He aha ka carrageenan?
He aha ka carrageenan? Ua lilo kēia nīnau i mea maʻamau i nā makahiki i hala iho nei i kekahi mau ʻoihana, me ka meaʻai, nā lāʻau lapaʻau a me nā mea hoʻonaninani. ʻO Carrageenan kahi polysaccharide kūlohelohe i loaʻa mai nā limu ʻulaʻula (ʻoi aku ka limu) a hoʻohana nui ʻia no kāna mau waiwai colloidal maikaʻi loa. Ma kēia ʻatikala, e hāʻawi mākou iā ʻoe i kahi loiloi hohonu o nā waiwai kikoʻī a me nā hopena o ka carrageenan e pili ana i nā kumu, nā ʻano, nā noi a me nā hopena olakino.
Nā kumu a me ka unuhi ʻana o Carrageenan
Loaʻa ka Carrageenan mai nā limu ʻulaʻula, ʻoi aku ka nui o nā ʻano kai Eucheuma cottonii a me Kappaphycus alvarezii. Ma ka hoʻomaloʻo ʻana, ka holoi ʻana a me ka mālama ʻana i ka alkali o kēia mau limu, ua unuhi ʻia nā polysaccharides wai-soluble i kapa ʻia ʻo carrageenan. ʻO ke kaʻina hana hoʻoheheʻe he mea kūlohelohe, pili kaiapuni a ʻaʻole pili i nā mea hoʻoheheʻe kemika, e lilo ia i kumu waiwai biodegradable a hoʻomau.
Nā ʻano carrageenan
Hoʻokaʻawale ʻia ʻo Carrageenan i ʻekolu mau ʻano nui e pili ana i nā ʻano molekala like ʻole a me nā waiwai gel: ʻano ʻano (kappa), ʻano ι (eta) a ʻano ʻano λ (lambda).

κ-type carrageenan: loaʻa ka ikaika gel kiʻekiʻe a hiki ke hana i nā gel paʻakikī i mua o nā ion potassium. Hoʻohana nui ʻia i ka ʻiʻo a me nā huahana waiū.
ʻAno ι carrageenan: palupalu a elastic, hoʻohana pinepine ʻia e hoʻonui i ka paʻa a me ka paʻa o nā huahana, i loaʻa mau i nā mea ʻono a me nā huahana waiu.
λ Carrageenan: hiki ʻole ke hana i nā gels, hoʻohana nui ʻia ma ke ʻano he mānoanoa, kūpono no nā huahana wai e like me nā mea inu a me nā ʻuala.

Loaʻa nā ʻano carrageenan i kā lākou mau hiʻohiʻona noiʻi kūikawā, no laila he mea koʻikoʻi ke koho i ke ʻano kūpono e like me nā pono kikoʻī.
Nui o nā noi carrageenan
He aha ka carrageenan a no ke aha i hoʻohana nui ʻia ai? Aia nā ikaika nui o Carrageenan i kāna mau waiwai hana o ka mānoanoa, gelling, stabilizing a emulsifying. Eia kekahi mau wahi noi nui:

ʻOihana meaʻai: ʻO Carrageenan kahi mea hoʻohui meaʻai maʻamau i hoʻohana nui ʻia i nā huahana waiu (e laʻa i ka ice cream, yogurt, waiu kokoleka), nā huahana ʻiʻo (e laʻa i ka sausage, ham) a me nā meaʻai i kālua ʻia. ʻAʻole ia e mānoanoa a hoʻopaʻa i ka meaʻai, akā hoʻomaikaʻi pū i ka ʻono a hoʻonui i ke ola o ka papa.
ʻOihana lāʻau lapaʻau: ʻO ka biocompatibility o Carrageenan he mea kūpono ia no ka hoʻohana ʻana ma ke ʻano he uhi capsule a me ka mea hoʻopaʻa papa i nā hoʻomākaukau lāʻau.
Mea hoʻomaʻemaʻe a me ka mālama pilikino: ʻO Carrageenan ka moisturizing a me ka hoʻopaʻa ʻana i nā waiwai i lilo ia i mea maʻamau i nā mea hoʻonaninani e like me nā lotions, shampoos a me nā ʻaila.

Nā hopena olakino o ka carrageenan
ʻO ka palekana o ka carrageenan i hāpai i kekahi mau hopohopo i nā makahiki i hala iho nei. Ua hāpai ʻia nā nīnau e pili ana i ka ʻeli ʻana o ka carrageenan a inā paha he hopena ʻino ia ma ka ʻōpū ʻōpū. Eia nō naʻe, ua hōʻike ʻia i loko o kekahi mau noiʻi ʻana he palekana ka carrageenan meaʻai i nā pae hoʻohana maʻamau a ʻaʻole ia e hoʻopilikia i ke olakino. He mea nui e hōʻoia nā mea kūʻai aku e koho ana lākou i ka carrageenan meaʻai kiʻekiʻe ma mua o ka mālama ʻole ʻia a i ʻole nā ​​​​mea haʻahaʻa haʻahaʻa.
Hōʻuluʻulu manaʻo
He aha ka carrageenan? He polysaccharide kūlohelohe ia i loaʻa mai ka limu i loaʻa nā ʻano ʻano like ʻole me ka mānoanoa, gelling a me ka hoʻomau. Hoʻohana nui ʻia i ka ʻoihana meaʻai, lāʻau lapaʻau a me nā ʻoihana hoʻonaninani, hana nui ka carrageenan i ka ʻoihana hou. ʻOiai aia kekahi mau hoʻopaʻapaʻa e pili ana i kona palekana, ʻo ka nui o nā hōʻike ʻepekema e hōʻike ana i ka hoʻohana pono ʻana o ka carrageenan ʻaʻohe pilikia nui i ke olakino kanaka. No laila, e hoʻomau ka carrageenan i kāna hana hiki ʻole ke hoʻololi ʻia ma nā kahua nui a pau i ka wā e hiki mai ana.
Ma o ka ʻike kikoʻī o kēia ʻatikala, pono ʻoe e ʻike maopopo i ka "he aha ka carrageenan" i kēia pilikia. ʻAʻole ʻo Carrageenan wale nō kahi kumu waiwai kūlohelohe a hoʻomau, ʻo kāna mau noi like ʻole e lilo ia i mea waiwai nui i ka ʻoihana hou.
