Hauv kev tsim khoom noj niaj hnub no, kev tsim cov khoom lag luam tiag tiag tsis yog ib qho yooj yim ua ke ntawm cov khoom siv raw. Nws yog ib tug systematic tsim uas sib npaug functionality, stability, thiab zaum kawg cov neeg siv kev paub. Cov khoom xyaw uas sau rau hauv cov mis- feem ntau me me los yog polymeric nyob rau hauv cov xwm - nquag txiav txim siab seb cov khoom puas tuaj yeem tiv taus lub sijhawm, kub, thiab kev ua lag luam.
Tawm tsam qhov keeb kwm yav dhau los no, polyvinylpyrrolidone (PVP, E 1208) thiab nws daim ntawv sib txuas, PVPP, tau maj mam txav los ntawm tom qab-- scenes excipients mus rau cov khoom tseem ceeb ntawm cov khoom noj khoom haus qib siab.
Cov yam ntxwv ntawm tus yam ntxwv thiab kev ua haujlwm ntawm PVP
Polyvinylpyrrolidone yog dej-soluble polymer nrog lub pob txha ruaj khov thiab cov pab pawg sab nraud, ua kom muaj zog hydrogen bonding thiab complexion nrog ntau yam polar tshuaj.
Hauv daim ntawv thov zaub mov, ob hom tseem ceeb dominate:
Nruab nrab - mus rau siab -molecular- hnyav PVP (K30, K60)
Feem ntau yog siv rau kev tsim cov yeeb yaj kiab, kev khi, txheej, kev tawg sai sai, thiab kev ua kom ruaj khov.
Crosslinked PVPP
Insoluble nyob rau hauv dej, nrog ib tug ntxeem tau network qauv uas xaiv adsorbs polyphenols, proteins, thiab tannins.
Qhov kev sib xyaw no ntawmtswj tau qhov hnyav molecular thiab qhia meej meej ua haujlwmua rau PVP yog ib qho kev ua tau zoo thiab muaj tseeb hauv cov khoom noj khoom haus.
Kev nthuav qhia thiab ruaj khov hauv Npis, Wine, Kua txiv, thiab Vinegar
Hauv cov khoom noj ua kua, feem ntau tsim thiab sawv cev daim ntawv thov ntawm PVP yog nyob rau hauv npias, cawv, kua txiv hmab txiv ntoo, thiab kua txiv hmab txiv ntoo, qhov chaw uas nws ua haujlwm raws li ib tugqhia meej thiab ruaj khov pab pom.
Functional Mechanism
Hauv cov dej haus no, instability feem ntau yog tshwm sim los ntawm:
Polyphenolic compounds
Proteins thiab tannins
Colloids thiab nplua suspended hais
PVPP tsim insoluble complexes nrog polyphenols thiab cov proteins, uas tuaj yeem raug tshem tawm los ntawm kev pom los yog sedimentation. Cov txheej txheem no:
Tiv thaiv kom txias haze tsim
Extens lub neej txee
Txhim kho qhov pom kev pom tseeb
Enhances tsw stability
Hom kev ua noj ntau npaum
Kev lag luam kev coj ua tau sib koom ua ke ntawm cov qauv siv tau zoo:
Recirculating filtration systems:
0.05–0.3 g / L PVPP rov qab siv rau hauv lub txaj lim
Tib - siv koob tshuaj:
5-20 g / hL PVPP ntxiv ncaj qha thiab tshem tawm los ntawm kev pom
Cov txheej txheem no tau siv dav hauv cov khoom siv tes ua IPAs, cov cawv dawb qhuav, sulfite-cov kua txiv hmab txiv ntoo dawb, thiab cov txiv hmab txiv ntoo zoo tshaj.
Los ntawm "Sulfite-Dawb" mus rau Kev Ua Haujlwm Zoo: Lub luag haujlwm tsis tuaj yeem hloov pauv ntawm PVPP
Hauv sulfite- cov kua txiv hmab txiv ntoo dawb thiab siab -kawg vinegars, cov tswv yim tshuaj tua kab mob antioxidant thiab cov lus qhia meej yog nruj nruj. Cov neeg tsim khoom yog li ntawd vam khom ntau rau ntawm lub cev adsorption technologies.
Piv nrog rau cov tshuaj qhia meej ib txwm muaj xws li gelatin lossis bentonite, PVPP muaj qhov zoo meej:
Tsawg heev cuam tshuam rau aroma thiab khoom noj khoom haus Cheebtsam
Ntau dua adsorption selectivity
Cov txheej txheem ntau dua qhov sib xws thiab batch-rau-batch stability
Raws li qhov tshwm sim, PVPP tau dhau los ua tus qauv kev xaiv hauv cov khoom lag luam uas hais txog "natural character," siab clarity, thiab ntev -lub sij hawm ruaj khov.
PVP hauv Cov Khoom Noj Khoom Haus: Yuav luag Indispensable
Thaum cov khoom tsim tawm hloov ntawm cov kua mus rau cov khoom khib nyiab- xws li cov tshuaj ntsiav, ntsiav tshuaj, lossis cov hmoov tam sim ntawd - lub luag haujlwm ntawm PVP tau tshaj tawm.
Hauv cov kab ke no, PVP feem ntau ua haujlwm xws li:
Ib tug binderkom cov ntsiav tshuaj muaj zog thiab uniformity
Ib tug ceev - kev sib cais cov cab kujlos txhim kho solubility thiab dispersion
Ib txheej txheejlos txhim kho qhov tsos, qhov ncauj, thiab tso tus cwj pwm
Ib qho tshuaj tiv thaiv- nplaum thiab noo noo- tswj tus neeg sawv cevlos txhim kho kev ruaj ntseg
Nyob rau hauv kev xyaum, thaum twg ib tug formulation hu rau "hloov sai," "coating," "anti-caking," los yog "moisture retention," PVP feem ntau yog thawj qhov kev xaiv. Rau cov khoom siv tshuaj ntsiav thiab ntsiav tshuaj, kev siv PVP-raws li excipients yog ze rau kev pom zoo thoob ntiaj teb kev lag luam.
Kev txheeb xyuas qhov muaj PVP Los ntawm Cov Ntawv Sau thiab Cov Ntawv Thov
Los ntawm kev txheeb xyuas kev lag luam, qhov muaj PVP lossis PVPP feem ntau tuaj yeem raug xam los ntawm ntau qhov ntsuas:
Cov khoom lag luam yog los ntawm kev qhia meej- qeb dej qab zib lossis daim ntawv noj tshuaj ntau
Cov ntawv thov ua haujlwm suav nrog cov ntsiab lus xws li "paj meej," "ruaj khov," "soluble sai," lossis "anti-caking"
Cov khoom no qhia txog lub neej ntev txee los yog tiv thaiv kom txias haze
Cov teeb liab no feem ntau taw qhia rau ib qho kev txiav txim siab: PVP lossis PVPP yog qhov tseem ceeb ntawm cov qauv tsim.
Factory Recommendation: Manufacturing Stability Behind Functional Performance
Rau kev ua haujlwm polymers xws li PVP, kev ua tau zoo yog txiav txim siab tsis yog los ntawm nominal molecular hnyav tab sis kuj los ntawm kev tsim khoom sib xws thiab kev tswj kom zoo.
Huzhou Sunflower Pharmaceutical Co., Ltd.tau tsim nws cov kev txawj ntse nyob ib ncig ntawm qhov kev lag luam kev muaj tiag, tsom mus rau qhov loj - teev ntau lawm thiab kev tswj xyuas zoo ntawm PVP thiab cov khoom muaj feem xyuam.
Los ntawm kev ua tib zoo xaiv cov khoom siv raw, tswj cov polymerization, cov khoom hnyav molecular faib, thiab kev tswj tsis huv, lub tuam txhab xa PVP thiab PVPP cov khoom uas ua tau raws li qhov xav tau ntawm cov khoom noj thiab cov ntawv thov kev tsim. Qhov tseem ceeb ntawm batch sib xws thiab traceability muab kev ntseeg siab ntev - lub sij hawm txhawb rau cov qauv tsim khoom ruaj khov.
Xaus
Los ntawm kev qhia meej thiab ruaj khov ntawm npias, cawv, kua txiv hmab txiv ntoo, thiab kua txiv hmab txiv ntoo rau kev tsim thiab tawg sai sai ntawm cov tshuaj ntsiav thiab ntsiav tshuaj, polyvinylpyrrolidone (PVP / PVPP) tau hloov zuj zus los ntawm kev xaiv cov khoom ntxiv rau hauv cov khoom lag luam uas paub tab thiab tseem ceeb hauv kev tsim khoom noj niaj hnub.
Qhia meej nrog PVP rau hauv cov qauv-thiab xaiv qhov hnyav molecular thiab daim ntawv tsim nyog- qhia txog qib siab ntawm kev tswj hwm kev ruaj ntseg, txheej txheem kev ntseeg tau, thiab cov khoom zoo. Nyob rau hauv no tsis tu ncua sib, kev manufacturers xws liHuzhou Sunflower Pharmaceutical Co., Ltdtxuas ntxiv muab cov khoom siv hauv paus uas txhawb kev ua kom zoo dua qub thiab premiumization ntawm kev lag luam khoom noj niaj hnub no.
