Mechanism ntawm Carboxymethyl Cellulose (CMC) hauv Wine

Carboxymethyl cellulose (CMC) yog cov dej-soluble polymer muab tau los ntawm cellulose uas feem ntau siv hauv kev lag luam zaub mov ua cov thickener, stabilizer, thiab emulsifier. Hauv kev lag luam cawv, CMC yog siv los txhim kho qhov zoo thiab ruaj khov ntawm cawv. CMC feem ntau yog siv los ua kom khov cawv, tiv thaiv sedimentation thiab haze tsim, thiab txhim kho lub qhov ncauj thiab kev ntxhib los mos ntawm cov cawv. Hauv tsab xov xwm no, peb yuav tham txog cov txheej txheem ntawm CMC hauv cawv.

Stabilization ntawm Wine

Lub luag haujlwm tseem ceeb ntawm CMC hauv cawv yog txhawm rau txhim kho cov cawv thiab tiv thaiv kev ua qias tuaj thiab ua rau haze. Wine yog ib qho kev sib xyaw ntawm cov organic tebchaw, suav nrog cov tshuaj phenolic, cov proteins, polysaccharides, thiab cov zaub mov. Cov tebchaw no tuaj yeem cuam tshuam nrog ib leeg thiab tsim cov aggregates, ua rau sedimentation thiab haze tsim. CMC tuaj yeem ruaj khov cawv los ntawm kev tsim cov txheej txheem tiv thaiv ib puag ncig cov khoom sib txuas no, tiv thaiv lawv los ntawm kev sib cuam tshuam thiab sib sau ua ke. Qhov no tau ua tiav los ntawm kev sib cuam tshuam ntawm cov pawg carboxyl tsis zoo ntawm CMC thiab cov txiaj ntsig zoo ions hauv cawv.

Kev tiv thaiv ntawm Sedimentation

CMC tseem tuaj yeem tiv thaiv sedimentation hauv cawv los ntawm kev ua kom cov viscosity ntawm cov cawv. Sedimentation tshwm sim thaum cov khoom hnyav dua hauv cov cawv nyob rau hauv qab vim lub ntiajteb txawj nqus. Los ntawm kev ua kom cov viscosity ntawm cov cawv, CMC tuaj yeem ua rau qeeb qeeb ntawm cov khoom no, tiv thaiv sedimentation. Qhov no yog ua tiav los ntawm cov khoom thickening ntawm CMC, uas ua rau kom cov viscosity ntawm cov cawv thiab tsim ib qho chaw ruaj khov rau cov khoom.

Tiv thaiv Haze Formation

CMC kuj tseem tuaj yeem tiv thaiv kev ua qias tuaj hauv cawv los ntawm kev khi rau thiab tshem tawm cov proteins thiab lwm yam tsis ruaj khov uas tuaj yeem ua rau muaj huab cua phem. Haze tsim tshwm sim thaum cov khoom tsis ruaj khov hauv cov cawv txiv hmab tuaj ua ke thiab tsim cov khoom sib sau ua ke, ua rau pom huab cua. CMC tuaj yeem tiv thaiv kev ua qias tuaj los ntawm kev khi rau cov khoom tsis ruaj khov no thiab tiv thaiv lawv los ntawm kev sib sau ua ke. Qhov no yog ua tiav los ntawm electrostatic attraction ntawm qhov tsis zoo them carboxyl pawg ntawm CMC thiab cov amino acids zoo hauv cov protein.

Kev txhim kho ntawm Mouthfeel thiab Texture

Ntxiv nrog rau kev ruaj khov ntawm cov cawv, CMC tuaj yeem txhim kho lub qhov ncauj thiab kev ntxhib los mos ntawm cov cawv. CMC muaj qhov hnyav molecular thiab qib siab ntawm kev hloov pauv, uas ua rau muaj kuab heev thiab zoo li gel zoo nkauj. Qhov kev ntxhib los mos no tuaj yeem txhim kho lub qhov ncauj ntawm cov cawv thiab tsim kom muaj kev ntxhib los mos thiab ntau dua velvety. Qhov sib ntxiv ntawm CMC tuaj yeem txhim kho lub cev thiab viscosity ntawm cov cawv, ua rau lub qhov ncauj puv thiab nplua nuj.

Noj

Qhov ntau npaum ntawm CMC hauv cawv yog ib qho tseem ceeb uas yuav tsum tau xav txog, vim tias ntau dhau ntawm CMC tuaj yeem ua rau muaj kev cuam tshuam tsis zoo rau cov txiaj ntsig ntawm cov cawv. Kev pom zoo ntawm CMC hauv cawv yog nyob ntawm ntau yam, nrog rau hom cawv, qhov zoo ntawm cov cawv, thiab cov khoom xav tau. Feem ntau, qhov concentration ntawm CMC nyob rau hauv wine ranges ntawm 10 mus rau 100 mg / L, nrog ntau dua concentrations siv rau liab cawu cub thiab qis concentrations siv rau dawb wine.

Hauv cov ntsiab lus, CMC yog cov cuab yeej tseem ceeb rau kev txhim kho qhov zoo thiab ruaj khov ntawm cawv. CMC tuaj yeem ruaj khov cawv, tiv thaiv sedimentation thiab haze tsim, thiab txhim kho lub qhov ncauj thiab kev ntxhib los mos ntawm cawv. Cov txheej txheem ntawm CMC hauv cawv yog raws li nws lub peev xwm los tsim cov txheej txheem tiv thaiv ib puag ncig cov tshuaj tsis ruaj khov, ua kom cov viscosity ntawm cov cawv txiv hmab, thiab tshem tawm cov khoom tsis ruaj khov uas tuaj yeem ua rau haze tsim. Kev pom zoo ntawm CMC hauv cawv yog nyob ntawm ntau yam, thiab yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev cuam tshuam tsis zoo rau cov txiaj ntsig ntawm cov cawv. Kev siv CMC hauv kev lag luam cawv tau nrov zuj zus vim nws cov txiaj ntsig thiab kev siv yooj yim.
