1. Chiyambi cha HPMC
HPMC (Hydroxypropyl Methylcellulose)ndi polima yopangidwa ndi polima yochokera ku cellulose yachilengedwe. Amapangidwa makamaka ndi kusintha kwa mankhwala a cellulose ndipo amagwiritsidwa ntchito kwambiri muzamankhwala, chakudya, zodzoladzola ndi zomangamanga. Chifukwa HPMC ndi madzi sungunuka, si poizoni, zoipa ndi zosakwiyitsa, wakhala pophika kiyi mu mankhwala ambiri.
M'makampani opanga mankhwala, HPMC nthawi zambiri imagwiritsidwa ntchito pokonzekera kumasulidwa kosalekeza kwa mankhwala, zipolopolo za kapisozi, ndi zolimbitsa thupi. Amagwiritsidwanso ntchito kwambiri muzakudya monga thickener, emulsifier, humectant ndi stabilizer, ndipo amagwiritsidwa ntchito ngati chopangira chochepa cha calorie muzakudya zina zapadera. Komanso, HPMC amagwiritsidwanso ntchito monga thickener ndi moisturizing pophika mu zodzoladzola.
2. Gwero ndi kapangidwe ka HPMC
HPMC ndi etha ya cellulose yomwe imapezeka mwa kusintha kwa mankhwala a cellulose yachilengedwe. Cellulose palokha ndi polysaccharide yotengedwa ku zomera, yomwe ndi gawo lofunika kwambiri la makoma a zomera. Mukapanga HPMC, magulu osiyanasiyana ogwira ntchito (monga hydroxypropyl ndi methyl) amayambitsidwa kuti apititse patsogolo kusungunuka kwake kwamadzi komanso kukhuthala kwake. Choncho, gwero la HPMC ndi zomera zachilengedwe zopangira, ndipo ndondomeko yake yosinthidwa imapangitsa kuti ikhale yosungunuka komanso yosunthika.
3. Kugwiritsa ntchito HPMC ndi kukhudzana ndi thupi la munthu
Malo azachipatala:
M'makampani opanga mankhwala, kugwiritsa ntchito HPMC kumawonekera makamaka pokonzekera kumasulidwa kwamankhwala. Popeza HPMC imatha kupanga gel osanjikiza ndikuwongolera bwino kuchuluka kwa mankhwalawa, imagwiritsidwa ntchito kwambiri popanga mankhwala omasulidwa komanso owongolera. Kuphatikiza apo, HPMC imagwiritsidwanso ntchito ngati chipolopolo cha kapisozi chamankhwala, makamaka mu makapisozi amasamba (makapisozi amasamba), pomwe imatha kulowa m'malo mwa gelatin yachikhalidwe ya nyama ndikupatsanso mwayi wokonda zamasamba.
Kuchokera pachitetezo, HPMC imawonedwa kuti ndi yotetezeka ngati chinthu chamankhwala ndipo nthawi zambiri imakhala ndi kuyanjana kwabwino. Chifukwa sichikhala ndi poizoni komanso sichimasokoneza thupi la munthu, a FDA (US Food and Drug Administration) avomereza HPMC ngati chowonjezera cha chakudya komanso chothandizira mankhwala, ndipo palibe zoopsa za thanzi zomwe zimachitika chifukwa chogwiritsa ntchito nthawi yayitali.
Makampani azakudya:
HPMC chimagwiritsidwa ntchito mu makampani chakudya, makamaka monga thickener, stabilizer, emulsifier, etc. Amagwiritsidwa ntchito okonzeka kudya zakudya, zakumwa, maswiti, mkaka, zakudya thanzi ndi mankhwala ena. HPMC amagwiritsidwanso ntchito nthawi zambiri kupanga otsika kalori kapena otsika mafuta mankhwala chifukwa madzi sungunuka katundu, amene bwino kukoma ndi kapangidwe.
HPMC m'zakudya imapezeka mwa kusintha kwa mankhwala a cellulose ya chomera, ndipo ndende yake ndi kagwiritsidwe ntchito kake nthawi zambiri zimayendetsedwa mosamalitsa malinga ndi miyezo yogwiritsira ntchito zowonjezera zakudya. Malinga ndi kafukufuku waposachedwa wasayansi komanso miyezo yachitetezo chazakudya m'maiko osiyanasiyana, HPMC imadziwika kuti ndi yotetezeka m'thupi la munthu ndipo ilibe zovuta kapena zoopsa paumoyo.
Makampani opanga zodzoladzola:
Mu zodzoladzola, HPMC zambiri ntchito monga thickener, emulsifier ndi moisturizing pophika. Amagwiritsidwa ntchito kwambiri pazinthu monga zonona, zoyeretsa nkhope, zopaka m'maso, zopaka milomo, ndi zina zotero kuti zisinthe maonekedwe ndi kukhazikika kwa mankhwalawa. Chifukwa HPMC ndi wofatsa ndipo sichimakwiyitsa khungu, imatengedwa kuti ndi chinthu choyenera kwa mitundu yonse ya khungu, makamaka khungu lofewa.
HPMC amagwiritsidwanso ntchito mafuta odzola ndi mankhwala kukonza khungu kuthandiza kupititsa patsogolo bata ndi malowedwe a mankhwala zosakaniza.
4. Chitetezo cha HPMC ku thupi la munthu
Kuwunika kwa Toxicological:
Malinga ndi kafukufuku wamakono, HPMC imatengedwa kuti ndi yotetezeka kwa thupi la munthu. Bungwe la World Health Organisation (WHO), Food and Agriculture Organisation (FAO), ndi US FDA onse adawunika mozama pakugwiritsa ntchito HPMC ndipo akukhulupirira kuti kugwiritsidwa ntchito kwake muzamankhwala ndi chakudya pazakudya sikungakhudze thanzi la munthu. A FDA amatchula HPMC ngati chinthu "chodziwika kuti ndi chotetezeka" (GRAS) ndipo chimalola kuti chigwiritsidwe ntchito ngati chowonjezera cha chakudya komanso chothandizira mankhwala.
Kafukufuku wachipatala ndi kusanthula zochitika:
Maphunziro ambiri azachipatala asonyeza zimenezoMtengo wa HPMCsichimayambitsa zovuta zilizonse kapena zotsatira zoyipa mkati mwazogwiritsidwa ntchito bwino. Mwachitsanzo, pamene HPMC ntchito mankhwala kukonzekera, odwala kawirikawiri sasonyeza thupi lawo siligwirizana kapena kusapeza. Komanso, palibe mavuto thanzi chifukwa kwambiri ntchito HPMC chakudya. HPMC imawonedwanso kuti ndi yotetezeka m'magulu ena apadera pokhapokha ngati munthu sangagwirizane ndi zosakaniza zake.
Thupi lawo siligwirizana ndi zoyipa:
Ngakhale HPMC nthawi zambiri imayambitsa kusamvana, anthu ochepa kwambiri amatha kukhala ndi ziwengo. Zizindikiro za ziwengo zitha kukhala zofiira pakhungu, kuyabwa, komanso kupuma movutikira, koma zochitika zotere sizichitika kawirikawiri. Ngati ntchito HPMC mankhwala zimayambitsa kusapeza kulikonse, kusiya ntchito yomweyo ndi dokotala.
Zotsatira zakugwiritsa ntchito nthawi yayitali:
Kugwiritsa ntchito nthawi yayitali kwa HPMC sikungabweretse zotsatira zoyipa zomwe zimadziwika pathupi la munthu. Malinga ndi kafukufuku wamakono, palibe umboni wosonyeza kuti HPMC idzawononga ziwalo monga chiwindi ndi impso, komanso sizidzakhudza chitetezo cha mthupi cha munthu kapena kuyambitsa matenda aakulu. Chifukwa chake, kugwiritsa ntchito kwanthawi yayitali kwa HPMC ndikotetezeka pansi pamiyezo yomwe ilipo kale yazakudya ndi mankhwala.
5. Mapeto
Monga pawiri lochokera ku zomera zachilengedwe mapadi, HPMC chimagwiritsidwa ntchito m'madera ambiri monga mankhwala, chakudya ndi zodzoladzola. Chiwerengero chachikulu cha maphunziro asayansi ndi kuwunika kwa toxicological kwawonetsa kuti HPMC ndi yotetezeka mkati mwazoyenera kugwiritsa ntchito ndipo ilibe kawopsedwe kodziwika kapena kuopsa kwa thupi la munthu. Kaya mukukonzekera mankhwala, zowonjezera zakudya kapena zodzoladzola, HPMC imawonedwa ngati yotetezeka komanso yothandiza. Zachidziwikire, pakugwiritsa ntchito mankhwala aliwonse, malamulo ogwiritsidwira ntchito ayenera kutsatiridwabe, kugwiritsa ntchito mopitirira muyeso kuyenera kupewedwa, ndipo tcheru kwambiri chiyenera kuperekedwa ku zomwe zingachitike pakhungu pakagwiritsidwe ntchito. Ngati muli ndi vuto lapadera la thanzi kapena nkhawa, ndi bwino kukaonana ndi dokotala kapena katswiri.
