Gellan Gum CAS: 71010-52-1 Chaw Tsim Khoom

Gellan Gum yog ib qho agar hloov thiab gelling agent, thiab muaj txiaj ntsig zoo rau ntau yam kev immobilization matricies. gellan gum yog siv ua tus neeg sawv cev gelling, thickener, thiab stabilizer hauv kev npaj khoom kom zoo nkauj. Gellan Gum yog ib qho gum tau los ntawm kev fermentation ntawm cov kab mob sphingomonas elodea. cov suab thaj yog glucose, glucuronic acid, thiab rhamnose hauv qhov sib piv molecular ntawm 2: 1: 1, txuas ua ke los muab cov qauv tseem ceeb uas muaj ib qho linear tetrasaccharine repeating unit. Kev rov qab ncaj qha ua rau cov gum hauv nws daim ntawv haiv neeg lossis siab acyl uas muaj ob qho acyl substituents, acetate thiab glycerate, muaj. gels los ntawm daim ntawv ntawd yog elastic thiab cohesive. Kev rov qab tom qab deacetylation muaj cov pab pawg acyl raug tshem tawm kom ua rau daim ntawv acyl qis; cov gels muaj zog thiab brittle. feem ntau, cov acyl gellan gum siab dispersed hauv dej swells los ua ib qho tuab suspension thiab thaum cua sov, nws poob nws cov viscosity thaum hydration. Cov roj hmab acyl gellan qis tsuas yog yaj ib nrab hauv dej txias thiab yaj los ntawm cua sov rau 70 ° c lossis ntau dua. gelation tshwm sim thaum txias thiab tshuaj tiv thaiv nrog ions, feem ntau yog calcium ions. Cov roj hmab gellan yog rhiab rau ions. siv suav nrog cov khoom qab zib txiv hmab txiv ntoo, khoom qab zib, icings, cov khoom noj mis nyuj, dej haus, thiab coatings.
