Makapisozi a mbewu omwe amagwiritsidwa ntchito muzopanga zathu amapangidwa ndi hydroxypropylmethylcellulose (HPMC), yomwe imadziwikanso kuti hydroxypropylmethylcellulose. Tsopano, m'mbuyomu, zinali zotheka kundandalika izi pa lebulo:
Zosakaniza zina:makapisozi a zomera (zomera zamtundu ndi madzi)
Koma kenako a FDA adasintha malamulo olembera kuti zipewa zamasamba zizilembedwa ngati hydroxypropyl methylcellulose kapena hydroxypropyl methylcellulose.
Choncho, ziyenera kudziwidwa poyamba kuti hydroxypropyl methylcellulose phthalate (HPMCP) ndi chinthu chosiyana ndi HPMC yolunjika (hydroxypropyl methylcellulose kapena hydroxypropyl methylcellulose). Inde, mawu amenewa amabweretsa kusiyana kwakukulu.
Malinga ndi tebulo lapadera la wopanga zipewa zamasamba:
HPMC ndi chomera chomwe ndi mtundu woyeretsedwa wa cellulose wotengedwa ku zamkati zamatabwa. Malinga ndi Annex I ya EU Regulation No. 1169/2011 popereka chidziwitso chazakudya kwa ogula, HPMC imatchedwa "fiber" ndipo imatanthauzidwa ngati polima wamadzi a carbon omwe ali ndi mayunitsi atatu kapena kupitilira apo, omwe samagayidwa kapena kulowetsedwa mu matumbo aang'ono amunthu.
Komabe, njira zamakono zoyezera ma labotale a fiber m'zakudya, monga AOAC 985.29, sizizindikira molondola kuti HPMC ndi fiber. Komabe, HPMC ndi edible carbohydrate polima, ulusi wopatsa thanzi wokhala ndi zotsatira zopindulitsa za thupi, zomwe zavomerezedwa kwambiri ndi umboni wa sayansi, motero zitha kulengezedwa mwaufulu.
Kwa iwo omwe sanaphunzire kwambiri umagwirira
Cellulose ndi unyolo wopangidwa ndi mpweya, haidrojeni, ndi mpweya, womwe umapangidwa ndi mazana mpaka masauzande a unyolo wa kaboni, haidrojeni, ndi mpweya pamodzi.
Hydroxyl - zikutanthauza kuti pali mpweya ndi haidrojeni zolumikizidwa penapake pa unyolo wa cellulose, osati haidrojeni.
Propyl - amatanthauza kuti pali unyolo wam'mbali pamalo enaake pa unyolo, pomwe maatomu atatu a kaboni amazunguliridwa ndi haidrojeni.
Methyl - Mofanana ndi propyl, koma osati ma carbons atatu, koma imodzi yokha.
Ikani zinthu zinayi izi pamodzi ndipo mudzapeza=hydroxypropyl methylcellulose
Pofuna kufufuza mosamala chidziwitsochi ndikuwonetsetsa kuti palibe zomwe zanyalanyazidwa kapena zokongoletsedwa, ndinayang'ana ngati Dr. Joseph Mercola (dokotala weniweni wokhala ndi ofufuza anthawi zonse) adalemba nkhani za hydroxypropyl methylcellulose. Ayi. Kenako ndidayang'ana ma supplements ake kuti ndiwone zomwe makapisozi ake adapangidwa. Inde, adalembedwa pansi pa 'Zosakaniza Zina: Hydroxypropylmethylcellulose'.
Kotero ine ndikuganiza ife tikhoza kunena motsimikiza kuti mfundo yaikulu ndi yakuti hydroxypropyl methylcellulose ndi chakudya chochokera ku zomera.
Chigawo chimodzi chomwe chimapezeka nthawi zambiri muzowonjezera zathu ndi hydroxypropyl methylcellulose, yomwe imagwiritsidwa ntchito popanga makapisozi.
Hydroxypropylmethylcellulose nthawi zambiri imachokera ku cellulose ya zomera, yomwe ndi chakudya chomwe chimapezeka m'makoma a maselo a zomera. Pawiri yeniyeniyi imagwiritsidwa ntchito kwambiri popanga makapisozi amasamba.
Hydroxypropylmethylcellulose nthawi zambiri imawoneka ngati mawonekedwe a hydroxypropylmethylcellulose kapena HPMC pamndandanda wazinthu, wofanana ndi "ufa wamatsenga".
Kuchokera ku zomera, zikasakanizidwa ndi mankhwala, zimatha kupangitsa kuti mankhwalawa akhale ochuluka kwambiri, awonetsetse kuti amawoneka bwino, komanso amachititsa kuti zotsatira zake zikhale zolimba.
Zimakhala zoonekera komanso zomata zikakhala zonyowa, zomwe zimapangitsa kuti zikhale zofala m'mafakitale ambiri, makamaka chifukwa ndizofewa m'matupi athu ndipo zimatengedwa kuti ndi zokonda zachilengedwe.
Kodi hydroxypropyl methylcellulose amapangidwa bwanji?
Kuti mukhale osavuta komanso omveka bwino, ndikuwonetsa mwachidule gawo lililonse mwamagawo awa:
- Zopangira: Zopangira zazikulu za hydroxypropyl methylcellulose ndi cellulose ya chomera, yomwe nthawi zambiri imachokera ku zamkati zamatabwa kapena thonje.
- Chithandizo cha alkali: Thirani cellulose ndi mankhwala amphamvu amchere (monga sodium hydroxide) kuti musinthe kukhala cellulose yamchere.
- Methylation: Mu sitepe iyi, cellulose ya alkaline imathandizidwa ndi methyl chloride kuyambitsa magulu a methyl pama cellulose.
- Hydroxypropylation: Apa ndi pamene hydroxypropyl imayambitsidwa. Methylcellulose imakhudzidwa ndi epoxy propane, zomwe zimapangitsa kuti magulu a hydroxypropyl agwirizane.
- Kuyeretsa: Kenako yeretsani hydroxypropyl methylcellulose yomwe mwapeza kuti muchotse mankhwala aliwonse osakhudzidwa ndi zonyansa zina. Izi nthawi zambiri zimaphatikizapo kuchapa, kusefa, ndi kuyanika.
- Kupera ndi granulation: Pomaliza, zouma hydroxypropyl methylcellulose ndi pansi ufa wabwino ndipo akhoza granulated kupeza chofunika tinthu kukula kwa cholinga chake ntchito.
Mlingo wa methylation ndi hydroxypropylation ukhoza kuwongoleredwa panthawi yopanga, zomwe zingakhudze kusungunuka ndi kukhuthala kwa hydroxypropylmethylcellulose.
Makinawa amalola opanga kusintha mawonekedwe awo kuti agwiritse ntchito kuti akwaniritse zosowa zazinthu zosiyanasiyana.
Kodi hydroxypropyl methylcellulose ingakhale ndi ntchito zingapo?
Inde, ndi chinthu chosinthika kwambiri chomwe chimagwira ntchito m'mafakitale angapo, ndipo pali zitsanzo zingapo. Ndipotu mmodzi wa iwo anatchulidwa kumayambiriro kwa nkhaniyo.
Tiyeni tikambirane ndi makampani.
- M'makampani opanga mankhwala.
Mapiritsi omasulidwa osasunthika: Hydroxypropylmethylcellulose amagwiritsidwa ntchito m'mapangidwe a mapiritsi kuti azitha kutulutsa kuchuluka kwa zosakaniza zomwe zimagwira ntchito ndikuwonetsetsa kutulutsidwa kwa mankhwala kwanthawi yayitali.
Madontho a m'maso: Amagwiritsidwa ntchito ngati misozi yochita kupanga pokonzekera maso kuti achepetse zizindikiro za maso owuma.
Chophimba: Mapangidwe ake opangira filimu amawathandiza kuti azigwiritsidwa ntchito ngati chophikira pamapiritsi ndi makapisozi, kukonza bata ndi maonekedwe.
- M'makampani azakudya.
Thickener ndi stabilizer: Hydroxypropylmethylcellulose amawonjezeredwa ku zakudya zosiyanasiyana, monga sauces, maswiti, ndi zinthu zophikidwa, kuti akwaniritse kugwirizana kapena kapangidwe kake.
Cholowa chamasamba: Ndiwotchuka m'malo mwa gelatin muzakudya zamasamba kapena zakudya zamasamba, chifukwa imapereka kusasinthika kofanana ndi gel, ndipo ilibe zosakaniza zochokera ku nyama.
Zomatira matailosi a Ceramic ndi pulasitala: Hydroxypropylmethylcellulose imagwiritsidwa ntchito ngati chosungira madzi kuti iwonetsetse kuti kuyanika kosasintha ndikuwongolera magwiridwe antchito.
- Mu zodzoladzola.
Thickener mu mafuta odzola ndi zonona za nkhope: Zimapereka mawonekedwe osalala komanso osasinthasintha kwa zodzoladzola.
Ilinso ndi mapulogalamu ena enieni.
- Kupanga inki: kumagwiritsidwa ntchito ngati thickener ndi stabilizer.
- Ulimi: Amagwiritsidwa ntchito ngati chomangira njere za granular.
- Makampani opanga nsalu: amagwiritsidwa ntchito popanga nsalu kuti awonjezere ulusi panthawi yoluka.
Mafunso ena wamba
- Kodi hydroxypropyl methylcellulose ingagwiritsidwe ntchito moyenera?
Inde, hydroxypropyl methylcellulose nthawi zambiri imawonedwa ngati yotetezeka kuti igwiritsidwe ntchito ndipo yavomerezedwa kuti igwiritsidwe ntchito pazakudya ndi mabungwe ambiri olamulira padziko lonse lapansi.
- Kodi hydroxypropyl methylcellulose imatha kuwonongeka?
Inde, monga chochokera ku cellulose, hydroxypropylmethylcellulose ndi biodegradable, zomwe zimapangitsa kuti ikhale yogwirizana ndi chilengedwe poyerekeza ndi ma polima ena opangidwa.
- Chifukwa chiyani mumagwiritsa ntchito hydroxypropyl methylcellulose m'madontho a maso?
Hydroxypropylmethylcellulose imatha kutsanzira misozi yachilengedwe, kupereka mafuta ndi mpumulo kwa maso owuma komanso owopsa. Mawonekedwe ake a viscous amathandiza kuti azikhala pamwamba pa maso nthawi yaitali kuposa madzi, kupereka chithandizo chokhalitsa.
