Abstract: The physicochemical analysis of palm wine from three Local Government Areas of Rivers State: Eleme, Obio-Akpo and Etche were carried out at 0 hour, 24hours, 48hours and 72 hours. pH and electrical conductivity readings of the samples were determined by corning pH meter model 430 and DDS 307 conductivity meter, Total Dissolved Solids (TDS) by APHA standard methods. The TDS in all the samples of the palm wine increased from 500mg /l to 1260mgl-1, 400mgl-1 to 1406mgl-1 and 600mgl-1 to1322mgl-1 for Eleme, Obio-Akpo and Etche LGAs respectively. The pH decreased progressively from 6.2 to 3.3, 6.4 to3.1 and 6.3 to3.2 in all the samples showing increase in acidity of the palm wines over the time. Electrical conductivity increased in all the samples from1000μScm-1 to 2520μScm-1, 800μScm-1to 2812μScm-1and 1200μScm-1to 2600μScm-1 respectively over the test period. The chloride concentrations of all the samples decreased from 700mg/l to 300mg/l, 400mg/l to180mg/l and 650mg/l to 300mg/l respectively. This is because of the increase in acidity since increase in acidity gives rise to decrease in alkalinity. The salinity is an attribute of the chloride concentration and as such decreased as the chloride concentration decreased. Meanwhile, the results showed very high chloride concentration, electrical conductivity and salinity for all the fresh palm wines. Palm wine from the areas of study showed presence of vitamin C in the mean values of: 0.0011 g/dm3, 0.0012g/dm3, 0.0014g/dm3 for Eleme, Obio/Akpo and Etche LGAs respectively.
