Detection of Ochratoxin A in white wine at the legal limit via solvent-based enrichment and selective paper-enhanced infrared spectroscopy

Key Points

• The aim is to develop a method for detecting ochratoxin A in white wine at legal limits.
• Employed solvent-based enrichment to extract ochratoxin A from the wine
• Utilized selective paper-enhanced infrared spectroscopy for analysis
• Successfully detected ochratoxin A at regulatory levels
• Demonstrated high sensitivity and specificity of the method
