IHydroxypropyl Methylcellulose (HPMC)yi-nonionic cellulose ether efunyenwe ngokuguqulwa kweekhemikhali kwe-cellulose yezityalo zendalo. Isetyenziswa kakhulu ekutyeni, kumayeza, kwizinto zokuthambisa, kwizixhobo zokwakha nakwezinye iindawo.
1. Umthombo kunye neempawu zesakhiwo se-HPMC
I-HPMC yi-polymer compound enyibilikayo emanzini eyenziwe yi-methylation kunye ne-hydroxypropylation reaction esekelwe kumqhaphu wendalo, i-pulp yomthi kunye nezinye iifayibha zezityalo. Ayinazo izithako zezilwanyana kwaye ayibandakanyi ukuguqulwa kwezakhi zofuzo. Ke ngoko, isetyenziswa njengesongezelelo ekutyeni kwaye ifanelekile kwiindlela ezahlukeneyo zokutya ezifana nokutya kwemifuno, i-halal, kunye nokutya kwamaJuda.
Imisebenzi ephambili ye-HPMC kukuqina, ukwakheka kwefilimu, ukuhlanganiswa okuzinzileyo, ukukhululwa okulawulwayo, njl. Ngenxa yokuzinza kwayo okuhle kobushushu, iikhalori eziphantsi, kunye nokungagayeki kakuhle kokutya kunye nokufunxwa ngumzimba womntu, iye yaba sisongezelelo esisebenzayo esisetyenziswa kakhulu kwishishini lokutya.
2. Isiqinisekiso sokhuseleko lokutya samazwe ngamazwe kunye nemigaqo ziyakuvumela
I-HPMC iye yaqatshelwa njengesongezo esikhuselekileyo nesityiwayo ngabaphathi bokutya namayeza kumazwe amaninzi nakwiindawo ezahlukeneyo, ngolu hlobo lulandelayo:
IKomiti yeeNgcali eziHlangeneyo zeZongezo zokutya (i-JECFA) ye-Food and Agriculture Organisation/World Health Organization (i-FAO/i-WHO) yeZizwe eziManyeneyo
idwelisa i-HPMC njengesithambisi-mafutha, i-emulsifier kunye ne-stabilizer enokusetyenziswa ekutyeni, kwaye akukho mda wokutya imihla ngemihla (i-ADI ayichazwanga), nto leyo ebonisa ukuba ubuthi buphantsi kakhulu.
Ulawulo Lokutya Neziyobisi lwase-US (FDA)
ihlela i-HPMC njenge-GRAS (Ngokubanzi Iyaziwa Njengekhuselekileyo), ivumela ukuba isetyenziswe ekutyeni, kumayeza, kwiimveliso zempilo nakwezinye iindawo.
IManyano yaseYurophu (i-EU)
Phantsi koMthetho wezongezo zokutya waseYurophu uNombolo E464, i-HPMC ivunyiwe ukuba isetyenziswe njengesongezelelo sokutya.
Umgangatho woKhuseleko lokutya weSizwe saseTshayina (GB2760)
Ichaza ngokucacileyo i-HPMC njengesongezo sokutya, esinokusetyenziswa kwiigobolondo zekhaphu, ukutya okunamafutha aphantsi, iimveliso zepasta, iimveliso zobisi, ukutya okukhenkcezisiweyo, njl.njl., kwaye ichaza ububanzi bokusetyenziswa kunye nokusetyenziswa okuphezulu.
3. Izifundo zetyhefu kunye nohlalutyo lokhuseleko lwebhayoloji
Ukhuseleko lwebhayoloji lwe-HPMC luqinisekiswe zizilingo ezininzi zezilwanyana kunye novavanyo lweklinikhi:
Iziphumo zovavanyo lwetyhefu zibonisa ubuthi obuphantsi kakhulu: Izifundo ezinobungozi obubukhali, obungaphantsi kobuqatha kunye nobobuhlala buhleli zibonise ukuba akukho ziphumo zimbi zibonakalayo eziye zabonwa nangona kusetyenziswe idosi enkulu ye-HPMC.
Ayigaywanga kwaye ayifunxwa ngumzimba womntu: I-HPMC ayizukubola kwaye ifunxwe zii-enzymes zesisu, ngoko ke ayithathi nxaxheba kwi-metabolism yamandla kwaye ayizukubangela ukuba iswekile yegazi inyuke. Ifanelekile kubantu abanesifo seswekile okanye abantu abafuna ukunciphisa umzimba.
Akukho bungozi bomhlaza, akukho bungozi bokukhula kwe-teratogenic, akukho bungozi bokusasazeka kwe-genotoxicity: Ukusetyenziswa ixesha elide akubonisi bungqina bokuba kukho ubungozi bomhlaza okanye ukusasazeka kwe-genotoxicity.
4. Imizekelo eqhelekileyo yokusetyenziswa ekutyeni
I-HPMC isetyenziswa kakhulu ekutyeni, kwaye ukusetyenziswa okuqhelekileyo kuquka:
Iikhaphu zemifuno: I-HPMC yeyona nto ikhethwayo yokwenza iikhaphu zezityalo, ezithatha indawo ye-gelatin yendabuko, ezifanelekileyo kubantu abatya imifuno.
Ukutya okungenamafutha amaninzi/ukutya okutshintshiselana nokutya: okusetyenziselwa ukulinganisa incasa yamafutha, ukwandisa ukutyeba kunye nokuhlutha, okufumaneka rhoqo kwi-ayisikhrim engenamafutha amaninzi, iiproteni zebha, ii-milkshakes ezinesondlo, njl.njl.
Iinoodles: Ukongeza i-HPMC kwiinoodles nesonka kunokuphucula ukuthamba, ukulwa nokwaluphala, incasa kunye nokugcinwa komswakama.
Ukutya okuqandisiweyo ngokukhawuleza: Kuphucula uzinzo lokumila kokutya ngexesha lokuqandisa nokunyibilika.
Iimveliso zobisi kunye neziselo: Zisetyenziselwa ukuxuba, ukumiswa kunye nokuzinzisa ii-emulsions, ezifana neziselo zebhaktheriya ye-lactic acid, iziselo zeproteni, njl.njl.
5. Ngaba kukho naziphi na iingxaki zeengozi okanye ze-allergies?
Ngokubanzi, i-HPMC ayinayo i-allergenicity ininzi kakhulu kuba yi-compound ephuma kwizityalo ecocekileyo kakhulu engenaproteni kwaye ayizukubangela i-allergy. Kwiimeko ezingaqhelekanga kakhulu, ukuba umntu unomdla kakhulu kwi-cellulose additives, inokubangela ukungakhululeki okuncinci kwesisu (njengokudumba kunye nokunyuka kwe-flatulence), kodwa oku kunokunciphisa ngokunciphisa idosi okanye ukuyeka ukuyisebenzisa.
6. I-HPMC ikhuselekile kwaye iyatyiwa, kwaye inamathuba amaninzi okusetyenziswa kwayo
I-Hydroxypropyl methylcellulose (HPMC), njengesongezelelo sokutya esisebenzayo esinemvelaphi yendalo kunye nokuqinisekiswa kokhuseleko, iyaziwa ngokubanzi njengekhuselekileyo ukutyiwa kumazwe ngamazwe nasekhaya. Inezibonelelo zokuba ayinabungozi, ayibangeli i-allergies, ayifunxwa, kwaye inemisebenzi eyahlukeneyo, kwaye ibe yinxalenye ebalulekileyo kushishino lokutya.
