Application Note: Determination of Organic Acids in Fruit Juices and Wines by High-Pressure IC
2 May 2014
The determination of organic acids plays an important role when testing the authenticity of fruit juices and wines. Certain fruit juices, such as those obtained from pomegranate and various types of berries, are popular because of their high levels of antioxidants and the resulting putative health benefits. The high economic value and the large market demand for these juices make them a likely target for adulteration. This application note describes method development to determine organic acids in fruit juices and wines using ion chromatography (IC) with suppressed conductivity detection.
