Carboxymethylcellulose (CMC) uye xanthan chingamu ese ari hydrophilic colloids anowanzoshandiswa muindasitiri yechikafu seanokora, anosimbisa, uye gelling agents. Kunyangwe ivo vachigovana zvimwe zvinoshanda zvakafanana, zvinhu zviviri izvi zvakasiyana zvakanyanya pamabviro, chimiro, uye mashandisiro.
Carboxymethylcellulose (CMC):
1. Kwakabva uye chimiro:
Kunobva: CMC inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro. Kazhinji inotorwa kubva muhuni pulp kana machira ekotoni.
Chimiro: CMC ndeye cellulose inotorwa ne carboxymethylation ye cellulose mamorekuru. Carboxymethylation inosanganisira kuiswa kwecarboxymethyl mapoka (-CH2-COOH) mune cellulose chimiro.
2. Solubility:
CMC inonyungudika mumvura, ichigadzira mhinduro yakajeka uye ine viscous. Iyo dhigirii yekutsiva (DS) muCMC inokanganisa kunyungudika kwayo uye zvimwe zvivakwa.
3. Basa:
Kukora: CMC inoshandiswa zvakanyanya seyakakora mumiriri mune dzakasiyana siyana zvigadzirwa zvekudya, zvinosanganisira sosi, madhirezi uye zvigadzirwa zvemukaka.
Kudzikamisa: Inobatsira kudzikamisa emulsions uye kumiswa, kudzivirira kupatsanurwa kwezvinhu.
Kuchengeta Mvura: CMC inozivikanwa nekugona kwayo kuchengetedza mvura, zvichibatsira kuchengetedza hunyoro muzvikafu.
4. Application:
CMC inowanzoshandiswa muindasitiri yechikafu, mishonga uye zvizorwa. Muindasitiri yechikafu, inoshandiswa muzvigadzirwa zvakaita seaizikirimu, zvinwiwa uye zvinhu zvakabikwa.
5. Kurambidzwa:
Kunyangwe CMC ichishandiswa zvakanyanya, kushanda kwayo kunogona kukanganiswa nezvinhu zvakaita sepH uye kuvapo kwemamwe maion. Inogona kuratidza kukanganisa kwekuita pasi pemamiriro e acidic.
Xanthan chingamu:
1. Kwakabva uye chimiro:
Kwakabva: Xanthan chingamu imicrobial polysaccharide inogadzirwa nekuviriswa kwemacarbohydrates nebhakitiriya Xanthomonas campestris.
Chimiro: Chimiro che xanthan chingamu chine cellulose musana ine trisaccharide parutivi cheni. Iine glucose, mannose uye glucuronic acid zvikamu.
2. Solubility:
Xanthan chingamu inonyungudika zvakanyanya mumvura, ichigadzira viscous mhinduro pane yakaderera concentration.
3. Basa:
Kukora: Kufanana neCMC, xanthan chingamu inhengo inoshanda yekukora. Inopa chikafu chimiro chakatsetseka uye elastic.
Kugadzikana: Xanthan gum inogadzirisa kumiswa uye emulsions, kudzivirira kuparadzaniswa kwechikamu.
Gelling: Mune mamwe maapplication, xanthan chingamu inobatsira mukugadzira gel.
4. Application:
Xanthan chingamu ine huwandu hwakasiyana hwekushandisa muindasitiri yechikafu, kunyanya mukubheka-isina gluten, mapfekero esaladhi uye masosi. Inoshandiswawo mumaindasitiri akasiyana siyana.
5. Kurambidzwa:
Mune mamwe maapplication, kunyanya kushandisa xanthan chingamu kunogona kukonzera kunamira kana "runny" manyorerwo. Kungwarira kudzora dosage kunogona kudikanwa kuti udzivise zvisingadiwe zvinyorwa zvemavara.
Enzanisa:
1. Kwakabva:
CMC inotorwa kubva ku cellulose, chirimwa-based polymer.
Xanthan chingamu inogadzirwa kuburikidza ne microbial fermentation.
2.Chemical chimiro:
CMC ndeye cellulose derivative inogadzirwa ne carboxymethylation.
Xanthan chingamu ine yakaomesesa dhizaini ine trisaccharide parutivi cheni.
3. Solubility:
Zvese CMC uye xanthan chingamu zvinonyungudika nemvura.
4. Basa:
Ose ari maviri anoita seanokora uye anodzikamisa, asi anogona kunge aine zvishoma zvakasiyana mhedzisiro pakugadzirwa.
5. Application:
CMC uye xanthan chingamu inoshandiswa mumhando dzakasiyana dzechikafu uye maindasitiri ekushandisa, asi sarudzo pakati pavo inogona kuenderana nezvinodiwa chaizvo zvechigadzirwa.
6. Kurambidzwa:
Imwe neimwe ine painogumira, uye sarudzo pakati pazvo inogona kutsamira pazvinhu zvakaita sepH, dosi, uye magadzirirwo anodiwa echigadzirwa chekupedzisira.
Kunyangwe CMC uye xanthan chingamu zvine mashandisirwo akafanana se hydrocolloids muindasitiri yechikafu, anosiyana pamabviro, chimiro, uye mashandisiro. Sarudzo pakati peCMC uye xanthan chingamu zvinoenderana nezvinodiwa chaizvo zvechigadzirwa, uchifunga nezvezvinhu zvakaita sepH, dosi uye zvinodiwa zvemavara. Zvinhu zviviri izvi zvinopa zvakanyanya kuumbwa, kugadzikana uye kunaka kwese kwemhando dzakasiyana dzekudya uye zvigadzirwa zvemaindasitiri.
