HPMC (Haidroksiporoporo Mētara Hūrouro)meHPC (Haidroksiporoporo Pūtau)He matūriki cellulose ēnei e rua, e whakamahia whānuitia ana i roto i ngā ahumahi rongoā, kai, hanga me te whakapaipai. Ahakoa he rite tonu ētahi āhuatanga o ēnei mea e rua, he mārama kei te rerekē te hanganga matū, ngā āhuatanga ā-tinana me te matū, te wairewa me ngā wāhi tono.
1. Hanganga matū me ngā āhuatanga
Ka hangaia te HPMC mā te methylation me te hydroxypropylation o te cellulose tūturu, ā, kei roto i te ngota ngā rōpū methoxy (–OCH₃) me te hydroxypropoxy (–OCH₂CHOHCH₃).
Ka whiwhihia te HPC mā te hydroxypropylation o te cellulose, ā, ko tōna rōpū mahi matua ko te hydroxypropoxy (–OCH₂CHOHCH₃), me te kore he methoxy.
Nā te mea kei roto i te HPMC tētahi atu rōpū methoxy i te HPC, he paku wai-whakahē ake te HPMC, engari he wai-whakahē ake te HPC. Hei tāpiri, he teitei ake te taumaha ngota o te HPMC, engari ka taea te whakahaere ngāwari ake i te taumaha ngota o te HPC, ka pā ki te wairewa me ngā āhuatanga matotoru o te rua.
2. Te wairewatanga wai me ngā āhuatanga wairewatanga
Ka rewa te HPMC ki te wai matao hei hanga i tētahi wairewa korori mārama, engari kāore e rewa ki te wai wera. Nō reira, me rewa, me whakamarara rānei te HPMC mā te whakamahi i ngā tikanga motuhake i roto i ētahi mahi.
He pai te wairewatanga o te HPC ki te wai, ā, ka taea te rewa ki te wai matao me ētahi whakarewa waro, pērā i te etanoru, te methanol, me ētahi atu, ā, he pai hoki ōna āhuatanga whakamātotoru me te hanga kiriata.
He āhuatanga thermogel tō te HPMC. Ina piki te pāmahana, ka wehe pea te otinga i ngā āhua rerekē, engari ko te HPC ia kāore e hanga he thermogel, nō reira he pai ake te pumau o te HPC i ngā taiao pāmahana teitei.
3. Te matotoru me ngā āhuatanga rheological
He nui ake te matotoru o te HPMC, ā, e whakamahia ana hei whakamātotoru, hei whakaū, hei hanga kiriata hoki. He tata ake ōna āhuatanga rheological i roto i te wairewa ki ngā wai rūpahu.
He iti ake te matotoru o te HPC, ā, he pai ake mō ngā whakatakotoranga e hiahia ana kia pai ake te rere, pērā i ngā rongoā ā-waha me ngā rauemi paninga.
4. Ngā āpure tono
Nā te rerekētanga o ngā āhuatanga ā-tinana me te matū i waenga i te HPMC me te HPC, he rerekē ā rāua mahi i roto i ngā ahumahi me ngā hua rerekē:
Ahumahi rongoā
Ko te HPMC te nuinga o te wā e whakamahia ana hei here, hei rauemi tuku-roa, hei rauemi paninga kiriata mō ngā papa rongoā, hei wāhanga anga hoki mō ngā kāpūru tuwhera. Nā tōna āhuatanga hanga kiriata pai me te wairewatanga ki te wai, he mea pai hei tāpiri mō ngā whakaritenga tuku-roa.
Ko te HPC te mea e whakamahia nuitia ana hei whakarewa, hei here, hei whakarewa, hei rauemi piri koiora hoki mō ngā papa, ā, he pai hoki mō te whakapai ake i te wairewatanga me te waatea koiora o ngā rongoā. Hei tāpiri, he whānui ake te whakamahinga o te HPC i roto i te hangarau whakaputa rewa wera i te HPMC.
Ahumahi kai
Ka taea te whakamahi i te HPMC hei whakamātotoru kai, hei whakaemulsifier, hei whakaū, me te whakaū emulsifier mō te kirīmi kore-miraka.
Ko te HPC te mea nui e whakamahia ana hei whakamātotoru kai, hei whakaemulsifier, hei whakapai ake hoki, ā, he pai mō ngā kai kore huka me ngā kai iti-kaiora.
Ngā mea whakapaipai me te tiaki whaiaro
Ka taea te whakamahi i te HPMC i roto i ngā hua tiaki kiri me ngā hopi horoi hei whakaū emulsifier.
He pai ake te HPC mō ngā hua tiaki makawe, ngā whakamakuku me ngā hua tiaki kanohi nā te mea he pai tōna wairewatanga ki te wai me te hinu whakahinuhinu.
Ngā rauemi hanga whare
He wāhanga nui te HPMC i roto i ngā paninga hoahoanga, ngā moata, me ngā paura putty, e whai wāhi ana ki te whakamātotoru, te pupuri wai me te whakarei ake i te piri.
Kāore i te tino whakamahia te HPC i roto i te umanga hanga, engari ka taea te whakamahi i roto i ngā paninga me ngā piripiri wairewa-wai motuhake.
5. Te tiaki taiao me te haumaru
I ahu mai te HPMC me te HPC i te cellulose tūturu, ā, he pai te pirau me te haumaru. E kiia ana te HPMC he kore paitini, kāore hoki e whakapataritari, engari e whakamahia whānuitia ana te HPC i roto i te kai me te rongoā, e tutuki ana i ngā whakaritenga haumaru o te FDA (US Food and Drug Administration) me ētahi atu paerewa o te ao.
6. Ngā whakaaro kōwhiringa
Mena e hiahiatia ana he matotoru ake me ngā āhuatanga hanga kiriata, he pai te HPMC, pērā i te paninga papa, ngā paninga hoahoanga me ētahi atu tono.
Mena e hiahiatia ana he wairewatanga pai ake me te hototahitanga koiora, he pai te HPC, pērā i ngā rongoā ā-waha, ngā wāhanga whakaputa wera rewa, me ētahi atu.
HPMCmeHPCHe mea nui ngā matū e rua i ahu mai i te cellulose, he rerekē te hanganga matū, te wairewatanga, me ngā wāhi tono. He pai ake te HPMC mō ngā tono matotoru teitei, hanga-kiri wera pērā i te paninga papa me ngā rauemi hanga, ko te HPC ia he pai ake mō ngā whakaritenga ā-waha, ngā mea whakapaipai me ngā mea whakapai kai nā te mea he pai te wairewatanga ki te wai me te matotoru iti. E ai ki ngā hiahia motuhake, mā te whiriwhiri i te rauemi tika ka taea te whakapai ake i te mahi me te pumau o te hua.
