Sodium Alginate

 

Sodium Alginate, tseem hu ua algin lossis alginic acid sodium ntsev, yog ib txwm tshwm sim anionic polysaccharide. Nws yog feem ntau muab rho tawm los ntawm cov phab ntsa ntawm tes ntawm cov xim av algae (xws li kelp thiab loj heev kelp) thiab yog ib qho ntawm cov khoom siv ntau tshaj plaws hauv seaweed. Nws cov molecules yog tsim los ntawm ob monomers, -D-mannuronic acid thiab -L-guluronic acid, txuas los ntawm 1,4-glycosidic bonds.

Cov mis mos molecular: (C6H7O6Na)n

CAS Nr .: 9005-38-3

 

 

Ntau daim ntawv thov ntawm alginate yog raws li cov yam ntxwv tseem ceeb hauv qab no

 

Gel-kev muaj peev xwm: Nov yog nws cov khoom tseem ceeb tshaj plaws. Thaum cov tshuaj alginate tuaj rau hauv kev sib cuag nrogdivalent cations(feem ntauCalcium ions Ca²⁺), ionic cross ceev ceev - txuas tshwm sim, tsim ib lub thermally irreversible gel nrog peb -seem network qauv. Cov txheej txheem no yog me me, ceev, thiab feem ntau tshwm sim ntawm chav tsev kub.

 

Thickening thiab stabilizing cuam tshuam: Raws li hydrophilic colloid, nws tuaj yeem ua kom cov viscosity ntawm aqueous daws thiab ua raws li emulsifying thiab ua npuas ncauj stabilizer.

 

Zaj duab xis- tsim muaj peev xwm: Nws tuaj yeem tsim cov yeeb yaj kiab hloov tau yooj yim, pob tshab.

 

Biocompatibility thiab kev nyab xeeb: Nws tsis yog - tshuaj lom, biodegradable, thiab feem ntau lees paub tias muaj kev nyab xeeb (GRAS), dav siv hauv zaub mov thiab chaw muag tshuaj.

 

PH rhiab heev: Nyob rau hauv acidic tej yam kev mob (tsawg pH), alginate undergoes protonation, nce viscosity los yog txawm precipitating; nws tseem ruaj khov nyob rau hauv alkaline tej yam kev mob.

 

 

Kev lag luam khoom noj (Feem ntau siv los ua zaub mov ntxiv E401)

• Gelled Khoom noj khoom haus:Kev tsim cov jellyfish, khoom qab zib gels, thiab spherification khoom (piv txwv li, "flavor bursts" lossis "caviar" hauv molecular gastronomy).
• Thickening & Stabilizing Agent:Siv hauv cov dej khov nab kuab (kom inhibit ice crystal kev loj hlob), yogurt, kua ntses, thiab hnav khaub ncaws los txhim kho kev ntxhib los mos thiab ruaj khov.
• Dej Retention Agent:Ntxiv rau lub khob cij thiab pasta kom khaws cov dej noo thiab ua kom lub neej ntev.

 

Pharmaceuticals & Biotechnology

• Hnav khaub ncaws:Calcium alginate hnav khaub ncaws absorbs qhov txhab exudate thiab tsim ib tug mos mos, moist gel uas txhawb kev kho mob thiab tso cai rau tsis muaj - raug tshem tawm.
• Kev xa tshuaj:Dav siv los ua matrix rau kev tswj hwm - tso tshuaj xa tawm, tshwj xeeb tshaj yog rau txoj hnyuv- lub hom phiaj xa khoom vim nws ruaj khov hauv cov kua qaub hauv plab thiab solubility hauv plab hnyuv.
• Cell Encapsulation & Tissue Engineering:Nws qhov mob me, ion-induced gelation yog qhov zoo tagnrho rau kev nkag mus rau cov hlwb, cov protein, lossis tshuaj. Nws yog cov khoom tseem ceeb rau bioinks hauv 3D bioprinting thiab cov ntaub so ntswg scaffolds.

 

Lwm Cov Kev Siv Hluav Taws Xob

• Textile luam ntawv:Ua hauj lwm raws li ib tug thickener nyob rau hauv cov ntaub ntawv luam pastes.
• Kev Kho Tus Kheej & Tshuaj pleev ib ce:Siv cov tshuaj txhuam hniav, daim npog ntsej muag, thiab cov tshuaj nplaum ua cov gelling thiab stabilizing tus neeg sawv cev.
• Ib puag ncig:Siv los ua ib qho adsorbent rau hnyav hlau ions hauv kev kho dej khib nyiab.
