1.Xanthan chingamu ndi polysaccharide yolemera kwambiri ya molekyulu yomwe imapangidwa ndi polymer kuchokera ku unit yomweyi ndi 5 shuga wa Molecular monga unit.Chigawo chilichonse chimakhala ndi mamolekyu awiri a shuga, mamolekyu awiri a mannose ndi molekyu imodzi ya glucuronic acid.Unyolo wake waukulu umapangidwa ndi β-Glucose wolumikizidwa ndi 1,4-glycosidic bond.Mapangidwe a mamolekyu awiri a glucose ndi ofanana ndi a cellulose.Pali mamolekyu awiri a mannose ndi molekyulu imodzi ya glucuronic acid pa C3 ya shuga kuti apange unyolo wam'mbali.Pali magulu a pyruvic acid ndi carboxylic acid pambali pa unyolo wam'mbali.Chifukwa unyolo wake wam'mbali uli ndi magulu a acidic, umapereka ma polyanions mu njira yamadzimadzi, ndikupanga mawonekedwe atatu amtundu wa xanthan chingamu: unyolo wam'mbali ndi anions umayenda unyolo waukulu kuti upangike mawonekedwe a helical, ndipo mamolekyu amapanga mawonekedwe opindika awiri. helix ndi ma hydrogen bond, pomwe mawonekedwe a helical omwe ali ndi zingwe ziwiri amasungidwa ndi zomangira zofooka zopanda mgwirizano, kupanga "super bonded riboni helical polima".Kuchita kwake kwapadera kumagwirizana ndi pyruvic acid yomwe ili nayo.Nthawi zambiri, asidi wa pyruvic mu xanthan chingamu angagwiritsidwe ntchito kuyeza momwe amagwirira ntchito.

2.Typical rheological katundu, mkulu mamasukidwe akayendedwe otsika ndende, kutentha kukana, asidi kukana, alkali kukana, enzymatic hydrolysis kukana, ngakhale, solubility, kubalalitsidwa, kusunga madzi.

3.Solubility sungunuka m'madzi, osasungunuka mu ethanol (ot-42).Tengani 300ml yamadzi kuti muyese kupanga gel osakaniza, ikani mu beaker ya 400ml, itenthe mpaka 80 ℃, ndikuwonjezera 1.5g ya zitsanzo ndi 1.5g ya ufa wa carrageenan pansi pa kugwedeza kwakukulu kwa makina.Limbikitsani mpaka yankho lipangidwe, ndiyeno pitirizani kuyambitsa 3chemicalbook0min.Pakusakaniza, kutentha kwa madzi sikuyenera kukhala kotsika kuposa 60 ℃, kusiya kusakaniza, ndi kuziziritsa kutentha kwambiri kuposa 2H.Kutentha kumatsika kuposa 40 ℃, mphira wolimba ngati gel ayenera kupangidwa, koma gel oterowo sangapangidwe ngati chitsanzocho chikugwiritsidwa ntchito m'malo mwa 1% yowongolera njira yokonzedwa ndi njira yomweyo ndi carrageenan.

Kugwiritsa ntchito

1. Mu kubowola mafuta makampani, 0,5% xanthan zomatira njira angathe kusunga mamasukidwe akayendedwe a madzi ozikidwa pobowola madzimadzi ndi kulamulira rheological katundu wake, kotero kuti mamasukidwe akayendedwe othamanga kwambiri pozungulira pang'ono kwambiri, amene amapulumutsa kwambiri kuwononga mphamvu. .Komabe, imasunga mamasukidwe apamwamba mu gawo lobowola losasunthika, lomwe limathandizira kupewa kugwa kwa khoma la chitsime ndikuwongolera kudula miyala m'chitsime.

2. M'makampani a zakudya, ndi bwino kuposa zowonjezera zakudya zomwe zilipo monga gelatin, CMC, chingamu cha m'nyanja ndi pectin.Kuonjezera 0,2% - 1% ku madzi a zipatso kumapangitsa kuti madzi a zipatso azikhala ndi mgwirizano wabwino, kukoma kwabwino, ndikuwongolera kulowa ndi kutuluka;Monga chowonjezera cha mkate, chemicalbook imatha kupanga mkate kukhala wokhazikika, wosalala, kusunga nthawi ndikuchepetsa mtengo;Kugwiritsa ntchito 0,25% pakuyika mkate, kudzaza chakudya ndi icing kumatha kuwonjezera kukoma ndi kununkhira, kusalaza gulu lazogulitsa, kukulitsa moyo wa alumali, ndikuwongolera kukhazikika kwa zinthuzo kuti zitenthe ndi kuzizira;Muza mkaka, kuwonjezera 0.1% - 0.25% ku ayisikilimu kumatha kugwira ntchito yabwino yokhazikika;Itha kupereka kuwongolera kwamakayendedwe abwino muzakudya zamzitini, ndipo imatha kusintha gawo la wowuma.Gawo limodzi la xanthan chingamu limatha kusintha magawo 3-5 a wowuma.Pa nthawi yomweyo, xanthan chingamu wakhala ankagwiritsa ntchito maswiti, zokometsera, chakudya mazira ndi madzi chakudya.
