Iwo macapsules echirimwa anoshandiswa mune edu akagadzirwa zvigadzirwa akagadzirwa nehydroxypropylmethylcellulose (HPMC), inozivikanwawo sehydroxypropylmethylcellulose. Zvino, munguva yakapfuura, zvaigoneka kunyora zvinyorwa izvi pazita:
Zvimwe zvinongedzo:chirimwa capsules (chirimwa fiber nemvura)
Asi ipapo iyo FDA yakashandura mirau yekunyora kuti ide heti dzemuriwo dzinyorwe senge hydroxypropyl methylcellulose kana hydroxypropyl methylcellulose.
Naizvozvo, zvinofanirwa kucherechedzwa kutanga kuti hydroxypropyl methylcellulose phthalate (HPMCP) chinhu chakasiyana kubva kunanga HPMC (hydroxypropyl methylcellulose kana hydroxypropyl methylcellulose). Hungu, shoko iri rinounza kusiyana kukuru.
Zvinoenderana netafura yekutsanangurwa yemugadziri weheti yemuriwo:
HPMC chigadzirwa chirimwa chiri chimiro chakacheneswa cheselulosi yakabviswa kubva muhuni pulp. Sekureva kweAnnex I yeEU Regulation No. 1169/2011 pakupa ruzivo rwechikafu kune vatengi, HPMC inorondedzerwa se "fiber" uye inotsanangurwa sepolymer yemakomisheni emvura kabhoni ane matatu kana anopfuura mamonomer unit, ayo asingagayiwe kana kunyura mu ura hudiki hwemunhu.
Nekudaro, nzira dzazvino dzekuyedza marabhoritari yekudya fiber, senge AOAC 985.29, hainyatso kuona HPMC sefayibha yekudya. Zvisinei, HPMC inodyiwa kabhohaidhireti polymer, fiber yezvokudya ine migumisiro inobatsira yehutano, iyo yakave yakagamuchirwa neuchapupu hwezvesayenzi, uye naizvozvo inogona kuziviswa nokuzvidira.
Kune avo vasina kudzidza chemistry yakawandisa
Cellulose iketani inoumbwa nekabhoni, haidrojeni, uye okisijeni, kazhinji inoumbwa nemazana kusvika kuzviuru zvekabhoni, haidrojeni, uye okisijeni maketani pamwechete.
Hydroxyl - zvinoreva kuti kune okisijeni nehaidhirojeni zvakabatana pane imwe nzvimbo pacheni ye cellulose, kwete kungoita haidrojeni.
Propyl - zvinoreva kuti kune cheni yepadivi pane imwe nzvimbo pacheni, apo maatomu matatu ecarbon akakomberedzwa nehydrogen.
Methyl - Zvakafanana nepropyl, asi kwete matatu makabhoni, asi imwe chete.
Isa zvinhu izvi zvina pamwechete uye iwe uchawana = hydroxypropyl methylcellulose
Kuti unyatsoongorora ruzivo urwu uye uone kuti hapana zvinyorwa zvakaregererwa kana kuti zvakashongedzwa, ndakatarisa kana Dr. Joseph Mercola (chiremba wechokwadi ane ruzivo rwakakwana rwevatsvakurudzi venguva yakazara) akanyora zvinyorwa pamusoro pe hydroxypropyl methylcellulose. Aiwa ndakabva ndatarisa masupplements ake kuti macapsules ake akagadzirwa nei. Ehe, iwo akanyorwa pasi pe 'Zvimwe Zvinosanganiswa: Hydroxypropylmethylcellulose'.
Saka ini ndinofunga isu tinogona kutaura chokwadi kuti iyo yakakosha ndeyekuti hydroxypropyl methylcellulose ichirimwa-based dietary fiber.
Chimwe chikamu chinowanzo onekwa mune zvatinowedzera ndeye hydroxypropyl methylcellulose, iyo inowanzo shandiswa kugadzira capsules.
Hydroxypropylmethylcellulose inowanzo torwa kubva kune chirimwa cellulose, inova kabhohaidhiretsi inowanikwa muchirimwa sero madziro. Mushonga chaiwo uyu unowanzoshandiswa mukugadzira macapsules emuriwo.
Hydroxypropylmethylcellulose inowanzoonekwa mumhando ye hydroxypropylmethylcellulose kana HPMC mune zvinyorwa zvinyorwa, zvakafanana ne "magical powder".
Kubva pamiti, kana yakasanganiswa muchigadzirwa, inogona kuita kuti chigadzirwa chiwedzere, ive nechokwadi chekugadzirwa kwakatsetseka, uye kunyange kuita kuti mhedzisiro yacho igare yakasimba.
Iri pachena uye inonamira kana yakanyorova, zvichiita kuti ive chinhu chakajairika mumaindasitiri mazhinji, kunyanya nekuti yakapfava kumiviri yedu uye inoonekwa seyakagadzikana.
Ko hydroxypropyl methylcellulose inogadzirwa sei?
Kuti tichengetedze zviri nyore uye zvakajeka, ndichasuma muchidimbu chimwe nechimwe chezvikamu zvinotevera:
- Raw material extraction: Iyo huru mbishi yehydroxypropyl methylcellulose chirimwa cellulose, kazhinji inotorwa kubva muhuni pulp kana donje lint.
- Alkali treatment: Bata cellulose nealkaline solution (yakadai sesodium hydroxide) kuishandura kuita alkaline cellulose.
- Methylation: Munhanho iyi, alkaline cellulose inobatwa nemethyl chloride kuunza methyl mapoka pane cellulose mamorekuru.
- Hydroxypropylation: Apa ndipo panounzwa hydroxypropyl. Methylcellulose inopindirana ne epoxy propane, zvichikonzera kubatana kwemapoka ehydroxypropyl.
- Kucheneswa: Wobva wachenesa iyo yakawanikwa hydroxypropyl methylcellulose kubvisa chero makemikari asina kubatwa uye kumwe kusvibiswa. Izvi zvinowanzobatanidza kuwacha, kusefa, uye kuomesa.
- Kukuya negranulation: Chekupedzisira, iyo yakaomeswa hydroxypropyl methylcellulose inogayiwa kuita hupfu hwakatsetseka uye inogona kugezwa kuti iwane saizi inodiwa yekushandiswa kwayo.
Iyo dhigirii yemethylation uye hydroxypropylation inogona kudzorwa panguva yekugadzira, izvo zvinokanganisa kunyungudika uye viscosity maitiro eiyo inowanikwa hydroxypropylmethylcellulose.
Iyi meshini inobvumira vagadziri kugadzirisa hunhu hwavo kune chaiwo maapplication kusangana nezvinodiwa zvezvakasiyana zvigadzirwa.
Ko hydroxypropyl methylcellulose inogona kuve nekushandisa kwakawanda here?
Ehe, chinhu chakasiyana-siyana chinoita basa mumaindasitiri mazhinji, uye kune akati wandei mienzaniso. Kutaura zvazviri, mumwe wavo ataurwa kwokutanga kwenyaya yacho.
Ngatitaurei nezvazvo nemaindasitiri.
- Muindasitiri yemishonga.
Mapiritsi ekusunungurwa akasimudzirwa: Hydroxypropylmethylcellulose inoshandiswa mukugadzirwa kwepiritsi kudzora kuburitswa kweanoshanda mishonga yemishonga uye kuve nechokwadi chekuburitswa kwezvinodhaka kwenguva refu.
Madonhwe eziso: Inoshandiswa semisodzi yekugadzira mukugadzirira kwemaziso kudzikisa zviratidzo zvemaziso akaoma.
Coating agent: Iyo firimu-inogadzira zvimiro inoita kuti ishandiswe sechinhu chinoputira mahwendefa nemakapisi, inovandudza kugadzikana uye kutaridzika.
- Muindasitiri yezvekudya.
Thickener uye stabilizer: Hydroxypropylmethylcellulose inowedzerwa kune zvakasiyana siyana zvekudya, senge sosi, dhizeti, uye zvakabikwa zvinhu, kuti uwane inodiwa kuenderana kana magadzirirwo.
Vegetarian substitute: Inotsiva yakakurumbira yegelatin muchikafu chezvinomera kana chikafu chezvinomera, nekuti inopa kuwirirana kwakafanana nejelisi, uye haina zvigadzirwa zvemhuka.
Ceramic tile adhesive uye plaster: Hydroxypropylmethylcellulose inoshandiswa sechinhu chinochengetedza mvura kuti ive nechokwadi chekuomesa uye kuvandudza mashandiro.
- Muzvizoro.
Thickener mune lotion uye kumeso cream: Inopa yakatsetseka magadzirirwo uye kuenderana kwezvizoro.
Iinewo mamwe maapplication chaiwo.
- Kugadzirwa kweinki: inoshandiswa seyakakora uye inodzikamisa.
- Zvekurima: Inoshandiswa sebhainda rembeu dzegranular.
- Indasitiri yemachira: inoshandiswa kugadzira machira kuwedzera shinda panguva yekuruka.
Mimwe mibvunzo yakajairika
- Ko hydroxypropyl methylcellulose inogona kudyiwa zvakachengeteka here?
Ehe, hydroxypropyl methylcellulose inowanzoonekwa yakachengeteka kudyiwa uye yakabvumidzwa kushandiswa muchikafu nemazhinji masangano anodzora pasi rese.
- Ko hydroxypropyl methylcellulose inogona kuparara here?
Ehe, seyakatorwa selulosi, hydroxypropylmethylcellulose inoodza, izvo zvinoita kuti ive nehushamwari kwezvakatipoteredza kana ichienzaniswa nemamwe mapolymer ekugadzira.
- Sei uchishandisa hydroxypropyl methylcellulose mumadonhwe eziso?
Hydroxypropylmethylcellulose inogona kutevedzera hunhu hwemisodzi yechisikigo, ichipa lubrication uye zororo kune yakaoma uye astringent maziso. Iyo viscous properties inobatsira kuti irambe iri pamusoro pemeso kwenguva yakareba kupfuura mvura, ichipa rubatsiro runogara kwenguva refu.
