hua neke atu i te 12 marama, ko ētahi ia ka pāngia e ngā raruraru pēnei i te pupuhi o te pēke, te pirau, te poke rānei i te moroiti i roto i ētahi wiki.
He aha tēnei i puta ai? Ehara i te mea ko te pāmahana anake te whakautu, engari kei roto hoki i tētahi tawhā nui mō te whakahoromata kai: te uara F₀.
He aha i rerekē ai ngā hua o te whakahoromata ahakoa i te pāmahana kotahi 121°C?
Ko te pāmahana tētahi o ngā āhuatanga o te whakahoromata. Mō ngā moroiti, ko te mea e whakatau ana i te nui o tō rātou whakangaromanga ko:
te pānga ngātahi o te pāmahana me te wā.
| Hua A | 121°C mō ngā meneti 10 |
| Hua B | 121°C mō te 30 meneti |
Ahakoa ka eke ngā hua e rua ki te pāmahana mōrahi ōrite, he rerekē rawa te hua o te whakahoromata.
Ko te take he nui ake te kaha o te Hua B ki te patu i ngā moroiti ātete wera. Nō reira, i roto i te umanga kai, kāore e taea te aromatawai i te whai huatanga o te whakahoromata mā te pāmahana anake, engari mā te uara F₀.
He aha te uara F₀?
Ko te uara F₀ (Uara Whakahoromata) he tohu e mōhiotia ana i te ao mō te kaha o te whakahoromata wera.
Ko te wā (i roto i ngā meneti) e hiahiatia ana hei whakatutuki i tētahi pānga whakahoromata ōrite ki ngā moroiti i te 121.1°C.
Ka nui ake te uara F₀, ka nui ake te kaha o te whakahoromata.
| F_0=3 | e tohu ana i tētahi pānga e ōrite ana ki te whakahoromata tonu i te 121.1°C mō te 3 meneti. |
| F_0=8 | e tohu ana i tētahi pānga e ōrite ana ki te whakahoromata tonu i te 121.1°C mō te 8 meneti. |
