A new, simple, and rapid syringe-to-syringe dispersive liquid-phase microextraction with solidified floating organic drop was used for the separation and preconcentration of ochratoxin A from grain and juice samples before its quantification using high-performance liquid chromatography and fluorescence detection. Factors influencing the microextraction efficiency of ochratoxin A, such as sample solution pH, type and volume of organic extractant, salt concentration, number of injections, and volume of the sample, were studied and optimized. Under the optimum properties, the calibration graph showed linearity in the range of 65.0-700.0 ng/L (coefficient of determination = 0.9991). The limit of detection was 20.0 ng/L. The inter-day and intra-day relative standard deviations were in the range of 5.0-8.5%. This method was successfully applied for the quantification of ochratoxin A in grain and juice samples.

A rapid, simple, and green vortex-assisted emulsification microextraction method based on solidification of floating organic drop was developed for the extraction and determination of ochratoxin A (OTA) with high-performance liquid chromatography. Some factors influencing the extraction efficiency of OTA such as the type and volume of extraction solvent, sample pH, salt concentration, vortex time, and sample volume were optimized. Under optimized conditions, the calibration curve exhibited linearity in the range of 50.0-500 ng L with a coefficient of determination higher than 0.999. The limit of detection was 15.0 ng L. The inter- and intra-assays relative standard deviations were in a range of 4.7-8.7%. The accuracy of the developed method was investigated through recovery experiments, and it was successfully used for the quantification of OTA in 40 samples of fruit juice.
