Ko te Carboxymethyl cellulose (CMC) he pūmua wairewa-wai i ahu mai i te cellulose, koinei te pūmua waro tino nui rawa atu i runga i te Ao. Ka puta te CMC mā te whakarerekētanga matū o te cellulose, mai i te penupenu rakau, i ngā miro rānei. He whānuitia te whakamahinga i roto i te whānuitanga o ngā tono nā ōna āhuatanga ahurei, tae atu ki tōna kaha ki te hanga i ngā otinga matotoru me ngā kirikiri, tōna kaha ki te here i te wai, me tōna pirau koiora.
Hanganga Matū me te Whakaputa
Ko te hanganga matū o te CMC he mea hanga mai i ngā tuara cellulose me ngā rōpū carboxymethyl (-CH2-COOH) e piri ana ki ētahi o ngā rōpū hydroxyl (-OH) i runga i ngā monomer glucose. Ko tēnei tukanga whakakapinga ko te rongoā i te cellulose ki te waikawa chloroacetic i roto i te reo kawakore, ka hua ake ai te hanganga o te cellulose carboxymethyl konutai. Ko te taumata o te whakakapinga (DS) e pā ana ki te maha toharite o ngā rōpū hydroxyl mō ia waeine glucose kua whakakapia e ngā rōpū carboxymethyl, me te DS o te 0.4 ki te 1.4 te mea noa mō te nuinga o ngā tono.
Ko te tukanga whakaputa o te CMC he maha ngā taahiraa:
Te Whakapūngao: Ka rongoatia te cellulose ki tētahi turanga kaha, ko te nuinga he konutai hauwai, hei hanga i te cellulose kawakore.
Whakapūtanga: Kātahi ka tauhohehia te cellulose alkali ki te waikawa chloroacetic, ka hua ake te whakakapinga o ngā rōpū hydroxyl e ngā rōpū carboxymethyl.
Te Whakama: Ka horoia te CMC mata, ka whakamāoritia hei tango i ngā hua taha me ngā matū taikaha.
Te Whakamaroke me te Mira: Ka whakamarokehia te CMC kua parakorehia, ka mirahia kia whiwhi ai i te rahi matūriki e hiahiatia ana.
Ngā Āhuatanga
E mōhiotia ana te CMC mō ōna āhuatanga tino pai, e whai hua ai i roto i ngā momo ahumahi:
Wairewatanga i te Wai: Ka tere te rewa o te CMC ki te wai, ka puta he wairewa mārama, matotoru.
Te Whakarerekētanga o te Mātotoru: Ka taea te whakarerekē i te mātotoru o ngā otinga CMC mā te whakarerekē i te kukū me te taumaha ngota, kia whai hua ai mō te whakamātotoru me te whakau.
Te Hanganga Kiriata: Ka taea te hanga i ngā kiriata kaha, ngāwari ina whakamaroketia mai i te wairewa.
Ngā Āhuatanga Piri: He pai ngā āhuatanga piri o te CMC, he mea whai hua i roto i ngā tono pēnei i ngā piripiri me ngā paninga.
Pirau: Nā te mea i ahu mai i te cellulose tūturu, ka pirau te CMC, ā, he pai mō te taiao.
Ahumahi Kai
He whānuitia te whakamahinga o te CMC hei tāpiri kai (E466) nā tōna kaha ki te whakarerekē i te matotoru me te whakau i ngā wairewa i roto i ngā momo kai. He mea whakamātotoru, he mea whakau, he mea whakaemulsifier hoki i roto i ngā hua pēnei i te aihikirīmi, ngā hua miraka, ngā mea tunu taro, me ngā ranu huamata. Hei tauira, i roto i te aihikirīmi, ka āwhina te CMC ki te aukati i te hanganga o ngā tioata tio, ka hua ake he kakano maeneene ake.
Ngā Rongoā me ngā Mea Whakapaipai
I roto i te umanga rongoā, ka whakamahia te CMC hei here i roto i ngā papa, hei whakarewa, hei whakanui i te matotoru i roto i ngā whakatārewatanga me ngā whakamomona. Ka mahi anō hoki hei whakaū i roto i ngā hinu, ngā kirīmi, me ngā tiēre i roto i te umanga whakapaipai. Nā tōna āhua kore-paitini, kore-whakariri hoki, he pai mō te whakamahi i roto i ēnei hua.
Pepa me ngā Kakahu
E whakamahia ana te CMC i roto i te umanga pepa hei taputapu rahi hei whakapai ake i te kaha me te āheinga tā o te pepa. I roto i ngā kakahu, ka whakamahia hei taputapu whakamātotoru i roto i ngā tukanga tae, hei wāhanga hoki i roto i ngā whakapiri tā kakahu, hei whakarei ake i te ōritetanga me te kounga o ngā tānga.
Ngā Hopi me ngā Ākena Horoi
I roto i ngā hopi horoi, ka mahi te CMC hei mea whakatārewatanga oneone, hei ārai i te paru kei rewa anō ki runga i ngā kakahu i te wā e horoi ana. Ka whakapai ake hoki i te mahi a ngā hopi horoi wai mā te whakanui ake i tōna matotoru me te pumau.
Te Keri Hinu me te Maina
E whakamahia ana te CMC i roto i ngā wai keri hinu hei whakahaere i te matotoru, hei whakarerekē hoki i te rheology hei pupuri i te pumau o te paru keri, hei ārai i te hinga o ngā poka keri, hei whakahaere hoki i te tango i ngā tapahi. I roto i te keri, e whakamahia ana hei kaihopu whakamātao me te whakapūpū wai.
Hanganga me ngā Uku
I roto i te umanga hanga, ka whakamahia te CMC i roto i ngā hanganga sima me te moata hei whakapai ake i te pupuri wai me te ngāwari o te mahi. I roto i ngā uku, ka mahi ia hei here me te whakapūmau i roto i ngā whakapiri uku, hei whakapai ake i ōna āhuatanga whakapūmau me te whakamaroke.
Ngā Whakaaroaro mō te Taiao me te Haumaru
E whakaarohia ana te CMC he haumaru (GRAS) e ngā mana whakahaere pēnei i te FDA. Kāore he paitini, kāore e pāwera, ā, ka pirau, kia pai ai te taiao. Heoi, ko te tukanga whakaputa he matū me tino tupato ki te whakahaere kia kore ai e poke te taiao. He mea nui te whakakorenga me te maimoatanga tika o ngā para hei whakaiti i te pānga ki te taiao.
Ngā Auahatanga me ngā Aronga o te Ao
Ko ngā whanaketanga hou o te CMC ko te whanaketanga o te CMC kua whakarerekētia me ngā āhuatanga whakarei ake mō ngā tono motuhake. Hei tauira, ka taea e te CMC me te taumaha ngota ira kua whakaritea me te taumata whakakapinga te tuku i te mahi pai ake i roto i ngā pūnaha tuku rongoā, i te mea rānei he rauemi takai koiora. Hei tāpiri, kei te tūhuratia tonutia te whakamahinga o te CMC i roto i ngā wāhanga hou pēnei i te hangarau kiko me te tānga koiora, ka tino whai hua pea tōna hototahitanga koiora me ōna pūkenga hanga-ira.
He rauemi maha ngā whakamahinga, he rauemi whai hua hoki te carboxymethyl cellulose, he whānuitia ngā whakamahinga puta noa i ngā ahumahi maha. Ko ōna āhuatanga ahurei, tae atu ki te wairewatanga i roto i te wai, te whakarerekētanga matotoru, me te pirau, he mea nui ki roto i ngā hua maha. Nā te haere tonu o te whanaketanga me te whakarerekētanga o tana hanga, kua rite te CMC ki te whai wāhi nui haere i roto i ngā mara tuku iho me ngā mara hou, e whai wāhi ana ki te ahunga whakamua hangarau me ngā mahi pumau.
