Whakataki hua
Ko te 1-Methylnicotinamide chloride he matū methylated o te nicotinamide, e tohuhia ana e te hanganga tote ammonium quaternary pumau. He takawaenga nui tēnei i roto i te ako i te pākia o te nicotinamide. Nā tōna wairewatanga wai me te pumau matū pai, he mea pai hei taputapu rangahau matū koiora.
He matū tūturu te 1-MNA i roto i te tinana tangata, e mahi ana hei hua noa o te pākia o te niacin. Hei takawaenga i roto i tēnei ara pākia, ka tukatukahia anō te 1-MNA e te aldehyde oxidase hei whakaputa i ngā matū whaihua pērā i te N-methyl-2-pyridone-5-carboxamide (2PY) me te N-methyl-4-pyridone-3-carboxamide (4PY), ka puta i te mutunga mā te pūnaha mimi.

Āhuatanga
(1) Te wairewatanga ki te wai: Ka wairewa ngāwari ki te wai me ngā whakarewa waro porotaka.
(2) Te Pūmautanga: Ka pumau i raro i ngā āhuatanga pāmahana rūma engari me penapena ki roto i ngā taiao ātete makuku.
(3) Haumarutanga: Kua whakahaerehia e te Kotahitanga o Ūropi tētahi aromatawai pūtaiao mō te 1-MNA hei wāhanga kai hou. E ai ki te Ture EU (EC) Nama 258/97, e kiia ana he haumaru te 1-MNA mō te kai, me te nui rawa o te kai e taunakitia ana mō te pakeke i ia rā ko te 58 mg, ko te nuinga hei whakamahi i roto i ngā tāpiringa kai.
Ngā tono
Ko te 1-Methylnicotinamide chloride (whakarāpopototanga ko MNC) he matū methylated o te nicotinamide. Ka taea te kimi i te 1-MNA mā roto i ngā tikanga pēnei i te high-performance liquid chromatography (HPLC) me te enzyme-linked immunosorbent assay (ELISA). He pūmanawa tōna mō ngā tono i roto i ngā rāngai kai me ngā hua hauora. I roto i te umanga kai, ka mahi pea ia hei antioxidant hei whakaroa i te waikura lipid me te tiaki i te kounga kai. Nā ōna āhuatanga hanganga, ka taea hoki te mahi hei wāhanga mahi i roto i ngā kai kua whakakahangia ki te kai. Heoi anō, e whakaatu ana te 1-MNA i ngā mahi i roto i te whakahaere i te pākia me te whakapai ake i ngā āhua ā-tinana, e tuku ana i te uara mō te whanaketanga i roto i ngā kai mahi me ngā tāpiringa kai e mau ana i ngā kereme hauora.
I whakatauhia e te aromatawai a te EU ko te kai i te 58 mg o te 1-MNA mai i ngā tāpiringa kai i ia rā, kāore pea e pā kino ki te hauora o te tangata, ā, kua whakaurua mana ki roto i te rārangi kai hou a te EU.
Hei ngota koiora nui me te paerewa tohutoro, he whānui ngā tono a te 1-methylnicotinamide chloride i roto i te rangahau pūtaiao, te whanaketanga rongoā, me te umanga tāpiringa kai. Nā tōna aromatawai haumaru kua tautuhia pai me ngā mahi koiora kanorau kua whakatūria hei kaupapa whai hua mō te rangahau me te wāhanga mō ngā tono rerekē.
