Ka ʻokoʻa ma waena o Sodium CMC, Xanthan Gum a me Guar Gum

ʻO ka sodium carboxymethyl cellulose (CMC), xanthan gum, a me ka guar gum he hydrocolloids i hoʻohana nui ʻia me nā noi like ʻole i ka meaʻai, lāʻau lapaʻau, cosmetic, a me nā ʻoihana ʻoihana.ʻOiai kaʻana like lākou i nā ʻano o kā lākou mānoanoa, hoʻopaʻa ʻana, a me nā waiwai gelling, aia kekahi mau ʻokoʻa ʻē aʻe i kā lākou hana kemika, nā kumu, nā hana, a me nā noi.E ʻimi kākou i nā ʻokoʻa o kēia mau hydrocolloids ʻekolu:

1. Hana Kemika:

• ʻO Sodium Carboxymethyl Cellulose (CMC): ʻO ka CMC he mea hoʻoheheʻe wai-soluble o cellulose, ʻo ia ka polysaccharide i haku ʻia me nā ʻāpana glucose hou.Hoʻokomo ʻia nā pūʻulu Carboxymethyl (-CH2-COOH) i ka iwi kuamoʻo cellulose ma o nā hopena etherification, e hāʻawi ana i ka solubility wai a me nā waiwai hana i ka polymer.
• Xanthan Gum: Xanthan gum he microbial polysaccharide i hana ʻia ma o ka fermentation e ka huakini Xanthomonas campestris.Loaʻa iā ia nā ʻāpana hou o ka glucose, mannose, a me ka glucuronic acid, me nā kaulahao ʻaoʻao i loaʻa nā koena mannose a me glucuronic acid.ʻIke ʻia ʻo Xanthan gum no kona kaumaha molekala kiʻekiʻe a me nā waiwai rheological kūʻokoʻa.
• Guar Gum: Loaʻa ʻia ka gum guar mai ka endosperm o ka pī guar (Cyamopsis tetragonoloba).Hoʻokumu ʻia me ka galactomannan, he polysaccharide i loaʻa i kahi kaulahao laina o nā ʻāpana mannose me nā kaulahao ʻaoʻao galactose.He paona molekala kiʻekiʻe ka gum Guar a loaʻa i nā hāʻina viscous ke hoʻomaʻemaʻe ʻia.

2. Puna:

• Loaʻa ʻia ka CMC mai ka cellulose, kahi polymer maoli i loaʻa i loko o nā paia o nā mea kanu.
• Hoʻokumu ʻia ka Xanthan gum ma o ka microbial fermentation o nā kaʻaleʻa e Xanthomonas campestris.
• Loaʻa ka gum guar mai ka endosperm o ka pī guar.

3. Nā hana:

• Sodium Carboxymethyl Cellulose (CMC):
  • Hana ma ke ʻano he mānoanoa, stabilizer, binder, a me ka film-former i nā noi like ʻole.
  • Hoʻokumu i nā gels ʻālohilohi a me ka thermally reversible.
  • Hōʻike i ka hana kahe pseudoplastic.
• Xanthan Gum:
  • Hoʻohana ma ke ʻano he mānoanoa, stabilizer, emulsifier, a me ka mea hoʻomaha.
  • Hāʻawi i ka mana viscosity maikaʻi loa a me ka hana shear-thinning.
  • Hoʻokumu i nā hāʻina viscous a me nā gel paʻa.
• Guar Gum:
  • Hoʻohana ma ke ʻano he mānoanoa, stabilizer, binder, a me emulsifier.
  • Hāʻawi i ka viscosity kiʻekiʻe a me ka hana kahe pseudoplastic.
  • Hoʻokumu i nā hāʻina viscous a me nā gel paʻa.

4. Solubility:

• Hiki ke hoʻoheheʻe ʻia ʻo CMC i ka wai anuanu a me ka wai wela, e hana ana i nā ʻoluʻolu a me ka viscous.
• Hiki ke hoʻoheheʻe ʻia ka Xanthan gum i ka wai anuanu a me ka wai wela, me ka maikaʻi o ka dispersibility a me nā waiwai hydration.
• Hōʻike ka gum Guar i ka hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu akā hoʻopuehu maikaʻi ʻia i loko o ka wai wela e hana i nā haʻina viscous.

5. Paʻa:

• Paʻa nā hoʻonā CMC ma luna o kahi ākea o ka pH a me nā kūlana wela.
• Paʻa ka hoʻonā ʻana o ka Xanthan gum ma kahi ākea pH ākea a kūpaʻa i ka wela, ʻā, a me nā electrolytes.
• Hiki ke hōʻike ʻia nā haʻina Guar gum i ke kūpaʻa haʻahaʻa ma ka pH haʻahaʻa a i ʻole ke alo o nā paʻakai kiʻekiʻe a i ʻole nā ​​​​iona calcium.

6. Nā noi:

• ʻO Sodium Carboxymethyl Cellulose (CMC): Hoʻohana ʻia i nā huahana meaʻai (e laʻa, nā meaʻai, nā lole, nā mea ʻai palaoa), nā lāʻau lapaʻau (e laʻa, nā papa, hoʻokuʻu ʻia), nā mea hoʻonaninani (eg, creams, lotions), textiles, a me nā noi ʻoihana (e laʻa, pepa, detergents. ).
• Xanthan Gum: Hoʻohana nui ʻia i nā huahana meaʻai (e laʻa, nā lole saladi, nā ʻuala, ka waiū), nā lāʻau lapaʻau (e laʻa, hoʻokuʻu ʻia, mālama waha), nā mea hoʻonaninani (eg, creams, toothpaste), wai wili ʻaila, a me nā noi ʻoihana ʻē aʻe.
• Guar Gum: Hoʻohana ʻia i nā huahana meaʻai (e laʻa, nā meaʻai i hoʻomoʻa ʻia, ka waiu, nā mea inu), nā lāʻau lapaʻau (e laʻa, nā papa, nā hoʻokuʻu ʻia), nā mea hoʻonaninani (e laʻa, nā kilika, nā lotions), paʻi lole, a me nā wai hoʻoheheʻe hydraulic i ka ʻoihana ʻaila.

Ka hopena:

ʻOiai ka sodium carboxymethyl cellulose (CMC), xanthan gum, a me ka guar gum kaʻana like i kā lākou mau hana a me nā noi e like me hydrocolloids, hōʻike pū lākou i nā ʻokoʻa like ʻole i kā lākou mau hana kemika, nā kumu, nā waiwai, a me nā hoʻohana.He mea nui ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no ke koho ʻana i ka hydrocolloid kūpono loa no nā noi kikoʻī ma nā ʻoihana like ʻole.Hāʻawi kēlā me kēia hydrocolloid i nā pono kūʻokoʻa a me nā hiʻohiʻona hana i hiki ke hoʻohālikelike ʻia e hoʻokō i nā koi o nā ʻano hana like ʻole a me nā kaʻina hana.
