Cov khoom xyaw tseem ceeb ntawm cov kua nplaum yog cov tshuaj macromolecular ntawm polysaccharides lossis cov proteins.
Lub ntsiab muaj pes tsawg leeg ntawm polysaccharide cov pos hniav yog monosaccharides thiab lawv cov derivatives. Cov qauv tshuaj yog macromolecular polysaccharide tsim los ntawm monosaccharide units. Qhov sib txawv ntawm kev ua haujlwm ntawm xanthan gum zaub mov qib yog tshwm sim los ntawm ntau hom monosaccharides, sib txawv polymerization degrees, sib txawv kev sib txuas thiab kev npaj ntawm cov piam thaj, thiab qhov sib txawv ntawm cov pab pawg hydroxyl ntawm chav tsev. Lawv feem ntau xav txog hauv cov ntsiab lus ntawm solubility, viscosity, cov yam ntxwv ntawm cov kua dej, cov gel tov stability rau acid thiab alkali thiab kub. Lub peev xwm gelling thiab gel lub zog, gel tov rau lwm cov electrolytes, compatibility, pseudoplasticity, synergy thiab complementarity ntawm ntau yam polysaccharides ntawm polysaccharide cov pos hniav kuj cuam tshuam.
Protein-zoo li xanthan cov pos hniav qib zaub mov, feem ntau muaj cov amino acids, vim nws hom, kom muaj nuj nqis thiab spatial qauv kev npaj ncaj qha cuam tshuam thiab txwv nws cov khoom ua haujlwm.
