Umahluko phakathi kweSodium CMC, Xanthan Gum kunye neGuar Gum

I-sodium carboxymethyl cellulose (CMC), i-xanthan gum, kunye ne-guar gum zonke zisetyenziswa ngokubanzi ii-hydrocolloids kunye nezicelo ezahlukeneyo kumacandelo okutya, amayeza, ezokuthambisa, kunye nakwezoshishino. Ngelixa babelana ngokufana ngokuhambelana nokuqina kwabo, ukuzinzisa, kunye neempawu ze-gelling, kukho ukungafani okuphawulekayo kwizakhiwo zabo zeekhemikhali, imithombo, ukusebenza, kunye nokusetyenziswa. Makhe sihlolisise umahluko phakathi kwezi hydrocolloids zintathu:

1. Ulwakhiwo lweMichiza:

• I-Sodium Carboxymethyl Cellulose (CMC): I-CMC yinto ephuma emanzini e-cellulose, eyi-polysaccharide eyenziwe ngokuphindaphindiweyo kweeyunithi ze-glucose. Amaqela e-Carboxymethyl (-CH2-COOH) angeniswa kwi-cellulose backbone ngokuphendula kwe-etherification, ukubonelela ukunyibilika kwamanzi kunye neempawu ezisebenzayo kwipolymer.
• Xanthan Gum: Xanthan gum yi microbial polysaccharide eveliswa ngokubiliswa yi bacteria Xanthomonas campestris. Iqukethe iiyunithi eziphindaphindiweyo ze-glucose, i-mannose, kunye ne-glucuronic acid, kunye namatyathanga asecaleni aqukethe i-mannose kunye ne-glucuronic acid. I-Xanthan gum iyaziwa ngobunzima bayo obuphezulu bemolekyuli kunye neempawu ezizodwa ze-rheological.
• IGuar Gum: Itshungama yeGuar ivela kwi-endosperm yeguar bean (Cyamopsis tetragonoloba). Iqulunqwe ngegalactomannan, i-polysaccharide ebandakanya ikhonkco leyunithi yeeyunithi ze-mannose kunye ne-galactose side chain. I-Guar gum inobunzima obuphezulu bemolekyuli kwaye yenza izisombululo ze-viscous xa i-hydrated.

2. Umthombo:

• I-CMC ithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zesityalo.
• I-Xanthan gum iveliswa nge-microbial fermentation ye-carbohydrates yi-Xanthomonas campestris.
• I-Guar gum ifumaneka kwi-endosperm ye-guar bean.

3. Imisebenzi:

• I-Sodium Carboxymethyl Cellulose (CMC):
  • Isebenza njenge-thickener, stabilizer, binder, kunye nefilimu-yangaphambili kwizicelo ezahlukeneyo.
  • Yenza iijeli ezingafihliyo kunye ne-thermal reversible.
  • Ibonisa ukuziphatha kokuhamba kwe-pseudoplastic.
• Xanthan Gum:
  • Imisebenzi njenge-thickener, stabilizer, emulsifier, kunye ne-arhente yokumisa.
  • Ibonelela ngolawulo olubalaseleyo lwe-viscosity kunye nokuziphatha kokucheba.
  • Yenza izisombululo ze-viscous kunye neegels ezizinzileyo.
• IGuar Gum:
  • Isebenza njenge-thickener, stabilizer, binder, kunye ne-emulsifier.
  • Ibonelela nge-viscosity ephezulu kunye nokuziphatha kwe-pseudoplastic flow.
  • Yenza izisombululo ze-viscous kunye neegels ezizinzileyo.

4. Ukunyibilika:

• I-CMC inyibilika kakhulu emanzini abandayo nashushu, yenza izisombululo ezicacileyo nezibonakalayo.
• I-Xanthan gum iyanyibilika emanzini abandayo kunye nashushu, kunye ne-dispersibility egqwesileyo kunye neempawu zokumanzisa.
• I-Guar gum ibonisa ukunyibilika okulinganiselweyo emanzini abandayo kodwa isasazeke kakuhle emanzini ashushu ukwenza izisombululo ze-viscous.

5. Uzinzo:

• Izisombululo ze-CMC zizinzile kuluhlu olubanzi lwe-pH kunye neemeko zobushushu.
• Izisombululo ze-Xanthan gum zizinzile kuluhlu olubanzi lwe-pH kwaye ziyamelana nobushushu, ukucheba, kunye ne-electrolytes.
• Izisombululo zeGuar gum zinokubonisa uzinzo oluncitshisiweyo kwi-pH ephantsi okanye kubukho boxinzelelo oluphezulu lwetyuwa okanye i-calcium ion.

6. Usetyenziso:

• I-Sodium Carboxymethyl Cellulose (CMC): Isetyenziswa kwiimveliso zokutya (umz., iisosi, iilokhwe, indawo yokubhaka), amayeza (umz., iipilisi, ukumiswa), izinto zokuthambisa (umz., iikhrimu, izinto zokuthambisa), amalaphu, kunye nezinto ezisetyenziswa kwimizi-mveliso (umz., iphepha, izicoci. ).
• Xanthan Gum: Isetyenziswa kakhulu kwiimveliso zokutya (umzekelo, isaladi yokunxiba, iisosi, ideri), amayeza (umz., ukumiswa, ukhathalelo lomlomo), izithambiso (umz., iikhrimu, intlama yamazinyo), ulwelo lwe-oyile yokomba, kunye nezinye izinto ezisetyenziswa kwimizi-mveliso.
• IGuar Gum: Isetyenziswa kwiimveliso zokutya (umz., izinto ezibhakiweyo, imveliso yobisi, iziselo), amayeza (umz., iipilisi, izinto ezixhonyiweyo), izinto zokuthambisa (umz., iikhrimu, izinto zokuthambisa), ushicilelo lwempahla olulukiweyo, kunye nolwelo olwenziwa ngolwelo olwenziwa ngolwelo olusebenza ngamanzi kushishino lweoyile.

Isiphelo:

Ngelixa i-sodium carboxymethyl cellulose (i-CMC), i-xanthan gum, kunye ne-guar gum babelana ngokufana okuthile ekusebenzeni kwabo kunye nokusetyenziswa njenge-hydrocolloids, baphinde babonise umahluko ocacileyo kwizakhiwo zabo zeekhemikhali, imithombo, iipropati kunye nokusetyenziswa. Ukuqonda lo mahluko kubalulekile ekukhetheni eyona hydrocolloid ifanelekileyo kwizicelo ezithile kumashishini ahlukeneyo. I-hydrocolloid nganye inikezela ngeenzuzo ezizodwa kunye neempawu zokusebenza ezinokuthi zilungelelaniswe ukuhlangabezana neemfuno zeendlela ezahlukeneyo kunye neenkqubo.
