Te Konutai Carboxymethyl Cellulose (CMC)He matū whakarerekē te matū i ahu mai i te cellulose taiao, e whakamahia whānuitia ana i roto i ngā ahumahi kai, rongoā me ngā ahumahi matū o ia rā. Ko te CMC kai-papa, hei momo polymer colloid, e mahi ana i te nuinga o te wā ki te whakamātotoru, te whakaū, te pupuri wai, te whakaemulsification me te hanga kiriata i roto i te ahumahi kai. Nā tōna haumaru pai me ōna āhuatanga mahi tino pai, kua riro te CMC hei tētahi o ngā rauemi polysaccharide tino pakari e whakamahia ana i roto i ngā tāpiringa kai.
1. Tātaritanga haumaru o te CMC kai-kounga
He mea hanga te CMC kai-kai mai i te cellulose tipu tūturu hei rauemi mata, ā, ka puta mai ngā hua carboxymethylated mā roto i ngā tauhohenga etherification. He pumau tōna hanganga, ā, kāore e ngāwari te mimiti me te whakapūngao e te tinana tangata, nō reira he tino haumaru ā-tinana. Kua whakaurua e te World Health Organization (WHO) me te Food and Agriculture Organization o te United Nations (FAO) te CMC ki te rārangi o ngā "tāpiri kai haumaru hei whakamahi", ā, kua whakamāramahia hoki e te Codex Alimentarius Commission ngā ture mō tōna parakore me te whānuitanga o te whakamahinga.
Mō ngā rangahau paitini, he maha ngā hua whakamātautau kua whakaatu kāore he paitini nui o te CMC, kāore he mutagenicity, kāore he teratogenicity, ā, kāore hoki i kitea he pānga ā-tinana ki ngā whekau kararehe, tangata rānei. Kāore te CMC e mimitia e te tinana, engari ka tukuna atu i tōna āhua taketake, nō reira kāore e puta he taumahatanga pākia, kāore hoki e kohia he paitini. Kua whakarōpūtia e te FDA o te Hononga o Amerika hei matū GRAS (Generally Recognised As Safe, generally considered safe), e āhei ai te whakamahi whānuitia i roto i te kai.
He tino kaha te whakahaere a te CMC kai-kai i ngā toenga o ngā konganuku taumaha, ngā pūhaumāota me ngā whakarewa waro i te wā e hangaia ana. Ko tōna parakore he mea neke atu i te 99%, ā, kua oti te whakamātautau paerewa akuaku tino kaha. Mena ka whakamahia i roto i te whānuitanga me te horopeta kua whakaritea e te kawanatanga, e te ao whānui rānei, he tino haumaru te kai i te CMC.
2. Ngā āhuatanga mahi o te CMC kai-kounga
2.1. Ngā pānga whakamātotoru me te whakaū
He nui ngā rōpū carboxymethyl me te hydroxyl kei roto i te ngota CMC, ka taea te hanga hononga hauwai kaha ki ngā ngota wai, ā, ka whakaatu i te āhua hydrophilicity me te pupuhi nui. I roto i ngā pūnaha kai, ahakoa he iti te kukū, ka taea e ia te whakanui ake i te matotoru o te pūnaha, te hanga i tētahi hanganga wai ōrite, ā, nā reira ka whakapai ake i te reka me te kakano o te hua. I taua wā, he tino pai te pumau ionic o te CMC, ā, ka taea te pupuri i te pumau matotoru i roto i ngā taiao waikawa, kawakore, tote nui rānei. He maha ngā wā e whakamahia ana i roto i ngā hua miraka, i ngā inu wai hua me ngā mea kakara hei ārai i te wehewehe me te maturuturu.
2.2. Ngā āhuatanga pupuri wai me te ārai i te ua
Ka taea e te CMC te whakakotahi pai me te makuku, ka whakaiti i te hekenga o te makuku me te tio o te kai i te wā e rongoa ana, e tio ana rānei. Hei tauira, i roto i ngā kai tio me ngā kai tunutunu, ka taea e te āhuatanga pupuri wai o te CMC te ārai i te pakaru me te whakapakeke, te whakaroa i te roa o te wā e rongoa ai, me te pupuri i te ngawari me te hou o ngā hua.
2.3. Ngā āhuatanga o te whakaemulsification me te whakatārewatanga
Ka taea e te CMC te hanga i tētahi kiriata viscoelastic i te atanga hinu-wai, hei whakarei ake i te pumau o te pūnaha emulsification me te ārai i te hinu kia kaua e mānu, kia papatahi rānei. Nō reira, he maha ngā wā e whakamahia ana i roto i ngā hua pēnei i te aihikirīmi, ngā ranu huamata, me ngā inu miraka, e mahi tahi ana me ngā emulsifier hei whakatutuki i tētahi kakano pai, pumau hoki.
2.4.. Ngā āhuatanga hanga kiriata me te paninga
He tino pai ngā āhuatanga hanga kiriata o te CMC, ā, ka taea e ia te hanga i tētahi kiriata mārama ki runga i te mata o te kai. E whakamahia ana hei paninga i ngā hua rākau, i ngā monamona, i ngā paura inamata rānei, hei ārai i te makuku, hei ārai i te waikura, hei whakaroa hoki i te pirau. I roto i te paura inu inamata me te paura kakara, ka taea hoki e te CMC te ārai i te piri me te whakapai ake i te wairewatanga.
2.5. Whakapai ake i te reka me te kakano
Ka taea e te CMC te whakapūmau i te kakano o te kai kia maeneene, kia matotoru hoki, ā, ka whakapai ake i ngā āhuatanga rheological o te hua. Hei tauira, i roto i te miraka kawa me te tiēre, ka taea e te CMC te whakanui ake i te mātotoru, te whakapūmau i te hanganga kakano pai, me te whakarei ake i te wheako reka o ngā kaihoko.
3. Ngā mara tono o te CMC kai-kōeke
Kāwai Inu: Ārai i te whakapūpū me te whakarōpūtanga i roto i ngā inu wai hua me ngā inu pūmua, ā, whakapai ake i te rere me te reka.
Ngā hua miraka: Whakamahia ai i roto i te aihikirīmi me te miraka kawa hei whakarei ake i te matotoru me te aukati i te hanganga o te tioata huka, hei whakapai ake i te maeneene o te kounga o te miraka.
Ngā kai tunua: Whakarei ake i te pupuri wai me te pumau o te kakano o te paraoa pokepoke i roto i te taro me ngā keke, ā, ka roa ake te wā ngawari.
Ngā mea kakara me te ranu soya: Ārai i te wehenga o te hinu me te wai, whakarei ake i te kanapa me te piri ki te pakitara.
Ngā monamona me ngā kai inamata: Hei paninga me te ārai i te whakapiripiri, ka whakapai ake i te āhua me te wairewatanga.
CMC kai-whakauruHe polysaccharide taiao haumaru, pono, ā, he tino mahi. Nā ōna āhuatanga whakamātotoru, whakaū, pupuri wai, whakaemulsifying me te hanga kiriata pai rawa atu, ka mau tonu i tētahi tūranga nui i roto i te umanga kai hou. Mai i te tirohanga haumaru, kua manatokohia te CMC e ngā umanga mana maha o te ao, ā, e mōhiotia ana he tāpiringa kai kore-paitini, kore-mate pāwera, ā, he mea whakamahi mō te wā roa. I te mea kei te piki haere tonu te āwangawanga o te tangata mō te kounga me te hauora o te kai, ka whānui ake ngā mara tono o te CMC kai-kounga, ā, ka haere tonu te whakaatu i ōna painga mahi i roto i ngā tapanga ma, ngā kai iti-ngako me ngā hua tipu.
