No ke aha i ʻokoʻa ai nā hopena sterilization ʻoiai ma ka mahana like o 121°C? — I loko o ka ʻoihana hana meaʻai, he nui nā ʻoihana e paʻa ana i kahi kuhi hewa maʻamau e pili ana i ka sterilization wela kiʻekiʻe:
"Inā hoʻomaʻemaʻe ʻia kahi huahana ma 121°C, pono ia e palekana." Eia nō naʻe, i ka hana maoli ʻana, kū pinepine kēia kūlana: ʻoiai ke hoʻomaʻemaʻe ʻia ma ka mahana like o 121°C, ʻoi aku ka lōʻihi o kekahi mau huahana ma mua o 12 mau mahina, aʻo kekahi poʻe e hoʻomohala i nā pilikia e like me ka pehu ʻana o ka ʻeke, ka rancidity a i ʻole ka haumia microbial i loko o kekahi mau pule.
No ke aha e hana ʻia ai kēia? ʻAʻole wale ka pane i ka mahana, akā, i loko o kahi mea koʻikoʻi i ka sterilization meaʻai: ka waiwai F₀.
No ke aha i ʻokoʻa ai nā hopena sterilization ʻoiai ma ka mahana like o 121°C?
ʻO ka mahana kekahi kumu wale nō ma waena o nā kūlana sterilization. No nā microorganisms, ʻo ka mea e hoʻoholo maoli ai i ka nui o ko lākou luku ʻia ʻana:
ka hopena i hui pū ʻia o ka mahana a me ka manawa.
| Huahana A | 121°C no 10 mau minuke |
| Huahana B | 121°C no 30 mau minuke |
ʻOiai ua hiki nā huahana ʻelua i ka mahana kiʻekiʻe loa like, ʻokoʻa loa ka hopena sterilization hopena.
ʻO ke kumu, ʻoi aku ka nui o ka make ʻana o ka huahana B i ka wela, hiki ke pepehi i nā microorganisms kūpaʻa i ka wela. No laila, i ka ʻoihana meaʻai, ʻaʻole hiki ke loiloi ʻia ka pono o ka sterilization ma ka mahana wale nō, akā, ma ka waiwai F₀.
He aha ka waiwai F₀?
ʻO ka waiwai F₀ (Sterilisation Value) he hōʻailona i ʻike ʻia ma ka honua holoʻokoʻa no ka ikaika o ka sterilization wela.
Ua wehewehe ʻia ʻo ia ka manawa (i nā minuke) e pono ai e hoʻokō i kahi hopena sterilizing like ma nā microorganism ma 121.1°C.
ʻO ke kiʻekiʻe o ka waiwai F₀, ʻo ka nui aʻe o ka ikaika o ka sterilization.
| F_0=3 | hōʻike i kahi hopena e like me ka sterilization hoʻomau ma 121.1°C no 3 mau minuke. |
| F_0=8 | hōʻike i kahi hopena e like me ka sterilization hoʻomau ma 121.1°C no 8 mau minuke. |
