Chemische Eigenschaften
Beige crystalline powder
Chemische Eigenschaften
Colorless needle-like or plate-like crystals. M.P. 77° c. Vanillin acetate has a mild, balsamic, floral odor with a nonvanillin flavor. Poorly soluble in water, soluble in alcohol and oils,
Occurrence
Reported found in shoyu (fermented soya hydrolysate).
Verwenden
Vanillin Acetate is a synthetic flavoring agent that is moderately stable, white to yellow crystals of vanilla odor. it should be stored in glass or polyethylene-lined containers. it is used in flavors for vanilla note, with application in beverages, ice cream, candy, and baked goods at 11–28 ppm.
Verwenden
Vanillin acetate has been used in preparation of:
- 2-nitrohomovanillic acid
- 2-nitrovanildin acetate
- 2-nitro-3,4-duimethoxybenzaldehyde
Application
Vanillin acetate is used in spice flavor blends and in Vanilla flavor compositions as a modifier for Vanillin and related derivatives. lt tends to reduce the overall power of the flavor, but also improve the total picture in "freshening-up" the heavy aroma of Vanillin, Ethylvanillin, etc.
Definition
ChEBI: An acetate ester obtained by the formal condensation of phenolic group of vanillin with acetic acid.
synthetische
By acetylation of vanillin or by oxidation of isoeugenyl acetate with chromic acid in the presence of sulfanilic acid; also by electrolytic reduction of vanillin, followed by acetylation of vanillyl alcohol.
Taste threshold values
Taste characteristics at 40 ppm: sweet, vanilla, creamy and powdery with a balsamic nuance.
Allgemeine Beschreibung
Chemoselective reduction of vanillin acetate using sodium borohydride has been reported.
Synthese
Vanillin acetate is synthesized by Vanillin by electrolytic reduction, followed by Acetylation of the Vanillyl alcohol.
Solubility in organics
Soluble in alcohoi and oils
