Analysis was performed using an LC-MS/MS system consisting of a Waters Acquity UPLC coupled to a Xevo TQ-S tandem mass spectrometer (Waters, Milford, MA, USA). Two to three multiple reaction monitoring (MRM) transitions were measured per analyte in positive electrospray ionization (ESI) mode. The ion source parameters were set as follows: capillary voltage, 3.0 kV; source temperature, 150 °C; source offset, 60 V; desolvation temperature, 600 °C; cone gas flow, 150 l/h; desolvation gas flow, 800 l/h; collision-induced dissociation (CID) gas, argon, 4.3 × 10-3 mbar (0.17 ml/min). See Table S4 for detailed information on MRM transitions, MS settings and retention times.
The analytes were separated on an Acquity UPLC BEH C18 1.7 μm 150 × 2.1 mm column (Waters, Milford, MA, USA). The solvents used were (A) ammonium carbonate buffer (10 mmol/l, pH 9.0 ± 0.1) and (B) acetonitrile. At a flow rate of 0.4 ml/min, the linear gradient conditions were: 0.0 min, 0% B; 0.1 min, 5% B; 3.0 min, 10% B; 7.0 min, 24% B; 9.0 min, 30% B; 12.0 min, 70% B; 12.1 min–14.2 min, 0% B. The injection volume was 2 μl, the column oven temperature 50 °C. MassLynx 4.2 and TargetLynx XS software (Waters, Milford, MA, USA) were used for, respectively, data acquisition and processing.

Lipid extracts were dissolved in 1 mL chloroform. To the 2–3 µL aliquots of these dissolved lipids, internal standards were added as described previously [42 (link)]. Lipid extracts were then analyzed on a Xevo TQ-XS triple quadrupole mass spectrometer (XEVO-TQS#WAA627, Waters, UK; Milford, MA, USA). Various lipid classes and individual molecular lipid species were determined using the neutral loss, negative and positive multiple precursor ion scans as described earlier [7 (link),42 (link),43 (link)]. Data processing was performed using the TargetLynx XS™ software (Waters, UK; Milford, MA, USA) and data was normalized to lipid dry weight and represented as nmol/mg lipid dry weight.

UPLC analysis was performed on a Waters Acquity UPLC system (Waters, Milford, MA, USA). Separation was achieved on a Waters XBridge® BEH-C₁₈ XP column (130 Å, 2.5 µm, 3.0 × 100 mm, PN: 186006035) at 40°C. The mobile phase consisted of (A) acetonitrile and (B) water containing 5 mmol/L ammonium acetate, and a linear gradient elution program was applied as follows: initial, 10% A; 1 min, 10% A; 3 min, 70% A; 5 min, 90% A; 6 min, 90% A; 6.1 min, 10%; 8 min, 10% A. The mobile phase flow rate was 0.4 ml/min.
The separated compounds were analyzed by a Waters XEVO TQMS mass spectrometer (Waters, Milford, MA, USA) with an electrospray ionization source operated in negative mode (ESI⁻) for ZEN and ALS, and in positive mode (ESI⁺) for the other mycotoxins. Multiple reaction monitoring (MRM) mode was established as shown in Supplementary Table 2. The source parameters are set as follows: capillary voltage of 2.5 kV for ESI⁺ and 1.5 kV for ESI⁻, ion source temperature of 150°C, and desolvation temperature of 500°C. The gas flow rates were 7.0 bar for nebulizing gas and 1,000 L/h for desolvation gas, respectively. TargetLynx XS software was used to process the data (Waters Corporation, Milford, MA, USA).
