Organic acids serve a variety of functions in food such as preservation, flavor, and nutrition. Some organic acids are naturally present in fruit and offer many health benefits. To evaluate organic acid content across fruit juices, the proper analytical tools for product investigation are necessary. Eurofins EAG Laboratories can identify and quantify the different organic acids using High Performance Liquid Chromatography (HPLC). This note demonstrates the abilities that Eurofins EAG has to quickly and accurately screen for common organic acids in fruit juices.
In this study, the objective was to screen four types of fruit juices (tomato, apple, orange, and coconut) for organic acids using high performance liquid chromatography with diode array detection (HPLC-DAD). A summary of test samples is presented in Table 1.
