Xanthan chingamu pakali pano ndiye gel osakaniza kwambiri a bio potengera kukhuthala, kuyimitsidwa, emulsification, komanso kukhazikika padziko lonse lapansi. Kuchuluka kwa magulu a pyruvate kumapeto kwa unyolo wamtundu wa xanthan chingamu kumakhudza kwambiri katundu wake. Xanthan chingamu imakhala ndi mawonekedwe a ma polima a unyolo wautali, koma imakhala ndi magulu ogwira ntchito kuposa ma polima wamba ndipo imawonetsa mawonekedwe apadera pamikhalidwe inayake. Kuphatikizika kwake mu njira yamadzimadzi kumakhala kosiyanasiyana, kumawonetsa mikhalidwe yosiyana mosiyanasiyana.

1. Kuyimitsidwa ndi emulsifying katundu

Xanthan chingamu imakhala ndi kuyimitsidwa kwabwino pa zolimba zosasungunuka ndi madontho amafuta. Ma molekyulu a Xanthan chingamu amatha kupanga ma copolymers omangika kwambiri, kupanga gel osakaniza ngati mawonekedwe a maukonde omwe amatha kuthandizira kusinthika kwa tinthu tating'onoting'ono, madontho, ndi thovu, kuwonetsa kukhazikika kwamphamvu kwa emulsifying komanso kuyimitsidwa kwakukulu.

2. Kusungunuka kwamadzi bwino

Xanthan chingamu imatha kusungunuka mwachangu m'madzi ndipo imakhala ndi kusungunuka kwamadzi bwino. Makamaka sungunuka m'madzi ozizira, amatha kuthetsa processing yovuta komanso yosavuta kugwiritsa ntchito. Komabe, chifukwa cha hydrophilicity yake yamphamvu, ngati madzi akuwonjezeredwa mwachindunji popanda kugwedezeka kokwanira, wosanjikiza wakunja adzayamwa madzi ndi kufalikira mu gel osakaniza, zomwe zidzalepheretsa madzi kulowa mkati ndi kukhudza mphamvu yake. Choncho, iyenera kugwiritsidwa ntchito moyenera. Sakanizani ufa wa xanthan chingamu kapena zowonjezera ufa wouma monga mchere ndi shuga, ndipo pang'onopang'ono muwonjezere ku madzi oyambitsa kuti mupange yankho loti mugwiritse ntchito.

3. Kukhuthala katundu

Thanthwe la Xanthan chingamu lili ndi mawonekedwe otsika komanso kukhuthala kwakukulu (kukhuthala kwa 1% yamadzimadzi amadzimadzi kumafanana ndi nthawi 100 ya gelatin), kupangitsa kuti ikhale yokhuthala bwino.

4. Pseudoplasticity

The xanthan chingamu yankho ali mkulu mamasukidwe akayendedwe pansi malo static kapena otsika kukameta ubweya mikhalidwe, ndi kusonyeza kutsika kwambiri mamasukidwe akayendedwe pansi mikhalidwe kukameta ubweya mkulu, koma kapangidwe maselo amakhalabe osasintha. Pamene mphamvu yometa ubweya imachotsedwa, kukhuthala koyambirira kumabwezeretsedwanso. Ubale pakati pa kukameta ubweya wa ubweya ndi viscosity ndi pulasitiki kwathunthu. Pseudoplasticity ya xanthan chingamu ndi yodziwika kwambiri, ndipo pseudoplasticity iyi ndiyothandiza kwambiri pakukhazikitsa kuyimitsidwa ndi ma emulsions.

5. Kukhazikika kwa kutentha

Kukhuthala kwa xanthan chingamu sikusintha kwambiri ndi kutentha. Nthawi zambiri, ma polysaccharides amasintha kukhuthala chifukwa cha kutentha, koma kukhuthala kwa xanthan chingamu amadzimadzi kumakhalabe kosasinthika pakati pa 10-80 ℃. Ngakhale otsika ndende amadzimadzi mayankho amaonetsa khola mkulu mamasukidwe akayendedwe pa kutentha osiyanasiyana. Kutenthetsa 1% xanthan chingamu solution (yokhala ndi 1% potaziyamu chloride) kuchokera pa 25 ℃ mpaka 120 ℃ imangochepetsa kukhuthala kwake ndi 3%.

6. Kukhazikika kwa acidity ndi alkalinity

Xanthan chingamu yankho ndi wokhazikika kwa acidity ndi zamchere, ndipo mamasukidwe ake mamasukidwe akayendedwe samakhudzidwa pakati pH 5-10. Pali kusintha pang'ono kwa viscosity pamene pH ili yochepa kuposa 4 ndi yaikulu kuposa 11. M'kati mwa pH ya 3-11, chiwerengero chapamwamba komanso chochepa cha viscosity chimasiyana ndi osachepera 10%. Xanthan chingamu imatha kusungunuka mumitundu yosiyanasiyana ya asidi, monga 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid, ndi 25% phosphoric acid. Maxanthan chingamu asidi njira ndi okhazikika kutentha firiji ndipo sasintha khalidwe kwa miyezi ingapo. Xanthan chingamu amathanso kupasuka mu sodium hydroxide njira ndipo thickening katundu. Zotsatira zake zimakhala zokhazikika kutentha kwa chipinda. Xanthan chingamu akhoza kuonongeka ndi oxidants amphamvu monga perchloric acid ndi persulfate, ndi kuwonongeka Iyamba Iyamba ndi kuwonjezeka kutentha.
