Nws belongs rau tsev neeg Fabaceae thiab feem ntau cog rau nws cov taum zoo li pods uas muaj cov noob guar. Ntawm no yog ib qho piv txwv ntawm guar gum:

Kev sib xyaw:

• Polysaccharide Structure: Guar gum yog tsim los ntawm cov hlua ntev ntawm galactomannans, uas yog ib hom carbohydrate uas muaj mannose thiab galactose units txuas ua ke.
• Chemical Structure: Cov khoom tseem ceeb ntawm cov pos hniav yog cov kab hluav taws xob ntawm mannose units txuas los ntawm β (1 → 4) glycosidic bonds, nrog galactose sab chains txuas rau qee qhov mannose units.

Properties thiab yam ntxwv:

1. Thickening Agent: Guar gum yog dav siv los ua tus neeg sawv cev thickening nyob rau hauv ntau yam lag luam vim nws muaj peev xwm ua kom cov viscosity thiab sib xws ntawm cov kua.
2. Hydrocolloid: Nws raug cais raws li hydrocolloid, txhais tau tias nws muaj peev xwm tsim cov gel los yog kua nplaum thaum tov nrog dej.
3. Dej-Soluble: Guar gum yog soluble hauv dej txias thiab kub, tsim cov kua dej khov txawm tias tsis tshua muaj siab.
4. Stabilizer thiab Emulsifier: Ntxiv nrog rau qhov tuab, guar cov pos hniav kuj tuaj yeem ua tus stabilizer thiab emulsifier hauv cov khoom noj, pab tiv thaiv cov khoom sib cais thiab txhim kho kev ntxhib los mos.
5. Zaj duab xis-Forming Properties: Guar cov pos hniav tuaj yeem tsim cov yeeb yaj kiab hloov tau yooj yim thaum ziab, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov xws li cov txheej txheem thiab cov yeeb yaj kiab.
6. Cov ntsiab lus calorie tsawg: Nws muaj calories tsawg thiab tsis muaj txiaj ntsig zoo rau cov ntsiab lus caloric ntawm cov zaub mov lossis dej haus.

Kev siv thiab kev siv:

• Kev lag luam khoom noj khoom haus: Guar gum feem ntau yog siv los ua cov thickening, stabilizing, thiab emulsifying tus neeg sawv cev nyob rau hauv ntau yam khoom noj khoom haus, nrog rau cov kua ntses, hnav khaub ncaws, khoom noj siv mis, ci, thiab dej haus.
• Pharmaceuticals: Hauv kev lag luam kws tshuaj, guar cov pos hniav yog siv los ua cov binder thiab disintegrant nyob rau hauv cov ntsiav tshuaj formulations, nrog rau ib tug thickening neeg sawv cev nyob rau hauv cov kua thiab semi-solid formulations.
• Tshuaj pleev ib ce thiab Kev Kho Tus Kheej: Guar cov pos hniav yog siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej xws li tshuaj pleev ib ce, cream, tshuaj zawv plaub hau, thiab tshuaj txhuam hniav ua cov thickener, stabilizer, thiab emulsifier.
• Cov ntawv thov kev lag luam: Guar cov pos hniav muaj ntau yam kev siv hauv kev lag luam, suav nrog hauv textile printing, ntawv tsim, kev tsim khoom tawg, thiab roj thiab roj drilling raws li kev hloov kho viscosity thiab thickener.

Kev nyab xeeb thiab kev txiav txim siab:

• Guar gum feem ntau lees paub tias muaj kev nyab xeeb (GRAS) rau kev noj los ntawm cov cai tswj hwm, suav nrog US Food and Drug Administration (FDA).
• Thaum pom tias muaj kev nyab xeeb rau tib neeg feem ntau, cov tib neeg uas muaj qee yam kev ua xua los yog rhiab heev rau legumes, xws li taum thiab txiv laum huab xeeb, yuav muaj kev cuam tshuam tsis zoo rau cov pos hniav.
• Raws li nrog rau cov khoom noj khoom haus ntxiv, guar cov pos hniav yuav tsum tau siv rau hauv cov khoom tsim nyog thiab cov qauv tsim kom ntseeg tau tias cov khoom muaj kev nyab xeeb thiab zoo.

guar cov pos hniav yog ntau yam khoom xyaw nrog ntau yam kev siv hauv ntau yam lag luam vim nws cov thickening zoo heev, stabilizing, thiab emulsifying zog. Nws muaj nuj nqis rau nws lub hauv paus chiv keeb, kev yooj yim ntawm kev siv, thiab kev ua tau zoo hauv kev txhim kho kev ntxhib los mos thiab zoo ntawm cov khoom noj, tshuaj, thiab cov khoom siv tshuaj pleev ib ce.
