Orange juice is a hugely popular, widely consumed, and high price commodity typically traded in a concentrate form making it highly susceptible to adulteration.
Abstract
A simple, direct, and rapid method is given for the analysis of citrus oils for the fungistat biphenyl by high-speed liquid chromatography. The method is extended to orange juice and various “dry flavors” by an extraction procedure. Analytical limits are <1 ppm without need for any cleanup or concentration steps.
