I-Gellan Gum CAS: 71010-52-1 Umhlinzeki Womkhiqizi

I-Gellan Gum iyisithasiselo se-agar kanye ne-gelling agent, futhi iwusizo ezinhlobonhlobo ze-immobilizing matricies. I-gellan gum isetshenziswa njenge-gelling agent, i-thickener, kanye ne-stabilizer kuma-cosmetic preparation. I-Gellan Gum iyisithasiselo esitholakala ngokubiliswa kwe-microorganism sphingomonas elodea. Ushukela oyingxenye yi-glucose, i-glucuronic acid, kanye ne-rhamnose ngesilinganiso sama-molecule esingu-2:1:1, esixhunyaniswe ndawonye ukunikeza isakhiwo esiyinhloko esakhiwe yi-linear tetrasaccharine repeating unit. Ukubuyiselwa okuqondile kuveza isithasiselo ngendlela yaso yemvelo noma ephezulu ye-acyl lapho kukhona khona ama-acyl substituents amabili, i-acetate kanye ne-glycate. Ama-gel avela kulolo hlobo ayanwebeka futhi ahlangene. Ukubuyiselwa ngemva kokususwa kwe-acetylation kususa amaqembu e-acyl ukuze kutholakale ifomu le-acyl eliphansi; lawo ma-gel aqinile futhi ayaphuka. Ngokuvamile, isithasiselo se-gellan esiphezulu se-acyl esihlakazekile emanzini siyavuvukala ukuze sakhe ukumiswa okujiyile futhi lapho sifudumala, silahlekelwa yi-viscosity yaso lapho simanziswa khona. I-gellan gum ephansi incibilika kancane emanzini abandayo futhi incibilika ngokushisa kufike ku-70°c noma ngaphezulu. Ukwakheka kwe-gellan kwenzeka lapho kuphola futhi kusabela nama-ion, ikakhulukazi ama-ion e-calcium. I-gellan gum iyazwela kuma-ion. Ukusetshenziswa kufaka phakathi ukugcwaliswa kwezithelo ebhikawozi, ama-confectioneries, ama-icing, imikhiqizo yobisi, iziphuzo, kanye nokugqoka.
