Taw qhia rau gellan cov pos hniav hmoov
Gellan cov pos hniavyog dej-soluble, siab molecular hnyav anionic exopolysaccharide ua los ntawm microbial fermentation ntawmSpingomonas elodea(yav tas losPseudomonas elodea). Pom tau nyob rau xyoo 1970, nws tau dhau los ua ib qho ntawm cov hydrocolloids siab tshaj plaws hauv cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab biotechnology industries.
Chemically, gellan cov pos hniav yog linear tetrasaccharide repeating unit muaj li ntawmD-glucose, D-glucuronic acid, thiab L-rhamnosenyob rau hauv ib tug 2: 1: 1 molar ratio. Repeat unit qauv yog: →3)- -D-Glcp-(1→4)- -D-GlcpA-(1→4)- -D-Glcp-(1→4)- -R →2} polysaccharide muaj acyl substituents - glyceryl (qhov nruab nrab, ib qho kev rov ua dua tshiab) thiab acetyl (ib qho ntawm txhua ob qhov rov ua dua tshiab).
1. Tsawg Acyl vs High Acyl Gellan Gum
- Low Acyl Gellan Gum (LA):Ua los ntawm alkaline deacylation ntawm haiv neeg polysaccharide. Cov ntaub ntawv ruaj khov, tsis yog elastic, nkig, thiab thermally irreversible gels (zoo ib yam li agar). Zoo tagnrho rau confectionery, khoom noj khoom haus, thiab microbial media.
- High Acyl Gellan Gum (HA):Retains natural acyl pawg. Cov ntaub ntawv mos, elastic, thiab thermally reversible gels (zoo ib yam li gelatin). Qhov zoo tshaj plaws rau cov khoom noj siv mis, khoom qab zib, kua ntses, thiab cov khoom uas yuav tsum tau muaj kev ntxhib los mos.
