Hangarau Tiaki Hua Ika
He puna nui ngā hua ika pērā i te ika, te kōura, te wheke, te mātaitai, me ētahi atu momo koiora wai mō te pūmua kararehe mō te hapori. Haunga te nui o ō rātou uara kai, he nui hoki te uara ōhanga o ngā taonga ika nā te mea he rauemi mata mō te kai o te whare me te ahumahi. Heoi, ahakoa tēnei pūmanawa, he kai pirau ngā hua ika. Kia hopukina, kia hauhaketia rānei te ika, ka tere heke te kounga nā te mahi whākōkī, te tipu o ngā moroiti, me ngā tauhohenga matū pērā i te waikura ngako. Nō reira, ko te hangarau tiaki hua ika te mea nui ki te pupuri i te kounga, te whakaroa i te roa o te oranga o te kai, te whakarite i te haumaru o te kai, me te whakanui ake i te uara tāpiri o te hua.
He aha i tere ai te ngaro o ngā hua ika?
I te nuinga o te wā, he nui te wai o ngā ika me ngā hua ika, he kiko ngohengohe, ā, he matūkai hoki hei tautoko i te tipu o ngā huakita. I muri i te matenga o te ika, ka mutu tana pūnaha ārai mate, ka taea ai e ngā moroiti mai i te mata, i ngā pihanga, me ngā whekau te tupu. Hei tāpiri, ka noho tonu ngā whākōkī taiao i roto i te tinana o te ika, ā, ka whakaoho i te autolysis, he tukanga pirau kiko e puta ai he kakano ngohengohe me te haunga kino. He rite tonu te hiranga, ka ngawari ngā ika momona ki te pirau nā te waikura, inā koa ka pāngia e te hau, te mārama, me te pāmahana teitei. Nā tēnei huinga o ngā āhuatanga he mea nui te tiaki mai i te wā tuatahi o te whakahaere.
Ngā Mātāpono Taketake o te Hangarau Tiaki
Ko te whāinga matua o te hangarau tiaki ika he aukati, he whakamutu rānei i ngā take o te pirau. Ko ētahi o ngā mātāpono e whakamahia whānuitia ana ko: te whakaheke i te pāmahana hei whakaroa i te mahi a te moroiti me te whākōkī; te whakaiti i te nui o te makuku, te mahi wai rānei hei ārai i te tipu o te huakita; te tāpiri i ngā mea tiaki taiao, matū rānei (e ai ki ngā tohutohu) hei aukati i ngā moroiti; te whakaiti i te pā atu ki te hāora; me te whakamahana hei patu i ngā moroiti. He maha ngā tikanga tiaki hou e whakamahi ana i te huinga o ēnei mātāpono hei whakanui ake i te whai huatanga.
Te Whakamatao me te Whakatio
Ko te tikanga tino noa, ā, he māmā noa iho, ko te whakamatao ki te hukapapa, ki te pouaka whakamātao rānei. Mā te whakamatao ki ngā pāmahana tata ki te 0–4°C ka taea te whakaroa i te pirau, engari kāore e taea te aukati katoa. Nō reira, i te wā e whakahaere ana i ngā ika i runga kaipuke, i te wā rānei e hauhake ana i ngā ika, ka whakamahia te hukapapa papatahi, te hukapapa nui rānei hei whakamatao tere i te ika. Ka whakarerekētia te ōwehenga o te hukapapa ki te ika i runga i te roa o te haerenga me ngā āhuatanga o te rangi.
Mō te rokiroki roa, ko te tio te kōwhiringa matua. Ka tiohia ngā ika i ngā pāmahana i raro i te -18°C kia tata mutu ai te tipu o ngā moroiti. He pai ake te tio tere i te tio puhoi nā te mea ka hangaia he tioata huka iti ake, ka whakaiti i te kino o te kiko. Kātahi ka rongoatia te hua tio ki roto i te rokiroki matao ka tohatohahia puta noa i te mekameka matao. Ko ngā wero o tēnei tikanga ko ngā utu pūngao, ngā whakaritenga o te whare, me te mōrearea o te hekenga o te kounga nā te piki me te heke o te pāmahana, te rewa tonu rānei.
Te Whakamaroke me te Matewai
He tikanga tuku iho whai hua te whakamaroke, inā koa i ngā rohe takutai. Ka whakamarokehia ngā ika i te rā, ka whakamahia rānei he whakamaroke mīhini. Ko te whāinga he whakaiti i te makuku kia kore ai e tipu ngā moroiti. Ko ngā hua noa ko ngā ika tote maroke, ngā ika wai māori maroke rānei. Ahakoa he iti te utu, he ngoikoretanga anō hoki ō te whakamaroke tuku iho pērā i te whakawhirinaki ki te huarere, te mōrearea o te puehu me te poke o ngā pepeke, me te kounga koretake.
Ko ngā hangarau hou ake ko ngā whakamaroke kāpata, ngā whakamaroke kauhanga, me te whakamaroke hau wera whakahaeretia. Kei reira anō te whakamaroke-tio, e whakaputa ana i ngā hua tino maroke, kounga teitei, engari he utu nui. Nō reira, ko tēnei tikanga e whakamahia ana mō ngā hua utu nui, mō ngā hiahia motuhake rānei.
Te Tote, te Whakareka, me te Whakapūkara
Ko te mahi a te tote mā te kukume wai mai i ngā kiko ika mā te osmosis, ka whakaiti i te mahi wai me te aukati i te tipu o ngā moroiti. Ka taea te tote i te maroke (te tote maroke) te mākū rānei (te tote parai). He maha ngā wā ka honoa te tote me te whakamaroke kia roa ai te ora o ngā ika tote. Ahakoa he whai hua, ka taea e te tote te whakanui ake i ngā taumata konutai, he āwangawanga hauora tēnei.
Haunga te tote, ka whakamahia te huka e ētahi hua hei tiaki, hei tauira i roto i ētahi whakaritenga reka. Ko te whakapūkara, i tētahi atu ringa, he hangarau tuku iho e whakamahi ana i ngā moroiti whai hua hei whakaputa i ngā matū e aukati ana i ngā huakita pirau me te hanga i tētahi reka motuhake. Hei tauira, ko te whakapiri parāoa, te bekasam, te peda, me ētahi atu hua ika whakapūkara. Ko ngā kī ki te whakapūkara angitu ko te horoi, te hanganga o ngā kai, me te whakahaere i te pāmahana me te roa mō te haumaru me te ōritetanga.
Te whakapūpū
He tikanga tiaki me te whakareka te auahi. Kei roto i te auahi ngā matū patu huakita me ngā matū ārai mate, ā, ka āwhina hoki te tukanga ki te whakaiti i te nui o te wai. Kei reira te auahi wera, e tunua ai te ika i te wā e tiakina ana, me te auahi matao, e mahia ana i ngā pāmahana iti ake hei pupuri i tētahi kakano motuhake. Ka whakamahia e te auahi tuku iho he oumu, ko te auahi hou ia ka whakamahia he whare auahi me te pāmahana me te tohanga auahi kua whakahaeretia ake. Ko ngā wero ko te whakahaere kounga me te kaha ki te hanga i ngā matū kāore e hiahiatia mena kāore i oti te tukanga tahunga, nō reira ka whakamahia e te hangarau hou te auahi wai, te tahunga whakahaeretia rānei.
Te Tāne me te Whakahoromata
He tikanga tiaki tino whai hua te whakakī ika mō te tohatoha tawhiti me te rokiroki roa i te pāmahana rūma. Ko te tukanga ko te whakakī i ngā ika ki roto i ngā kēne, te tāpiri i tētahi mea (hinu, ranu, wai tote rānei), te pana i te hau, te hiri, kātahi ka whakahoromata mā te whakamahi i te wera nui. Ko te whāinga o te whakahoromata he patu i ngā moroiti mate, tae atu ki te Clostridium botulinum kino. Ko ngā hua pēnei i te sardine kēne, te tuna kēne, me te makarele kēne e mōhiotia whānuitia ana mō tō rātou ngāwari me te roa. Heoi, he nui te haumi ki ngā taputapu, ā, me piri te tukanga ki ngā paerewa tino pakari hei whakarite i te haumaru.
Tākai Hou: Tākai Korehau me te Āhua Kua Whakarerekētia (MAP)
Kei te tere haere te whanaketanga o te hangarau tākai, ā, kua noho hei wāhanga nui o te tiaki kai. Ka tangohia e te tākai korehau te hau i roto i te tākai, ka whakaiti i ngā taumata hāora, ka āwhina ki te whakaroa i te waikura ngako me te tipu o ngā huakita aerobic. I taua wā, ka whakakapia e te MAP (Modified Atmosphere Packaging) te hau i roto i te tākai ki te ranunga o ngā hau pērā i te hauhā me te hauota hei aukati i ngā moroiti. He whānuitia te whakamahinga o tēnei tikanga mō ngā ika hou, ngā kōura kua tihoretia, me ngā hua kua rite ki te tunu. Ahakoa he whai hua, ko te angitu o te MAP kei runga tonu i te iti o te pāmahana rokiroki me te tukanga whakaputa ma.
Hangarau Tiaki Rauemi Taiao
Ko ngā au o nāianei e pai ake ana ki ngā mea tiaki taiao. He maha ngā rangahau kua whakawhanake i te whakamahinga o ngā tangohanga tipu (hei tauira, te kāriki, te kanekane, te rosemary), te chitosan mai i ngā para anga kōura, me ngā matū patu huakita taiao pērā i te nisin. Hei tāpiri, mā te paninga o ngā paninga kai ka taea te whakaiti i te pānga o te hāora ki ngā ika, ā, ka puhoi te ngaronga o te wai. Ehara i te mea ka roa ake te ora o ngā ika i roto i tēnei mahi auaha, engari ka tautoko hoki i te ariā o te ahumahi matomato me te whakamahinga o ngā para hī ika.
Te Mana Kounga me te Haumaru Kai
E kore e tino pai te hangarau tiaki kai me te kore e tika te whakahaere i muri i te kotinga. He mea nui ngā mahi pēnei i te horoi tere, te tango otaota, me te horoi ki te wai ma mō te kounga whakamutunga. Hei tāpiri, he mea nui te whakatinana i tētahi pūnaha whakahaere haumaru kai pēnei i te HACCP (Tātari Tūponotanga me ngā Pūwāhi Mana Tino) mō te umanga tukatuka ika. Me pupuri tonu te aroturukitanga pāmahana, te akuaku o ngā kaimahi, te akuaku o ngā taputapu, me te kounga o ngā rauemi mata kia haumaru ai, kia pau ai hoki ngā hua.
Te Katinga
He mahi rautaki tā te hangarau tiaki ika hei pupuri i te wātea o ngā kai totika, hei whakaiti i ngā ngaronga i muri i te kotinga, me te whakanui ake i te whakataetae o ngā hua ika. Mai i ngā tikanga tuku iho pēnei i te tote, te whakamaroke, te whakapūkara, me te paowa, ki ngā huarahi hou pēnei i te whakatio tere, te whakakī i te kēne, te takai korehau, te MAP, me te whakamahi i ngā kai taiao, e tuku ana i ngā otinga e tika ana mō ngā hiahia me ngā āhuatanga motuhake. Ko te wero kei mua ko te whakamahi i ngā hangarau whai hua, e pai ana ki te taiao, e utu tika ana, me te whakarite i te kounga me te haumaru. Mā te tautoko o te auahatanga me te whakatinanatanga o ngā paerewa tika, ka taea te pārekareka ki ngā hua ika me te pupuri i te kounga mai i te awa ki te awa.
