1.Xanthan gum yog cov khoom hnyav molecular polysaccharide uas yog polymerized los ntawm tib chav tsev nrog 5 Molecular qab zib ua ib chav tsev.Txhua chav tsev yog tsim los ntawm 2 molecules ntawm qabzib, 2 molecules ntawm mannose thiab 1 molecule ntawm glucuronic acid.Nws cov saw tseem ceeb yog tsim los ntawm β-Glucose txuas nrog 1,4-glycosidic daim ntawv cog lus.Cov qauv ntawm 2 molecules ntawm qabzib yog tib yam li cov cellulose.Muaj 2 molecules ntawm mannose thiab 1 molecule ntawm glucuronic acid ntawm C3 ntawm qabzib los tsim ib sab saw.Muaj pyruvic acid thiab carboxylic acid sab pawg ntawm sab saw.Vim tias nws cov saw hlau sab muaj cov kua qaub, nws nthuav tawm polyanions hauv cov kua dej, tsim cov qauv peb-theem peb-dimensional ntawm xanthan cov pos hniav: cov saw sab nrog anions cua cov saw tseem ceeb los tsim cov qauv helical, thiab cov molecules tsim ob txoj hlua khi. helix los ntawm hydrogen bonds, thaum lub sij hawm ob stranded helical qauv yog tswj los ntawm tsis muaj zog tsis muaj covalent bonds, tsim ib tug "super bonded ribbon helical polymer".Nws qhov kev ua tau zoo tshwj xeeb yog cuam tshuam nrog pyruvic acid nws muaj.Feem ntau, cov ntsiab lus pyruvic acid hauv xanthan cov pos hniav tuaj yeem siv los ntsuas nws qhov kev ua tau zoo.

2.Tshuaj rheological zog, siab viscosity ntawm tsawg concentration, kub tsis kam, acid kuj, alkali tsis kam, enzymatic hydrolysis kuj, compatibility, solubility, dispersion, dej tuav.

3.Solubility soluble nyob rau hauv dej, insoluble nyob rau hauv ethanol (ot-42).Siv 300ml dej rau qhov kev sim tsim gel, muab tso rau hauv 400ml beaker, preheat nws mus rau 80 ℃, thiab ntxiv 1.5g ntawm cov qauv thiab 1.5g ntawm hmoov carrageenan nyob rau hauv khaus mechanical stirring.Do kom txog thaum cov tshuaj tsim, thiab tom qab ntawd txuas ntxiv do rau 3chemicalbook0min.Thaum sib tov, dej kub yuav tsum tsis txhob qis dua 60 ℃, tsis txhob sib tov, thiab txias ntawm chav tsev kub rau ntau tshaj 2H.Thaum qhov kub thiab txias qis dua 40 ℃, cov roj hmab tawv zoo li gel yuav tsum tsim, tab sis cov gel zoo li no yuav tsis tsim yog tias tsuas yog cov qauv siv xwb es tsis txhob siv 1% kev daws teeb meem los ntawm tib txoj kev nrog carrageenan.

Daim ntawv thov

1. Hauv kev lag luam roj drilling, 0.5% xanthan kua nplaum tuaj yeem tswj tau cov viscosity ntawm cov dej-raws li drilling kua thiab tswj nws cov khoom rheological, kom lub viscosity ntawm high-speed rotating ntsis me me, uas zoo heev txuag lub zog noj. .Txawm li cas los xij, nws tuav cov viscosity siab nyob rau hauv qhov zoo li qub drilling qhov, uas ua lub luag haujlwm hauv kev tiv thaiv kev tawg ntawm phab ntsa dej thiab ua kom yooj yim txiav cov pob zeb tawm ntawm lub qhov dej.

2. Hauv kev lag luam khoom noj, nws zoo dua li cov khoom noj uas twb muaj lawm xws li gelatin, CMC, seaweed gum thiab pectin.Ntxiv 0.2% - 1% rau cov kua txiv hmab txiv ntoo ua rau cov kua txiv hmab txiv ntoo muaj adhesion zoo, saj zoo, thiab tswj kev nkag mus thiab ntws;Raws li ib qho ntxiv ntawm qhob cij, chemicalbook tuaj yeem ua rau lub khob cij ruaj khov, du, txuag lub sijhawm thiab txo nqi;Siv 0.25% nyob rau hauv qhob cij khoom, khoom noj khoom haus filling thiab icing yuav ua rau kom lub saj thiab tsw, smooth lub koom haum ntawm cov khoom, ncua lub txee lub neej, thiab txhim kho cov stability ntawm cov khoom kom sov thiab khov;Hauv cov khoom noj siv mis, ntxiv 0.1% - 0.25% rau cov dej khov tuaj yeem ua lub luag haujlwm ruaj khov zoo;Nws tuaj yeem muab cov viscosity tswj tau zoo hauv cov zaub mov kaus poom, thiab tuaj yeem hloov tau ib feem ntawm cov hmoov txhuv nplej siab.Ib feem ntawm xanthan cov pos hniav tuaj yeem hloov 3 ~ 5 feem ntawm cov hmoov txhuv nplej siab.Nyob rau tib lub sijhawm, xanthan cov pos hniav kuj tau siv dav hauv cov khoom qab zib, khoom noj khoom haus, khoom noj khov thiab kua zaub mov.
