3-Hydroxy-2-Methyl-4-Pyrone (Maltol) (CAS: 118-71-8) waxaa loo isticmaalaa sida cuntada lagu daro, dhadhanka, dhadhanka xumeeyayaasha iyo udgoonka, waxaa loo isticmaali karaa dhadhanka tubaakada.
Maltol waxaa si weyn loogu isticmaalaa dhadhamiyeyaasha si loo hagaajiyo dareenka afka iyo in kor loogu qaado dhadhanka nacnaca iyo cuntooyinka la dubay ee wax soo saarka cuntada iyo cabitaannada fudud ee warshadaha cabitaanka.Waxa loo istcimaalaa dhex dhexaad ka ah dawooyinka soo saarista daawada.Waxaa loo isticmaalaa sidii wakiilka dhadhanka ee warshadaha qurxinta iyo daryeelka shakhsi ahaaneed si kor loogu qaado dhadhanka.Marka loo eego guddiga FEEDAP, maltol waa badbaado in lagu daro si loogu quudiyo dhammaan noocyada xayawaanka heerka isticmaalka caadiga ah ee 5 mg/kg quudinta.
Maltol waa nooc ka mid ah kobcinta dhadhanka ballaadhan oo ay ku jirto korodhka dhadhanka, kobcinta iyo macaanaynta.Waxaa loo isticmaali karaa maaddooyinka dhadhanka, kiimikooyinka cadarka iwm oo si ballaaran loogu dabaqo tubaakada, khamriga, waxyaabaha la isku qurxiyo, iyo warshadaha kale, taasoo muujineysa saameyn muuqata.
Maltol iyo Ethyl Maltol ayaa inta badan lagu daraa cunto dhadhamin ahaan cuntooyinka la dubay, jalaatada iyo nacnaca.Qadarka lagu daro maltol waa qiyaastii 110μg/kg.Marka loo eego xisaabinta, celceliska cadadka maltol iyo ethyl maltol waa qaadashada maalinlaha ah 5-29 mg, laakiin dadka qaar, heerka isticmaalka dhabta ah wuxuu noqon karaa dhowr jeer celcelis ahaan.
Waxa laga yaabaa in ay xasaasi u noqoto gaadhista iftiinka iyo hawada daba dheeraada.Xoogaa ku milmay biyaha heerkulka qolka.Si xor ah ugu milmay biyaha kulul [Merck].Waxoogaa ku milmay biyo qabow.
Xogta Badbaadada:Sumo dhexdhexaad ah marka la nuugo, intraperitoneal, iyo dariiqyada maqaarka hoostiisa.Maqaar cuncun leh.Xog-is-beddelka aadanaha ayaa la sheegay.Marka loo kululeeyo si uu u burburo waxay soo daysaa qiiq qallafsan iyo qiiq xanaaq badan.
Kaydinta:Xalalka Maltol waxa lagu kaydin karaa weelal dhalo ah ama caag ah.Waxyaabaha ugu badan waa in lagu kaydiyaa weel si fiican u xiran, oo laga ilaaliyo iftiinka, meel qabow oo qallalan.
Aan waafaqsanayn:Xalalka isku dhafka ah ee weelasha biraha ah, oo ay ku jiraan qaar ka mid ah darajooyinka birta ah, ayaa laga yaabaa inay midab beddelaan kaydinta.
Xaalada Sharci:GRAS ku qoran.Waxaa ku jira kaydka xogta aan firfircoonayn ee FDA (xalalka afka iyo sharoobada).Lagu daray Liiska Kanadiyaanka ee Walxaha aan Dawaynta ahayn ee La Aqbali Karo.
