Etylmaltolbruk og syntese

Kjemiske egenskaper	Hvit krystallinsk solid med karakteristisk, veldig søt, karamellaktig lukt og smak. Ved fortynning har den en søt, fruktaktig smak og lukt.
Kjemiske egenskaper	It 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 a one-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
Kjemiske egenskaper	Ethyl maltol has a very 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.
Bruker	Ethyl Maltol is a flavoring agent that is a white, crystalline powder. it has a unique odor and a sweet 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.
Bruker	Flavor 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.
Forberedelse	Flere synteser er utviklet for forberedelse. I en en-krukeprosess, for eksempel, behandles etylfurfurylalkohol med halogen for å gi 4-halo-6-hydroksy-2-etyl-2H-pyran-3 (6H) -on, som ikke trenger å isoleres og kan omdannes til etylmaltol ved vandig hydrolyse.
Production Methods	Unlike maltol, ethyl maltol does not occur naturally. It may be prepared by treating a-ethylfurfuryl alcohol with a halogen to produce 4-halo-6-hydroxy-2-ethyl-2H-pyran-3(6H)-one, which is converted to ethyl maltol by hydrolysis.
Smakterskelverdier	Taste characteristics at 70 ppm: sweet, burnt cotton, sugar candy-like with jamy, strawberry notes.
Pharmaceutical Applications	Etylmaltol brukes i farmasøytiske formuleringer og matvarer som et smaksmiddel eller smaksforsterker i applikasjoner som ligner på maltol. Den har en smak og lukt4 - 6 ganger så intens asmaltol. Etylmaltol brukes i orale siruper ved en konsentrasjon på ca. 0,004% vekt / volum og også ved lave nivåer i parfymeri.
Safety Profile	Moderat giftig ved inntak og subkutan vei. Mutasjonsdata rapportert. Ved oppvarming til nedbrytning avgir den skarp røyk og irriterende røyk.
Sikkerhet	In 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 2 mg/kg bodyweight. LD50 (kylling, oral): 1,27 g / kg LD50 (rat, oral): 1.15 g/kg LD50 (mus, oral): 0,78 g / kg LD50 (mus, SC): 0,91 g / kg
Kjemisk syntese	Fra kojinsyre
Oppbevaring	Løsninger kan bestores i glass- eller plastbeholdere. Bulkmaterialet skal oppbevares i en godt lukket beholder, beskyttet mot lys, på et kjølig, tørt sted.
Regulatory Status	GRAS listed. Included in the FDA Inactive Ingredients Database (oral syrup).
