Comparative Study on the Estimation of Ethanol in Fermented Samples by Different Methods

Five known methods such as specific gravity method, Kozelka
and Hine method, Caputi's method, Gas chromatographic and
enzymatic methods have been used for the estimation of ethanol in different fermented samples, keeping the specific gravity method as a reference. Of these methods, gas chromatographic method was simpler, more rapid, more sensitive and less expensive than the other methods. The data obtained were statistically analysed and found to be in favour of the gas chromatographic method.
