Ua makemake nui ʻia ka waiu kokoleka e nā mea kūʻai aku ma ka honua holoʻokoʻa ma muli o kona ʻono a me ka momona.Hiki ke loaʻa kēia mea ʻai i nā ʻano mea ʻai a pau, akā ʻaʻole maikaʻi loa.ʻO ka ʻokoʻa, loaʻa i ke kokoleka ʻeleʻele nā ​​kiʻekiʻe o nā pūhui phenolic, hiki ke hāʻawi i nā pōmaikaʻi olakino antioxidant, akā ʻoi aku ka paʻakikī o ka kokoleka ʻawaʻawa.I kēia lā, hōʻike ka poʻe noiʻi i kahi ala hou o ka hui ʻana i ka waiu kokoleka me nā ʻili pīkī ʻōpala a me nā mea ʻōpala ʻē aʻe e hoʻomaikaʻi i kāna mau waiwai antioxidant.
Ua hōʻike nā mea noiʻi i kā lākou hopena ma ka American Chemical Society (ACS) Virtual Conference and Expo in Fall 2020. ʻO ka hālāwai kūkā i hoʻopau i nehinei i hōʻike ʻia i kahi ākea o nā kumuhana ʻepekema, me ka ʻoi aku o 6,000 mau haʻawina.
"Ua hoʻomaka ka manaʻo o ka papahana me ka hoʻāʻo ʻana i ka hana olaola o nā ʻano ʻōpala mahiʻai, ʻoi aku ka nui o nā ʻili pīkī," wahi a Lisa Dean, ka mea noiʻi nui o ka papahana."ʻO kā mākou pahuhopu mua ka lawe ʻana i nā phenols mai ka ʻili a loaʻa kahi ala e hui pū ai me ka meaʻai."
Ke kālua a hana ka poʻe hana i nā pīkī e hana i ka pata pīnī, nā candies, a me nā huahana ʻē aʻe, hoʻolei lākou i ka ʻili ʻulaʻula pepa e wahī i ka pī i loko o kā lākou pūpū.Hoʻolei ʻia nā kaukani o nā ʻili pīnī i kēlā me kēia makahiki, akā no ka loaʻa ʻana o 15% phenolic pūhui, ʻo ia kahi ʻoihana gula kūpono no ka hana biological antioxidant.ʻAʻole hāʻawi wale nā ​​antioxidants i nā pono olakino anti-inflammatory, akā kōkua pū kekahi i ka pale ʻana i ka meaʻai.
ʻO ka ʻoiaʻiʻo, ʻo ka hele maoli ʻana o nā pūhui phenolic e hāʻawi i ke kokoleka ʻeleʻele i kahi ʻono ʻawaʻawa.Ke hoʻohālikelike ʻia me ka kokoleka waiū hoahānau, ʻaʻohe ona momona a me ke kō.ʻOi aku ke kumukūʻai o nā ʻano ʻeleʻele ma mua o nā ʻano waiu no ka nui o ka nui o ka koko, no laila hiki i ka hoʻohui ʻana i nā ʻōpala e like me ka ʻili pīnī ke hāʻawi i nā pōmaikaʻi like a ʻaʻohe kumu kūʻai.ʻAʻole ʻo ka ʻili pīkī wale nō ka ʻōpala meaʻai hiki ke hoʻonui i ka waiū kokoleka ma kēia ʻano.Ke ʻimi nei nō hoʻi nā mea noiʻi i nā ala e unuhi a hoʻokomo i nā pūhui phenolic mai ke kahua kofe ʻōpala, ke kī ʻōpala a me nā koena meaʻai ʻē aʻe.
No ka hana ʻana i kā lākou kokoleka waiu i hoʻonui ʻia i ka antioxidant, ua hana ʻo Dean a me kāna mau mea noiʻi ma ka United States Department of Agriculture (USDA) Agricultural Research Service me ka hui pīkī e kiʻi i nā ʻili pīkī.Mai laila, wili lākou i ka ʻili a lilo i pauka a laila hoʻohana i ka 70% ethanol e wehe i nā pūhui phenolic.Hiki ke hoʻohana ʻia ke koena lignin a me cellulose i meaʻai holoholona no ka roughage.Hoʻohana pū lākou me nā mea hoʻoheheʻe kofe kūloko a me nā mea hana kī e hoʻohana i nā ʻano like e unuhi i nā antioxidants mai kēia mau mea no ka loaʻa ʻana o ka pā kofe a me nā lau kī.Hoʻohui ʻia ka pauka phenolic me ka maltodextrin meaʻai maʻamau i mea e maʻalahi ai ka hoʻokomo ʻana i loko o ka huahana waiu kokoleka hope loa.
No ka hōʻoia ʻana i hiki i kā lākou meaʻai hou ke hele i ka ʻahaʻaina meaʻai, ua hana nā mea noiʻi i kahi kokoleka kū hoʻokahi ma kahi o ka neʻe ʻana o nā phenols mai ka 0.1% a i ka 8.1%, a loaʻa i kēlā me kēia kanaka ke ʻano o ka ʻono.ʻO ke kumu o ka hana ʻana i ka pauka phenolic i ka ʻono o ka waiu kokoleka i ʻike ʻole ʻia.Ua ʻike nā mea hoʻāʻo ʻono e hiki ke ʻike ʻia ka nui o ka ʻoi aku ma mua o 0.9%, akā ʻo ka hoʻohui ʻana o ka resin phenolic ma kahi ʻano o 0.8% e hōʻino maikaʻi i nā pae kiʻekiʻe o ka hana olaola me ka ʻole o ka ʻono a i ʻole ke ʻano.ʻO ka ʻoiaʻiʻo, ʻoi aku ma mua o ka hapalua o nā mea hoʻāʻo ʻono i makemake i ka 0.8% phenolic milk chocolate ma mua o ka waiu kokoleka hiki ʻole ke kāohi.He ʻoi aku ka nui o ka hana antioxidant kemika ma mua o ka nui o nā kokoleka ʻeleʻele.
ʻOiai he mea hoʻoikaika kēia mau hopena, ua ʻae pū ʻo Dean a me kāna hui noiʻi he pilikia koʻikoʻi ka maʻi maʻi ʻai ka pīni.Ua hoʻāʻo lākou i ka pauka phenolic i hana ʻia mai ka ʻili no ka loaʻa ʻana o nā allergens.ʻOiai ʻaʻole i loaʻa nā allergens, ua ʻōlelo lākou e hoʻopaʻa inoa ʻia nā huahana i loaʻa i ka ʻili pīkī.
A laila, hoʻolālā ka poʻe noiʻi e ʻimi hou aku i ka hoʻohana ʻana i ka ʻili pīkī, ka pā kofe a me nā mea ʻino ʻē aʻe no nā meaʻai ʻē aʻe.ʻO ka mea nui, manaʻolana ʻo Dean e hoʻāʻo inā hiki i nā antioxidants i loko o nā ʻili pīnī ke hoʻolōʻihi i ke ola o nā pata nut, hiki ke popopo koke ma muli o ko lākou momona momona.ʻOiai ua mamao loa ka hoʻolako ʻana i kāna kokoleka hoʻonui a pono e hoʻopaʻa ʻia e ka hui, manaʻolana lākou e hoʻomaikaʻi maikaʻi ʻia kā lākou mau hana i ka waiū kokoleka ma nā hale kūʻai kūʻai.
