Yintoni umahluko phakathi kwe-CMC kunye nesitatshi?

I-Carboxymethylcellulose (CMC) kunye nesitatshi zombini zii-polysaccharides, kodwa zinezakhiwo ezahlukeneyo, iipropati kunye nokusetyenziswa kwazo.

Ukwakheka kweemolekyuli:

1. I-Carboxymethylcellulose (CMC):

I-Carboxymethylcellulose yi-derivative ye-cellulose, i-polymer ethe ngqo eyenziwe ziiyunithi zeglucose ezidityaniswe zii-β-1,4-glycosidic bonds. Ukuguqulwa kwe-cellulose kubandakanya ukungeniswa kwamaqela e-carboxymethyl nge-etherification, nto leyo evelisa i-carboxymethylcellulose. Iqela le-carboxymethyl lenza i-CMC inyibilike emanzini kwaye linika i-polymer iipropati ezikhethekileyo.

2. Isitatshi:

Isitatshi sisixa seecarbohydrate esakhiwe ziiyunithi zeglucose ezidityaniswe ziibhondi ze-α-1,4-glycosidic. Yipolymer yendalo efumaneka kwizityalo esetyenziswa njengekhompawundi yokugcina amandla. Iimolekyuli zesitatshi ngokubanzi zenziwe ziintlobo ezimbini zeepolymer zeglucose: i-amylose (iitsheyini ezithe tye) kunye ne-amylopectin (izakhiwo zeetsheyini ezinamasebe).

Iimpawu ezibonakalayo:

1. I-Carboxymethylcellulose (CMC):

Ukunyibilika: I-CMC iyanyibilika emanzini ngenxa yokubakho kwamaqela e-carboxymethyl.

Ukuqina: Ibonisa ukuqina okuphezulu kwisisombululo, nto leyo eyenza ukuba ibe luncedo kwiindlela ezahlukeneyo zokusebenza ezifana nokulungisa ukutya kunye namayeza.

Ukucaca: Izisombululo zeCMC zihlala zibonakala ngokucacileyo.

2. Isitatshi:

Ukunyibilika: Isitatshi sendalo asinyibiliki emanzini. Sifuna i-gelatinization (ukufudumeza emanzini) ukuze sinyibilike.

Ukuxinana: I-starch paste ine-viscosity, kodwa ngokubanzi iphantsi kune-CMC.

Ukucaca: Iipasta zesitatshi zihlala zingacacanga, kwaye ubunzulu bokungacacanga bunokwahluka ngokuxhomekeke kuhlobo lwesitatshi.

umthombo:

1. I-Carboxymethylcellulose (CMC):

I-CMC idla ngokwenziwa nge-cellulose evela kwizityalo ezifana ne-pulp yomthi okanye ikotoni.

2. Isitatshi:

Izityalo ezifana nombona, ingqolowa, iitapile kunye nerayisi zityebile kwisitatshi. Sisithako esiphambili kwiintlobo ezininzi zokutya okuqhelekileyo.

Inkqubo yeMveliso:

1. I-Carboxymethylcellulose (CMC):

Ukuveliswa kwe-CMC kubandakanya i-etherification reaction ye-cellulose ene-chloroacetic acid kwi-alkaline medium. Le reaction iphumela ekutshintshweni kwamaqela e-hydroxyl kwi-cellulose ngamaqela e-carboxymethyl.

2. Isitatshi:

Ukukhupha istatshi kubandakanya ukuqhekeza iiseli zezityalo kunye nokwahlula iigranule zestatshi. Istatshi esikhutshiweyo sinokudlula kwiinkqubo ezahlukeneyo, kubandakanya ukuguqulwa kunye nokufakwa kwe-gelatin, ukuze kufunyanwe iipropati ezifunekayo.

Injongo kunye nokusetyenziswa:

1. I-Carboxymethylcellulose (CMC):

Ishishini lokutya: I-CMC isetyenziswa njengesithambisi-zinzisi, isiqinisi kunye nesixubisisi kwiintlobo ngeentlobo zokutya.

Amayeza: Ngenxa yeempawu zayo zokubopha nokuqhekeka, isetyenziswa kwiifomyula zamayeza.

Ukubhola ngeoyile: I-CMC isetyenziswa kulwelo lokubhola ngeoyile ukulawula i-rheology.

2. Isitatshi:

Ishishini lokutya: Isitatshi sesona sixhobo siphambili kwiintlobo ezininzi zokutya kwaye sisetyenziswa njenge-ejenti yokutyeba, i-ejenti yokujiya kunye ne-stabilizer.

Ishishini lempahla elaphu: Isitatshi sisetyenziswa ekwenzeni ubungakanani bempahla elaphu ukuze iqine.

Ishishini lephepha: Isitatshi sisetyenziswa ekwenzeni iphepha ukonyusa amandla ephepha nokuphucula iimpawu zomphezulu.

Nangona i-CMC kunye nesitatshi zombini ziyi-polysaccharides, zinomahluko kwisakhiwo seemolekyuli, iipropati zomzimba, imithombo, iinkqubo zemveliso kunye nokusetyenziswa kwazo. I-CMC inyibilika emanzini kwaye ixinene kakhulu kwaye idla ngokukhethwa kwizicelo ezifuna ezi mpawu, ngelixa istatshi si-polysaccharide eguquguqukayo esetyenziswa kakhulu kwimizi-mveliso yokutya, yelaphu neyephepha. Ukuqonda la mahluko kubalulekile ekukhetheni i-polymer efanelekileyo kwizicelo ezithile zoshishino kunye nezorhwebo.
