Pehea ka lōʻihi o ka hana ʻana o DHA?

 

He aha DHA alga?

ʻO DHA, docosahexaenoic acid, i kapa ʻia ʻo ka lolo gula, he polyunsaturated fatty acid i mea nui loa i ke kino o ke kanaka a he lālā koʻikoʻi ia o ka ʻohana Omega-3 unsaturated fatty acid. He mea nui ka DHA no ka ulu ʻana a me ka mālama ʻana i nā pūnaewele pūnaewele. He ʻakika momona nui ia o ka lolo a me ka retina. ʻO ka maʻiʻo o DHA i loko o ka cerebral cortex kanaka he kiʻekiʻe e like me 20%, a ʻo ia ka hapa nui loa o ka retina o ka maka, ʻo ia ka 50%. He mea nui ia no ka ulu ʻana o ka naʻauao a me ka ʻike o nā pēpē. Lawe ʻia ka ʻaila algae DHA mai loko mai o ka microalgae moana a he relaʻoi aku ka palekana me ka hāʻawi ʻole ʻia e ke kaulahao meaʻai. He haʻahaʻa loa kona ʻike EPA.

 

I ka makahiki 2010, ua ʻōlelo maopopo ʻia ka "National Food Safety Standard Infant Formula Food" inā e hoʻohui ʻia ka waika docosahexaenoic (22:6n-3) i ke ʻano pēpē, pono e hoʻohui ʻia ka nui like o ka eicosatetraene Acid (20:4n-6) . ʻAʻole pono ka nui o ka waikawa eicosapentaenoic (20: 5n-3) i loko o ke kaulahao lōʻihi unsaturated fatty acid ma mua o ka nui o ka docosahexaenoic acid. ʻO ia hoʻi, inā hoʻohui ʻia ka DHA i ka ʻai keiki, pono e hoʻohui ʻia ka nui like o ka ARA. A ʻaʻole hiki ke ʻoi aku ka nui o ka EPA ma mua o ka nui o DHA.

 

Ua like anei ka DHA me ka aila i'a?

waiu waiu

ʻO ka DHA i hoʻohui ʻia i loko o ka pauka waiu waiu, ʻo ia ka ʻano ʻaila iʻa a me ke ʻano ʻaila algae. Hiki i ka ʻaila iʻa DHA ke loaʻa i ka haumia. No laila, ʻo DHA ka aila algae ka mea nui i kēia manawa. I loko o ka waiu waiu me DHA, pono ka helu DHA e hiki i ka 0.2%-0.5% o ka nui o nā ʻakika momona, ma kahi o 20-60mg/L.

ʻAila iʻa kai hohonu

Nui ka ʻaila iʻa i ka DHA a me ka EPA (eicosapentaenoic acid), a ʻo ka ʻaila iʻa mai ka iʻa hohonu. Me ka piʻi nui ʻana o ka hoʻomohala honua, ua ʻoi aku ka nui o ka haumia o ke kaiapuni. I nā makahiki i hala iho nei, ua ʻike nā ʻāina lawaiʻa nui e like me Kanada a me Iapana i ka iʻa hohonu i loaʻa i ka nui o nā mea haumia organik a me ka mercury metala kaumaha, a ʻo ka hapa nui o ia mau mea he momona. Ua paʻi ka puke pai ʻepekema ʻepekema Pelekane "Photochemical Layer" i kahi hōʻike noiʻi e ka mea ʻepekema Pelekane ʻo Jacobs. Ua hōʻiliʻili lākou i nā ʻaila iʻa 44 mai nā ʻāina he 15 a ʻike lākou aia nā mea haumia chlorine organik, a me ka dioxin (Doixin) a me ka toxaphene. E kali. Eia kekahi, loaʻa i ka aila iʻa kekahi hapa o ka EPA, ʻo ia hoʻi kahi momona momona unsaturated. Ua ʻike nā haʻawina mua e pili ana ka nui o ka lawe ʻana i ka EPA i ke kaumaha o nā pēpē.

 

He aha nā meaʻai kiʻekiʻe loa ma DHA?

ʻO ka DHA precursor (α-linolenic acid) ma ke ʻano i loaʻa nui i nā nati a me nā aila mea kanu, e like me ka aila linseed, nā hua sunflower, nā pīni a me nā huaʻai ʻē aʻe. Hiki ke hoʻololi ʻia i ka DHA i loko o ke kino, hiki ke hoʻohana ʻia e ke kino. Eia naʻe, ʻaʻole maopopo ka helu hoʻololi ʻana o ka α-linolenic acid. ʻO ka ʻoiaʻiʻo, ʻo ka alpha-linolenic acid i loko o nā nati a me nā momona ʻē aʻe he mea nui e like me ka hoʻohui pololei o DHA, a he kumu nui ia no ke kino e loaʻa ai ka DHA lawa.

Kahi e kūʻai ai i ka limu dha

ʻOiai hiki i kekahi mau iʻa moana ke synthesize n-3 polyunsaturated fatty acids e like me DHA a me EPA, ʻo ka DHA a me ka EPA i hōʻiliʻili ʻia i loko o ko lākou kino ke kumu nui mai kā lākou meaʻai. ʻO nā mea hana mua i loko o ke kaulahao meaʻai kai-nā microorganisms moana nā mea hana mua o n-3 polyunsaturated fatty acids. No laila, ʻo ka ʻimi ʻana i nā kumu hou o n-3 polyunsaturated fatty acids i loko o nā microorganisms kai, ua lilo i wahi wela noiʻi hou. Hoʻomaka e haʻi ʻia nā manaʻo o ka "ʻaila microbial" a me ka "ʻaila cell single". Ua hoʻokaʻawale ʻia kekahi ʻano microorganisms kai waiwai i ka DHA a me ka EPA, ʻo ia hoʻi kekahi mau haʻi kai haʻahaʻa haʻahaʻa a me nā microalgae. Hoʻohālikelike ʻia me ka ʻaila iʻa, loaʻa i ka ʻaila algae DHA kekahi mau mea maikaʻi ʻole o ka aila iʻa. ʻO YANGGE mea hana maʻemaʻe maoli, nā meaʻai ʻōmaʻomaʻo me nā koena metala kaumaha, vegan, ʻaʻohe ʻala iʻa, he kumu hoʻohou hoʻomau, a hilinaʻi ke kumu.
