CAS: 9005-37-2|Propyleneglycol Alginate

Propylene glycol alginate, hu ua PGA, belongs rau alginate esters. Ib feem ntawm cov carboxyl pawg ntawm alginic acid yog esterified los ntawm propylene glycol (ntau tshaj 90%), thiab cov seem 10% ntawm cov carboxyl pawg yog dawb los yog neutralized los ntawm alkali. Propylene glycol alginate yog tsim los ntawm alginic acid muab rho tawm los ntawm ntuj seaweed los ntawm kev sib sib zog nqus ua. Cov tsos mob yog dawb los yog daj-dawb hmoov, yuav luag tsis muaj ntxhiab los yog me ntsis aromatic, tasteless, hygroscopic, yooj yim soluble nyob rau hauv dej txias los yog dej sov los tsim ib tug viscous colloidal tov. Insoluble hauv methanol, ethanol, benzene thiab lwm yam organic solvents. Tus txheeb ze ntom ntom 1.46. Thaum rhuab mus rau 155 degree, cov xim hloov xim av, rau carbonization ntawm 22{19}} degree, thiab tshauv ntawm 400 degree. Lub viscosity yog tas li thaum cov ntsiab lus yog 1% lossis qis dua. Cov tshuaj aqueous yog ruaj khov hauv qab 0 degree, tab sis cov viscosity txo qis ntawm 100 degree. Ntxiv cov kua qaub tuaj yeem ua kom nws cov viscosity. Nws muaj zog acid tsis kam tab sis tsis zoo alkali tsis kam, thiab nws cov viscosity ruaj khov rau lub sijhawm ntev hauv pH ntau ntawm 3 txog 4. Nws yog qhov ruaj khov tshaj plaws ntawm pH 2 txog 3, thiab yooj yim decomposes ntawm pH> 6.5. Yog li ntawd, nws muaj qhov zoo ntawm cov protein stabilizing nyhuv nyob rau hauv acidic tej yam kev mob, thiab kuj muaj ib tug tshwj xeeb ua npuas ncauj stabilizing nyhuv. Txawm li cas los xij, yog tias cov khoom no tau khaws cia ntawm qhov kub siab dua rau lub sijhawm ntev, nws yuav maj mam dhau los ua cov khoom tsis zoo. Nws tuaj yeem siv tau rau hauv cov tshuaj tsw qab los pab emulsify rog thiab diffuse tsw. Cov tshuaj yog 0.8%. Nws tseem tuaj yeem siv rau hauv seasonings rau cov khoom noj nqaij ntawm qhov ntau npaum ntawm 0.5%, thiab hauv cov txiv hmab txiv ntoo khov ntawm qhov ntau npaum li 1%.

Kev siv: stabilizer; thickener; emulsifier; foaming tus neeg sawv cev; txuj lom extraction hnyav.
