FEMA 2510 Chemical Properties,Usage,Production
Aroma
Sweet fruity, winey-green "fermented Apple"-like, overall very pleasant odor. Sweet fruity, ethereal, green-winey taste, reminiscent of Apple or Apple wine.
Description
Geranyl acetoacetate is prepared from diketene and geraniol in the presence of the sodium salt of geraniol.
Physical properties
Colorless oily liquid. Almost insolubIe in water, soluble in alcohol, Propylene glycol and oils.
Uses
FEMA 2510 finds some use in flavor compositions, mainly as a trace component in various fruit flavors, not only Apple. It introduces a certain note of natural pleasant "overripe" or "fermented" character to many fruit flavors, and its low rate of volatility makes it a good fixative for the more volatile and common components in these fruit flavors. Concentration in the finished product may be in the range of 1 to 10 ppm.
Definition
ChEBI: A monoterpenoid that is the carboxylic ester obtained by the formal condensation of geraniol with acetoacetic acid.
Preparation
From diketene and geraniol in the presence of the sodium salt of geraniol.
Safety Profile
A skin irritant. When heated to decomposition it emits acrid smoke andirritating fumes.
