Cov khoom noj khoom haus colloids tau nyiam tib neeg txoj kev xav, tshwj xeeb tshaj yog cov kws tshawb fawb txog zaub mov, rau lawv txoj kev nyab xeeb, cov ntsiab lus tshwj xeeb, thiab cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg. Xanthan gum 415 muaj ntau yam kev siv. Nws tuaj yeem siv rau hauv kev lag luam khoom noj xws li zaub mov txias, dej haus, khoom noj siv mis, khoom noj khoom haus, khoom qab zib, starches, khoom qab zib, cawv, khaws cia zaub mov thiab tub yees. Nws kuj tseem siv tau rau hauv tshuaj pleev ib ce, coatings, photosensitive resins, chiv, thiab lwm yam. Foundry, luam yeeb thiab tshuaj industries.
Muaj txog 60 hom pos hniav uas tau tso cai siv thoob ntiaj teb, thiab txog 40 hom pos hniav tau tso cai siv hauv Suav teb. Cov pos hniav uas siv tau ntau tshaj plaws hauv cov khoom noj hauv Suav teb feem ntau suav nrog carrageenan, xanthan gum, guar gum, agar, Gelatin, sodium alginate, locust taum gum thiab konjac gum, thiab lwm yam.
