Abstract
We have synthesized unsaturated aldehydes and ketones by condensation of the aldehydes which are known to be contained in soy, and found that the condensation product of furfural and isovaleral had soy-like flavor. On the other hand we have obtained the reaction product of crotonaldehyde and methylmercaptan whose flavor is also resembling to that of soy. We can make a very good soy flavor by mixing these two compounds.
