Cov khoom ntawm Sodium Carboxymethyl Cellulose
CMC yog cellulose derivative nrog cov piam thaj polymerization degree ntawm 200-500 thiab etherification degree ntawm 0.6-0.7.Nws yog cov hmoov dawb los yog dawb dawb los yog cov tshuaj fiber ntau, tsis muaj ntxhiab thiab hygroscopic.Qib ntawm kev hloov ntawm pawg carboxyl (the degree of etherification) txiav txim siab nws cov khoom.Thaum etherification degree siab dua 0.3, nws yog soluble hauv alkali tov.Lub viscosity ntawm aqueous tov yog txiav txim los ntawm pH thiab degree ntawm polymerization.Thaum lub degree ntawm etherification yog 0.5-0.8, nws yuav tsis precipitate nyob rau hauv acid.CMC yog yooj yim soluble nyob rau hauv dej thiab dhau los ua ib tug pob tshab viscous tov nyob rau hauv dej, thiab nws viscosity txawv nrog cov tshuaj concentration thiab kub.Qhov kub yog ruaj khov hauv qab 60 ° C, thiab viscosity yuav txo qis thaum rhuab mus ntev ntawm qhov kub siab tshaj 80 ° C.
Kev siv ntawm sodium carboxymethyl cellulose
Nws muaj ntau yam haujlwm xws li thickening, suspending, emulsifying thiab stabilizing.Hauv kev tsim cov dej haus, nws yog siv los ua cov kua txiv hmab txiv ntoo rau cov kua txiv hmab txiv ntoo, ua ib qho emulsification stabilizer rau cov dej haus protein thiab ua cov stabilizer rau cov dej haus yogurt.Qhov ntau npaum yog 0.1% -0.5%.
