Kusiyana pakati pa Sodium CMC, Xanthan chingamu ndi Guar chingamu

Sodium carboxymethyl cellulose (CMC), xanthan chingamu, ndi guar chingamu onse amagwiritsidwa ntchito kwambiri hydrocolloids ndi ntchito zosiyanasiyana m'magawo chakudya, mankhwala, zodzoladzola, ndi mafakitale. Ngakhale amagawana zofananira potengera kukhuthala kwawo, kukhazikika, ndi kukhazikika kwawo, palinso kusiyana kwakukulu pamapangidwe awo amankhwala, magwero, magwiridwe antchito, ndi kagwiritsidwe ntchito kawo. Tiyeni tiwone kusiyana pakati pa ma hydrocolloids atatu awa:

1. Kapangidwe ka Chemical:

• Sodium Carboxymethyl Cellulose (CMC): CMC ndi chochokera m'madzi chosungunuka cha cellulose, chomwe ndi polysaccharide yopangidwa ndi mayunitsi a shuga obwerezabwereza. Magulu a Carboxymethyl (-CH2-COOH) amalowetsedwa pamsana wa cellulose kudzera muzochita za etherification, kupereka kusungunuka kwamadzi ndi magwiridwe antchito ku polima.
• Xanthan chingamu: Xanthan chingamu ndi microbial polysaccharide yopangidwa kudzera mu nayonso mphamvu ndi bakiteriya Xanthomonas campestris. Amakhala ndi mayunitsi obwerezabwereza a glucose, mannose, ndi glucuronic acid, okhala ndi maunyolo am'mbali okhala ndi mannose ndi zotsalira za glucuronic acid. Xanthan chingamu imadziwika chifukwa cha kulemera kwake kwa maselo komanso mawonekedwe apadera a rheological.
• Guar chingamu: Guar chingamu amachokera ku endosperm ya guar nyemba (Cyamopsis tetragonoloba). Amapangidwa ndi galactomannan, polysaccharide yopangidwa ndi mzere wozungulira wamagulu a mannose okhala ndi unyolo wam'mbali wa galactose. Guar chingamu imakhala ndi kulemera kwakukulu kwa ma molekyulu ndipo imapanga mayankho owoneka bwino akakhala ndi hydrate.

2. Gwero:

• CMC imachokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose.
• Xanthan chingamu amapangidwa kudzera mu nayonso mphamvu ya ma carbohydrate ndi Xanthomonas campestris.
• Guar chingamu imachokera ku endosperm ya nyemba za guar.

3. Ntchito:

• Sodium Carboxymethyl cellulose (CMC):
  • Amagwira ntchito ngati thickener, stabilizer, binder, ndi film-former mu ntchito zosiyanasiyana.
  • Amapanga ma gels owonekera komanso osinthika motenthetsa.
  • Imawonetsa machitidwe a pseudoplastic flow.
• Xanthan Gum:
  • Imagwira ntchito ngati thickener, stabilizer, emulsifier, ndi kuyimitsa wothandizira.
  • Amapereka kuwongolera kwamakayendedwe abwino kwambiri komanso kumeta ubweya wa ubweya.
  • Amapanga mayankho a viscous ndi ma gels okhazikika.
• Guar Gum:
  • Imagwira ntchito ngati thickener, stabilizer, binder, ndi emulsifier.
  • Amapereka kukhuthala kwakukulu komanso khalidwe la pseudoplastic flow.
  • Amapanga mayankho a viscous ndi ma gels okhazikika.

4. Kusungunuka:

• CMC imasungunuka kwambiri m'madzi ozizira komanso otentha, ndikupanga mayankho omveka bwino komanso owoneka bwino.
• Xanthan chingamu ndi sungunuka m'madzi ozizira ndi otentha, ndi dispersibility kwambiri ndi hydration katundu.
• Guar chingamu imawonetsa kusungunuka pang'ono m'madzi ozizira koma imamwazika bwino m'madzi otentha kuti ipange mayankho a viscous.

5. Kukhazikika:

• Mayankho a CMC ndi okhazikika pamitundu yambiri ya pH ndi kutentha.
• Mayankho a Xanthan chingamu ndi okhazikika pamitundu yambiri ya pH ndipo samamva kutentha, kumeta ubweya, ndi ma electrolyte.
• Mayankho a Guar chingamu atha kuwonetsa kukhazikika kwapang'onopang'ono pa pH yotsika kapena pamaso pa mchere wambiri kapena ayoni a calcium.

6. Mapulogalamu:

• Sodium Carboxymethyl cellulose (CMC): Amagwiritsidwa ntchito mu zakudya (mwachitsanzo, sauces, mavalidwe, bakery), mankhwala (mwachitsanzo, mapiritsi, suspensions), zodzoladzola (mwachitsanzo, creams, lotions), nsalu, ndi mafakitale ntchito (mwachitsanzo, mapepala, zotsukira ).
• Xanthan chingamu: Amagwiritsidwa ntchito kwambiri muzakudya (mwachitsanzo, ma saladi, sosi, mkaka), mankhwala (monga kuyimitsidwa, chisamaliro chamkamwa), zodzola (monga zopakapaka, zotsukira mano), madzi akubowola mafuta, ndi ntchito zina zamakampani.
• Guar Gum: Amagwiritsidwa ntchito muzakudya (mwachitsanzo, zowotcha, mkaka, zakumwa), mankhwala (mwachitsanzo, mapiritsi, zoyimitsidwa), zodzola (monga mafuta opaka, mafuta odzola), kusindikiza nsalu, ndi madzi opangira ma hydraulic fracturing m'makampani amafuta.

Pomaliza:

Ngakhale sodium carboxymethyl cellulose (CMC), xanthan chingamu, ndi guar chingamu zimagawana zofananira mu magwiridwe antchito awo ndi ntchito ngati ma hydrocolloids, amawonetsanso kusiyana kwakukulu pamapangidwe awo, magwero, katundu, ndi ntchito. Kumvetsetsa kusiyana kumeneku ndikofunikira pakusankha hydrocolloid yoyenera kwambiri pakugwiritsa ntchito m'mafakitale osiyanasiyana. Hydrocolloid iliyonse imapereka maubwino apadera ndi magwiridwe antchito omwe amatha kukonzedwa kuti akwaniritse zofunikira zamitundu yosiyanasiyana ndi njira.
