I-Gellan Gum CAS: 71010-52-1 Umthengisi woMvelisi

I-Gellan Gum sisithathi-ndawo se-agar kunye ne-arhente ye-gelling, kwaye iluncedo kwiindidi ezahlukeneyo ze-immobilization matricies. I-gellan gum isetyenziswa njenge-arhente ye-gelling, i-thickener, kunye ne-stabilizer kumalungiselelo e-cosmetic. I-Gellan Gum yi-gum efunyenwe ngokubiliswa kwe-microorganism sphingomonas elodea. Iiswekile eziyinxalenye yi-glucose, i-glucuronic acid, kunye ne-rhamnose kumlinganiselo we-molecular we-2:1:1, zidibene kunye ukunika isakhiwo esiphambili esiqulathe iyunithi ephindaphindayo ye-tetrasaccharine. Ukubuyiswa ngqo kuvelisa i-gum kwifom yayo yendalo okanye ephezulu ye-acyl apho kukho khona izinto ezimbini ze-acyl substituents, i-acetate kunye ne-glycerate. Ii-gels ezivela kuloo fom ziyanwebeka kwaye zihlangene. Ukubuyiswa emva kokususwa kwe-acetylation kususwe amaqela e-acyl ukuze kukhutshwe ifom ye-acyl ephantsi; ezo gels ziqinile kwaye zibuthathaka. Ngokubanzi, i-acyl gellan gum ephezulu esasazeke emanzini iyadumba ukuze yenze i-suspension etyebileyo kwaye xa ifudunyezwa, ilahlekelwa yi-viscosity yayo xa ifuthwa. I-gellan gum esezantsi inyibilika kancinci emanzini abandayo kwaye inyibilika ngokufudumeza ukuya kuma-70°c nangaphezulu. I-gelation yenzeka xa ipholile kwaye isabela kwii-ion, ikakhulu ii-calcium ions. I-gellan gum inovelwano kwii-ion. Ukusetyenziswa kwayo kubandakanya ukuzaliswa kweziqhamo zebhakari, ii-confectioneries, ii-icing, iimveliso zobisi, iziselo kunye neengubo.
