Ethyl valerate is also known as the green apple flavor. Microwave spectrum of ethyl valerate, observed by molecular beam Fourier transform microwave spectroscopy, has been reported. |
| Questions And Answer | Back Directory | [Aroma]
Powerful and diffusive, ethereal-fruity,
Apple-like odor with a remote resemblance to
Pineapple. Esters with traces of free acids will
show this very perceptibly in the odor, not so
conspicuously in the flavor (in aqueous media).
Sweet and somewhat pungent-fruity, AppleIike, almost "gassy"-ethereal taste. In extreme
dilution, the taste is merely sweet fruity. |
