ʻO nā Emulsifiers vs Solubilizers: He aha nā ʻokoʻa?

ʻO ke kāwili ʻana i nā mea hiki ʻole ke hoʻohuihui ʻia e hana i nā hopena kemika akamai! Inā ua hoʻāʻo ʻoe e kāwili iā lākou, ʻike ʻoe ʻaʻole hui maʻalahi ka ʻaila a me ka wai. Eia nō naʻe, me ke kōkua o nā emulsifiers a me nā solubilizers, hiki ke hoʻokō ʻia kēia hana hiki ʻole ke hana ʻia.—akā, he ʻelua pi anei lāua i loko o kahi ʻōpuʻu? Kokoke! He kuleana kū hoʻokahi ko kēlā me kēia. E kāʻei i ke kāʻei, e ka poʻe hoihoi i ka ʻepekema, a e mākaukau e ʻimi i nā ʻokoʻa ma waena o nā emulsifiers a me nā solubilizers.

He aha kaMea hoʻohuihui?

Hana nā Emulsifiers ma ke ʻano he mea hoʻohālikelike i loko o ke ao molekala, e hoʻopaʻa pono ana i nā molekala aila a me nā molekala wai e makemake mau ana e noho kaʻawale. Hana lākou ma ka hoʻohaʻahaʻa ʻana i ke kaomi ʻili ma waena o nā wai, e hana ana i kahi hui paʻa i ʻike ʻia he emulsion. Ma ka pae molekala, amphipathic nā emulsifiers.—Loaʻa iā lākou kekahi hopena hydrophilic (aloha wai) a me kekahi hopena hydrophobic (aloha ʻaila).

ʻO kēia duality e hiki ai iā lākou ke hoʻopaʻa iā lākou iho ma waena o ka aila a me ka wai, e hana ana i kahi pale pale a puni nā kulu wai a pale i ka hoʻokaʻawale ʻana. ʻO nā emulsifiers maʻamau āu e kamaʻāina ai me ka lecithin i loaʻa i loko o nā yolks hua manu, a me ka lecithin soy a i ʻole ka sunflower kaulana i hoʻohana nui ʻia i loko o ke kokoleka a me nā mea i hoʻomoʻa ʻia e hoʻokō ai i kahi ʻano laumania maikaʻi.

He aha kaMea hoʻoheheʻe?

ʻOiai ua kuhihewa pinepine ʻia he mau emulsifiers, hana nā solubilizers i kahi hana ʻokoʻa loa i ka hula o ka hoʻoheheʻe ʻana. He akamai kēia mau mea hana i ka ulana ʻana i ka ʻaila paʻakikī a me ka wai e hana i kahi hopena maopopo me ka ʻike ʻole ʻia o ka hoʻokaʻawale ʻana, ʻoiai i ka maka ʻoi loa. ʻO ke kumu, hana nā solubilizers i ka ʻaila e like me ka nalowale loa i loko o ka wai.

Hoʻokō lākou i kēia ma ka hoʻopuni ʻana i nā ʻāpana aila me kahi pūpū waho hydrophilic, e hūnā ana iā lākou i loko o kahi papa wai i hiki iā lākou ke hoʻoheheʻe me ka ʻole o kahi kaha. Hoʻopuka kēia kaʻina hana i kahi hopena ma mua o kahi emulsion. Hiki ke loaʻa nā mea hoʻoheheʻe i loko o nā huahana like ʻole, mai nā mea hoʻomaʻemaʻe maka e wehe i ka makeup aila a hiki i nā mea hoʻolaha aila koʻikoʻi e hoʻokuʻu i ka ʻala me ka waiho ʻole ʻana i nā koena; ʻo nā laʻana e komo pū me nā polysorbates, nā alcohols a me nā hui ethoxylated.

He aha nā ʻokoʻa ma waena o lākou?

ʻO ke ʻokoʻa nui ma waena o nā emulsifiers a me nā solubilizers aia i ka hopena hope o kā lākou hana. Kōkua nā emulsifiers i ka hana ʻana i nā ʻano hou a me nā kūlike, e like me ka hōʻike ʻana e nā emulsions paʻa i hana ʻia i ka wā e kau ʻia ai nā kulu aila ma loko o kahi kumu wai. ʻO ka hopena he huahana e ʻike ʻia he ao, a hana ʻia kēia no ka mea ua piha i nā kulu aila liʻiliʻi i kau like ʻia i loko o ka wai a puni.

I ka hoʻohālikelike ʻana, hoʻopau loa nā mea hoʻoheheʻe i ka ʻaila i loko o ka wai, e lawelawe ana i kahi hana koʻikoʻi i nā huahana kahi i koʻikoʻi ai ka moakāka. Hoʻokomo malū lākou i ka ʻaila i loko o ka wai, e loaʻa ai nā hopena moakaka.
