Ọdịiche dị n'etiti sodium CMC, Xanthan Gum na Guar Gum

Sodium carboxymethyl cellulose (CMC), xanthan gum, na guar gum bụ hydrocolloids niile na-eji ngwa dị iche iche na nri, ọgwụ, ịchọ mma na ngalaba mmepụta ihe. Ọ bụ ezie na ha na-ekerịta ụfọdụ myirịta n'ihe gbasara ihe ha na-eme ka ha sie ike, na-eme ka ahụ sie ike na gelling, enwekwara ọdịiche pụtara ìhè na nhazi kemịkalụ, isi mmalite, ọrụ ha na ngwa ha. Ka anyị nyochaa ọdịiche dị n'etiti hydrocolloids atọ a:

1. Ọdịdị kemịkalụ:

  • Sodium Carboxymethyl Cellulose (CMC): CMC bụ ihe soluble mmiri nke cellulose, nke bụ polysaccharide nke mejupụtara nkeji glucose ugboro ugboro. A na-ewebata otu Carboxymethyl (-CH2-COOH) n'ime ọkpụkpụ azụ cellulose site na mmeghachi omume etherification, na-enye solubility mmiri na akụrụngwa arụ ọrụ na polymer.
  • Xanthan Gum: Xanthan chịngọm bụ microbial polysaccharide nke a na-emepụta site na gbaa ụka site na nje Xanthomonas campestris. Ọ mejupụtara nkeji glucose, mannose na glucuronic acid ugboro ugboro, yana ụdọ akụkụ nwere mannose na glucuronic acid residues. A maara Xanthan chịngọm maka ịdị arọ molekụla ya dị elu yana njirimara rheological pụrụ iche.
  • Guar Gum: A na-enweta chịngọm site na endosperm nke guar bean (Cyamopsis tetragonoloba). Ihe mejupụtara ya bụ galactomannan, polysaccharide nke nwere eriri ahịrị nke nkeji mannose nwere eriri akụkụ galactose. Guar chịngọm nwere ibu molekụla dị elu ma na-emepụta ngwọta viscous mgbe mmiri gbara ya mmiri.

2. Isi mmalite:

  • CMC sitere na cellulose, polymer eke dị na mgbidi cell osisi.
  • A na-emepụta Xanthan chịngọm site na mkpụrụ ndụ ihe nketa nke carbohydrates site na Xanthomonas campestris.
  • A na-enweta chịngọm site na endosperm nke agwa agwa.

3. Ọrụ:

  • Sodium Carboxymethyl Cellulose (CMC):
    • Na-arụ ọrụ dị ka thickener, stabilizer, ihe nkedo, na onye na-eme ihe nkiri na ngwa dị iche iche.
    • Ụdị gels transperent na thermally reversible.
    • Na-egosiputa omume mgbaba pseudoplastic.
  • Xanthan chịngọm:
    • Na-arụ ọrụ dị ka onye na-agba agba, stabilizer, emulsifier na onye na-akwụsịtụ.
    • Na-enye njikwa viscosity dị mma na omume ịkpacha mma.
    • Na-etolite ngwọta viscous na gels kwụsiri ike.
  • Guar chịngọm:
    • Ọ na-arụ ọrụ dị ka onye na-agba agba, stabilizer, ihe nkedo, na emulsifier.
    • Na-enye elu viscosity na pseudoplastic eruba omume.
    • Na-etolite ngwọta viscous na gels kwụsiri ike.

4. Solubility:

  • CMC na-agbaze nke ukwuu na mmiri oyi na mmiri ọkụ, na-emepụta ngwọta doro anya na viscous.
  • Xanthan chịngọm bụ soluble na mmiri oyi na mmiri ọkụ, nwere ezigbo dispersibility na hydration Njirimara.
  • Guar gum na-egosipụta oke solubility na mmiri oyi mana ọ na-agbasa nke ọma na mmiri ọkụ iji mepụta ngwọta viscous.

5. Nkwụsi ike:

  • Ihe ngwọta CMC kwụsiri ike n'ọtụtụ pH na ọnọdụ okpomọkụ.
  • Ihe ngwọta xanthan chịngọm kwụsiri ike n'ofe pH dị obosara ma na-eguzogide okpomọkụ, shiee, na electrolytes.
  • Ngwọta chịngọm nwere ike igosipụta nkwụsi ike dị ala na pH dị ala ma ọ bụ na ọnụnọ nnu dị elu ma ọ bụ ion calcium.

6. Ngwa:

  • Sodium Carboxymethyl Cellulose (CMC): A na-eji ngwaahịa nri (dịka ọmụmaatụ, sauces, mgbakwasa, ebe a na-eme bred), ọgwụ (dịka ọmụmaatụ, mbadamba, nkwusioru), ihe ịchọ mma (dịka, ude, lotions), textiles, na ngwa ụlọ ọrụ mmepụta ihe (dịka ọmụmaatụ, akwụkwọ, detergents). ).
  • Xanthan Gum: A na-eji ya eme ihe na ngwaahịa nri (dịka ọmụmaatụ, akwa salad, sauces, mmiri ara ehi), ọgwụ (dịka ọmụmaatụ, nkwusioru, nlekọta ọnụ), ihe ịchọ mma (dịka, ude, ntacha eze), mmiri mmiri na-egwupụta mmanụ, na ngwa ụlọ ọrụ ndị ọzọ.
  • Guar Gum: A na-eji ngwaahịa nri (dịka ọmụmaatụ, ngwaahịa esi, mmiri ara ehi, ihe ọṅụṅụ), ọgwụ (dịka ọmụmaatụ, mbadamba, nkwusioru), ihe ịchọ mma (dịka ọmụmaatụ, creams, lotions), mbipụta textile, na mmiri mmiri na-agbaji hydraulic na ụlọ ọrụ mmanụ.

Mmechi:

Ọ bụ ezie na sodium carboxymethyl cellulose (CMC), xanthan gum, na guar gum na-ekerịta ụfọdụ myirịta na ọrụ ha na ngwa ha dị ka hydrocolloids, ha na-egosipụtakwa ọdịiche dị iche iche na nhazi kemịkalụ, isi mmalite, ihe onwunwe na ojiji ha. Ịghọta ọdịiche ndị a dị mkpa maka ịhọrọ hydrocolloid kachasị mma maka ngwa ngwa dị iche iche na ụlọ ọrụ dị iche iche. Hydrocolloid ọ bụla na-enye uru pụrụ iche na njirimara arụmọrụ nke enwere ike ịhazi ya iji mezuo ihe achọrọ nke usoro na usoro dị iche iche.
