Methylcellulose ndi chowonjezera chowonjezera chakudya. Amapangidwa kuchokera ku cellulose yachilengedwe kudzera mu kusintha kwa mankhwala. Imakhala ndi bandali yabwino, yolumikizira ndi kukula kwamitundu ndipo imagwiritsidwa ntchito kwambiri pa malonda. Monga chinthu chosinthika chosinthika, chitetezo chake cha chakudya chakhala chodekha.
1. Katundu ndi ntchito za methylcellulose
Mapangidwe a masentimita a methylcellulose amatengeraβ-1,4-glucose unit, yomwe imapangidwa ndikusintha magulu ena a hydroxyl ndi magulu a methoxy. Imasungunuka m'madzi ozizira ndipo imatha kupanga gel yosasinthika yomwe ili pansi pa zinthu zina. Ili ndi kukula kwake, emulsization, kuyimitsidwa, kukhazikika komanso zosafunikira zamadzi. Ntchito izi zimapangitsa kuti zikhale zogwiritsidwa ntchito kwambiri mu mkate, makeke, zakumwa, zinthu zamkaka, zakudya zowunda ndi minda ina. Mwachitsanzo, zitha kusintha kapangidwe kake ndikuchedwa kukalamba; Zakudya zoundana, zimatha kukonza zakumwa zakumwazing.
Ngakhale kuti mitundu yosiyanasiyana yosiyanasiyana, methyllulose yokha silinatengeke kapena yopangidwa mthupi la munthu. Pambuyo pakulowetsedwa, amachotsedwa mu thirakiti la m'mimba mu mawonekedwe osawoneka, omwe amachititsa kuti thupi la munthu liziwoneka lopanda malire. Komabe, mawonekedwewa abweretsanso chidwi cha anthu chomwe munthu wa nthawi yayitali angakhudze thanzi.
2. Kuzindikira kwa poizoni ndi chitetezo
Kafukufuku wambiri osokoneza bongo awonetsa kuti methylcluloseoseulose ali ndi zinthu zabwino komanso zoopsa. Zotsatira za mayeso oopsa omwe adawonetsa kuti LD5 M'mayeso oopsa oopsa, makoswe, mbewa ndi nyama zina sizinasonyeze zovuta zina podyetsa nthawi yayitali, kuphatikizapo zoopsa monga carcinogenicity, teratogenicity ndi kubereka.
Kuphatikiza apo, zotsatira za methylclulose pa matumbo aumunthu nthawi zambiri amaphunziridwa kwambiri. Chifukwa sichikugunda ndikulowetsedwa, methylclulose imatha kuwonjezera voliyul yopondapo, kulimbikitsa matumbo am'matumbo, ndipo ali ndi phindu lililonse pakuthamangira. Nthawi yomweyo, sikuti amanjenjemera ndi matumbo, kuchepetsa chiopsezo cha kupindika kapena kupweteka m'mimba.
3. Malamulo ndi miyambo
Kugwiritsa ntchito methylcelulose monga chowonjezera cha chakudya kumayendetsedwa kwambiri padziko lonse lapansi. Malinga ndi kuwunika kwa Komiti Yogwirizana ndi Zowonjezera Zowonjezera Zazakudya (Jeco) pansi pa bungwe la United Nations ndi World Health Organisation (Ndani), osafotokozedwa ", kuwonetsa kuti ndibwino kugwiritsa ntchito mkati mwa Mlingo woyenera.
Ku United States, methylclulose imalembedwa ngati yodziwika bwino ngati yotetezeka (gras) yotetezedwa ndi chakudya cha US ndi mankhwala osokoneza bongo (FDA). Ku European Union, imawerengedwa ngati chakudya chowonjezera cha E461, ndipo kugwiritsa ntchito kwake kwakukulu m'masamba osiyanasiyana kumafotokozedwa. Ku China, kugwiritsa ntchito methylcellulose kumayendetsedwanso ndi "dziko la National Chakudya Chowonjezera Chakudya Chowonjezera" (GB 2760), chomwe chimafuna kuwongolera kwa mlingo molingana ndi mtundu wa chakudya.
4. Malingaliro a chitetezo pamapulogalamu othandiza
Ngakhale chitetezo chonse cha methylcellulose ndi chachikulu, kugwiritsa ntchito chakudya kumafunikirabe kulabadira mfundo zotsatirazi:
Mlingo: Zowonjezera kwambiri zimatha kusintha mawonekedwe a chakudya ndikukhudza mtundu; Nthawi yomweyo, kudya mopitirira muyeso kwa zinthu zokulirazi kungayambitse kutulutsa kapena kufalitsa m'mimba.
Kuchuluka kwa anthu: Kwa anthu omwe ali ndi matumbo ofooka (monga ana okalamba kapena aang'ono), Mlingo waukulu wa methylcllulose angayambitse kudzimbidwa kwanthawi yayitali, motero ayenera kusankhidwa mosamala.
Mogwirizana ndi zosakaniza zina: M'mapanga ena, methyllulose amatha kukhala ndi syrnergist zotsatira ndi zina zowonjezera kapena zosakaniza, komanso zotsatira zawo zofunika kuzilingalira.
5. Chidule ndi Maganizo
Mwambiri,methylcellulose Ndiwowonjezera chakudya chothandiza komanso chothandiza chomwe sichingavulaze kwambiri ku thanzi laumunthu pakugwiritsa ntchito koyenera. Zomwe sizingatheke zimapangitsa kuti zikhale zokhazikika mu thirakiti lazing'ono ndipo limabweretsa zabwino zina. Komabe, kuti titsimikizirenso chitetezo chake pakugwiritsa ntchito kwa nthawi yayitali, ndikofunikira kupitiliza kumvetsera kwa maphunziro oyenera osokoneza bongo komanso deta yofunsira, makamaka zimakhudza anthu apadera.
Ndi chitukuko cha malonda ndi kusintha kwa kufuna kwa ogula kwa chakudya chabwino, kuchuluka kwa methylcellulose kungakulitsidwenso. M'tsogolomu, magwiridwe ochezera ena ayenera kusungidwa pachinthu kuti muwonetsetse kuti chakudya chikhale chofunikira kwambiri.
