Yintoni umahluko phakathi kweCMC kunye ne-xanthan gum

1. Isishwankathelo kunye neMvelaphi

1.1.Carboxymethyl Cellulose (CMC):

I-CMC iphuma kwiselulosi eyenziwe ngokuguqula ngokwekhemikhali iselulosi yendalo efunyenwe kwiindonga zeeseli zesityalo, ezifana nentlaka yeplanga okanye imicu yomqhaphu. Ngenkqubo ebizwa ngokuba yi-carboxymethylation, amaqela e-hydroxyl kumqolo we-cellulose athatyathelwa indawo ngamaqela e-carboxymethyl, nto leyo eyenza ukuba i-soluble emanzini kwaye ikwazi ukwenza izisombululo ze-viscous.

 

1.2.Xanthan Gum:

I-Xanthan gum yi-microbial polysaccharide eveliswa yi-bacterium Xanthomonas campestris ngexesha lokubiliswa kweglucose, i-sucrose, okanye i-lactose. Emva kokuvutshelwa, i-gum iyancipha (ngokuqhelekileyo isebenzisa i-isopropyl alcohol), yomiswe, kwaye igaywe ibe ngumgubo ocolekileyo.

 

1.3.Umahluko ongundoqo:

I-CMC ithathwe kwisityalo kwaye iguqulwe ngokwemichiza, ngelixa i-xanthan gum isenziwa nge-microbially synthesized ngokuvundiswa. Lo mahluko uchaphazela ukwakheka kwawo, ukusebenza kwawo, kunye noqwalaselo lolawulo (umzekelo, kwiilebhile zokutya okuphilayo).

 

2. Ulwakhiwo lweMichiza

2.1.Isakhiwo seCMC:

I-CMC inomqolo we-cellulose ohambelanayo kunye namaqela e-carboxymethyl endaweni. Ubume bayo beekhemikhali bufana ngokufanayo, kwaye i-degree of substitution (DS)-oko kukuthi, inani eliqhelekileyo lamaqela e-carboxymethyl ngeyunithi ye-anhydroglucose-inokulawulwa ukuguqula ukunyibilika kwayo kunye ne-viscosity.

 

2.2.Xanthan Gum Ulwakhiwo:

I-Xanthan gum inesakhiwo esinzima ngakumbi. Iqukethe i-cellulose-like backbone kunye ne-trisaccharide side chain ehlanganiswe ne-mannose kunye ne-glucuronic acid. Esi sakhiwo sisodwa sinegalelo kwizinto eziphawulekayo zokucheba kunye nokuzinza.

 

2.3.Umahluko ongundoqo:

I-CMC inesakhiwo esilula, esine-linear, ngelixa i-xanthan gum ibonisa isakhiwo se-branched, esibangela uzinzo olungcono phantsi kweemeko ezahlukeneyo ezifana ne-pH, ubushushu, kunye ne-shear force.

 

3.IiPropati eziSebenzayo

Ipropati	CMC	Xanthan Gum
Ukunyibilika	Ukunyibilika kakhulu emanzini	Ukunyibilika kakhulu emanzini
pH Uzinzo	Izinzile ngokungathathi hlangothi ukuya kwi-alkaline kancinane pH	Izinzile kakhulu kuluhlu olubanzi lwe-pH
UNyamezelo lobushushu	Bunovelwano kubushushu obuphezulu (ukonakala kwi>80°C)	Uzinzo oluhle kakhulu lwe-thermal
Shear Behaviour	I-Newtonian (i-viscosity ihlala ingatshintshi)	Ukucheba-ukunciphisa (i-viscosity iyancipha ngokucheba)
Umkhenkce-Thaw uzinzo	Imbi ukuya kumodareyitha	Egqwesileyo

Umahluko oPhambili:

I-Xanthan gum iqhuba ngcono phantsi kweemeko zokucutshungulwa ngokugqithisileyo, iyenza ilunge ngakumbi kwiimveliso ezifuna imijikelo yokunyibilika komkhenkce, ukuvala inzala, okanye ukwahluka kwe-pH.

 

4. Izicelo

4.1.CMC Isebenzisa:

Ishishini lokutya: Isetyenziswa kwi-ayisikrimu, izinto ezibhakiweyo, iisosi, izinxibo, kunye neziselo ukunika i-viscosity, i-mouthfeel kunye nokuxhoma.

Pharmaceuticals: Isebenza njengesibophelelo kwiipilisi kunye ne-thickener kulwelo oluthathwa ngomlomo.

Izithambiso: Isetyenziswa kwizinto zokuthambisa kunye nentlama yamazinyo ukwenzela ukuhambelana nokuzinza.

Imizi-mveliso: Baqeshwe kulwelo lokomba, ukuveliswa kwephepha, kunye nezicoci.

 

4.2.Xanthan Gum Usebenzisa:

Ishishini lokuTya: Isetyenziswa kakhulu ekubhakeni okungenagluten, ukunxitywa kwesaladi, iisosi, kunye nezinye iindlela zobisi zokujiya kunye nokuzinzisa.

I-Pharmaceuticals: Isebenza njenge-arhente yokuxhoma kwiisyrups kunye ne-topical formulations.

Izithambiso: Zizinzisa i-emulsion kwaye zongeza i-viscosity kwiimveliso zokunyamekela ulusu.

Umzi-mveliso: Usetyenziswa ekuphuculweni kokufunyanwa kwe-oli, ezolimo, kunye neepeyinti.

 

4.3.Umahluko ongundoqo:

Nangona zombini ziguquguqukayo, i-xanthan gum ikhethwa kwizicelo ezinzima kakhulu ngenxa yokuqina kwayo phantsi kweemeko zoxinzelelo.

 

5. I-Allergenicity kunye ne-Labeling

Zombini i-CMC kunye ne-xanthan gum zibonwa njengekhuselekile (GRAS) yi-US FDA kwaye zamkelwe ukuba zisetyenziswe kukutya kwihlabathi jikelele. Nangona kunjalo:

 

I-CMC ithathwa njenge-hypoallergenic kwaye ifanelekile kwizicelo ezininzi zokutya.

 

I-Xanthan Gum, nangona ikhuselekile, ivundisiwe kwiswekile enokuthi ithathwe kwizinto eziqhelekileyo ezifana nombona okanye isoyi. Abantu abane-allergies eqatha okanye ababuthathaka banokusabela ngaphandle kokuba kusetyenziswe iinguqulelo ezingenayo i-allergen.

 

Kwimveliso ye-organic okanye ecocekileyo-ileyibhile, i-xanthan gum ngamanye amaxesha yamkelwa ngakumbi ngenxa yemvelaphi yayo "yendalo yokuvubela", ngelixa i-CMC inokuthintelwa ngenxa yokuba iguqulwe ngokuzenzekelayo.
