I roto i te umanga tukatuka wera kai,121°C (250°F)ko tētahi o ngā tino tangata e mōhiotia whānuitia ana. He tokomaha e whakaaro ana he haumaru tonu te kai ina tae ki te 121°C, ā, ka whakamahia e ētahi kaihanga te 121°C hei pāmahana whakahoromata pumau ina whakawhanake ana i ngā hua hou. Heoi, he hē noa tēnei.
Mō te whakahoromata kai, kāore te whai huatanga o te tukanga e whakatauhia e te pāmahana kotahi. Engari, e whakawhirinaki ana ki te pānga whakakotahi ote pāmahana me te wā, e whakaatuhia ana ko teUara F₀.
Ko te 121°C te pāmahana tohutoro e mōhiotia ana i te ao katoa e whakamahia ana i roto i ngā tātaitanga tukanga wera, engari ehara i te mea koinei anake te pāmahana tukatuka e tika ana mō ngā hua kai katoa.
He aha i noho ai te 121°C hei pāmahana tohutoro mō te ahumahi?
121.1°C (250°F)ko te pāmahana tohutoro e whakamahia whānuitia ana mō te tatau i te uara huakore arumoni (Uara F₀) i roto i te tukatuka wera kai.
I tēnei pāmahana, ka puta ngā moroiti ātete wera pērā i teClostridium botulinumka taea te whakahaere pai, ka waiho te 121°C hei tohutoro nui mō ngā tukanga whakahoromata o ngā kai kēne iti-waikawa, ngā kai kua oti te whakarite, me ngā kai mōkai mākū.
Heoi, me mōhio ko te 121°C he tohutoro tātaitanga, ehara i te pāmahana tukatuka whakahau mō ia hua kai.
He aha kāore e taea te whakamahi i te 121°C i ngā hua katoa?
He rerekē ngā āhuatanga, ngā hanganga, me ngā mōrearea moroiti o ia kai. Nō reira, me hoahoa ngā tukanga whakahoromata kia rite ki ngā whakaritenga motuhake o te hua.
1. Ka pā te waikawa kai ki te tukanga e hiahiatia ana
Ko ngā kai ka whakarōpūtia whānuitia hei:
- Ngā kai iti te waikawa (pH > 4.6)
- Ngā kai waikawa (pH ≤ 4.6)
He iti ake te ātete o ngā kai waikawa ki te wera o ngā moroiti. Ngā hua pēnei i:
- Wai hua
- Ngā hua e ahu mai ana i te tōmato
- Jam
- Huawhenua pītiti
ka taea te tukatuka i ngā pāmahana iti iho, i runga i te whakatakotoranga me ngā whakaritenga tukanga.
Ko ngā kai iti te waikawa, tae atu ki ngā hua mīti, ngā kaimoana, ngā hua miraka, me te kai mōkai, me tino whakahaere i ngā tukanga wera kia pai ake ai te noho huakore i roto i ngā kai arumoni.
2. Kāore e hiahiatia he pāmahana teitei ake mō te hua matotoru ake
Ko tētahi whakaaro noa ko:"Mēnā he matotoru te hua, me teitei ake te pāmahana whakahoromata."
I roto i te mahi, ehara i te mea koinei tonu te āhua.
Mō ngā hua pēnei i te poraka mīti kau, te kūkamo, te hupa matotoru, me te pata pīnati, ko te wero nui ehara i te whakanui ake i te pāmahana, engari ko te whakarite kia rawaka te whakawhiti wera ki te wāhi makariri i roto i te hua.
I ngā wā maha, ko te huarahi pai ake ko te arotau i te āhua whakamahana, te whakarerekē i te roa o te pupuri, te whakarerekē rānei i ngā whakatakotoranga mō te takai, kaua ko te whakanui noa i te pāmahana.
3. He pānga ngā rauemi takai ki te tukanga whakahoromata
He rerekē ngā taumata ātete o ngā momo tākai ki te wera, te pēhanga, me ngā āhuatanga whakamatao, tae atu ki:
- Ngā pounamu kirihou
- Ngā paepae PP
- Ngā pēke tū
- Ngā pēke pupuhi
- Ngā pounamu karāhe
- Ngā kēne whakarewa
Mena kāore i te tika te hoahoa o ngā tawhā tukanga, ka puta pea ngā raruraru pēnei i te rerekētanga o te takai, te pakaru o te hiri, te turuturu rānei ahakoa kua tutuki te taumata whakamatea e hiahiatia ana.
Nō reira, me whai whakaaro te hoahoa o te tukanga whakahoromata ehara i te mea ko te hua kai anake engari ko te haumaru me te pono o te takai.
Ko te Uara F₀ te Kaiwhakatau i te Pānga Whakahoromata Whānui
I roto i te tukatuka kai, ka aro nui te umanga ki teUara F₀kaua ki tētahi pūwāhi pāmahana kotahi.
Ka whai whakaaro te uara F₀ ki te pāmahana whakahoromata me te wā pupuri, ka hoatu he inenga o te pānga wera whānui i te wā o te tukanga.
Hei tauira:
- Tērā pea ka whakamahia he pāmahana teitei ake mō te wā poto ake i tētahi tukanga, pērā i te 121°C mō te wā poto.
- Tērā pea ka roa ake te whakamahinga o tētahi tukanga i tētahi pāmahana iti iho, pērā i te 115°C me te wā pupuri roa ake.
Mena ka tutuki te uara F₀ e hiahiatia ana, ā, ka manatokohia tika te tukanga, ka tutuki pea i ngā huinga pāmahana-wā rerekē ngā whakaritenga mō te huakita arumoni.
Ko te whāinga o tētahi tukanga whakahoromata kua hoahoa paitia kia whakarite i te haumaru o te kai me te whakaiti i te pānga ki te tae, te kakano, ngā matūkai me te reka o te hua.
Te Kōwhiri i te Tukanga Whakahoromata Tika
Ehara te 121°C i te otinga whānui mō ngā tono whakahoromata kai katoa. He pāmahana tohutoro matarohia tēnei e whakamahia ana i roto i ngā tātaitanga whakahoromata arumoni.
I roto i te mahi whakaputa tuturu, me whakawhanake ngā tawhā whakahoromata i runga i:
- Kāwai kai
- Taumata waikawa
- Hōputu mōkihi
- Ngā āhuatanga o te urunga wera
- Uara F₀ whāinga
Engari i te whakamahi i ngā tawhā pumau, me whakatū e ngā kaihanga ngā tukanga mā roto iwhakamātautau tohatoha wera, whakamātautau urunga wera, me te whakamana tukanga.
Me whai taurite tika te otinga whakahoromata pono i waenga ingā āhuatanga o te hua, te hoahoa tukanga, me te kōwhiringa taputapuMā te whiriwhiri i ngā rautaki whakahaere pāmahana, wā, me te pēhanga e tika ana, ka taea e ngā kaihanga kai te tautoko i te haumaru o ngā hua, te pupuri i te kounga, me te whakatutuki i te mahi whakaputa pumau.
