Patulin in Apple Juice from Roadside Stands in Wisconsin

Abstract
High-performance liquid chromatography was used to determine the amount of patulin in 40 samples of apple juice sold at roadside stands in Wisconsin. Samples were taken during juice-producing seasons in 1976 and 1977. Nine of 11 samples obtained in 1976 contained from a trace (approximately 10 μg) to 350 μg of patulin per liter. Fourteen of 29 samples obtained in 1977 contained from a trace to 204 μg of patulin per liter. The average concentration of patulin in all samples was 51 μg/l; most samples contained less than 50 μg/l.
