He aha ka ʻokoʻa ma waena o ka xanthan gum a me HEC?

ʻO Xanthan gum a me Hydroxyethyl cellulose (HEC) he mau hydrocolloids i hoʻohana nui ʻia i nā ʻoihana like ʻole, me ka meaʻai, nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā huahana mālama pilikino. ʻOiai ke kaʻana like ʻana i kā lākou mau waiwai a me nā noi, aia nā ʻokoʻa like ʻole ma waena o nā mea ʻelua.

Hoʻohui a me ke ʻano:

Xanthan Gum:
Xanthan gumhe polysaccharide i loaʻa mai i ka fermentation o nā carbohydrates e ka huakini Xanthomonas campestris. Loaʻa iā ia nā ʻāpana glucose, mannose, a me glucuronic acid, i hoʻonohonoho ʻia i loko o kahi ʻano lālā nui. Aia ka iwi kuamoʻo o ka xanthan gum i nā ʻāpana hou o ka glucose a me ka mannose, me nā kaulahao ʻaoʻao o ka glucuronic acid a me nā pūʻulu acetyl.

HEC (Hydroxyethyl Cellulose):
HEChe kumu ia o ka cellulose, he polymer maoli i loaʻa i loko o nā paia o nā mea kanu. I ka hana ʻana o HEC, hoʻopili ʻia ka ethylene oxide me ka cellulose e hoʻokomo i nā pūʻulu hydroxyethyl ma ka iwi kuamoʻo cellulose. Hoʻonui kēia hoʻololi i ka hoʻoheheʻe wai a me nā waiwai rheological o cellulose.

Nā waiwai:

Xanthan Gum:
Viscosity: Hāʻawi ʻo Xanthan gum i ka viscosity kiʻekiʻe i nā hoʻonā wai a hiki i nā haʻahaʻa haʻahaʻa, e lilo ia i mea mānoanoa kūpono.
ʻO ke ʻano hoʻoheheʻe shear: Hōʻike nā ʻano hoʻonā i loaʻa i ka xanthan gum ke ʻano hoʻoheheʻe ʻia, ʻo ia hoʻi, e emi ana lākou ma lalo o ke koʻikoʻi shear a hoʻihoʻi i ko lākou viscosity ke wehe ʻia ke koʻikoʻi.
Paʻa: Hāʻawi ka Xanthan gum i ke kūpaʻa i nā emulsions a me nā hoʻokuʻu, e pale ana i ka hoʻokaʻawale ʻana.
Hoʻohālikelike: He kūpono ia me kahi ākea o nā pae pH a hiki ke kū i nā wela kiʻekiʻe me ka ʻole o ka nalowale ʻana o kāna mau waiwai mānoanoa.

HEC:
Viscosity: He hana mānoanoa hoʻi ʻo HEC a hōʻike i ka viscosity kiʻekiʻe i nā hoʻonā wai.
Non-ionic: ʻAʻole like me ka xanthan gum, HEC he non-ionic, kahi e emi ai ka naʻau i nā loli i ka pH a me ka ikaika ionic.
Hana kiʻiʻoniʻoni: Hoʻokumu ʻo HEC i nā kiʻiʻoniʻoni alohilohi i ka wā e maloʻo ai, e hoʻohana pono ai i nā noi e like me nā uhi a me nā mea hoʻopili.
ʻO ka ʻae ʻana i ka paʻakai: mālama ʻo HEC i kona viscosity i mua o nā paʻakai, hiki ke hoʻomaikaʻi i kekahi mau ʻano.

Hoʻohana:

Xanthan Gum:
ʻOihana Meaʻai: Hoʻohana mau ʻia ka Xanthan gum ma ke ʻano he stabilizer, mānoanoa, a me ka gelling agent i nā ʻano meaʻai like ʻole, e like me nā meaʻai, nā lole, nā mea bakena, a me nā huahana waiū.
Mea hoʻomaʻamaʻa: Hoʻohana ʻia ia i loko o nā mea hoʻonaninani e like me ka ʻaila, nā lotions, a me ka niho niho e hāʻawi i ka viscosity a me ka paʻa.
Aila a me Gas: Hoʻohana ʻia ʻo Xanthan gum i ka ʻeli ʻana i nā wai i loko o ka ʻoihana aila a me ke kinoea e hoʻomalu i ka viscosity a hoʻokuʻu i nā mea paʻa.

HEC:
Nā Pena a me nā Kāpena: Hoʻohana nui ʻia ʻo HEC i nā pena wai, nā uhi, a me nā mea hoʻopili e kāohi i ka viscosity, hoʻomaikaʻi i nā waiwai kahe, a hoʻomaikaʻi i ka hoʻokumu ʻana i ke kiʻiʻoniʻoni.
Nā huahana mālama pilikino: He mea maʻamau ia i nā huahana mālama pilikino e like me nā shampoos, conditioners, a me nā ʻaila ma muli o kona mānoanoa a me ka hoʻopaʻa ʻana i nā waiwai.
ʻO nā lāʻau lapaʻau: Hoʻohana ʻia ʻo HEC ma ke ʻano he mea hoʻopaʻa i nā papa papa a ma ke ʻano he mānoanoa i nā lāʻau lapaʻau wai.

Nā ʻokoʻa:
Kumu: Hana ʻia ka Xanthan gum e ka fermentation bacteria, aʻo HEC i loaʻa mai ka cellulose ma o ka hoʻololi kemika.
ʻAno Ionic: He anionic ka Xanthan gum, ʻoiai ʻo HEC he non-ionic.
Paʻakai Paʻakai: Xanthan gum ka mea maʻalahi i ka paʻakai kiʻekiʻe, akā mālama ʻo HEC i kona viscosity i mua o nā paʻakai.
Hoʻokumu kiʻiʻoniʻoni: Hoʻokumu ʻo HEC i nā kiʻiʻoniʻoni alohilohi i ka wā e maloʻo ai, hiki ke hoʻomaikaʻi i ka uhi ʻana, ʻoiai ʻaʻole hōʻike ka xanthan gum i kēia waiwai.

ʻO ke ʻano Viscosity: ʻOiai ʻo xanthan gum a me HEC e hāʻawi i ka viscosity kiʻekiʻe, hōʻike lākou i nā ʻano rheological like ʻole. Hōʻike ka hoʻonā ʻana o Xanthan gum i ke ʻano shear-thinning, akā ʻo ka HEC solutions e hōʻike maʻamau i ke ʻano Newtonian a i ʻole ka shear-thinning haʻahaʻa.
Hoʻohana: ʻOiai aia kekahi ʻāpana i kā lākou noi, hoʻohana pinepine ʻia ka xanthan gum i ka ʻoihana meaʻai a ma ke ʻano he mea hoʻohui wai wili, ʻoiai ʻo HEC e ʻike nui i ka hoʻohana ʻana i nā pena, nā uhi, a me nā huahana mālama pilikino.

oiai ka xanthan gum a me HEC i kekahi mau mea like e like me ka hydrocolloids i hoʻohana ʻia no ka mānoanoa a me ka hoʻopaʻa ʻana i nā ʻōnaehana wai, ʻokoʻa lākou i ko lākou kumu, ʻano ionic, ʻike paʻakai, nā waiwai hana kiʻiʻoniʻoni, a me nā noi. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no ke koho ʻana i ka hydrocolloid kūpono no nā hana kikoʻī a me nā waiwai i makemake ʻia.
