Amaphilisi ezitshalo asetshenziswa emikhiqizweni yethu eyenziwe nge-hydroxypropylmethylcellulose (HPMC), eyaziwa nangokuthi i-hydroxypropylmethylcellulose. Manje, esikhathini esidlule, bekungenzeka ukuba kufakwe ohlwini lokhu okuqukethwe kulebula:
Ezinye izithako:ama-capsules wezitshalo (i-plant fiber namanzi)
Kepha i-FDA yabe isishintsha imithetho yokulebula ukuze ifune ukuthi izigqoko zemifino zifakwe ohlwini njenge-hydroxypropyl methylcellulose noma i-hydroxypropyl methylcellulose.
Ngakho-ke, kufanele kuqashelwe kuqala ukuthi i-hydroxypropyl methylcellulose phthalate (HPMCP) iyinto ehlukile ku-HPMC eqondile (i-hydroxypropyl methylcellulose noma i-hydroxypropyl methylcellulose). Yebo, leli gama liletha umehluko omkhulu.
Ngokwethebula elicacisiwe lomkhiqizi wezigqoko zemifino:
I-HPMC iwumkhiqizo wesitshalo owuhlobo oluhlanziwe lwe-cellulose olukhishwe ku-pulp yokhuni. Ngokusho kwe-Annex I ye-EU Regulation No. 1169/2011 ekunikezeni ulwazi lokudla kubathengi, i-HPMC ichazwa ngokuthi "ifayibha" futhi ichazwa njenge-polymer yezinhlanganisela zamanzi ekhabhoni enamayunithi amathathu noma ngaphezulu e-monomer, engagayeki noma imuncwe amathumbu amancane omuntu.
Kodwa-ke, izindlela zamanje zokuhlola ilabhorethri yefayibha yokudla, njenge-AOAC 985.29, ayiboni ngokunembile i-HPMC njengefayibha yokudla. Kodwa-ke, i-HPMC iyi-polymer ye-carbohydrate edliwayo, i-fiber yokudla enemiphumela ezuzisayo yomzimba, eye yamukelwa kabanzi ngobufakazi besayensi, ngakho-ke ingamenyezelwa ngokuzithandela.
Kulabo abangazange bafunde chemistry kakhulu
I-Cellulose iketango elakhiwe ikhabhoni, i-hydrogen, nomoya-mpilo, ngokuvamile ahlanganisa amakhulu kuya ezinkulungwaneni zamaketanga ekhabhoni, i-hydrogen, nomoya-mpilo ndawonye.
IHydroxyl - isho ukuthi kunomoya-mpilo kanye ne-hydrogen exhunywe ndawana thize ochungechungeni lwe-cellulose, kunokuba nje i-hydrogen.
I-Propyl - isho ukuthi kukhona iketango eliseceleni endaweni ethile kuketango, lapho ama-athomu ekhabhoni amathathu ezungezwe i-hydrogen.
I-Methyl - Ifana ne-propyl, kodwa hhayi amakhabhoni amathathu, kodwa eyodwa kuphela.
Hlanganisa lezi zinto ezine futhi uzothola=i-hydroxypropyl methylcellulose
Ukuze ngihlole ngokucophelela lolu lwazi futhi ngiqinisekise ukuthi akukho okuqukethwe okuzitshiwe noma okuhlotshisiwe, ngihlole ukuthi uDkt Joseph Mercola (udokotela weqiniso onesethi egcwele yabacwaningi besikhathi esigcwele) ubhale izindatshana nge-hydroxypropyl methylcellulose. Cha ngibe sengibheka ama-supplements akhe ukuthi ama-capsules akhe enziwe ngani. Yebo, afakwe kuhlu ngaphansi kokuthi 'Ezinye Izithako: Hydroxypropylmethylcellulose'.
Ngakho-ke ngicabanga ukuthi singasho nakanjani ukuthi okubalulekile ukuthi i-hydroxypropyl methylcellulose iyi-fiber yokudla esekelwe ezitshalweni.
Ingxenye evame ukuvela ezithanjeni zethu i-hydroxypropyl methylcellulose, evame ukusetshenziselwa ukwenza amaphilisi.
IHydroxypropylmethylcellulose imvamisa itholakala ku-cellulose yezitshalo, okuyi-carbohydrate etholakala ezindongeni zamaseli ezitshalo. Le nhlanganisela ethile isetshenziswa kakhulu ekwenzeni amaphilisi emifino.
I-Hydroxypropylmethylcellulose ngokuvamile ivela ngendlela ye-hydroxypropylmethylcellulose noma i-HPMC ohlwini lwesithako, efana "nempusha yomlingo".
Isuka ezitshalweni, uma ixubene nomkhiqizo, ingenza umkhiqizo ube mkhulu, iqinisekise ukuthungwa okubushelelezi, futhi yenze nomphumela wayo uhlale isikhathi eside.
Isobala futhi iyanamathela uma imanzi, okwenza ibe yinto evamile ezimbonini eziningi, ikakhulukazi ngoba ithambile emizimbeni yethu futhi ithathwa njengenobungani nemvelo.
Ikhiqizwa kanjani i-hydroxypropyl methylcellulose?
Ukugcina ubulula nokucaca, ngizokwethula kafushane isigaba ngasinye kwezilandelayo:
- Ukukhishwa kwempahla eluhlaza: Impahla eyinhloko ye-hydroxypropyl methylcellulose isitshalo se-cellulose, ngokuvamile etholakala ku-pulp yokhuni noma ku-cotton lint.
- Ukwelashwa nge-alkali: Phatha i-cellulose ngesisombululo esiqinile se-alkaline (njenge-sodium hydroxide) ukuze uyiguqule ibe yi-alkaline cellulose.
- I-Methylation: Kulesi sinyathelo, i-alkaline cellulose iphathwa nge-methyl chloride ukwethula amaqembu e-methyl kuma-molecule e-cellulose.
- IHydroxypropylation: Yilapho i-hydroxypropyl yethulwa khona. I-Methylcellulose isabela ne-epoxy propane, okuholela ekuxhumekeni kwamaqembu e-hydroxypropyl.
- Ukuhlanzwa: Bese uhlanza i-hydroxypropyl methylcellulose etholiwe ukuze ususe noma imaphi amakhemikhali angaphenduliwe nokunye ukungcola. Lokhu ngokuvamile kuhlanganisa ukuwasha, ukusefa, nokomisa.
- Ukugaya kanye ne-granulation: Ekugcineni, i-hydroxypropyl methylcellulose eyomisiwe igaywa ibe yimpuphu ecolekile futhi ingenziwa i-granulated ukuze ithole usayizi wezinhlayiyana odingekayo wokusetshenziswa okuhlosiwe.
Izinga le-methylation kanye ne-hydroxypropylation lingalawulwa ngesikhathi senqubo yokukhiqiza, okuzothinta izici ze-solubility kanye ne-viscosity ye-hydroxypropylmethylcellulose etholiwe.
Le nqubo ivumela abakhiqizi ukuthi benze ngokwezifiso izimfanelo zabo zezinhlelo zokusebenza ezithile ukuze bahlangabezane nezidingo zemikhiqizo ehlukahlukene.
Ingabe i-hydroxypropyl methylcellulose ingaba nokusetshenziswa okuningi?
Yebo, kuyisithako esisebenza ngezindlela eziningi esidlala indima ezimbonini eziningi, futhi kunezibonelo ezimbalwa. Eqinisweni, omunye wabo kukhulunywe ngaye ekuqaleni kwesihloko.
Ake sikhulume ngakho ngemboni.
- Embonini yezemithi.
Amaphilisi okukhululwa okuqhubekayo: I-Hydroxypropylmethylcellulose isetshenziswa ekwakhiweni kwethebhulethi ukulawula izinga lokukhululwa kwezithako ezisebenzayo zemithi kanye nokuqinisekisa ukukhululwa kwezidakamizwa isikhathi eside.
Amaconsi esweni: Asetshenziswa njengezinyembezi zokwenziwa ekulungiseleleni amehlo ukuze kudambise izimpawu zamehlo omile.
I-ejenti yokwemboza: Izakhiwo zayo zokwenza ifilimu ziyenza ikwazi ukusetshenziswa njenge-ejenti yokuhlanganisa amaphilisi nama-capsules, ukuthuthukisa ukuzinza nokubukeka.
- Embonini yokudla.
I-Thickener ne-stabilizer: I-Hydroxypropylmethylcellulose yengezwa ekudleni okuhlukahlukene, njengamasoso, ama-dessert, nezimpahla ezibhakwayo, ukuze kuzuzwe ukuvumelana noma ukuthungwa okufunayo.
I-Vegetarian substitute: Kuyinto ethandwayo esikhundleni se-gelatin ekudleni kwemifino noma ukudla kwemifino, ngoba inikeza ukungaguquguquki okufana nejeli, futhi ayiqukethe izithako zemvelaphi yezilwane.
I-Ceramic tile adhesive kanye ne-plaster: I-Hydroxypropylmethylcellulose isetshenziswa njenge-ejenti yokugcina amanzi ukuze kuqinisekiswe ukomiswa okungaguquki futhi kuthuthukise ukucutshungulwa.
- Kwezimonyo.
I-Thickener in lotion kanye nokhilimu wobuso: Inikeza ukuthungwa okubushelelezi nokuvumelana kwezimonyo.
Futhi inezinye izinhlelo zokusebenza ezithile.
- Ukukhiqizwa kwe-inki: isetshenziswa njenge-thickener ne-stabilizer.
- Ezolimo: Isetshenziswa njengesibopho sembewu yegranular.
- Imboni yezindwangu: isetshenziselwa ukulinganisa izindwangu ukuthuthukisa intambo ngesikhathi senqubo yokuluka.
Eminye imibuzo evamile
- Ingabe i-hydroxypropyl methylcellulose ingadliwa ngokuphepha?
Yebo, i-hydroxypropyl methylcellulose ngokuvamile ithathwa njengephephile ukusetshenziswa futhi igunyazwe ukusetshenziswa ekudleni yizikhungo eziningi ezilawulayo emhlabeni jikelele.
- Ingabe i-hydroxypropyl methylcellulose iyabola?
Yebo, njengokuphuma kwe-cellulose, i-hydroxypropylmethylcellulose iyakwazi ukubola, okwenza ivumelane nemvelo uma iqhathaniswa namanye ama-polymers okwenziwa.
- Kungani kufanele usebenzise i-hydroxypropyl methylcellulose kumaconsi wamehlo?
IHydroxypropylmethylcellulose ingakwazi ukulingisa izici zezinyembezi zemvelo, inikeze ukuthambisa kanye nokukhululeka kwamehlo omile napholile. Izici zayo ze-viscous zisiza ukuthi ihlale phezu kwamehlo isikhathi eside kunamanzi, inikeze umphumela wokusiza isikhathi eside.
