Te Tātari i te Pūmautanga o ngā Kakara me ngā Whakarei

Hei tāpiri mahi nui i roto i te hanga kai, ka pā tika te pumau o ngā kakara me ngā mea kakara ki te kounga o te hua me te wheako o te kaiwhakamahi. Ko te pumau o ngā kakara me ngā mea kakara e whakaatahia ana i roto i ngā āhuatanga e rua:

Te pumau o te kakara me te kakara

Ko te pumau o te kakara, te kakara rānei, e pā ana ki te kaha o te kakara, te kakara rānei ki te pupuri i te kakara ōrite mō tētahi wā, i raro i ngā āhuatanga motuhake, me te kore e nui ngā panonitanga. He mea nui tēnei pumau nā te mea ko te kakara te whakaaro tuatahi a ngā kaihoko mō tētahi hua. Ko tētahi rerekētanga kitea o te kakara ka pā tika ki te wheako o te kaihoko. Ko ngā āhuatanga pēnei i te ōwehenga o ngā wāhanga pūngāwerewere, ngā piki me ngā heke o te pāmahana o te taiao, me te pānga ki te hau, ka pā nui ki te pumau o te kakara.

Te Pūmautanga o ngā Āhuatanga Ā-tinana me te Matū

Ko te pumau ā-tinana, ā-matū hoki o ngā kakara me ngā mea kakara e pā ana ki te kore e rerekē ō rātou āhuatanga, ahakoa ko rātou anake, i roto rānei i tētahi reo (pēnei i te hinu, te waipiro, te wai rānei). I te wā e rongoatia ana, e pāngia ana rānei e te wera, te mārama, te hau rānei, ka pāngia pea ngā kakara me ngā mea kakara e te waikura, te pirau, te whakakorikori, te wehenga rānei, ka heke te kounga o te hua. Hei tauira, ko ngā wāhanga kei roto ngā hononga takirua kāore i te mātotoru ka ngāwari ki te waikura i te aroaro o te hāora, ka heke te kakara.

Ngā Take Matua e Pā Ana ki te Pūmautanga

Te pāmahana

Ko te pāmahana tētahi o ngā mea tino nui e pā ana ki te pumau. Hei tauira, 2-Methyltetrahydrofuran-3-one, ki te rongoatia ki te pāmahana rūma mō te wā roa (kaua ki te 2–8°C i tūtohutia), ka puta he kakara kawa nā ngā huringa hanganga. Ka tere ake te whakapūpū me ngā tauhohenga matū o ngā matū waro i roto i ngā kakara me ngā mea kakara i ngā pāmahana teitei, ka whakaiti, ka whakarerekē rānei i ō rātou wāhanga kakara. I tetahi atu taha, ka taea e ngā pāmahana iti te whakapūpū, te wehe rānei i ētahi wāhanga, ka pā ki te ōritetanga.

Pēhanga

I roto i ngā ipu hiri, ka taea e ngā panonitanga pēhanga te arahi ki te ngaronga o ngā wāhanga pūngāwerewere. He tino pāngia ngā kakara e ngā panonitanga pēhanga ina whakatuwheratia te ipu.

Te waikawa me te kawakore

Ka pāngia pea ngā kakara me ngā mea kakara e te waikura, te waikura, ētahi atu tauhohenga matū rānei i roto i ngā taiao waikawa, ka huri hei waipiro me te waikawa i raro i ngā āhuatanga kawakore, ka whakarerekē i ngā āhuatanga kakara taketake.

Wā

Mā te rokiroki roa ka pirau haere, ka taunekeneke rānei ngā wāhanga, inā koa i roto i ngā kakara whakaranu (ngā ranunga o ngā matū kakara), he uaua ake te nuinga o te wā. Hei tauira, ko te parakore o 2,3-hexanedione, i te tīmatanga neke atu i te 98%, ka heke pea ki te 97.7% i muri i ngā marama e toru o te rokiroki (i runga i ngā raraunga whakamātautau). Ko ēnei panoni iti o ngā wāhanga iti i roto i te wā ka pā nui ki te kakara whānui.

Whakataurite: Te Pūmautanga o ngā Kakara Kotahi-Matū me ngā Kakara Whakaranu

He māmā noa iho te pumau o ngā kakara kotahi-pūhui nā te mea he māmā noa iho te hanganga, ā, he māmā ake te matapae me te whakahaere i ā rātou tauhohenga ki ngā āhuatanga taiao. He rerekē, he uaua ake te pumau o ngā kakara whakaranu, nā te mea he maha ngā wāhanga kei roto, ka taunekeneke pea tetahi ki tetahi, ka hanga matū hou, ka whakarerekē rānei i te kakara taketake. Hei tāpiri, me whai whakaaro anō hoki ki te hototahitanga ki te reo (hei tauira, ngā hinu kawe, te wai, ngā emulsifier rānei).

Ngā Whakatau me ngā Taunakitanga

Hei whakarei ake i te pumau o ngā kakara me ngā mea kakara, he mea nui kia whakahaere i ngā āhuatanga taiao pēnei i te pāmahana, te mārama, me te haumākū i te wā e hangaia ana, e whakamahia ana hoki. He mea nui anō hoki te arotau i ngā hanganga hei whakaiti i ngā taunekeneke matū i waenga i ngā wāhanga. Mō te rokiroki, e taunakihia ana kia whakamahia ngā ipu hiri, ātete ki te mārama, me te kore e mau ki ngā matū, me te whakahaere i ngā whakamātautau auau hei aroturuki i ngā āhuatanga ā-tinana me te matū. Mā te whakatinana i ēnei mahi, ka taea te whakanui ake i te mahi a ngā kakara me ngā mea kakara, kia mau tonu ai ngā wheako kounga teitei mō ngā kaihoko.
