Natural Occurrence of Beauvericin and Enniatins in Corn- and Wheat-Based Samples Harvested in 2017 Collected from Shandong Province, China.

ABSTRACT: Totals of 158 corn and corn-based samples and 291 wheat and wheat-based samples from Shandong province, China in 2017 were analyzed for five mycotoxins including beauvericin (BEA), enniatin A (ENA), enniatin A₁ (ENA₁), enniatin B (ENB), and enniatin B₁ (ENB₁) by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). BEA was the predominant toxin detected, followed by ENB, ENA₁, ENA, and ENB₁. Corn and corn-based samples were more easily contaminated by BEA with an average concentration of 65.26 µg/kg, compared with that in wheat and wheat-based samples (average = 0.41 µg/kg). Concentrations of BEA, ENA, and ENB₁ in corn kernels, flours, and flakes were significantly different (Kruskal⁻Wallis Test, p < 0.05), as well as for BEA, ENA, ENB, and ENB₁ in wheat kern
