Abstract

Soft drinks are consumed daily in Nigeria due to their characteristic taste, palatability, affordability and thirst quenching potential. This study quantifies the amount of electrolytes of Biochemical significance in selected soft drinks sold in Port Harcourt and their pH values. The samples included six frequently consumed soft drinks; (Coke, Sprite, Fayrouz, Mountain-Dew, Fanta and Pepsi). The results showed that the samples contain relatively high amount of Sodium(Na+) ranging from 88mmol/l to 41mmol/l with  a mean of 59.83mmol/l, Potassium(K+) was relatively low in the samples with values ranging from 1.9mmol/l to 0.01mmol/l with a mean of 0.48mmol/l, Calcium(Ca2+) was relatively low in the samples with values ranging from 1.5mmol/l to 0.5mmol/l with a mean of 0.88mmol/l, Magnesium(Mg2+) was relatively very low in the samples with values ranging from 0.40mmol/l to 0.01mmol/l with a mean of 0.11mmol/l, Bicarbonate(HCO32-) concentration was low in the samples with values ranging from 0.04mmol/l to 0.01mmol/l  with a mean of 0.025mmol/l, Chloride (Cl-) was relatively high in the samples with values ranging from 24.50mmol/l to 2.50mmol/l with a mean of 12.23mmol/l, Phosphate (HPO42-) content of the drinks were relatively moderate with values ranging from 6.20mmol/l to 0.11mmol/l with a mean of 2.25. The pH of the samples showed they were acidic with pH ranging from 4.0 to 2.40 with a mean of 3.4. The results show that soft drinks are good sources of electrolytes.
