Carboxymethylcellulose (cmc) ndi gawo losiyanasiyana lomwe limagwiritsidwa ntchito makamaka pamafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala opangira mankhwala, zodzoladzola, ndi kupanga. Zoyimitsa zinthu zina zamafuta ambiri zimapangitsa kuti wothandizila, wokhazikika, omulsifer, ndi zina zambiri. United States Chakudya ndi mankhwala osokoneza bongo (FDA) amatenga gawo lofunikira pakuwongolera chitetezo ndikugwiritsa ntchito mankhwalawa, kuonetsetsa kuti amakwaniritsa zinthu zolimbitsa thupi asanagwiritsidwe ntchito.
Kuzindikira Carboxymethylcellulose (CMC)
Carboxymethylcellulose, nthawi zambiri imafupikitsidwa ngati CMC, ndi yochokera ku cellulose. Cellulose ndiye mafuta ochulukirapo padziko lapansi ndipo amapezeka m'makoma a mitengo, ndikuthandizira. CMC imachokera ku cellulose kudzera mu njira yosinthira mankhwala yomwe imaphatikizapo kuyambitsa magulu a carboxymethyl pamphepete mwa msana wa cellulose. Kusintha kumeneku kumapereka katundu wofunikira ku cmc, kuphatikizapo kusungunuka madzi, mafakisoni, ndi kukhazikika.
Katundu wa Carboxymethylceluloseulose:
Kusungunuka kwamadzi: masentimita amasungunuka m'madzi, ndikupanga yankho lomveka bwino. Katunduyu amapangitsa kuti ikhale yothandiza pamapulogalamu osiyanasiyana pomwe kukulitsa kapena kukhazikika kumafunikira.
Ma Isccess: CMC imawonetsa machitidwe a pseudoplactic, kutanthauza kuti ma viscy amachepetsa pansi pa kupsinjika kukameta ubweya ndikuwonjezeranso pamene nkhawa imachotsedwa. Katunduyu amalola kugwiritsa ntchito kosavuta mu njira monga kupompa, kupopera mbewu mankhwalawa, kapena kutulutsidwa.
Kukhazikika: CMC imapangitsa kukhazikika kwa emulsions ndi kuyimitsidwa, kuletsa zosakaniza kuti ziletse kapena kusuntha pakapita nthawi. Kukhazikika kumeneku ndi kofunikira muzogulitsa monga mavalidwe saladi, zodzoladzola, komanso kuyimitsidwa kwamankhwala.
Kupanga filimu: CMC imatha kupanga mafilimu owonda, osinthika akauma, ndikupangitsa kuti ikhale yothandiza pogwiritsa ntchito mapiritsi kapena makapisozi, komanso popanga mafilimu.
Ntchito za Carboxymethylcelulose
CMC imapeza kugwiritsa ntchito mafakitale osiyanasiyana chifukwa cha zomwe zimachitika. Ntchito zina zofala zimaphatikizapo:
Makampani ogulitsa zakudya: CMC imagwiritsidwa ntchito ngati thicker, kukhazikika, ndi nyimbo m'njira zosiyanasiyana, kuphatikizasungesungunuke, zojambula, zinthu za ayisikilimu, ndi zakumwa. Zimathandizira kukonza kusintha, pakamwa, ndi aluma kukhazikika.
Mankhwala opangira mankhwala: M'mitundu ya mankhwala, cmc imagwiritsidwa ntchito ngati chofunda mu piritsi, wokulirapo pakuyikidwa, komanso wokhazikika mu emulsions. Imapangitsa kugawa kogwiritsa ntchito mosiyanasiyana komanso kumawonjezera kutsatira kuledzera.
Zodzikongoletsera ndi zinthu zosamalira payekha: CMC imagwiritsidwa ntchito pazodzikongoletsera komanso zinthu zosamalira anthu monga zotupa, mafuta, ma shalsister, ndi kukhazikika kwa mawu. Zimathandizira kusasinthika kwazinthu ndikusintha magwiridwe antchito.
Ntchito za mafakitale: CMC imagwiritsidwa ntchito pamakampani osiyanasiyana a mafakitale, yosungira madzi, ndi rheology yosintha zinthu monga zotupa, zomata, komanso madzi obowola.
FDA KUTSOGOLA
Ku United States, FDA imalamulira zowonjezera zowonjezera zakudya, kuphatikizapo zinthu ngati cmc, pansi pa federal chakudya, mankhwala owonjezera (chinthu chowonjezera cha FDa ndikuwonetsetsa kuti) Zowonjezeredwa ku chakudya ndizotetezeka pakudya ndikukwaniritsa chofuna chothandiza.
Kuvomerezedwa ndi FDA kwa zowonjezera zakudya nthawi zambiri kumaphatikizapo kutsatira:
Kuwunika kwa Chitetezo: Wopanga kapena wopereka zakudya zowonjezera za chakudya ndi udindo wochititsa maphunziro achitetezo kuti awonetsetse kuti chinthucho ndichotetezeka pakugwiritsa ntchito kwake. Kafukufuku amenewa ndi kuphatikiza zoopsa, kafukufuku pa kagayidwe kake, komanso kuchuluka kwake.
Kugonjera kwa pempho lowonjezera chakudya: Wopanga amapereka pempho lowonjezera chakudya (fup) kupita ku FDA, kupereka chidziwitso chazomwezo, kapangidwe kake, kugwiritsa ntchito deta yazowonjezera. Pempho liyeneranso kuphatikizira zomwe zalembedwa.
FDA NTHAWI YOTHANDIZA: FDA imayesa deta yachitetezo yomwe idaperekedwa mu nsalu kuti mudziwe ngati zowonjezera ndizotetezeka pakugwiritsa ntchito zomwe wakugwiritsa ntchito. Ndemanga iyi imaphatikizapo kuwunika koopsa kwa thanzi la anthu, kuphatikizapo kufalikira ndi zovuta zilizonse zomwe zimachitika.
Kufalitsa kwa malamulo omwe akufuna: Bukuli limalola kuyamizidwa ndi anthu pagulu.
Kulamulira komaliza: Mukaganizira ndemanga zapagulu komanso zambiri, FDA imapereka lamulo lomaliza lovomereza kapena kukana kugwiritsa ntchito zowonjezera pachakudya. Ngati kuvomerezedwa, lamulo lomaliza limakhazikitsa zofunikira zina, kuphatikizapo zoperewera zilizonse, zokhudzana ndi malamulo, kapena kulembera zofunika.
Carboxymethylcellulose ndi FDA Kuvomereza
Carboxymethylcellulose ali ndi mbiri yayitali yogwiritsa ntchito malonda ndi magawo ena, ndipo nthawi zambiri amadziwika kuti ndi otetezeka (gras) pazomwe amagwiritsa ntchito mogwirizana ndi zomwe amapanga. FDA yatulutsa malamulo ndi madongosolo olamulira kugwiritsa ntchito cmc mu chakudya ndi mankhwala opanga mankhwala.
FDA lamulo la Carboxymethylcelulose:
Zowonjezera Zowonjezera: Carboxymethylcelulose imalembedwa ngati chakudya chovomerezeka muudindo wa feduro (CFR) pansi pa Gawo 176.Code 8672, ndi malamulo omwe adafotokozedwa kuti agwiritse ntchito m'magulu osiyanasiyana. Malamulowa amatchulanso kuchuluka kwa masentimita osiyanasiyana pazakudya komanso zofunika zina.
Kugwiritsa ntchito mankhwala: mu mankhwala opangira mankhwala, CMC imagwiritsidwa ntchito ngati chosagwira ntchito pogwiritsa ntchito mankhwala osokoneza bongo, ndipo kugwiritsa ntchito kwake kumayendetsedwa pansi pa malo a FDA kuti mudziwe mankhwala osokoneza bongo. Opanga ayenera kuonetsetsa kuti masentimita amakumana ndi zomwe zafotokozedwa ku United States Farmacapea (USP) kapena yoyenererana.
Kulemba Zofunikira: Zinthu Zomwe Zimakhala Ndi CMC Monga gawo liyenera kutsatira malamulo a FDA ponena za kulemba, kuphatikizapo mindandanda yolondola yophatikizira kapena kulembedwa koyenera kwa khungu.
Carboxymethylcellulose (cmc) imagwiritsidwa ntchito kwambiri ndi ntchito zosiyanasiyana mu Chakudya, mankhwala opangira mankhwala, zodzikongoletsera, ndi mafakitale. Malo ake apadera amapangitsa kukhala wofunika kwambiri ngati wotchinga, wokhazikika, emulsiferi, ndi binde mu zinthu zosiyanasiyana. FDA imachita mbali yofunika kwambiri pakuwongolera chitetezo ndikugwiritsa ntchito cmc ndi zina zowonjezera zowonjezera, onetsetsani kuti akumana ndi miyezo yokhazikika isanayambe kugwiritsa ntchito mankhwala ogula. CMC imalembedwa ngati chakudya chololedwa ndi FDA, ndipo kugwiritsa ntchito kwake kumayendetsedwa ndi malamulo ndi malangizo omwe adafotokozedwa muudindo 21 wa malamulo a federal. Opanga ndi othandizira omwe ali ndi masentimita ayenera kutsatira mfundozi, kuphatikizapo kuyerekezera chitetezo, kulembera zofunika, komanso zochitika zogwiritsidwa ntchito, kuonetsetsa kuti zinthu zawo zitheke.
