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.
• Hana ʻia ka Xanthan gum ma o ka microbial fermentation o nā ʻakika 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 nā hoʻonā Xanthan gum ma luna o kahi ākea pH ākea a kūpaʻa i ka wela, shear, a me nā electrolytes.
• Hiki ke hōʻike ʻia nā haʻina Guar gum i ke kūpaʻa haʻahaʻa ma ka pH haʻahaʻa a i ʻole i mua 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 salakeke, nā ʻuala, ka waiū), nā lāʻau lapaʻau (e laʻa, ka hoʻokuʻu ʻana, mālama waha), nā mea hoʻonaninani (e laʻa, nā kilika, toothpaste), nā 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.
