Estimate the Contents of Citric acid and pH values in some Soft Drink Juice Samples Collected from Libyan Markets

Abstract

The foods contain different types of chemical materials and additives. Many of these compounds have different effects on human health when they are above the recommended limits given by some world Organizations as the WHO and FAO. This is study aims to estimate citric acid and pH values in juice samples collected from some Libyan markets, about Twelve samples were selected including different brands, the citric acid contents were measured by Titration method, the results of this study recorded that the concentrations of Citric acid were ranged between (0.0832 – 0.5440 g/mL) and the PH values ranged between (2.6 – 3.6), the citric samples were lower than the values of WHO /FAO limitations
