"Ua hana ʻia kēia hiki no hoʻokahi makahiki, no ke aha i loko o ke ola o ka papa?Hiki ke ʻai ʻia?He nui nā mea mālama i loko?Hiki ke palekana kēia?"Nui nā mea kūʻai e hopohopo e pili ana i ka mālama lōʻihi.Hiki mai nā nīnau like mai ka meaʻai hiki, akā ʻoiaʻiʻo, hiki ke mālama ʻia ka meaʻai hiki no ka manawa lōʻihi ma o ka sterility pāʻoihana.
ʻO ka meaʻai hiki ke pili i nā meaʻai maka i hana mua ʻia, hiki ke hoʻopaʻa ʻia i loko o nā kini hao, nā ʻōmole aniani, nā plastics a me nā ipu ʻē aʻe, a laila sterilized e hoʻokō i ka sterility pāʻoihana a hiki ke mālama ʻia i ka lumi wela no ka manawa lōʻihi.Hoʻokaʻawale ʻia ka sterilization o ka meaʻai canned i ʻelua mau ʻano: ʻo ka meaʻai haʻahaʻa haʻahaʻa me ka waiwai pH ʻoi aku ka nui ma mua o 4.6 pono e sterilized e ka wela kiʻekiʻe (e pili ana i 118°C-121°C), a me ka meaʻai waikawa me ka waiwai pH ma lalo o 4.6, e like me ʻO nā hua kēne, pono e hoʻopili ʻia (95°C-100°C).
Hiki paha i kekahi poʻe ke nīnau inā ua luku ʻia nā meaʻai i loko o ka meaʻai ma hope o ka hoʻomaʻemaʻe ʻia ʻana o ka meaʻai hiki i ke kiʻekiʻe?ʻAʻole ʻai hou ka meaʻai hiki ke ʻai?Hoʻomaka kēia me ka sterility pāʻoihana.
Wahi a ka "Canned Food Industry Handbook" i paʻi ʻia e China Light Industry Press, ʻo ka sterility pāʻoihana e pili ana i ka ʻoiaʻiʻo o nā meaʻai like ʻole ma hope o ka hiki ʻana a me ka hoʻopaʻa ʻana i nā waiwai pH ʻē aʻe a me nā bacteria like ʻole i lawe ʻia e lākou iho.Ma hope o ka hoʻāʻo ʻepekema a me ka helu koʻikoʻi, ma hope o ka sterilization haʻahaʻa a me ka hoʻoluʻu ʻana i nā mahana like ʻole a me nā manawa, ua hana ʻia kahi ʻōpala, a ua pepehi ʻia ka bacteria pathogenic a me ka bacteria spoilage i loko o ke kini ma o ka sterilization kaʻina, a me nā meaʻai a me ka ʻono o ka meaʻai ponoʻī. mālama ʻia i ka nui loa.Loaʻa iā ia ka waiwai kālepa i ka wā e mālama ʻia ai ka meaʻai.No laila, ʻo ke kaʻina hana sterilization o nā meaʻai canned ʻaʻole ia e pepehi i nā hua bacteria a pau, akā e hoʻopaʻa wale i nā bacteria pathogenic a me nā bacteria spoilage, mālama i nā meaʻai, a ʻo ke kaʻina hana sterilization o nā meaʻai he nui nō hoʻi kahi kaʻina kuke, e ʻoi aku ka maikaʻi o ko lākou kala, ʻala a me ka ʻono.ʻOi aku ka mānoanoa, ʻoi aku ka momona a ʻoi aku ka ʻono.
No laila, hiki ke hoʻokō ʻia ka mālama lōʻihi o ka meaʻai canned ma hope o ka pretreatment, canning, sealing and sterilization, no laila ʻaʻole pono ka meaʻai hiki ke hoʻohui i nā preservatives a hiki ke ʻai ʻia me ka palekana.
