Mā te papa uku kua whakapūkaratia i hangaia me ngā whakapūkaratia kounga teitei ka māmā ake te hanga i te papaanga. Kāore he take ki te whakamahana i te uku ki te pāmahana teitei o te 170~180°C i mua i te whakamahinga. Kāore e hiahiatia kia whakamarokehia, kia whakamahanahia hoki ngā rauemi kohuke pēnei i te onepu me te kirikiri, ka taea te penapena i te nui o te wahie me te kaha wera. Nā te mea he pai te mahi a te whakapūkaratia uku, ka taea te tohatoha ōrite ki runga i te mata o te konganuku, ā, he pai te piri ki a ia, nō reira ka taea te penapena i te nui o te uku, te whakangawari i ngā tukanga hanga, te whakapai ake i ngā āhuatanga hanga, me te whakaiti i te parahanga ki te taiao huri noa. Nā ēnei painga, ehara i te mea he pai anake te uku kua whakapūkaratia mō te whakatakoto i ngā rori, engari mō te tiaki pari o ngā pari whakakī, te ārai wai i ngā tuanui me ngā ana o te whare, te ārai waikura o te mata o ngā rauemi whakarewa, te whakapai ake i te oneone ahuwhenua me te hauora o ngā tipu, te moenga ara whānui o ngā rēriwe, te whakapūmau i te onepu koraha, me ētahi atu. He whānui te whakamahinga i roto i te maha o ngā kaupapa. Nā te mea kāore e taea e te uku kua whakapūkaratia te whakapai ake i te hangarau hanga o te uku wera anake, engari ka whakawhānui ake hoki i te whānuitanga o te tono o te uku, kua tere te whanaketanga o te uku kua whakapūkaratia.

He momo matū horoi te emulsifier uku. Ko tōna hanganga matū he rōpū lipophilic me hydrophilic. Ka taea te mimiti i te hononga i waenga i ngā matūriki uku me te wai, ā, ka tino whakaiti i te kaha kore utu o te hononga i waenga i te uku me te wai, ka waiho hei matū horoi e hanga ana i te emulsion ōrite me te pumau.

He matū te matū horoi wai ka taea te whakaiti i te taumahatanga o te mata o te wai ina tāpirihia he iti noa, ā, ka taea te whakarerekē nui i ngā āhuatanga o te atanga me te āhua o te pūnaha, ā, ka puta ko te whakamakuku, te whakaemulsification, te pahuka, te horoi, me te horapa. , te ārai-static, te whakahinuhinu, te whakarewa me te maha atu o ngā mahi hei whakatutuki i ngā whakaritenga o ngā tono mahi.

Ahakoa te momo matū horoi, ko tōna ngota he mea tito tonu mai i tētahi mekameka warowaihā kore-polar, hydrophobic me lipophilic me tētahi rōpū polar, oleophobic me hydrophilic. He maha ngā wā ka noho ēnei wāhanga e rua ki runga i te mata. Ko ngā pito e rua o te ngota matū hohe he hanganga kore-taurite. Nō reira, ko te hanganga ngota o te matū horoi he ngota amphiphilic he lipophilic me hydrophilic, ā, he mahi hono i ngā āhua hinu me te wai.

Ina nui ake ngā matū horoi i tētahi kukū i roto i te wai (kukū micelle nui), ka taea e rātou te hanga micelle mā te pānga hydrophobic. Ko te horopeta emulsifier tino pai mō te uku emulsified he nui ake i te kukū micelle nui.
