Mechanism Hana o ka Stabilization o Acidified Waiu Inu e CMC

Ua kaulana nui nā mea inu waiu waiʻona i nā makahiki i hala iho nei ma muli o ko lākou mau pono olakino a me ka ʻono kū hoʻokahi. Eia nō naʻe, hiki i kēia mau mea inu ke paʻakikī i ka hoʻopaʻa ʻana, no ka mea, hiki i ka waika i ka waiū ke hoʻoneʻe i nā protein a hana i nā aggregates, e alakaʻi ana i ka sedimentation a me ka hoʻokaʻawale ʻana. ʻO kahi ala maikaʻi o ka hoʻopaʻa ʻana i nā mea inu waiu acidified ma o ka hoʻohana ʻana i ka carboxymethyl cellulose (CMC), he polymer hiki ke hoʻoheheʻe wai i hiki ke launa pū me nā protein a me nā mea ʻē aʻe e hana ai i nā hoʻokuʻu paʻa. Ma kēia ʻatikala, e kūkākūkā mākou i ke ʻano hana o ka hoʻopaʻa ʻana i nā mea inu waiu acidified e CMC.

Hoʻolālā a me nā waiwai o CMC

ʻO ka CMC he mea ia o ka cellulose, he polymer maoli i loaʻa i loko o nā paia o nā mea kanu. Hana ʻia ia ma ke kemika hoʻololi ʻana i ka cellulose me nā hui carboxymethyl, e hoʻomaikaʻi ai i kona ʻano wai a me nā waiwai ʻē aʻe. ʻO ka CMC he polimer lālā nui me ka iwi kuamoʻo laina laina lōʻihi a me nā kaulahao ʻaoʻao he nui o nā hui carboxymethyl. ʻO ka degere o ka hoʻololi ʻana (DS) o CMC e pili ana i ka helu o nā hui carboxymethyl i kēlā me kēia pūʻulu cellulose, a hoʻoholo ia i ka degere o ka solubility a me ka viscosity o CMC.

Mechanism Hana a CMC i ka hoʻopaʻa ʻana i nā mea inu waiu waiʻona

ʻO ka hoʻohui ʻana o CMC i nā mea inu waiu acidified hiki ke hoʻomaikaʻi i ko lākou kūpaʻa ma o kekahi mau hana:

  1. Electrostatic Repulsion: Hoʻopiʻi maikaʻi ʻia nā hui carboxymethyl ma CMC a hiki ke launa pū me nā protein i hoʻopiʻi maikaʻi ʻia a me nā mea ʻē aʻe i loko o ka waiū, e hana ana i kahi mana repulsive e pale ai i nā protein mai ka hōʻuluʻulu ʻana a me ka hoʻonohonoho ʻana. Hoʻopaʻa kēia electrostatic repulsion i ka hoʻokuʻu ʻana a pale i ka sedimentation.
  2. Nā Pākuʻi Hydrophilic: ʻO ke ʻano hydrophilic o CMC hiki iā ia ke launa pū me nā molekele wai a me nā mea hydrophilic ʻē aʻe i loko o ka waiū, e hana i kahi papa pale a puni nā protein a pale iā lākou mai ka launa pū ʻana me kekahi.
  3. Steric Keʻakeʻa: Ka lālā lālā oCMCHiki iā ia ke hana i kahi hopena steric hindrance, pale i nā protein mai ka hoʻopili kokoke ʻana a hoʻokumu i nā aggregates. Hiki i nā kaulahao lōʻihi a maʻalahi o CMC ke kāʻei a puni i nā ʻāpana protein, e hana ana i kahi pale e pale ai iā lākou mai ka launa pū ʻana me kekahi.
  4. Viscosity: ʻO ka hoʻohui ʻana o CMC i nā mea inu waiu acidified hiki ke hoʻonui i ko lākou viscosity, hiki ke pale i ka sedimentation ma ka hoʻemi ʻana i ka wikiwiki o ka hoʻonohonoho ʻana o nā ʻāpana. Hiki i ka hoʻonui viscosity ke hana i kahi hoʻokuʻu paʻa ma o ka hoʻonui ʻana i ka pilina ma waena o ka CMC a me nā mea ʻē aʻe o ka waiū.

Nā mea e pili ana i ka hoʻopaʻa ʻana o nā mea inu waiu waiu e CMC

ʻO ka maikaʻi o CMC i ka hoʻopaʻa ʻana i nā mea inu waiu acidified e pili ana i nā kumu he nui, e like me:

  1. pH: ʻO ke kūpaʻa o nā mea inu waiu wai i hoʻopaʻa ʻia e ka pH. Ma nā koina pH haʻahaʻa, e hoʻopaʻa ʻia nā protein i loko o ka waiū a maʻalahi ka hoʻohui ʻana, e ʻoi aku ka paʻakikī o ka hoʻopaʻa ʻana. Hiki i ka CMC ke hoʻopaʻa i nā mea inu waiu ʻakika ma nā kumu pH haʻahaʻa e like me 3.5, akā e emi ana kona pono ma nā kumu pH haʻahaʻa.
  2. Hoʻopili ʻia o CMC: ʻO ka neʻe ʻana o ka CMC i loko o ka waiū e pili ana i kāna mau waiwai paʻa. Hiki ke hoʻonui i ka viscosity a me ka hoʻopaʻa ʻana i nā kiʻekiʻe kiʻekiʻe o ka CMC, akā hiki i ke kiʻekiʻe kiʻekiʻe ke hopena i ke ʻano a me ka ʻono maikaʻi ʻole.
  3. ʻO ka hoʻopaʻa ʻana o ka Protein: ʻO ke ʻano a me ke ʻano o nā protein i loko o ka waiū hiki ke hoʻopilikia i ka paʻa o ka inu. ʻOi aku ka maikaʻi o ka CMC i ka hoʻopaʻa ʻana i nā mea inu me ka haʻahaʻa haʻahaʻa o ka protein, akā hiki iā ia ke hoʻopaʻa i nā mea inu me ka kiʻekiʻe o ka protein inā liʻiliʻi a puʻunaue like ʻia nā ʻāpana protein.
  4. Nā Kūlana Kaʻina Hana: ʻO nā kūlana hana i hoʻohana ʻia no ka hana ʻana i ka inu waiu waiʻa hiki ke hoʻopilikia i kona kūpaʻa. Hiki i nā ikaika shear kiʻekiʻe a me ka wela ke kumu i ka denaturation a me ka hōʻuluʻulu ʻana o ka protein, e alakaʻi ana i ka paʻa ʻole. Pono e hoʻopaneʻe ʻia nā kūlana hana e hōʻemi i ka protein.

Ka hopena

I ka hopena, ʻo ka hoʻopaʻa ʻana o nā mea inu waiu acidified e CMC he kaʻina hana paʻakikī e pili ana i nā ʻano hana like ʻole, me ka electrostatic repulsion, hydrophilic interactions, steric hindrance, a me ka viscosity. Hana pū kēia mau mea hana i mea e pale ai i ka hōʻuluʻulu ʻana o ka protein a me ka hoʻoheheʻe ʻana, ka hopena i ka hoʻokuʻu paʻa ʻana a me ke ʻano like. ʻO ka maikaʻi o ka CMC i ka hoʻopaʻa ʻana i nā mea inu waiu acidified e pili ana i nā kumu he nui, me ka pH, ka ʻike CMC, ka ʻike protein, a me nā kūlana hana. Ma ka hoʻomaopopo ʻana i ke ʻano hana o ka CMC i ka hoʻopaʻa ʻana i nā mea inu waiu acidified, hiki i nā mea hana ke hoʻopaʻa pono i kā lākou hana ʻana e hoʻokō i ke kūpaʻa a me ke ʻano i makemake ʻia me ka mālama ʻana i ka ʻono a me nā pono olakino o ka inu.
