Hydroxypropyl methylcellulose kuwonda

Mawu Oyamba

Hydroxypropyl methylcellulose (HPMC) ndi zinthu zapolymeric zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale azakudya, zamankhwala, ndi zodzikongoletsera. Ndi polima yosungunuka m'madzi, yopanda ion, komanso yosawonongeka yochokera ku cellulose. HPMC yakhala ikugwiritsidwa ntchito kwa zaka zambiri ngati thickening wothandizira, emulsifier, stabilizer, ndi gelling wothandizira mu zakudya zosiyanasiyana. M'zaka zaposachedwapa, izo zapezeka kuti angathe ntchito kuwonda.

Njira Yochitira

HPMC ndi hydrophilic polima kuti amatha kuyamwa madzi ndi kutupa kupanga gel osakaniza. Kapangidwe kameneka kamene kamakhala ngati gel kakuganiziridwa kuti ndi kamene kamapangitsa kuchepetsa chilakolako cha chakudya ndikulimbikitsa kukhuta. Amakhulupirira kuti mawonekedwe a gel-ngati a HPMC amapanga chotchinga chakuthupi m'mimba, chomwe chimachepetsa kuyamwa kwa chakudya ndikuwonjezera kukhudzika. Kuphatikiza apo, HPMC imaganiziridwa kuti imachepetsa kuyamwa kwamafuta ndi chakudya, zomwe zingayambitse kuwonda.

Umboni Wachipatala

Pakhala pali maphunziro angapo azachipatala omwe adawunika zotsatira za HPMC pakuchepetsa thupi. Mu kafukufuku wopangidwa mwachisawawa, wakhungu kawiri, woyendetsedwa ndi placebo, maphunziro adapatsidwa HPMC kapena placebo kwa milungu isanu ndi itatu. Pamapeto pa phunziroli, anthu omwe adatenga HPMC adataya kulemera kwambiri kuposa omwe adatenga placebo. Mu kafukufuku wina, maphunziro adapatsidwa HPMC kapena placebo kwa milungu 12. Pamapeto pa phunziroli, anthu omwe adatenga HPMC adataya kulemera kwambiri kuposa omwe adatenga placebo.

Kuphatikiza pa maphunzirowa, pakhala pali maphunziro ena angapo omwe adawunika zotsatira za HPMC pakuchepetsa thupi. Mu kafukufuku wopangidwa mwachisawawa, wakhungu kawiri, woyendetsedwa ndi placebo, maphunziro adapatsidwa HPMC kapena placebo kwa milungu isanu ndi itatu. Pamapeto pa phunziroli, anthu omwe adatenga HPMC adataya kulemera kwambiri kuposa omwe adatenga placebo.

Chitetezo

HPMC nthawi zambiri imawonedwa ngati yotetezeka kuti anthu amwe. Nthawi zambiri imalekerera bwino ndipo imakhala ndi zotsatirapo zochepa. Zotsatira zofala kwambiri zomwe zimanenedwa ndi kukhumudwa pang'ono kwa m'mimba, monga nseru, kusanza, ndi kutsekula m'mimba. Kuphatikiza apo, HPMC imatha kuyanjana ndi mankhwala ena, kotero ndikofunikira kukaonana ndi azaumoyo musanamwe HPMC.

Mapeto

Hydroxypropyl methylcellulose (HPMC) ndi zinthu zapolymeric zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale azakudya, zamankhwala, ndi zodzikongoletsera. Zapezeka kuti zingagwiritsidwe ntchito pochepetsa thupi, chifukwa zimakhulupirira kuti zimapanga chotchinga m'mimba ndi kuchepetsa kuyamwa kwa mafuta ndi chakudya. Maphunziro angapo azachipatala adawunika zotsatira za HPMC pakuchepetsa thupi, ndipo zotsatira zake zakhala zikulonjeza. HPMC nthawi zambiri imawonedwa ngati yotetezeka kuti anthu amwe, ngakhale imatha kuyanjana ndi mankhwala ena.
