Polyvinylpolypyrrolidone (PVPP) yog ib qho tseem ceeb hauv kev tsim cov cawv txiv hmab thiab npias. Nws lub peev xwm los xaiv khi thiab tshem tawm haze-forming polyphenols thiab tannins daws cov teeb meem tseem ceeb ntsig txog kev pom meej, saj, thiab kev ruaj ntseg hauv cov dej haus no. Nyob rau hauv winemaking, PVPP txhim kho qhov meej thiab saj ntawm cov cawv thaum stabilizing nws cov xim, ua rau ib yam khoom uas yog ob qho tib si visually txaus siab thiab txaus siab rau haus. Hauv kev tsim npias, PVPP tiv thaiv cua daj cua dub, kom ntseeg tau tias lub npias tseem ruaj khov thiab ruaj khov thoob plaws hauv nws lub txee lub neej, yog li txhim kho nws txoj kev lag luam thiab cov neeg siv khoom txaus siab.

Raws li kev lag luam dej haus txuas ntxiv txhim kho thiab kev cia siab ntawm cov neeg siv khoom nce siab, lub luag haujlwm ntawm PVPP hauv kev ua kom cov khoom lag luam ntshiab, ruaj khov, thiab cov dej haus zoo yuav tseem ceeb heev. Nws txoj kev ua tau zoo, ntau yam, thiab siv tau yooj yim ua rau nws yog ib qho khoom siv tsis tseem ceeb rau winemakers thiab brewers ib yam nkaus, ua rau muaj kev vam meej thiab kev loj hlob ntawm kev lag luam thoob ntiaj teb dej haus.

1. General khoom thiab solubility

2. Hygroscopicity

PVPP tus nqi nqus dej nce ntxiv nrog nce cov av noo.

3. Me me ntawm cov gel tsim

Kev tsim ntawm gel inhibits kev nkag mus ntawm cov dej rau hauv cov ntsiav tshuaj, ua kom qeeb ntawm cov ntsiav tshuaj disintegration. Tsis zoo li lwm cov disintegrants, PVPP yog insoluble thiab tsis muaj kev nyiam ua gel txhua.

4. Complexation thiab solubility-pab nyhuv

PVPP tuaj yeem tsim cov complexes nrog ntau yam tshuaj thiab lwm yam tshuaj. Cov txheej txheem tsim yog thim rov qab thiab yuav tsis tsim nyob rau hauv alkaline xov xwm. Nws yooj yim dua los tsim cov complexes nrog cov tshuaj tsw qab uas muaj phenyl thiab / lossis carboxyl pawg. Yog li ntawd, nyob rau hauv kev lag luam tshuaj, nws muaj peev xwm txhim kho cov solubility thiab bioavailability ntawm cov tshuaj, txhim kho saj ntawm paracetamol, adsorb thiab tshem tawm polyphenols thiab tannins los ntawm tinctures thiab tshuaj ntsuab, thiab muaj peev xwm tiv thaiv raws plab, gastritis, ulcers, esophageal hiatal cancer, lwm.
