Ethyl Maltol as aFlavorings can still preserve its sweetness and aroma after it is dissolved in the water. And its solution is stable. As an ideal food additive, Ethyl Maltol features safety, innocuity, wide application, good effect and little dosage. It also can be used as good flavour agent in tobacco, food, beverage, essence, wine, daily-use cosmetics and so on.AppearanceWhite crystalline powderAssay≥99.2%melting point89-92Water≤0.30%residue on lgnition≤0.10%Heavy metals≤10ppmLead≤5ppmArsenic≤2ppmcadmium≤1ppmmercury≤1ppmEthyl maltol Basic informationProduct Name:Ethyl maltolSynonyms:2-ethyl-3-hydroxy-4-pyranone;6-ETHYL-3-HYDROXY-2-METHYL-4H-PYRAN-4-ONE;3-HYDROXY-2-ETHYL-4-PYRONE;Ethylmaltol (Subject To Patent Free);3-Hydroxy-2-ethyl-4-pyrone,ethyl maltol;ETHYL MALTOL 99+% FCC;ETHYLMALTOL FCCIV;PYRAN-4-ONE,3-HYDROXY-2-METHYL-,2-ETHYLESTERCAS:4940-11-8MF:C7H8O3MW:140.14EINECS:225-582-5Product Categories:Food and Feed Additive;Food &Feed ADDITIVES;Food &Flavor Additives;Building Blocks;Chemical Synthesis;Heterocyclic Building Blocks;Pyrans;Food AdditivesMol File:4940-11-8.molEthyl maltol Chemical PropertiesMelting point85-95 °C(lit.)Boiling point196.62°C (rough estimate)density1.1624 (rough estimate)FEMA3487 |ETHYL MALTOLrefractive index1.4850 (estimate)pka8.38±0.10(Predicted)formneatJECFA Number1481Merck14,3824CAS Database Reference4940-11-8(CAS Database Reference)NIST Chemistry Reference4H-pyran-4-one, 2-ethyl-3-hydroxy-(4940-11-8)EPA Substance Registry System4H-Pyran-4-one, 2-ethyl-3-hydroxy- (4940-11-8)Safety InformationHazard CodesXnRisk Statements22Safety Statements36WGK Germany3RTECSUQ0840000HS Code29329990ToxicityLD50 orally in male mice, male rats, female rats, chicks (mg/kg): 780, 1150, 1200, 1270 (Gralla)MSDS InformationProviderLanguageSigmaAldrichEnglishEthyl maltol Usage And SynthesisChemical PropertiesWhite crystalline solid with characteristic, very sweet, caramel-like odor and taste. In dilute solution it possesses asweet, fruitlike flavor and odor.Chemical PropertiesIt forms white crystals (mp 90-91°C) with very sweet caramel-like odor, four to six times more potent than maltol. Several syntheses have been developed for its preparation. In aone-pot process, for example, ??-ethylfurfuryl alcohol is treated with halogen to give 4-halo- 6-hydroxy-2-ethyl-2H-pyran-3(6H)-one, which need not be isolated and can be converted to ethylmaltol by aqueous hydrolysisChemical PropertiesEthyl maltol has avery sweet, fruit-like odor of immense tenacity and sweet, fruity taste with initial bitter-tart flavor; rapid loss of flavor per se. It is four to six times more potent than maltol.UsesEthyl Maltol is aflavoring agent that is awhite, crystalline powder. it has aunique odor and asweet taste that resembles fruit. the melt- ing point is 90°c. it is sparingly soluble in water and propylene gly- col and soluble in alcohol and chloroform. it is obtained by chemical synthesis.UsesFlavor and fragrance enhancer in foods, especially baked goods, beverages, and synthetic berry and citrus flavorings; minimizes undesirable flavors in tobacco products, cough syrup, vitamins, cosmetics, and saccharin-containing products.PreparationSeveral syntheses have been developed for its preparation. In aone-pot process, for example, ??-ethylfurfuryl alcohol is treated with halogen to give 4-halo- 6-hydroxy-2-ethyl-2H-pyran-3(6H)-one, which need not be isolated and can be converted to ethylmaltol by aqueous hydrolysis.Production MethodsUnlike maltol, ethyl maltol does not occur naturally. It may be prepared by treating a-ethylfurfuryl alcohol with ahalogen to produce 4-halo-6-hydroxy-2-ethyl-2H-pyran-3(6H)-one, which is converted to ethyl maltol by hydrolysis.Taste threshold valuesTaste characteristics at 70 ppm: sweet, burnt cotton, sugar candy-like with jamy, strawberry notes.Pharmaceutical ApplicationsEthyl maltol is used in pharmaceutical formulations and food products as aflavoring agent or flavor enhancer in applications similar to maltol. It has aflavor and odor 4-6 times as intense asmaltol. Ethyl maltol is used in oral syrups at concentrations of about 0.004% w/v and also at low levels in perfumery.Safety ProfileModerately toxic by ingestion and subcutaneous routes. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.SafetyIn animal feeding studies, ethyl maltol has been shown to be well tolerated with no adverse toxic, reproductive, or embryogenic effects. It has been reported that while the acute toxicity of ethyl maltol, in animal studies, is slightly greater than maltol, with repeated dosing the opposite is true. The WHO has set an acceptable daily intake for ethyl maltol at up to 2mg/kg bodyweight.LD50 (chicken, oral): 1.27 g/kgLD50 (rat, oral): 1.15 g/kgLD50 (mouse, oral): 0.78 g/kgLD50 (mouse, SC): 0.91 g/kgChemical SynthesisFrom kojic acidstorageSolutions may be stored in glass or plastic containers.
