Ngā rerekētanga i waenga i te Wāhanga, te Hauwai me te Whakapūtanga o ngā hinu me ngā ngako.
Ko te wehewehenga, te hauwai, me te whakahāngaitanga ngā hangarau matua e toru mō te whakarerekē i ngā āhuatanga ā-tinana me te matū o ngā hinu me ngā ngako kia tutuki ai ngā hiahia kanorau o te umanga kai. Ko te rerekētanga matua i waenganui i a rātou kei roto i ngā mātāpono motuhake e whakamahia ana e rātou hei whakarerekē i ngā āhuatanga o ngā hinu me ngā ngako. Kei raro nei, ka whakaatuhia he whakataurite mārama o ō rātou rerekētanga mā te ripanga me ngā whakamārama taipitopito.
Whakarāpopototanga o ngā Rerekētanga Matua
| Taonga | Te wehewehenga | Te whakahāoratanga | Te whakapūngao |
| Taiao | Te huringa ā-tinana | Huringa matū | Huringa matū |
| Kaupapa | Te wehenga i runga i ngā rerekētanga ira rewa o ngā momo triglyceride mā te whakamatao, te whakatioatatanga, me te tātari. | Te tāpiri i te hauwai ki ngā hononga takirua o ngā waikawa ngako kore kukū i raro i te mahi a tētahi whakakorikori. | Te whakarerekē matapōkere, te ahunga rānei o ngā waikawa ngako i runga i te tuara o te glycerol i raro i te mahi a tētahi whakakorikori, a tētahi whākōkī rānei. |
| Whāinga | Te wehewehe i ngā hinu kia rua ngā wāhanga rewa teitei (stearin) me ngā wāhanga rewa iti (olein). | Te whakanui ake i te ira rewa o ngā hinu hei whakaputa ke i te āhua wai ki te āhua totoka-haurua, totoka rānei; te whakarei ake i te pumau waikura. | Te whakarerekē i ngā āhuatanga tioata me te kirihou o ngā hinu, me te kore e whakarerekē i te hanganga o te waikawa ngako. |
| Pānga ki ngā Waikawa Ngako | Kāore he huringa i te hanganga matū o ngā waikawa ngako. | Te panonitanga o te hanganga matū o ngā waikawa ngako: ngā waikawa ngako kore kukū → ngā waikawa ngako kukū; ka puta pea ngā waikawa ngako whakawhiti. | Kāore he huringa i roto i te hanganga matū o ia waikawa ngako, engari he huringa i roto i tō rātou tohatoha i runga i te tuara o te glycerol. |
| Ngā Āhuatanga o te Hua | Tikina kia rua, neke atu rānei ngā hua he rerekē ngā āhuatanga ā-tinana (hei tauira, te olein nikau me te stearin nikau mai i te hinu nikau). | Whiwhi hinu kua whakahauwaitia ki te hauwai, he mārō ake te kakano, ā, he pai ake te pumau. | Whiwhi hinu he āhua hou, he kakano hou hoki hei rewa, pērā i te pata kore-ngako whakawhiti me te hinu whakapoto. |
| Te Whakataurite Māmā | He rite ki te waiho i te hinu ki waho i te hotoke, te wehe i te hinu wai i te wāhanga totoka. | Pērā i te whakapakari i ngā ngota pūmau kia "totoka" ake ai, kia "pūmau ai". | He rite ki te whakaranu i tētahi kete kāri (ngā waikawa ngako) hei whiwhi i tētahi ringa hou (hinu hou). |
Whakamārama Taipitopito
1. Te Wehewehenga
• Whakaaro matua: Te wehenga, ehara i te whakarerekētanga.
• Tukanga: Whakamahanatia mārire te hinu kia rewa, kātahi ka whakamatao mārire i tētahi pāmahana kua whakaritea. Ka tio tuatahi ngā triglycerides he teitei ake ngā ira rewa, ka hanga he matūriki totoka. Kātahi ka taea te wehe i ēnei tioata totoka (stearin) mai i te hinu wai tonu (olein) mā te tātari, te centrifugation rānei.
• Ngā tauira tono:
o Te wehewehenga o te hinu nikau: Koinei te whakamahinga tino noa o te hangarau wehewehenga. Ka taea te wehewehe i te hinu nikau hei whiwhi i te olein nikau (e whakamahia ana mō te hinu tunu kai, te hinu parai) me te stearin nikau (e whakamahia ana mō te pata, te hinu whakapoto, me ngā ngako reka).
o Te wehewehenga pata: Ka puta he ngako pata parakore ake, e whakamahia ana mō te hanga keke kounga teitei.
• Ngā Painga: He tukanga ā-tinana parakore, kāore he huringa matū i whakaurua, kāore he matū tauhohenga, ā, he mea taiao te hua.
2. Te Whakahāoratanga
• Whakaaro matua: Tāpirihia te hauwai kia "mārō ake" te hinu, kia "pūmau ake".
• Tukanga: I raro i te pāmahana teitei, te pēhanga teitei, me te aroaro o tētahi whakakorikori konganuku (te nuinga he nikara), ka tukuna te hau hauwai ki roto i te hinu wai. Ka tāpirihia e te hauwai ngā hononga takirua i roto i ngā mekameka waikawa ngako kore-māku, ka whakaitihia, ka whakakorea rānei ngā hononga takirua.
o Te hauwaitanga wāhanga: Kāore ngā hononga takirua i tino mākū, ā, he nui ngā waikawa ngako whakawhiti ka puta i tēnei tukanga. Nā te mea he kino ki te hauora o ngā waikawa ngako whakawhiti, kua rāhuitia i roto i te maha o ngā whenua me ngā rohe.
o Te whakapūngao hauwai katoa: Kua tata te whakapūngao o ngā hononga takirua, ā, ko te nuinga ka puta ko ngā waikawa ngako kukū (waikawa stearic), me te kore rawa he waikawa ngako trans. He tino mārō, he pakarukaru hoki ngā hinu kua whakapūngao hauwai katoa, ā, me whakaranu ki te hinu wai, me whakatikatika rānei mā te whakawhiti ester hei whakarerekē i ō rātou āhuatanga.
• Ngā tauira tono:
o Te hanga whakapoto me te pata: Te whakaputa i te hinu pīni soya wai, te hinu rēpī, me ētahi atu hei āhua totoka mō te tunu me te pani.
Te whakapai ake i te pumau o te hinu: Ka roa ake te ora o te hinu parai me ngā kai kei roto te hinu.
• Ngā Huakore: Ka whakaputa i ngā waikawa ngako trans kino (te hauwaitanga wāhanga) ka ngaro ngā waikawa ngako nui.
3. Te Whakawhitiwhitinga o Ētera
• Whakaaro matua: "Te whakakorikori", te whakarerekē i te hanganga o ngā triglycerides.
• Tukanga: I raro i te mahi a te matū whakakorikori (pērā i te konutai methoxide) te lipase rānei, ka "wehewehea" ngā glycerides waikawa ngako i roto i ngā ngota hinu, kātahi ka honoa matapōkeretia, ka honoa rānei ngā waikawa ngako ki te tuara o te glycerol hei hanga i ngā ngota triglyceride hou.
o Whakawhitinga ester matapōkere: Ka whakaritea matapōkeretia ngā waikawa ngako i waenga i ngā ngota katoa.
o Whakawhitinga ester whai mana: I raro i ngā āhuatanga motuhake (pēnei i te pāmahana whakahaeretia), ka anga te tukanga whakaritenga anō ki te ahunga e hiahiatia ana.
• Ngā tauira tono:
o Te hanga hinu whakapoto kore-ngako me te pata: Koinei te whakamahinga hou tino nui o te whakawhiti ester. Mā te mahi whakawhiti ester i waenga i te stearin kua whakahauwaitia katoatia (kaore he waikawa trans) me te hinu wai, ka taea te whiwhi i te ngako kirihou me te kakano tino pai, me te kore he waikawa ngako trans.
Te whakapai ake i te hototahitanga o ngā whakakapinga pata koko.
o Te whakarerekē i te hanganga tioata o te hinu poaka me te pata hei whakapai ake i te mahi tunu.
• Ngā Painga: Ka taea te whakarerekē nui i ngā āhuatanga ā-tinana o ngā hinu me te kore e whakaputa i ngā waikawa ngako trans, ka waiho hei huarahi kē atu ki te hangarau hauwai wāhanga. Whakarāpopototanga
Ki te hiahia koe ki te wehewehe i te hinu kia rerekē ngā wāhanga me ngā ira rewa, whakamahia te whakawehenga. Ki te hiahia koe ki te whakapakeke me te pumau ake i te hinu wai, ka whakamahia te whakahauwai i ngā tikanga tuku iho, engari kia tūpato ki te take o ngā waikawa ngako trans. Ki te hiahia koe ki te whakatika i te pakeke, te kakano me te kirihou o te hinu me te kore e whakamahi i te whakahauwai, ka taea ai te whakaputa i ngā waikawa ngako trans, ko te whakahauwai i te hinu te whiringa pai rawa atu. I roto i te umanga hinu hou, he maha ngā wā ka honoa ēnei tikanga e toru hei whakaputa i ngā hua hinu mahi e tutuki ai ngā hiahia motuhake.
