ABSTRACT
We show that the concentration of total free fatty acids (FFAs) in sake produced by yeast with high productivity of ethyl caproate could be approximated by the concentration of 2 FFAs, caproic and caprylic acids. Measurement of the total FFAs concentration by an enzymatic method proved useful for both estimating the ethyl caproate concentration in sake and also for yeast breeding.
