ʻO Xanthan gum a me Hydroxyethyl cellulose (HEC) nā hydrocolloids i hoʻohana nui ʻia i nā ʻoihana like ʻole, ʻoi loa i ka meaʻai, nā lāʻau lapaʻau, a me nā huahana mālama pilikino. ʻOiai kekahi mau mea like i kā lākou noi, ʻokoʻa lākou ma ke ʻano o kā lākou ʻano kemika, nā waiwai, a me nā hana.
1. Kemimi Hana:
Xanthan gum: He polysaccharide i loaʻa mai i ka fermentation o nā carbohydrates, ʻo ka glucose mua, e ka huakini Xanthomonas campestris. Loaʻa iā ia kahi iwi kuamoʻo o nā koena glucose me nā kaulahao ʻaoʻao o nā trisaccharide repeat units, me ka mannose, glucuronic acid, a me ka glucose.
HEC: ʻO ka hydroxyethyl cellulose he etera cellulose non-ionic i loaʻa mai ka cellulose, he polysaccharide kūlohelohe i loaʻa i loko o nā paia o nā mea kanu. Hoʻololi ʻia ka HEC ma ka hoʻokomo ʻana i nā pūʻulu hydroxyethyl ma ka iwi kuamoʻo cellulose.
2.Solubility:
Xanthan gum: Hōʻike ia i ka solubility kiʻekiʻe i ka wai anuanu a me ka wai wela. Hoʻokumu ia i nā hāʻina viscous loa ma nā haʻahaʻa haʻahaʻa.
HEC: Hiki ke hoʻoheheʻe ʻia ka hydroxyethyl cellulose i ka wai, a hiki ke hoʻololi ʻia kona hoʻoheheʻe ʻia ma muli o ke ʻano o ka hoʻololi ʻana (DS) o nā hui hydroxyethyl. ʻO ka DS kiʻekiʻe ka hopena maʻamau i ka solubility maikaʻi.
3. Viscosity:
Xanthan gum: Ua ʻike ʻia no kāna mau waiwai mānoanoa. ʻOiai ma nā haʻahaʻa haʻahaʻa, hiki i ka xanthan gum ke hoʻonui nui i ka viscosity o nā hopena.
HEC: ʻO ka viscosity o nā haʻina HEC e pili pū ana i nā mea e like me ka noʻonoʻo, ka mahana, a me ka nui o ka shear. ʻO ka maʻamau, hōʻike ʻo HEC i nā waiwai mānoanoa maikaʻi, akā ʻoi aku ka haʻahaʻa o kona viscosity i hoʻohālikelike ʻia me ka xanthan gum ma nā ʻano like.
4. ʻAhi ʻāhiʻi ʻana:
Xanthan gum: Hōʻike maʻamau nā ʻoluʻolu o ka xanthan gum i ke ʻano shear-thinning, ʻo ia hoʻi, e emi ana ko lākou viscosity ma lalo o ke koʻikoʻi shear a hoʻi hou ke hoʻopau ʻia ke kaumaha.
HEC: Pēlā nō, hōʻike pū ʻia nā hoʻonā HEC i ka hana ʻāhiʻi, ʻoiai ʻokoʻa ka nui ma muli o ke kūlana kikoʻī a me nā kūlana hoʻonā.
5. Hoʻohālikelike:
Xanthan gum: He kūpono ia me ka nui o nā hydrocolloids ʻē aʻe a me nā mea hoʻohana maʻamau i nā meaʻai a me nā hoʻoponopono pilikino. Hiki iā ia ke hoʻopaʻa i nā emulsions.
HEC: He kūpono pū ka Hydroxyethyl cellulose me nā mea like ʻole a hiki ke hoʻohana pū ʻia me nā mea mānoanoa a me nā stabilizers e hoʻokō ai i nā waiwai rheological i makemake ʻia.
6.Synergy me nā mea mānoanoa ʻē aʻe:
Xanthan gum: Hōʻike ia i nā hopena synergistic ke hui pū ʻia me nā hydrocolloids ʻē aʻe e like me ka guar gum a i ʻole ʻūhini ʻūhini gum, e hoʻonui ai i ka viscosity a me ka paʻa.
HEC: Pēlā nō, hiki iā HEC ke hui pū me nā mānoanoa a me nā polymers ʻē aʻe, e hāʻawi ana i ka versatility i ka hoʻokumu ʻana i nā huahana me nā kikoʻī kikoʻī a me nā koi hana.
7. Nā ʻāpana noi:
Xanthan gum: Loaʻa iā ia ka hoʻohana nui ʻana i nā huahana meaʻai (e laʻa, nā meaʻai, nā lole, nā huahana waiu), nā huahana mālama pilikino (e laʻa, nā lotions, nā ʻaila, nā niho niho), a me nā huahana ʻoihana (e laʻa, nā wai wili, pena).
HEC: Hoʻohana maʻamau ʻia ka Hydroxyethyl cellulose i nā huahana mālama pilikino (e laʻa, shampoos, holoi kino, holika), lāʻau lapaʻau (e laʻa, nā hoʻonā ophthalmic, hoʻokuʻu waha), a me nā mea hana (e laʻa, pena, nā mea hoʻopili).
8. Ke kumu kūʻai a me ka loaʻa:
Xanthan gum: ʻOi aku ka nui o ke kumukūʻai ma mua o HEC, ma muli o ke kaʻina hana fermentation i loko o kāna hana. Eia nō naʻe, ʻo kāna hoʻohana ākea a me ka loaʻa ʻana e kōkua i kāna lako mākeke paʻa.
HEC: ʻOi aku ka maikaʻi o ka hydroxyethyl cellulose ma mua o ka xanthan gum. Hoʻopuka nui ʻia ia ma o ka hoʻololi kemika o ka cellulose, he nui ke ʻano.
ʻoiai ka xanthan gum a me HEC i kekahi mau mea like i kā lākou noi e like me ka hydrocolloids, hōʻike lākou i nā ʻokoʻa like ʻole ma ke ʻano o kā lākou hana kemika, solubility, viscosity, shear-thinning behavior, compatibility, synergy with other thickeners, application areas, and cost. ʻO ka hoʻomaopopo ʻana i kēia mau ʻokoʻa he mea koʻikoʻi ia no nā mea hoʻokumu e koho i ka hydrocolloid kūpono loa no nā hoʻokumu huahana kikoʻī a me nā ʻano hana i makemake ʻia.
