He hana kemika akamai ka hoʻohuihui ʻana i nā mea hiki ʻole ke hoʻohuihui ʻia! Inā ua hoʻāʻo ʻoe e hoʻohuihui iā lākou, e 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 hana ʻia kēia hana hiki ʻole.—akā, ʻaʻole anei he ʻelua wale nō pī i loko o kahi ʻōpuʻu i loko o ka bead? ʻAʻole loa! 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 ka emulsifier?
ʻO nā emulsifiers nā mea hoʻohālikelike o ka honua molekala, e lawe akamai ana i nā molekala aila a me nā molekala wai e hele pinepine ana i ko lākou mau ala kaʻawale. ʻO kā lākou kumu hana ka hoʻemi ʻana i ka haunaele o ka ʻili ma waena o nā wai, e hana ana i kahi hui paʻa i kapa ʻia he emulsion. Ma ka pae molekala, amphiphilic nā emulsifiers.—Loaʻa iā lākou kekahi hopena hydrophilic (aloha wai) a me kekahi hopena hydrophobic (aloha ʻaila). ʻAe kēia duality iā lākou e hoʻokomo iā lākou iho ma waena o ka ʻaila a me ka wai, e hana ana i kahi pale pale a puni nā kulu e pale aku ai iā lākou mai ka hoʻokaʻawale ʻana. ʻO nā emulsifiers maʻamau āu e kamaʻāina ai me ka lecithin i loko o nā yolks hua manu, a me ka lecithin soy a i ʻole ka sunflower kaulana i hoʻohana nui ʻia i ke kokoleka a me nā mea i hoʻomoʻa ʻia e hoʻokō i kahi ʻano laumania maikaʻi.
He aha ka mea hoʻoheheʻe?
ʻOiai ua kuhihewa pinepine ʻia nā mea hoʻoheheʻe me nā emulsifiers, he ʻokoʻa loa kā lākou hana i ka hula o ka hoʻoheheʻe ʻana. He akamai kēia mau mea hana i ka ulana ʻana i nā aila paʻakikī a me ka wai e hana i kahi hopena moakaka, kahi hiki ʻole i ka maka ʻoi loa ke ʻike i ka hoʻokaʻawale ʻana. ʻO ke kumu, hana nā mea hoʻoheheʻe i nā aila me he mea lā ua nalowale loa i loko o ka wai. Hoʻokō lākou i kēia ma ka hoʻopuni ʻana i nā ʻāpana aila me kahi pūpū hydrophilic, e hūnā ana iā lākou i loko o kahi ʻaʻahu wai, e ʻae ana iā lākou e hoʻoheheʻe me ka ʻole o kahi kaha. Hoʻopuka kēia kaʻina hana i kahi hopena ma mua o ka emulsion. Hiki iā ʻoe ke loaʻa nā mea hoʻoheheʻe i nā huahana like ʻole, mai nā mea hoʻomaʻemaʻe maka e holoi i nā mea hoʻonani aila a hiki i nā mea hoʻolaha aila koʻikoʻi e hoʻopuka i ka ʻala me ka waiho ʻole ʻana i nā koena, e like me polysorbates, alcohols, a me nā hui ethoxylated.
He aha ka ʻokoʻa ma waena o lākou?
ʻO ka ʻokoʻa nui ma waena o nā emulsifiers a me nā solubilizers aia i kā lākou hopena 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 like me ke ao, akā ʻo kēia no ka mea ua piha i nā momi aila liʻiliʻi e hoʻopiha i ka wai a puni. I ka hoʻohālikelike ʻana, hoʻolilo nā solubilizers i ka aila e nalowale loa i loko o ka wai, e pāʻani ana i kahi kuleana koʻikoʻi i nā huahana kahi i mea nui ai ka transparency. Hoʻokomo malū lākou i ka aila i loko o ka wai, e hopena ana i kahi hopena aniani.
