Daim ntawv thov ntawm E466 Khoom noj khoom haus Additive hauv Food Industry

E466, tseem hu ua carboxymethyl cellulose (CMC), yog cov khoom noj ntxiv uas tau siv dav hauv kev lag luam khoom noj. CMC yog ib qho derivative ntawm cellulose, uas yog lub ntsiab yam ntxwv ntawm cov nroj tsuag cell phab ntsa. CMC yog cov dej-soluble polymer uas muaj txiaj ntsig zoo hauv kev txhim kho kev ntxhib los mos, ruaj khov, thiab ua haujlwm ntawm cov khoom noj khoom haus. Kab lus no yuav tham txog cov khoom, kev siv, thiab cov txiaj ntsig ntawm CMC hauv kev lag luam khoom noj.

Cov khoom ntawm Carboxymethyl Cellulose

CMC yog cov dej-soluble polymer uas tau los ntawm cellulose. Nws yog ib qho hnyav molecular hnyav uas muaj carboxymethyl thiab hydroxyl pawg. Qhov degree ntawm kev hloov pauv (DS) ntawm CMC yog hais txog qhov nruab nrab ntawm cov carboxymethyl pawg ib chav tsev anhydroglucose ntawm cellulose qaum. Tus nqi DS yog qhov tseem ceeb uas cuam tshuam rau cov khoom ntawm CMC, xws li nws cov solubility, viscosity, thiab thermal stability.

CMC muaj cov qauv tshwj xeeb uas tso cai rau nws cuam tshuam nrog dej molecules thiab lwm yam khoom xyaw. CMC molecules tsim ib tug peb-dimensional network ntawm hydrogen bonds thiab electrostatic cuam tshuam nrog dej molecules thiab lwm yam khoom noj khoom haus Cheebtsam, xws li cov proteins thiab lipids. Cov qauv network no txhim kho kev ntxhib los mos, ruaj khov, thiab ua haujlwm ntawm cov khoom noj khoom haus.

Kev siv Carboxymethyl Cellulose hauv Kev Lag Luam Khoom Noj

CMC yog ntau yam khoom noj khoom haus ntxiv uas tuaj yeem siv rau hauv ntau yam khoom noj, xws li cov khoom ci, khoom noj siv mis, kua ntses, hnav khaub ncaws, thiab dej haus. CMC yog ntxiv rau cov khoom noj khoom haus ntawm qhov ntau ntawm 0.1% mus rau 1.0% los ntawm qhov hnyav, nyob ntawm seb cov khoom noj tshwj xeeb thiab cov khoom xav tau.

CMC yog siv rau hauv cov khoom noj khoom haus rau ntau daim ntawv thov, suav nrog:

1. Thickening thiab viscosity tswj: CMC nce viscosity ntawm cov khoom noj khoom haus, uas pab txhim kho lawv cov kev ntxhib los mos, qhov ncauj, thiab kev ruaj ntseg. CMC kuj tseem pab tiv thaiv kev sib cais thiab daws cov khoom xyaw hauv cov khoom noj khoom haus, xws li cov khaub ncaws hnav thiab cov kua ntses.
2. Emulsification thiab stabilization: CMC ua raws li emulsifying thiab stabilizing tus neeg sawv cev los ntawm kev tsim cov txheej tiv thaiv ib ncig ntawm cov tee roj lossis roj hauv cov khoom noj. Cov txheej no tiv thaiv cov tee dej los ntawm coalescing thiab sib cais, uas tuaj yeem txhim kho lub txee lub neej thiab kev xav ntawm cov khoom noj khoom haus, xws li mayonnaise thiab ice cream.
3. Kev khi dej thiab khaws cia noo noo: CMC muaj peev xwm ua kom dej ruaj khov, uas pab txhim kho cov dej noo thiab txee lub neej ntawm cov khoom ci thiab lwm yam khoom noj. CMC kuj tseem pab tiv thaiv kev tsim cov dej khov hauv cov khoom noj khov, xws li cov dej khov thiab cov khoom qab zib khov.

Cov txiaj ntsig ntawm Carboxymethyl Cellulose hauv Kev Lag Luam Khoom Noj

CMC muab ntau yam txiaj ntsig rau cov khoom noj khoom haus, suav nrog:

1. Txhim kho kev ntxhib los mos thiab lub qhov ncauj zoo: CMC txhim kho cov viscosity thiab gelation ntawm cov khoom noj khoom haus, uas tuaj yeem txhim kho lawv qhov kev ntxhib los mos thiab qhov ncauj. Qhov no tseem tuaj yeem txhim kho kev paub txog kev paub ntawm cov neeg siv khoom.
2. Txhim khu kev ruaj ntseg thiab txee lub neej: CMC pab tiv thaiv kev sib cais, kho, thiab lwj ntawm cov khoom noj khoom haus, uas tuaj yeem txhim kho lawv lub txee lub neej thiab txo cov khoom pov tseg. Qhov no tseem tuaj yeem txo qhov xav tau ntawm cov khoom noj khoom haus thiab lwm yam khoom ntxiv.
3. Tus nqi zoo: CMC yog cov khoom noj khoom haus uas muaj txiaj ntsig zoo uas tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom noj khoom haus yam tsis tau nce lawv cov nqi. Qhov no ua rau nws nyiam cov khoom noj khoom haus uas xav tau los txhim kho lawv cov khoom thaum tswj tus nqi sib tw.
