High-speed analysis of food additives in functional beverage by UHPLC with photodiode array detection

There are a number of food additives used in beverage to add good flavor and taste, good appearance, long shelf life, and nutritional enrichment. However, those food additives may have a bad effect on health if not properly controlled. Therefore, they are regulated by the Food Sanitation Act.

In this report, food additives in functional beverage are measured and analyzed by ultra high-performance liquid chromatography with photodiode array detection, which enables high speed data acquisition rate at 100 spectra/sec.
