New infrared spectroscopy method detects ochratoxin A in white wine near legal limits
By
Vinetur
Right out the toaster. Reliable, with some real depth.
Summary
Researchers have developed a new label-free method using selective paper-enhanced infrared spectroscopy to detect ochratoxin A (OTA) in white wine at concentrations near the legal limit. OTA is a regulated mycotoxin with nephrotoxic and carcinogenic effects that appears in foods and beverages including wine. The method, described in the Journal of Hazardous Materials, could help wineries and testing laboratories speed up screening while maintaining regulatory compliance and consumer safety, with less laboratory complexity than existing approaches.
