Use of ebulliometer for alcohol determination in coconut toddy

Abstract

Ebulliometers are used in the industry for estimation of Alcohol in toddy. This method was compared with hydrometer and pycnometer methods for estimation of alcohol in toddy. The ebulliometer method appeared to be accured to be accurate for toddy containing 6 to 8perc. (v/v) alcohol. A calibration curve is presented for reading the actual alcohol content when the estimated value using the ebulliometer is known. The readings obtained by the hydrometer method did not vary significantly from those obtained by the ebulliometer method.
