Chitetezo cha hpmc (hydroxypropyl methylcellulose) kwa thupi la munthu

1. Kuyambitsa koyambira kwa HPMC

Hpmc (hydroxypropyl methylcellulose)ndi kupanga polymer contround kuchokera ku cellulose wachilengedwe. Zimapangidwa ndi kusintha mankhwala kwa cellulose ndipo kumagwiritsidwa ntchito kwambiri ngati mankhwala, chakudya, zodzola komanso zomangamanga. Chifukwa HPMC ndi yosungunuka yamadzi, yopanda mphamvu, yopanda pake komanso yosakwiya, yomwe yakhala yofunikira mu zinthu zambiri.

M'makampani opanga mankhwala, hpmc nthawi zambiri amagwiritsidwa ntchito pokonzekera kukonzekera kuchuluka kwa mankhwala osokoneza bongo, zipolopolo za makapisozi, komanso zolimbitsa thupi za mankhwala. Amagwiritsidwanso ntchito kwambiri ngati triclener, emulsifier, hmeerctifice ndi kukhazikika, ndipo imagwiritsidwa ntchito ngati yophika yotsika mu zakudya zapadera. Kuphatikiza apo, HPMC imagwiritsidwanso ntchito ngati thicker ndi kunyowa zopanga muzodzola.

2. Gwero ndi kapangidwe ka HPMC

HPMC ndi ma cellulose ether opezeka ndi mankhwala a cellulose. Seloesulo yokha ndi polysaccharide yochotsedwa pazomera, zomwe zimapanga gawo lofunikira la bere la cell. Mukamagwiritsa ntchito HPMC, magulu osiyanasiyana (monga hydroxypyll ndi methyl) amadziwitsidwa kuti azisintha madzi ake ndikukula. Chifukwa chake, gwero la HPMC ndilo chomera chomera chomera, ndipo njira yake yosinthira imapangitsa kuti ikhale yosungunuka komanso yosiyanasiyana.

3. Kugwiritsa ntchito HPMC ndi kulumikizana ndi thupi la munthu

Gawo Lachipatala:

M'makampani opanga mankhwala, kugwiritsa ntchito HPMC kumawonetsedwa makamaka pokonzekera mankhwala osokoneza bongo. Popeza hpmc imatha kupanga gelyer wosanjikiza ndikuwongolera kumasulidwa kwa mankhwalawa, imagwiritsidwa ntchito pomasulidwa ndi mankhwala omasulidwa komanso omasulidwa. Kuphatikiza apo, HPMC imagwiritsidwanso ntchito ngati kapusole ku mankhwala osokoneza bongo, makamaka mu makapisozi obzala (makapisozi a masamba), pomwe umatha kusintha mtundu wa nyama ya nyama ndikupatsa mwayi wochezeka.

Kuchokera pangozi, hpmc imawerengedwa ngati yotetezeka ngati mankhwala osokoneza bongo ndipo nthawi zambiri amakhala ndi zinthu zabwino. Chifukwa siyopanda kuganiza kwa thupi la munthu, FDA (chakudya cha US ndi mankhwala) avomereza hpmc ngati chakudya chowonjezera komanso zoopsa zomwe zapezeka chifukwa cha zomwe zapezeka.

Makampani Ogulitsa Chakudya:

HPMC imagwiritsidwa ntchito kwambiri makampani ogulitsa zakudya, makamaka ngati thiCerner, sterubir, ellsifier, etc. Amagwiritsidwa ntchito kwambiri pakudya zakudya zokonzeka, zakumwa, zakudya zamkaka, zakudya zathanzi ndi zinthu zina. HPMC imagwiritsidwanso ntchito popanga zinthu zopanda ma calorie kapena zotsika kwambiri chifukwa cha zosungunulira zamadzi, zomwe zimathandiza kukoma ndi kapangidwe.

HPMC mu chakudya zimapezeka ndi kusinthidwa kwa mankhwala a cellulose, ndipo kugwiritsidwa ntchito kwake ndi kugwiritsa ntchito nthawi zambiri kumayendetsedwa mosamalitsa pazomwe zimagwiritsidwa ntchito pazowonjezera zakudya. Malinga ndi kafukufuku wasayansi zaposachedwa komanso kuchuluka kwa zinthu zachitetezo cha mayiko osiyanasiyana, HPMC imatengedwa yotetezeka kwa thupi la munthu ndipo alibe zovuta zomwe zingachitike kapena ziwopsezo zaumoyo.

Makampani opanga zodzikongoletsera:

Mu cosmetics, hpmc nthawi zambiri amagwiritsidwa ntchito ngati thickener, emulsifier komanso modzira ponyowa. Amagwiritsidwa ntchito kwambiri pazogulitsa monga zowotcha, zoyeretsa za nkhope, zowawa, milomo, etc. Kusintha kapangidwe kake. Chifukwa HPMC imakhala yofatsa ndipo sikukwiyitsa khungu, limawerengedwa kuti ndi cholembera choyenera mitundu yonse ya khungu, makamaka khungu lakhungu.

HPMC imagwiritsidwanso ntchito pamafuta ndi zinthu kukonza khungu kuti zithandizire kukulitsa kukhazikika ndi kusanja kwa zosakaniza za mankhwala.

4. Chitetezo cha HPMC kwa thupi la munthu

Kuzindikira Kwambiri:

Malinga ndi kafukufuku waposachedwa, hpmc imatengedwa yotetezeka kwa thupi la munthu. World World Organisation (ndani), chakudya ndi bungwe laulimi (fao), ndi US FDA WONSE The FDA Mndandanda hpmc ngati "nthawi zambiri amadziwika kuti" (gras) komanso amalola kuti igwiritsidwe ntchito ngati chakudya chowonjezera komanso mankhwala osokoneza bongo.

Kafukufuku wazachipatala komanso kuwunika kwa milandu:

Maphunziro ambiri azachipatala asonyeza kutiHpmcSizimapangitsa kuti zinthu zisinthe kapena zotsatira zoyipa munthawi yayitali. Mwachitsanzo, hpmc akamagwiritsidwa ntchito pokonzekera mankhwala opanga mankhwala, odwala samawonetsa kuti sagwirizana kapena kusapeza kwina. Kuphatikiza apo, palibe mavuto azaumoyo chifukwa chogwiritsa ntchito HPMC mu chakudya. HPMC imawonekanso yotetezeka m'magulu ena apadera pokhapokha ngati munthu wawo amayambitsa zinthu zina.

Thupi lawo siligwirizana ndi zovuta zomwe zimachitika:

Ngakhale HPMC sikuti zimayambitsa matupi awo, anthu ochepa omvera kwambiri amatha kukhala ndi zovuta zomwe sizigwirizana ndi izi. Zizindikiro za thupi lawo siligwirizana lingaphatikizepo redness, kuyabwa, komanso kupumira kovuta, koma milandu yotere ndiyosowa kwambiri. Ngati kugwiritsa ntchito zinthu kwa HPMC kumayambitsa kusasangalala kulikonse, siyani kugwiritsa ntchito nthawi yomweyo ndikuwona dokotala.

Zotsatira zakugwiritsa ntchito kwa nthawi yayitali:

Kugwiritsa ntchito kwa nthawi yayitali kwa HPMC sikungapangitse zovuta zilizonse zomwe zimadziwika pa thupi la munthu. Malinga ndi kafukufuku wapano, palibe umboni kuti HPMC idzawonongedwa ngati chiwindi ndi impso, kapena sizikhudza chitetezo chathupi kapena kuchititsa matenda athupi kapena kuchititsa matenda athupi kapena kuchititsa matenda athupi kapena kuchititsa matenda athupi kapena kuchititsa matenda athupi kapena kubweretsa matenda osachiritsika. Chifukwa chake, kugwiritsa ntchito kwa nthawi yayitali kwa HPMC kuli kotetezeka pansi pa zakudya zomwe zilipo komanso zosokoneza bongo.

5. Kumaliza

Monga gawo limodzi lochokera ku zomera zachilengedwe cellulose, HPMC imagwiritsidwa ntchito kwambiri m'minda yambiri monga mankhwala, chakudya ndi zodzoladzola. Ziwerengero zambiri zamaphunziro zasayansi komanso kuwunika kwapo zomwe zawonetsa kuti HPMC ndi yotetezeka mkati mwa kugwiritsa ntchito mitundu yogwiritsidwa ntchito ndipo ilibe zoopsa kapena pathogenic zoopsa za munthu. Kaya kukonzekera kwa mankhwala opangira mankhwala, zowonjezera chakudya kapena zodzoladzola, hpmc zimawerengedwa bwino komanso zothandiza. Zachidziwikire, kuti mugwiritse ntchito chilichonse, malangizo oyenera ogwiritsira ntchito ayenera kutsatiridwa, kugwiritsidwa ntchito kwambiri kuyenera kupewedwa, ndipo chidwi chapamtima chikuyenera kulipidwa kuti munthu awonongeke chifukwa cha ntchito. Ngati muli ndi mavuto apadera azaumoyo kapena nkhawa, tikulimbikitsidwa kukaonana ndi dokotala kapena akatswiri.
