Kodi pali kusiyana kotani pakati pa CMC ndi xanthan chingamu?

1. Mwachidule ndi Chiyambi

1.1.Carboxymethyl Cellulose (CMC):

CMC ndi chochokera ku cellulose chomwe chimapangidwa ndikusintha ma cellulose achilengedwe omwe amapezeka pamakoma a cellulose, monga zamkati zamatabwa kapena ulusi wa thonje. Kupyolera mu njira yotchedwa carboxymethylation, magulu a hydroxyl pamsana wa cellulose amalowetsedwa ndi magulu a carboxymethyl, kuwapangitsa kukhala osungunuka m'madzi komanso okhoza kupanga mayankho a viscous.

 

1.2 Xanthan Gum:

Xanthan chingamu ndi microbial polysaccharide yopangidwa ndi bakiteriya Xanthomonas campestris panthawi yowitsa shuga, sucrose, kapena lactose. Pambuyo pa kupesa, chingamucho chimayamba ndi mpweya (nthawi zambiri pogwiritsa ntchito mowa wa isopropyl), zowuma, ndi kupukuta kukhala ufa wabwino.

 

1.3.Kusiyana Kwambiri:

CMC ndi chomera chochokera ku zomera ndi kusinthidwa mankhwala, pamene xanthan chingamu ndi microbially synthesized kudzera nayonso mphamvu. Kusiyanaku kumakhudza kapangidwe kawo, kagwiridwe kake, ndi kaganizidwe kawo (mwachitsanzo, pakulemba zakudya zamagulu).

 

2. Kapangidwe ka Mankhwala

2.1.Mapangidwe a CMC:

CMC ili ndi mzere wamsana wa cellulose wokhala ndi magulu olowa m'malo a carboxymethyl. Kapangidwe kake kake kamakhala kofanana, ndipo digiri ya m'malo (DS) - mwachitsanzo, kuchuluka kwamagulu a carboxymethyl pagawo la anhydroglucose-atha kuwongoleredwa kuti asinthe kusungunuka kwake ndi kukhuthala kwake.

 

2.2.Kapangidwe ka Xanthan Gum:

Xanthan chingamu chili ndi dongosolo lovuta kwambiri. Amakhala ndi msana wa cellulose wokhala ndi maunyolo am'mbali a trisaccharide wopangidwa ndi mannose ndi glucuronic acid. Kapangidwe kake kapadera kameneka kamathandizira kumeta ubweya wodabwitsa komanso kukhazikika kwake.

 

2.3.Kusiyana Kwambiri:

CMC ili ndi mawonekedwe osavuta, ozungulira, pomwe xanthan chingamu imakhala ndi nthambi, zomwe zimapangitsa kuti pakhale bata bwino pansi pamikhalidwe yosiyanasiyana monga pH, kutentha, ndi kukameta ubweya.

 

3.Katundu Wantchito

Katundu	CMC	Xanthan Gum
Kusungunuka	Zosungunuka kwambiri m'madzi	Zosungunuka kwambiri m'madzi
Kukhazikika kwa pH	Wosalowerera ndale mpaka pH ya alkaline pang'ono	Chokhazikika kwambiri pamtunda waukulu wa pH
Kulekerera Kutentha	Imamva kutentha kwambiri (kuwonongeka kwa> 80 ° C)	Kukhazikika kwabwino kwamafuta
Makhalidwe a Shear	Newtonian (kukhuthala kumakhalabe kosasintha)	Kumeta ubweya wa ubweya (kukhuthala kumachepa ndi kukameta ubweya)
Kukhazikika kwa Freeze-Thaw	Osauka mpaka pakati	Zabwino kwambiri

Kusiyana Kwakukulu:

Xanthan chingamu imachita bwino kwambiri pakakonzedwa, kupangitsa kuti ikhale yoyenera pazinthu zomwe zimafunikira kuzizira, kutsekereza, kapena kusintha kwa pH.

 

4. Mapulogalamu

4.1.CMC Ntchito:

Makampani a Chakudya: Amagwiritsidwa ntchito mu ayisikilimu, zinthu zowotcha, sosi, mavalidwe, ndi zakumwa kuti apereke mamasukidwe akayendedwe, kutsekemera pakamwa, ndi kuyimitsidwa.

Mankhwala: Amagwira ntchito ngati chomangira m'mapiritsi komanso chowonjezera mu zakumwa zapakamwa.

Zodzoladzola: Amagwiritsidwa ntchito popaka mafuta odzola ndi otsukira mkamwa pofuna kusasinthasintha komanso kukhazikika.

Industrial: Olembedwa ntchito pobowola madzi, kupanga mapepala, ndi zotsukira.

 

4.2.Xanthan Gum Ntchito:

Makampani a Chakudya: Amagwiritsidwa ntchito kwambiri pophika zakudya zopanda gilateni, mavalidwe a saladi, sosi, ndi njira zina za mkaka kuti azikulitsa ndi kukhazikika.

Pharmaceuticals: Imagwira ntchito ngati suspending agent mu syrups ndi topical formulations.

Zodzoladzola: Zimapangitsa kuti emulsion ikhale yokhazikika komanso imapangitsa kuti mafuta aziwoneka bwino pakhungu.

Industrial: Amagwiritsidwa ntchito powonjezera mafuta, ulimi, ndi utoto.

 

4.3.Kusiyana Kwambiri:

Ngakhale kuti zonsezi ndi zosunthika, xanthan chingamu imakondedwa m'mapulogalamu ovuta kwambiri chifukwa cha kulimba mtima pansi pa zovuta.

 

5. Kusamvana ndi Kulemba zilembo

CMC ndi xanthan chingamu nthawi zambiri zimadziwika kuti ndizotetezeka (GRAS) ndi US FDA ndipo zimavomerezedwa kuti zigwiritsidwe ntchito padziko lonse lapansi. Komabe:

 

CMC imatengedwa ngati hypoallergenic ndipo ndiyoyenera kugwiritsa ntchito zakudya zambiri.

 

Xanthan Gum, ngakhale ilinso yotetezeka, imafufuzidwa kuchokera ku shuga omwe atha kutengedwa kuchokera kuzinthu zomwe zimafanana ndi chimanga kapena soya. Anthu omwe ali ndi ziwengo kwambiri kapena zomverera amatha kuchitapo kanthu pokhapokha ngati atagwiritsidwa ntchito mopanda ma allergen.

 

M'zinthu zachilengedwe kapena zoyera, xanthan chingamu nthawi zina imavomerezedwa kwambiri chifukwa cha "kuwira kwachilengedwe", pomwe CMC imatha kupewedwa chifukwa imasinthidwa mopanga.
